==Summary ==
Setting at the Babylon Labs in Siberia, Sirin has chased down the last Schicksal personnel, immobilizing one and redirecting the last’s bullets back at him. The following day, February 2, at Air Terminal 1, Theresa is dressed up in an oreintal outfit for a picture with Kiana that Siegfried takes. Afterwards, Cecilia thanks Theresa for helping out at Kiana’s special shoot, while Theresa asks if Cecilia has recovered from giving birth, to which Cecilia responds with that she is getting better. Cecilia then asks if Theresa would like to stop by on Saturday for Siegfried’s cooking, but Theresa hastily declines. While smiling at Kiana, Theresa receives an emergency call from Otto. Meanwhile, at the Davis-Monthan Air Force Base, Welt is preparing himself to confront the 2nd Herrscher. After shattering the missile projectiles from one of his Rattlesnake mechs, Einstein shows up to inform him about the Honkai spike detected in Siberia and Schicksal’s likely plans towards it. Welt remarks that if they cannot convince the 2nd Herrscher to join them, they will be forced to end her. 
On a transport to the Tower, Theresa reviews intel on the Tower’s profile before landing in Siberia and meets up with Patricia Highsmith. After checking the Babylon Reactor Pile levels, Pat notices that five minutes of data are missing and suggests heading down to the reactor by themselves since normal people wouldn’t be able to survive the extreme levels of Honkai around the reactor. However, the two only found small traces of Honkai residue and not enough to indicate a leak. Theresa, though, is more concerned that the attack may have been conducted by a ghost, prompting Pat to sweatdrop at the fact that a veteran like Theresa would be afraid, but also recalling that Theresa had been spooked by a phantom horse at an amusement park once. Before either can expand their search, they hear a girl crying out for help. The two then discover holding cells in the sector, surprising them both, especially when they found little girls trapped in them. Without another word, Theresa rips out one cell’s door to free the children inside as she couldn’t find the key, unaware that their culprit was amongst the children. Pat then explains that Schicksal recruits thousands of orphan girls like them every year for these trials under the Advanced System Lab, nodding at the bandages on the test subjects. Theresa insists on saving them when Pat points out that it may be too late with the amount of Honkai in the girls. Theresa then explains her dream of building St. Freya High, as Otto had finally agreed to her plans and gave her an island in the Far East. Walking past Theresa, Sirin only scoffs at Theresa’s dream. As they leave, Patricia spots Honkai residue on the prison doors.
Later that night, Sirin returns to the reactor and tries to absorb the energy to replenish her strength before being interrupted by Pat. Caught, Sirin drops her act and swears vengeance on Schicksal for the pain they had caused her and the other orphans, with the Honkai injections oftentimes leading to death. Pat then senses spatial distortion around her before going missing, with only her guns and blood left at the reactor area. Otto then calls up Siegfried while deploying Salome and Niggurath, two other Snowwolf members. Meanwhile, roughly 5 km away from the tower, AE forces with Tesla and Einstein were waiting as Welt appears with a wounded Pat, who is revealed to be a double agent for AE. Pat apologizes for not being able to stop Sirin’s growth in power and hatred. Pat then requests Welt to save her Schicksal friends when he goes up against Sirin. 
Meanwhile, Sirin is struggling to drain the reactor in secret. This is when the Honkai Will contacts Sirin and explains that the Honkai will cover for her. Soon, a massive horde of 500 Honkai beasts had emerged suddenly on Schicksal’s radar, advancing in a surrounding formation against the Tower. Theresa calls for Judah but Siegfried contacts her that they’ve arrived. Outside the Tower, Siegfried and Squad Snowwolf prepare to engage the Honkai entities. Irritated at the small force, Tesla suggests sending her own mechs to just blitz their way into the Tower as Sirin was likely sapping up all the energy she can get her hands on. Welt, though, wants Siegfried to be on their side, so he tells her to wait, in order to avoid a chaotic confrontation. Welt then goes and devastates the Honkai horde, while Siegfried recalls having met Welt before. Siegfried goes on to ask why AE was there, with Welt proposing a temporary alliance to deal with the tower. Siegfried declines at first, saying that Schicksal refused to get aid from traitors, before Welt cites the Kaslana Oath. With a threat like Sirin, the weak and innocent would face a threat unlike any others and thus, regardless of allegiances, their first priority must be the safety of the world. Believing Welt to be honorable, Siegfried trusts Welt on the Tower’s threat level and agrees to the alliance. Otto is then notified of Welt’s appearance, wondering if the 1st Herrscher was Welt Joyce, since they had a nasty bout back in 1955. Otto doesn’t want AE to find the 2nd Herrscher but hears that Siegfried already accepted their help and allowed them into the tower, much to Otto’s frustration. Seeing Welt Yang, though, Otto believes that Joyce may be hiding, but senses the signatures of the 9th Divine Key, Star of Eden. Otto informs the communication team that Schicksal will cooperate with AE for the time being. Ending the call, Otto then reveals his secret battle avatar that he plans to use in this new war.
With the agreement made, Tesla is stationed 30km from the tower with her mechas, allowing Einstein to head into the Tower with Welt to meet with Siegfried and Theresa. Meanwhile, Sirin warps herself 17km away from the Tower and enters a Honkai chrysalis where she confronts her grief after losing her mother and finally ascends to a herrscher. Back inside, Theresa finally notices that Sirin has gone missing, with Welt deducing that she had teleported out much to Siegfried’s surprise. With the horrible conditions outside, neither Schicksal or AE equipment could be used to locate Sirin. Einstein then proposes using the Oath of Judah, which Theresa lends. By applying Sirin’s Honkai residue and getting Theresa to touch Judah while thinking of Sirin, they were able to locate Sirin’s general direction. However, another horde of 300 Honkai beasts arrived soon. Welt devises a plan where he, Siegfried, and Theresa head off to track down Sirin, leaving the rest behind to defend the tower since the Honkai were just a distraction from the true priority. At the same time, Sirin has fully ascended as the Herrscher of the Void. Seeing the situation is dragging out, Siegfried notifies Cecilia of his late return which Cecilia only bides him well on. She then notices a small Otto avatar at the HQ while returning home with some groceries. Otto had messed up his battle avatar’s settings and made it small, forcing him to grow a new one while trapped in his tiny form. 
Meanwhile, the Sirin tracking force finds the Honkai chrysalis, Before Theresa could fully step away from it though, she is dragged into it. Insistent on saving Theresa, Siegfried rushes in, only to watch as the chrysalis transforms into the Son of Dawn and Son of Darkness, large twin Honkai beasts. Inside the other realm, Sirin is trying to convert Theresa to her side by sharing her painful memories with her as an orphan. Aside from endless pain, Sirin herself survived the tests while her friends didn’t, solidifying her hatred as her suffering continued. Theresa apologizes for being unable to stop the other’s misery, choosing to hug Sirin. Sirin then declares that her vengeance against Schicksal will never end. Back at the Tower, Salome and Niggurath are idle as Einstein’s mechs tear apart the Honkai horde by themselves, much to Salome’s irritation. Thirty kilometers away, Tesla is still freezing out in the cold with her own mechs. As for Sirin, she had declared that her vengeance was against all Schicksal adults but makes the assumption that Theresa is a young girl like her and senses the Honkai running in Theresa’s veins, beckoning the other to join her. Theresa apologizes for Schicksal’s actions but says she cannot join her on the quest to destroy the world, pleading with Sirin to let go of her hatred. Sirin is disappointed as Theresa turns Judah on her, but drops Theresa in Lake Baikal for her to think after taking Judah. Theresa, though, uses Judah’s search feature to locate herself and retrieve her back to the realm. Theresa prepares to fight Sirin but Sirin, being in control of the space, threw a subspace lance that bypassed Judah to impale Theresa behind it. Outside the realm, Siegfried is struggling under the twin Honkai beasts, finally imploring Welt’s help. The sovereign destroys the twins and enters the empty chrysalis. Sensing an imaginary space rift, Welt rips it open to see Sirin standing over Theresa. Meanwhile, Cecilia has taken the young Otto, unaware of his identity, into the household to keep him safe from wandering around the dangerous weapons at the HQ. 
Back at the Sirin situation, Siegfried picks up Theresa to bring her medical aid after being ordered to by Welt. When Sirin tried to stop them, Welt interfered, introducing himself as the 1st herrscher. The Will talks with Siirn again, through the Honkai cherub, allowing Sirin to condemn Welt for being a false herrscher with the core of a traitor to her god. As they fight, Sirin creates multiple imaginary barriers to deflect Welt’s barrage, but he soon appears by her side and breaches the space, given their close distance. However, it is then revealed as a trap as hands appear from a portal to send Welt to Benare’s maw. Sirin then heads out to look for Siegfried and Theresa while in the distance, Otto arrives in his disguise and jester mask. It didn’t take long, however, for Welt to crawl out of Benares. Incapacitating the dragon, he then manifested a multitude of the world’s arsenals, firing them all at Sirin and even managing to start cracking her shield. Sirin counters by using her hands of typhon to crush the arsenal, only to have Welt create more with the 1st Herrscher’s powers and multiple armies. Meanwhile, Einstein tells Tesla to prepare the Silver Bullet, aka the Atomic Bomb. In an effort to destroy the forces, Sirin had then created portals to redirect their attacks back to Welt’s creations. Thus, a back and forth of recreation and destruction continued between Sirin and Welt, while the Silver Bullet was launched at their location. Finally, Sirin redirects the barrage at Welt himself, capturing him with her hands of typhon. However, while Welt is coughing up blood, Sirin realizes something was wrong before noticing the Silver Bullet descending on them. She didn’t have the powers to completely send the nuclear weapon into a pocket and it was too late to warp herself, but she did manage to redirect it to the floor below. This, however, denotes the atomic bomb and causes Sirin to completel collapse against the explosion. Approaching the weakened Sirin, Welt opts for a mercy kill, using Star of Eden’s 0th power, which calls forth a quasi-black hole, where he sends Sirin. Unfortunately, Otto arrives on time and after using the 8th Divine Key, Fenghuang Down, mimicry, deals a crippling blow to Welt before snatching the Star of Eden and crushing it. This allows Sirin to freefall back to surface as Benares frees itself from the rubble and goes to catch its queen and flee. Welt attempts to manifest projectiles to stop their escape but Otto steps on his arm, pulling out a knife to finish him off. That is until Siegfried shows up to stop him, demanding who the “clown” was because he couldn’t recognize Otto in his disguise. Otto continued his acting and through the use of Fenghuang Down’s mimicry again, he was able to slip past Siegfried and take one of Shamash’s pistols, before putting a bullet through Siegfried’s side. Otto then tries to negotiate with Siegfried, warning him that he’ll die if the wound doesn’t get treated and it’s best to just sit out and let Otto kill Welt. Siegfried objects, swearing through the pain that as a Kaslana, he can never abandon his friends. Welt, however, insists that he should just go because the world would need him, and citing that the Kaslana oath demanded Siegfried’s protection for the people - not friends. Otto also adds that since Welt is a herrscher, it would be doing humanity a favor by ending him. Siegfried ignores both of them and sucker punches Otto’s mask, cracking a part of it. With the second pistol of Shamash aimed at Otto, Siegfried explains how he never believed in self-sacrifice being necessary for others to be happy. Facing the other’s iron resolve, Otto relents as he cannot kill Siegfried just yet due to him needing Siegfried for his plans. Using Fenghuang Down’s mimicry again, Otto promptly exits, leaving his stolen Shamash pistol behind. Siegfried then managed to carry Welt back to the Tower, where Einstein treated both their wounds and allowed them to rest easy. 
While Welt was recovering, Siegfried tried looking for information on the “clown” but came up with nothing. Schicksal satellites also detected that Benares had fled to space with its queen, where their forces could not attack it. As for Sirin atop Benares, she regains consciousness as she hears the Will beckoning her to the Moon. Soon, Schicksal was notified of large Honkai emissions on the Moon’s surface. Meanwhile, Sirin arrives at the Far Side of the Moon and the ruins of the Palace of Selene, with a golden construct where she meets the Will. The Will then informs Sirin about the Previous Era and their activities, discovering that a large portion of the Final Herrscher’s powers had been trapped on the Moon thanks to the Palace. Realizing this, Sirin asks for the powers, which the Will grants, giving her four gems: Desire, Serenity, Haste, and Conquest that house powers of their respective herrscher domains, Wind, Death, Fire, and Thunder. With renewed strength, Sirin takes the four pillars of the Palace and hurls them as meteorites down towards Earth’s surface, declaring Judgment Day. One landed in Moscow, wiping out 31% of it and throwing the Soviet Union into chaos with at least 30 million casualties. Another landed in the Mariana Trench, causing tsunamis that would soon engulf coastal cities. The third one had landed in Los Angeles. WIth these latest casualties, chaos erupted around the world as the UN failed to come up with an explanation, while governments advised everyone to stay indoors as the world turned their observatories to the sky, wary of more meteorites. 
At the Tower, Amber is telling Siegfried to calm down as Otto is busily planning something to remedy these disasters, with Siegfried yelling that Sirin had been on the lunar offense for 3 days now. When Amber disconnected the call, Siegfried tried to get Welt to do something, in which Tesla replied that they had when they launched 3 Silver Bullets 60 hours prior at the Moon. The missiles, however, were all deflected by an EMP that allowed Welt to deduce that Sirin had received more powers. This EMP is then revealed to be from Benares, who has a human form now, modeled after the late Bella that had been gifted by Sirin. Because Sirin knows that humanity will not stay idle or be completely annihilated with her meteors, she begins to make a move towards destroying them one by one, starting with Welt. Sirin then commands Benares to create an EMP that encodes a message to the world, telling Welt to come to the Moon or Sirin will start throwing 4 rocks every 3 days with Welt’s absence. About two hours later, Einstein had scanned the meteor in Los Angeles and looking at the results, Welt then requested a meeting with Otto from Siegfried. Siegfried gets them the meeting but has to leave as it was a top secret meeting. Soon, Otto arrives and greets the two AE members. 
Starting the meeting, Einstein explains that AE had found multiple PE ruins throughout North America, hinting at a way to contain Honkai since it can neither be created nor destroyed. Otto claims that Schicksal also knew of the technology but could not find a way to recreate it on all the sites they possessed. This is where Einstein reveals that the structure for such technology was on the Moon, as she had analyzed the pillar remnant that landed in Los Angeles and found soulium with that information. Welt then proposes that Otto send an agent with him to collect soulium on the Moon while he distracts Sirin. Otto digresses and says the plan is too risky, since AE likely didn’t have a way to recreate the tech that can contain Honkai. However, Welt points out that Otto probably didn’t have another solution to over Sirin’s advantage on the Moon and adds something else quietly which gets Otto to laugh before agreeing. 
Outside, Siegfried is doing 500 pushups in the gym and condemning himself for having to run away during Welt and Sirin’s first confrontation, believing that the millions of deaths and meteorites would have been prevented if he had been there to aid Welt. Welt then comes out and informs Siegfried that he’ll be coming with him to the Moon, and Siegfried swears to do everything he can to stop Sirin, unaware that he was only there to collect soulium and “run away” again. The next day at the Yellowstone base, Raiden Ryoma greets his sovereign before looking at Siegfried in distrust. Welt, though, just leads Siegfried into the base, revealing that the Arahato mech is real and that it will be taking them to the Moon. Siegfried completely enters fanboy mode when Welt says that he and AE had made the anime to give them additional funding. Later, Welt explains the plan in full to Siegfried and when the Kaslana realizes he’ll have to leave Welt on the Moon against Sirin for the safest plan, he enters a frustrated rage as Welt leaves him with his choices. Before Welt departs for the Moon, he visits Tesla once again, who asks him to have their dance that he had promised to her when he was young. Meanwhile, Siegfried is in a call with Kiana and Cecilia, promising his daughter that he will be fine and will return quickly. After sending Kiana off, Cecilia then implores about the severity of the mission which Siegfried brushes aside and says that he’ll definitely return safely. However, with the difficult choice he has to make, Siegfried tries to get Cecilia’s advice on it before failing to form the question and ending the call. Cecilia, though, knows her husband and messaged him that she believed he would make the right choice even if it was painful for him to do so since he wanted to protect everyone, so she will bear the pain with him together.
Later that night, Arahato is loaded into an Atlas rocket that will power it through the atmosphere while Welt and Siegfried board it. Soon, Arahato was in orbit as Kiana and Cecilia watched back down on Earth. As he looked down at his home, Siegfried began to appreciate Earth more as the belief in humanity’s better future solidified in his mind. On their journey, Welt offers a bottle of beer, which accidentally floats into Siegfried’s face due to the lack of gravity, much to the two’s amusement. The two then talked a bit, realizing that they both had run from home when they were kids, but also having differences like Siegfried’s more modern tastes to Welt’s antique tastes in entertainment. They talked about everything but the choice that Siegfried will make on the 48 hour trip. Roughly 10 minutes before Arahato landed in the Taurus-Littrow Valley on the Moon, Welt received the final piece of his plan from Tesla. Welt then exits the mech without his suit, which surprises Siegfried before he remembered that Welt was a herrscher. Soon, Benares appeared before Welt as Bella. Because space didn’t communicate sound, Benares had to communicate directly with Welt’s mind, saying that she will lead him to her queen, while Welt notes that “Bella” is more than a Honkai beast but not quite a herrscher. It is revealed here that an hour prior to the launch, Einstein had informed Siegfried what soulium looked like and how Welt will be planning to lure Sirin away from the palace ruins so he could go and collect it. Originally the ruins had been too dangerous to enter due to the large amounts of Honkai surrounding it, but thanks to Siegfried’s innate Honkai resistance, he is able to enter them safely. 
At the meeting with Welt, Sirin offers amnesty to him in exchange that he swears absolutely loyalty to her. Welt only declines and recreates a Star of Eden. When Sirin tried to strike him, Welt evaded and taunted her, enraging Sirin as she and Benares chased after him. Meanwhile, Ziggy has begun extracting soulium fragments at the heart of the ruins. Benares realizes later that Welt is trying to distract them and politely warns Sirin who says she already knew. She then stops, causing Welt to stop warily before warping space around him and porting him towards her. As they were close, Welt uses Star of Eden’s 0th again to summon a quasi black hole between them but Sirin easily suppresses the hole with multiple hands of typhons. Fifty-eight minutes later, Siegfried had finished his extraction and chose to follow Plan B, leaving Welt on the Moon. Before that, his younger self argued with him in favor of fighting Sirin but Siegfried says he had respected Welt’s choice as he knew that he would have done the same thing. Back with Sirin, she applauds Welt’s ability to hold out for a minute against her before managing to end the quasi black hole, sending Welt crashing into the lunar surface. 
About 50 hours prior to the battle, Welt had conversed with Einstein on how to buy Siegfried at least 30 minutes for the extraction. At the time, Einstein had just finished conducting a full health scan of Welt’s current shape, noting that many organs still remained damaged, with Welt being able to sustain only 47% of his herrscher powers and 70% of his Honkai adaptability missing. This would only allow him to fight Sirin with his herrscher powers for 5 minutes before he cascaded. However, by using the event horizon of black holes, any entity closest to it will face time dilation, where one minute is equivalent to 60-65 minutes to those away from the black hole. Thus, in the present time, Welt had successfully bought an hour of time for Siegfried even though Sirin had believed it to be only a minute. Sirin is then notified of the true passing of time by Benares and flies into rage, firing 4 new meteors towards Earth. In a last ditch effort, Welt manifests multiple human arsenals to destroy the meteors as Sirin hurls them. After stopping the meteor attacks, Welt is completely spent as he keels on the Moon. Sirin feigns pity for him as she struts over to take his core away. However, it is revealed that the final piece of his plan that Tesla gave him was teaching him how to detonate the core so Sirin wouldn’t be able to have it. At first, when Welt had proposed the plan back down on Earth about 51 hours ago, Tesla had been unwilling, hurling a stuffed bull at him as she accused him of hurting those that cared about him by throwing away his life. However, when the Arahato had landed, Tesla had forwarded him the Chandrasekhar Limit, which is 14 solar masses. If he uses his gravitational powers beyond this limit, it will initiate core collapse and he will go supernova, turning everything around him into atoms. To ensure Sirin dies, Welt also plans on forcing Sirin’s core to collapse as well, taking them both out. Unfortunately, Sirin rips Welt’s core out of him quickly before he could surpass the limit, instantly crippling him. With the core in hand, Sirin planned to leave Welt to die alone on the Moon but the sovereign stands and stumbles forward before dissipating from the space. Believing Welt to be dead, Sirin consumes the core and triumphantly declares her return to Earth and humanity’s devastation by their own weapons as she wields the Reason powers finally.
Back down on Earth, it had been a few hours since the last conflict on the Moon, leaving the planet in uneasy peace with Patricia keeping an eye on the sky. It is then, above the Tower, that a 20th century warship descends with both Sirin and Benares onboard as well as 13000 Honkai beasts. The Schicksal and AE forces below then began to mobilize. Inside the Tower, Salome has already ordered Niggurath to focus priority on escaping the tower with all of Schicksal’s important assets since the fight was likewise unwinnable. Unbeknownst to them, Sirin had already deployed Benares and several Honkai beasts to stop them. As the two plan to leave the G-2 Warehouse of the Tower, they are notified that the beasts had surrounded all exits besides one. Despite knowing it was likely a trap, Salome orders the convoys to flee from the only exit, while an injured Pat remains at the top of the Tower wishing them well before a Honkai beast finishes her off. Noticing the fleeing convoys, Benares launches a volley of lightning that was soon hastily blocked by Salome’s Halo of the Twelve. Unfortunately, the collision was too powerful and sent Salome flying off her convoy, falling dead into the snow. Despite wanting to stop to retrieve Salome, Niggurath recalls the top priority instructed by the late valkyrie and continues to flee with the rest of the surviving convoys. Meanwhile, Sirin has descended and visited her late friends’ grave to sing their song one last time.
Two days later, February 14th, three new “angels” descended, named after Sirin’s late friends. At 9:10 Oulu, Finland, the Prince of Desire, “Avrora”, descends, creating a massive storm of multiple tornadoes towards the city. At 4:30 Astana, Kazakhstan, the Prince of Haste, “Agata”, descends, cutting through a large MiHoYo tower as fire is set on the collision site. At 12:10 Novosibirsk, Russia, the Prince of Serenity descends, apologizing as she lumbers towards the civilians, leaving death vapors in her wake that begin to consume everyone around her. Back in Siberia, Sirin is gleefully realizing her new accumulation of strength as more cities burning continue to feed her powers. She then leaves for the Moon as she instructs Benares to guard the Tower, who swears to, with her life. Meanwhile, Niggurath’s convoys had successfully reached the Belarus-Poland border as they await their support while Honkai beasts advanced towards them. Luckily, Lixue arrives on time, ordering Niggurath to take the survivors back to HQ as Otto had ordered every B ranker or higher of their Europe branch to mobilize with a war council being declared. Lixue then calls Cecilia to notify her that Niggurath is safe. However, due to their Overseer’s orders, Cecilia is recalled from her temporary leave to join the war effort, tucking Kiana into bed as Amber arrives at her house to receive her. Meanwhile, Otto is contemplating his next actions as he observes the damage reports done by the three Princes, noting that each seemed to host Honkai emissions equal to 50% of the Sirin they observed in Siberia the first time. Otto also contemplates if Sirin is the Herrscher of Death while Fu Hua arrives finally, due to his recall. Later, Otto takes the Oath of Judah to Theresa, who had locked up in Training Cabin 3 at HQ, so she can practice mastering Judah’s 0th, which creates a field that can negate all Honkai reactions. Because Theresa had Honkai beast genes, Judah could potentially kill her as well if she didn’t master it, hence why Otto didn’t tell her about 0th until now. At the same time, Siegfried has landed Arahato back at the Yellowstone base, handing Tesla the collected soulium case as she falls into tears. Inside the base, Siegfried is resting when he hears the news of the Prince of Desire in Finland, and he leaps into action, trying to return to protect his family. However, Einstein stops him to inform him about some additional data on the Kaslana family that she had managed to find in some of the soulium fragments. 
At the Valkyrie Residence on a Floating Island at HQ, Lixue is playing the zither with a somber tone before sensing the arrival of someone familiar. Soon enough, in the common area, Fu Hua had arrived and was peering at a painting of Fuxi and Nuwa that Lixue had painted. Lixue happily greets her master, inviting Hua for a cup of tea. However, Hua only politely declines, remarking the heaviness in Lixue’s zither tunes as she reassures Lixue that everything will be fine before leaving. Outside, Hua looks skyward, sighing at the passage of time and how much Lixue had grown. As for Cecilia, she soon arrives at the training cabin to warm herself up, interrupting Niggurath’s Level 10 simulation to ask for a spar. Niggurath agrees to train with her squad leader but is soon quickly defeated, unable to stand a hit from Cecilia. Lamenting at her weaknesses, Niggurath breaks down at her failure to save Salome while Cecilia comforts her. Hours later, on the Floating Island, the Valkyrie Order has finally assembled in full, listening to Otto’s war speech and plan. Watching from above Otto’s stage, Hua only remarks under her breath, questioning Otto’s earnesty in saving humanity. As Otto finishes, Amber then informs him that AE wanted to talk.
In her message to Otto, Einstein says that the soulium fragments needed a genetic key to decrypt the data, which is only held by a member of House Kaslana. She requests for Siegfried to remain with AE for the next 24 hours while they decrypt the information and Otto will get a copy, too, once they’re done. Realizing that Welt isn’t mentioned in the message, Otto scoffs at Welt’s sacrifice for the “ingrates” and dismisses AE as a threat after contemplating ordering Siegfried to steal the soulium fragments. Otto then tells Amber to pen his reply, agreeing to Einstein’s request as he went to fully tune his battle avatar for his pursuit of the “Herrscher of Death.” At AE, Einstein apologizes for keeping Siegfried for so long, and he waves it off, saying that he owed Welt one for sacrificing his life to acquire the fragments in the first place. After successfully matching the genetic key, Einstein sends Siegfried into the data space, as she searches for entries relating to the term, Honkai, contain, or seal. An entry was located and the space around Siegfried’s mental avatar is contorted to the Moon, during the Previous Era’s battle with the Final Herrscher.
At the same time, in Novosibirsk, Amber has arrived with a squad of valkyries to find the Prince of Serenity. However, the Prince evades the squad and takes them out one by one, by removing their masks which allow them to withstand her vapors. Amber is the last one standing before her mask is also removed, causing her to keel as the vapors overtake her. As for Lixue’s forces, she has arrived to combat the Prince of Haste. In preparation for her encounter, Lixue recalls the training she received from Hua and recites the Blade Heart. However, because of her restless angst at why Hua left her years ago, she was unable to fully prepare Blade Heart. Soon, her forces interrupted her meditation, to notify her that the Prince of Haste had taken the bait. Lixue then orders them to retreat as she would now solo the Prince alone, in an effort to make Hua proud. In her hand, Lixue wields one of the 10th Divine Keys, whose form becomes Water’s Edge in her grip. Unfortunately, the tidal waves of Water’s Edge were vaporized when the Prince unleashed a 5000 Kelvin plasma jet, which also shattered the sword. Lixue is then defenseless as the Prince fires a plasma shot through her side. Meanwhile, at Kiel, Germany at 14:00, the windstorm from the Prince of Desire is now crossing the Baltic Sea after devastating several Finnish cities. Lewis Peppers, leader of the Ground Forces, orders her troops to start firing at the Prince. None of the missiles penetrated the wind barrier but the Prince did start reacting to the onslaught. Because of this, her emission was tracked by Shigure Kira from the Battle Command, who forwarded the coordinates of the Prince to Cecilia, who is onboard Helios, one of Schicksal’s space shuttles. Helios nears the optimal strike point but Cecilia jumps off 7 secs earlier, much to Kira’s dismay. However, Cecilia still manages to penetrate the storm, striking the Prince of Desire from above. The Prince quickly creates a new barrier above her, but Cecilia then throws Abyss Flower, the Divine Key, piercing through the barrier and through the Prince herself, hitting the ground below. The Prince slowly disintegrates in her shock as she registers her death to Sirin. In freefall now, Cecilia wills the divine key’s “Flower” part to grow into a large plant that catches her, reporting her mission’s success.
Meanwhile, Lixue is barely standing her ground after the plasma beam shot, while the Prince of Desire advances, feigning pity. Before she could finish Lixue off, though, Lixue quickly opts towards Stances of the Six Fists for close combat as she hurls the Prince to the ground and strikes her. Enraged now, the Prince beats a hasty retreat as she launches a barrage of flames everywhere, hoping they had engulfed Lixue. This is when Hua emerges, having used the actual Fenghuang Down to quickly carry Lixue to safety. Hua and the Prince then enter a mind realm, unbeknownst to the Prince, where Hua unleashes an onslaught of mental attacks, convincing the Prince that she had died to Hua. In the real world, Hua hasn’t moved from Lixue’s side and is busily healing the plasma wound despite Lixue’s protests that the Prince might stir. Hua only reassures her that the Prince will never stir again before one of Sirin’s hands of typhons quickly snatches the Prince’s corpse away, stunning Hua. As for Amber, it’s been 15 minutes since her squad has set foot into the ruined city, and her arms up to her elbow have disintegrated, revealing the wires under her skin. Unable to withstand the pain any longer, Amber falls, but Otto arrives to catch her. He then uses an Abyss Flower mimicry to cleanse Amber of the vapors before ordering her to return to base. Seeing how Otto wasn’t dying, the Prince of Serenity tries to flee in fear, only to be baited by Otto giving her a homu doll. The Prince takes the doll but it disintegrates in her hands due to her powers. Her dismay at being unable to control her powers was the opening Otto needed, to use his Fenghuang Down’s mimicry on her and take over her mind. Inside, Void Archives mocks his intel techniques, informing him that the Prince only had a fraction of the true Herrscher of Death’s powers. After scanning her mind, Otto concludes that the Prince is nothing more than a puppet so he seized her core - only to find out the core is a copy, with Sirin still having the real gem. As Sirin’s hands come to retrieve her Prince, Otto stops her by using Shamash’s mimicry, swearing that nothing will get in the way of his obsession with Kallen’s revival. 
Back with Siegfried, the battle with the Final Herrscher plays out, with two of the warriors dying in 5 minutes. Dr. MEI fires Selene but it only turns 2% of the Final Herrscher’s Honkai energy into useless heat, thus she lifts all safety hatches on Selene, allowing it to work at 200% power, which tears 30% of the Final Herrscher’s Honkai reserves off that seep into the Moon’s crust. This, however, completely fries Selene and renders it useless. Kevin then unleashed a blow that immobilized the Final Herrscher as humanity makes a hasty retreat. With that, the data entry ends, and Einstein thanks Siegfried for helping her gather the data on the Selene. As a request, Siegfried asks to replay the part where Kevin was standing on the Moon with Shamash fully unleashed. Curious as to why the flames weren’t harming Kevin, Siegfried approaches the data Kevin which then reacts out of the replay, greeting Siegfried as his progeny. He then stabs Siegfried with the data space Shamash, activating his dormant Honkai genes. Siegfried snaps from the data space, shoving Einstein aside as Parvati’s genes run through him. When he finally gains control of himself 45 minutes later, Siegfried had created a large icicle in the lab, apologizing to Einstein, who brought him a cup of coffee. The scientist then explains to Siegfried that an ancestor of his likely got Honkai genes that became dormant over the generations. Siegfried agrees and insists on finding a way to activate the genes, in which Einstein only replies by asking how the coffee was. Siegfried answers honestly that the coffee was bland and cold before Einstein told him it was boiling hot. The activated genes had lowered Siegfried’s body temperature and compromised his senses. Still confused, Einstein continues to explain to Siegfried that the Previous Era had MANTISes, Massively Augmented Neo-Tech Integrated Soldiers, who had recombinant DNA with Honkai genes known as meta-morph ICHOR. Meta-morph Activators can be used to express the ICHOR fully, but at the risk of cascade. AE only managed to retrieve 3 vials of the activators and don’t know how to make the ICHOR or the activators yet. While Siegfried wants to take the activator, Einstein warns him that a cascade will transform him into a full Honkai beast before leaving him to his own rationale.
As for Sirin, the herrscher has returned to the Tower and is irritated with the Prince of Haste’s condition, due to humanity “mimicking God’s power”, which she had read about in the soulium. Regardless, Sirin is still triumphant after absorbing the results of the cities’ devastation and initiates another eruption that surpasses the intensity of the Berlin Eruption of 1952 with the Herrscher of Reason. The high Honkai intentinsity zone begins to spread outwards at 200 kph, forcing Otto to take the battle to Sirin or risk Siberia’s total destruction. Meanwhile, in a holding cell, Cocolia has been arrested for attacking Alexey Zaychik when she found him smuggling their military’s arms for the black market, a few weeks prior. Little did she know, the entire Siberian military district had been in on it, as a means of survival due to the majority of Russia ignoring them, hence her imprisonment. The Zaychik had explained to Cocolia that his daughter will soon be born in August and in order to feed his family, he had to find better pay, which was through these arm trades. Alexey continues to offer her to join them in order to help support the local orphanages that Cocolia cared so much about as well as warning her that strange things were happening in Siberia. Cocolia doesn’t believe him and refuses to turn her back on the Soviet Union, until the eruption zone reaches them, exploding the entire compound. Alexey dies as he’s crushed by a fallen wall, as Cocolia realizes he was right and quickly rushes out to see where he had left his car. Inside, Alexey’s pregnant wife, Alexandra, panics, seeing the unfamiliar woman with her husband’s car keys, but Cocolia is quick to order her to calm down before driving them both quickly away from the incoming Honkai beasts. In Sirin’s eruption, half of a million Honkai beasts stormed the entire Siberian tundra, with less than 1000 residents surviving. 
Later that day, Siegfried arrives back at Schicksal HQ, where he is greeted by Amber, who informs him that Cecilia has already been deployed and that he, too, was expected to be deployed in 2 hours for North Siberia. With his limited time, he heads back to the Kaslana residence to see his daughter. However, as he comforts her sleeping form, he hallucinates that his hand had started to express Parvati genes, quickly exiting the room as Kiana wakes. Soon, the mission briefing begins, explaining how the Honkai had managed to cover all of Siberia within 3 hours since the eruption. Because of high Honkai levels, Schicksal satellites are unable to locate Sirin, so they will be deploying two formations. N-1 to the north, led by Siegfried and containing 250 European valkyries, and S-1 to the south, with 212 valkyries from the Oceania and Africa branches led by Cecilia. Both formations will sweep in at 10:00 Feburary 17th to locate Sirin after the Siberian tundra is carpet bombed at 8:00, which will destroy about 90% of the Honkai forces. There will be a camp, W-1 to the west with Otto, Lixue, and 10 valkyrie paladins, that will lend support when needed. Meanwhile, Cocolia has managed to keep Alexandra and herself safe until Feb 17th at 7:30 in Southern Siberia, where they have been surrounded by Honkai beasts. Luckily, Cecilia arrives on time and saves them. Cocolia is stunned, believing Cecilia to be a soldier from one of the USSR’s secret projects, but Cecilia doesn’t understand much of it since Cocolia is speaking Russian, with Cecilia’s Russian being pretty bad. Cocolia then switches to speaking English on Cecilia’s request and realizes that Cecilia is likely from a foreign army. Cecilia radios Otto for evacuation permission, and approves, but warns her to stop patrolling the area with her formation since they were against his plans and that the area will be bombed soon. Cecilia relents, but her forces did manage to save a few survivors from the region before everything was bombed. 
Once evacuated, Cocolia has been informed of the truth behind the disaster events, with Novosibirsk not being a “gas leak” and Moskov not being hit by normal meteors. Cocolia, though, refuses to run away like much of the Union hoping to overcome this apocalypse. In order to overcome the Honkai’s numerative advantage, Otto had depleted his entire strategic arsenal for a one hour carpet bomb of Siberia. After the bombing, the Soviet army tries to get in Valkyrie's way by throwing thermobarics around the tundra, setting everything ablaze. As for the Honkai, there are still 50,000 beasts remaining as well as Benares, who descend on Siegfried’s formation. At the top of the Tower, Sirin muses at Schicksal’s efforts, commenting that she could simply make more Honkai beasts. Sensing a presence behind her, Sirin turns as she greets Lixue, Fu Hua, and Otto, noting that the N-1 and S-1 formations were mere distractions.
As Fu Hua steps forward to fight her alone, Sirin gets offended, unaware that she had fallen into Fenghuang Down’s dream world already. Also doubtful, Lixue questions if it’s safe for her master to combat Sirin alone, prompting Otto to assure her as he remarks to himself that Hua was simply the most powerful being in her own dream world. In the world, Hua commentates over every action, with Sirin unknowingly doing everything Hua narrates, before the narrative is then turned against Sirin, building up the weakening resolve of the 2nd Herrscher. At first, Sirin had deflected all of Hua’s attacks without much thought, allowing Sirin to believe the illusion to be real, before Hua used the illusion to convince Sirin that she was attacking her from all sides and had more power than she really did in the real world. As she lands a hit on Sirin, the herrscher panics and believes she had hurled the vapors of Serenity, which Hua counters by convincing Sirin that she was immune. Hua then borrows Water’s Edge from the dreamworld Lixue and knocks Sirin off the dreamworld Tower. Hua soon overwhelms Sirin with her experiences and convinces Sirin that she had been gravely injured by Hua. 
With Sirin under control, Otto then enters the dream world and uses his own Fenghuang Down mimicry to create another dream world inside Sirin’s mind, where he is able to investigate Sirin’s powers. Hua allows Otto some time to explore but warns him that he must be quick since they had to kill Sirin soon before she somehow regains consciousness. Inside Sirin’s mind, Otto is able to see Sirin’s traumatic past, where she lost her mother on the sickbed, leaving her as an orphan. Otto then modifies the memory so that Sirin’s mother is begging Sirin to save her instead of wishing Sirin to live well. Sirin “wakes” up in the dream world from the nightmare, and Otto, disguised as Benares in the dream world, tells Sirin that he had retrieved what she wanted, which were her late mother’s clothes. Convinced that she was planning to revive her mother, Sirin then instructs “Benares” to come with her to the revival place. After much processing, Sirin recreated the body of her mother but still lacked her soul. Disappointed, Otto tries to get Sirin to try again but the other collapses and asks the question that had baffled Otto for centuries: What is a soul? Sirin answers for him by suggesting to go see her God. Despite knowing the risks of it, and losing patience, Otto agrees to the suggestion. Outside in her own dream world, Fu Hua is getting more anxious as Otto takes longer than she anticipated, once again, hurrying Otto. Otto only reassures her as he senses the answer to his centuries long question, nearing. Soon, Sirin called for her God and a beam of light envelops both Sirin and Otto, taking Otto to a pristine white space where the Will of Honkai knelt by a cross. Sensing Otto, the Will stands as it takes on Otto’s appearance, looking at him. Otto bows before the Will, giving his request while he quietly manifests Shamash’ mimicry behind his back, wary of what the Will might do. Before he gets his own hopes up, Otto wants the Will to prove it's a God. However, before he could even ask the question, the Will already knew, overwhelming Otto with its knowledge. After the influx of knowledge, Otto is kneeling before the Will, understanding why the Will chose to help him as beings like it, saw humanity as humans would to ants. Begging the Will to answer his question on Kallen’s revival, the Will replies by showing all of Otto’s misdeeds he did over the centuries. Otto tries to defend himself before ultimately surrendering, stating that he wouldn’t regret his actions now that he was so close to the answer. The Will finally smiles as it takes a crucifix necklace and drives it through its Otto form’s neck, smiling madly. Confused, Otto didn’t have much time to think of it as he is casted out of all the spaces. In the real world, Otto is frustrated when he can’t remember any of the knowledge the Will gave him aside from the part when it stabbed itself.
Meanwhile, in Fu Hua’s dream world, Sirin stirs after being informed by the Will about Fenghuang Down’s ability. Crushing several of the feathers, Sirin curses Hua for “cheating” in their battle as she begins to freely interact with the dream world without Fenghuang Down’s manipulation, hurling attacks at Hua’s mental avatar. In a last ditch effort, Hua supercharges Fenghuang with her memories, creating the Sunder of Reality, which is an upgraded form of the Edge of Taixuan’s Eminence. This attack shatters the entire dream world Tower, but fails to take out Sirin. This is because the Will interferes as Sirin calls upon it, shattering the mental link between it and Sirin, instead. Realizing what happened but also depleted of her strength, Hua falls unconscious in the dream world as Welt catches her. After his defeat on the Moon, Welt had hid himself in his herrscher core after his physical form was destroyed. This is because the Reason core already housed 300,000 personality fragments of Berlin’s victims that refused to bend to the Will of the Honkai, which meant that Welt could also place his own fragment in there with sufficient Honkai energy; and he succeeded. However, the Will of Honkai in Sirin’s mind was able to suppress him for a long time before Hua broke the link. After bidding the unconscious Hua well, Welt returns to hiding, hoping to not be noticed by Sirin that he was in her mind space. In the real world, Hua stumbles forth, coughing up blood as Lixue rushes to her side, confused about what happened. Hua, though, only pushes her away, telling her to run as the battle has been lost. Hua then apologizes for not knowing who Lixue was anymore due to her burnt memories but believed Lixue to be important to her so she had to live before passing out. Lixue catches her gently, telling her that she wouldn’t run from this and that she would now protect Hua. Approaching Otto, Lixue puts her unconscious master in Otto’s hands and tells him to run, which he does as Lixue hardens her resolve, turning to face Sirin alone. 
After carrying Hua quite a distance, Otto notes how Hua had spent over half of Fenghuang Down in that fight against Sirin, cursing the hide and seek game he had to play with the Honkai now that Hua was unconscious, and he was unable to summon Void Archives after contacting the Will. As for Sirin, she had successfully killed Lixue now but the latter had managed to buy Otto and Hua enough time to escape. Waving the irritation aside, Sirin discovers that Fenghuang Down has been left behind, allowing her to take control of it to create her own dream world. Meanwhile, in Southern Siberia with Cecilia’s formation, the forces were hard pressed as they tried to carry their wounded back. Had it not been for Cecilia’s combat prowess, their formation would have already been defeated. This is why Sirin casted a portal to nab Cecilia as she eludes her into a dream with Fenghuang Down, leaving only Abyss Flower on the battlefield. At the same time, with Siegfried’s formation, Siegfried had managed to lure Benares away from his forces, dealing a devastating blow with Shamash that ruined one of Benares’ wings. Siegfried had used one of his activators and was now expressing some of Parvati genes on the left side of the body, but is still recovering from unleashing the blow. Both stared each other down before Sirin manages to nab Siegfried from the battlefield as well, placing his mind in the dream world with Cecilia as Shamash hits the battlefield. Benares apologizes for her weakness before swearing to kill every other valkyrie in Siegfried’s formation.
Back at Schicksal HQ, Amber is struggling to make orders in the face of the countless bad reports from both N-1 and S-1 formations without their leaders. Since Otto is also MIA, Amber starts speculating about the use of the Rebirth program, before Theresa appears, having finished her mastery with Judah. Meanwhile, Sirin realizes that she lost contact with her god and panics. Inside the dream world, Siegfried “wakes” from a “nightmare” about activating his ichor and curses himself for having the dream about the event that happened “years ago.” In this dream world, it was several years after the 2nd Honkai War had ended peacefully and a day before Kiana’s nth birthday. With the Honkai, Schicksal had little use, thus, Otto in this dream forms a company, MiHoYo, for the former Schicksal personnel to work at. After Siegfried greets Patricia at the reception desk, he is directed to his proposal meeting where he passes by Salome and Niggurath, as programmers, who are gossiping about the game industry and Otto’s hair loss, while Shigure, as the operations lead, is cursing the writer for the new event story. Upon arriving in the room, Siegfried is met with Otto, founder and CEO, and Lixue, the Vice President. Siegfried then unironically proposes making Honkai Impact 3 as his game pitch for Otto, who accepts it. In this dream world, Siegfried is also the unironic lead designer for Guns Girl Z. Meanwhile, Cecilia has gotten a now adolescent Kiana in her prom dress as she tells her the “magic words”, ich liebe dich (I love you, in German). Watching these events was Sirin, who was frustrated that the feather hadn’t created the nightmare world that she wanted them to have. However, seeing their happy and content family, Sirin deflates as her mind begins to wistfully think what would have happened if her own mother hadn’t died and if she, too, could have led a happy life with a happy family. 
At the birthday party in the dream world, Theresa gives Kiana a large Homu plush and Siegfried gives her a “DS4” much to Cecilia’s disapproval as she refers to Kiana’s failing midterm grades. However, Kiana gives her the sad puppy eyes and Cecilia relents to letting her play on it for only an hour a day. After seeing Theresa off, Siegfried is then forced to do the dishes by Cecilia because it was his turn. In the real world, Sirin is furious at her Fenghuang Down feather but also saddened that she never got a cake before. With that thought, Sirin gets sent into the dream world in school attire, much to her own surprise. Hearing a commotion outside, Siegfried then opens the door again and questions who Sirin was. Sirin, though, is finally satisfied at the feather’s work as she can now personally destroy the family’s happiness. However, before she could do that, Cecilia interrupts both Siegfried and Sirin, asking her husband why they were upset with their second daughter, catching the two both off guard. Cecilia only chides Siegfried for getting too drunk to recognize “their daughter”, Sirin and explains that Sirin had called earlier and said she was going to be late due to school activities. Cecilia then invites Sirin in, who believes that the situation was created by the feather. After having cake, Sirin begins to cry as she remembers the time when her own mother had given her cake when she was still around. Cecilia comforts Sirin and tells her, under the impression that Sirin was upset for missing Kiana’s birthday party. The dream world then created a room in the house for Sirin, leading Siegfried to feel bad for “sending Sirin to boarding school and forgetting her existence.” Listening to Siegfried’s apologies, Sirin is curled in her room, wondering why she hadn’t killed the two already. However, Cecilia then appears by her side, also apologizing for Siegfried’s “forgetfulness” and embraces the other to sleep. 
When Sirin wakes, she scolds herself for having fallen asleep in her own dream world but recalls to herself that she never really had a good night’s sleep since she was sent to the lab. Before Sirin could contemplate her next actions, Cecilia quickly whisps Sirin out for shopping. Some time later, Siegfried gets off working on the Honkai video game and heads to the store to get something nice for his daughters. There, he finds an Arahato candy bar and a familiar voice interrupts his thoughts. Turning, he sees the real Welt, telling him to wake from this dream, much to Siegfried’s confusion as he felt that he knew Welt. Welt then leaves and the illusion returns to normal. Later, the trio of Siegfried, Cecilia, and Sirin are at the mall, with Cecilia whisking Sirin through every store and activity, burdening Siegfried with more and more of the bought gifts. Eventually, the two end up in a fashion store while Siegfried waits outside, catching his breath. However, Welt appears before Siegfried again and tells him to wake up as the real world crisis was still ongoing against the Honkai horde. Siegfried’s ichor is expressed again as the dream world is restored and the store’s windows shatter. Inside, Sirin has tried on multiple dresses at Cecilia’s expense and when Cecilia expresses pride and offers a hug, Sirin backs away, hesitant on accepting Cecilia as a mother figure. Yet when the glass shattered, Cecilia dove for Sirin to shield her, while injuring herself as Sirin heard the three magic words: ich liebe dich. Deep down, Sirin slowly begins to accept Cecilia as a mother figure as the mall apologies for the “gas explosion” to the family at the hospital. Meanwhile, in the real world, the valkyries in the southern front are struggling to retreat against the Honkai horde’s advances before Tesla arrives with her mechs, having reached an agreement with Theresa, who took on the role of their acting commander. 
As for Einstein, she had brought the prototype of Selene, operating at 10% power, as the Arahato’s engine. Soon, she and Tesla received the signal from Welt that Sirin was incapicated (due to being sent into her own dream world) and the Arahato, with Einstein as its pilot, rushed for the 2nd Herrscher’s location. Meanwhile, on the northern front, Kira has managed to hold onto Abyss Flower and Shamash, with Niggurath ordering her to find Siegfried and Cecilia to return their divine keys back. Kira’s arm though, had been affected by the Abyss Flower once she touched it, but still goes regardless as Niggurath faces down Benares. Luckily for her, Theresa arrives on time, wielding the Oath of Judah. However, Theresa is running out of time for the operation by AE and couldn’t waste it fighting Benares. Niggurath and Kira give Theresa both Shamash and Abyss Flower, telling her to locate their rightful owners as the two A-ranker veterans deal with Benares. Benares senses something terrible about Judah and upon watching Theresa hoverboard away on Judah with all three divine keys, realizes she was going to kill Sirin. As she tries to stop Theresa, Kira binds her down with her own electric field that negates Benares’ humanoid lightning powers. Enraged, Benares returns to her Honkai beast form, revealing her charred left wing from Shamash’ blow earlier. As Benares prepares to blow Kira into smithereens, Niggurath leaps on top of the dragon Honkai beast and drives her spear through Benares’ wound left by Shamash. It is then revealed that after Benares’ wound from Welt, it had spent all of its remaining strength getting Sirin to the Moon. Because of this, Sirin had been upset that her loyal Honkai beast was dying, thus bestowing her the humanoid form “Bella” and a “girl’s soul” when she crafted a pseudo core for her. Soon, Niggurath had driven her spear into the crack in Benares’ armor, and even though the effort started to eat her strength, Niggurath saw Salome one last time, which was enough to encourage her to finish the job, driving them both into the ground. As Niggurath dies from overexertion, Benares staggers to its feet weekly, her soul weeping as it tries to return to its queen and prevent its pseudo-core from breaking. In an effort to stop the beast from escaping, Kira tries to chase after but ultimately passes out due to the Abyss Flower infection from before. As for “Bella”, she didn’t want to become a mindless beast again nor did she want to leave her queen behind, spending the last of her strength only to make it to a body of water and fall through as her pseudo-core breaks.
Deep within the dream world, Sirin is talking with her Bella plush doll, confiding in her on her conflicted feelings on Cecilia. However, Sirin soon senses “Bella’s” departure with the broken pseudo-core and flies into rage, especially when Siegfried knocks on her bedroom door to see if she is ok. Believing Siegfried to be the main cause of Benares’ absence, Sirin resumes her herrscher form as she attacks him through her door, spearing him on a void lance as he’s thrown out of the house. Before she could finish him off, though, Cecilia arrives, hauling Siegfried to safety as she scolds Sirin for attacking her own “father.” However, Sirin then realizes that Cecilia’s reaction was too fast and that she appeared to know more than what Fenghuang Down should have shown her, falling back into a miserable rage at Cecilia’s act. Cecilia tries to reason with her, but Welt arrives in time, quickly immobilizing Sirin as he helps Cecilia carry Siegfried to safety. After healing Siegfried’s wound momentarily, Cecilia and Welt finally introduce themselves to one another as Welt questions how Cecilia was so resistant to the effects of Fenghuang Down. Cecilia reveals that Fu Hua had done some training with her using Fenghuang Down, hence why Cecilia knew it was a dream from the get go but played along anyways. Sirin soon hunts them down, though, and refuses to let any of them leave the mind space, which leaves the only option of escape being knocking her out. In the real world, Arahato has arrived where Sirin’s real body is and has surrounded her with the Selene. 
After blasting Sirin’s real body, a portal manifested in the mind space for Cecilia and Siegfried to escape, leaving Welt to stall Sirin. As they leave, Siegfried stirs and realizes that Welt hasn’t died, bidding him well on his next act of heroics. The Kaslana couple then wake at the Tower, having been teleported there by Sirin when they were kidnapped earlier, and are instantly greeted by Theresa who was busily trying to wake both of them. Relieved that they’re both safe, Theresa hands their divine keys back as she explains AE’s plan. Sirin’s real body was suspended in the air with Selene being able to weaken her link to her four gems, but couldn’t cancel Sirin’s Honkai energy. Thus, Einstein moves Arahato to extract the exposed gems, one by one, which begin to tear away at the mech. The first core they managed to extract is the Gem of Conquest, which would become the Herrscher of Thunder’s core, but before Einstein could get the other three that were exposed, Sirin wakes, having defeated Welt’s mental avatar in the dream world. Angry that one of her gems was taken, Sirin throws Arahato off the Tower, knocking Einstein into unconsciousness. Sirin then crushes the Core of Reason, discarding it as she hoped it would finally kill Welt off. That was when one of Judah’s spears lashed at her and one of Shamash’ bullets flew past her. Turning, Sirin is then trapped when Abyss Flower grew a plant around her as the three scions of the Three Houses approached her. Cursing Cecilia for having lied to her, and believing the other planned to kill her all the same, Sirin wills both Siegfried and Cecilia into her Infinity Corridor, leaving Theresa to face her alone. 
Steadfast and determined, Theresa readies Judah’s 0th power which quickly nullifies Sirin’s powers. Without her herrscher form, Sirin returns to wearing patient clothes as she’s finally vulnerable on the field. Theresa then staggers over to her, being affected by the field as well due to her Vishnu Honkai genes, and apologizes, driving her spear through Sirin's heart. However, Sirin still had her gems, and as soon as Theresa turned down Judah’s 0th and pulled her spear away, the Gem of Serenity restored Sirin’s heart. In the meantime, Siegfried is trying to find a way to leave the Infinity Corridor, ending up with shooting the floor of the realm. The bullet circumvents back around Siegfried and misses him by an inch. Confused by the spatial properties of the Corridor, Kevin then appears to ease his qualms. Kevin explains to Siegfried that he wasn’t physically present but because Siegfried’s genetic memory had been activated, he was able to converse with Siegfried through quantum entanglement. In order to help him escape, Kevin gives Siegfried a hint about quantum tunnels. Quantum tunnels would emerge when Siegfried strikes a single point, allowing his next attack to exit the Corridor. Before he does this, Siegfried takes another activator for his ichor. This allowed him to deal a blow that set the box that contained his Infinity Corridor on fire, which was inside Sirin. In a panic, Sirin stops finishing Theresa off as she throws the box out of her. The box breaks as Siegfried is overcome with an overwhelming thirst for vengeance against the Honkai, going berserk as his dormant Honkai genes are expressed again. 
Facing the berserker, Sirin attempts to put distance between her and Siegfried, but the Kaslana makes these attempts futile, activating Shamash six times in the span of 3 minutes. With Sirin fleeing, Theresa could only watch in wonder at how Siegfried’s able to keep up with the herrscher before Einstein arrives, explaining the ICHOR situation as she escorts Theresa to safety. Welt, though without a physical form, is still inside the Reason core and managed to heal Einstein before taking over Arahato’s systems. At HQ, Amber is stunned at the overwhelming power coming off of Siegfried before Otto finally returns. He orders Amber to put the Rebirth program on hold and to send Fu Hua back to HQ once she’s done being treated. Looking at the footage of the berserk Siegfried, Otto only scoffs in disgust, remarking how Siegfired seemed less of a savior and more of a madman trying to get revenge on the Honkai. As for Sirin, she is fleeing through the woods with Siegfried on her tail. Shamash, though, soon runs out of Honkai reserves and Sirin turns to send Honkai beasts to finish Siegfried off. However, Siegfried only tears her legion apart and begins to eat them, replenishing Shamash’s Honkai reserves. He then leaps through the air, severing Sirin’s left arm before sweeping around her and throwing her into the ground below. Ripping the Gem of Serenity and Infinity Corridor holding Cecilia free, it is revealed that Kevin was the one giving Siegfried the genetic suggestions that made him bloodthirsty for the Honkai. However, Kevin is surprised that Siegfried is able to retain a bit of his sanity when the latter seized the Infinity Corridor, remembering Cecilia. Meanwhile, Sirin finally realizes she’s dying and in her despair over her solitude, her core cascades, easily growing to the same magnitude of the eruption that had swept over Siberia earlier. HQ is quickly notified of this, with Amber informing Otto that a new batch of Honkai fission weapons are ready. Otto, though, only dismisses the arsenal, saying that he’ll leave the battlefield’s countries to handle themselves. 
In a village not far from the Siberian plain, Natasha Ciora, who will later be known as Raven, and her brother notices the cascade and are soon both infected. Meanwhile, the core’s eruption had knocked Siegfried out, with Cecilia trying to treat his multiple fractures and muscle tears from his berserker activity. Kevin watches from afar, surprised that the Current Era had already managed to train someone to wield Abyss Flower, but also noting that both Siegfried and Cecilia were out of time. He projects that the cascade will soon engulf over half of Asia and sighs at Cecilia and Siegfried’s weakened states, claiming that the to-be disaster would be unsalvageable before leaving. With his departure, Siegfried wakes and tries to get Cecilia to save herself, and she surely objects. When large Honkai spikes from the cascade descend on them, it is Arahato that shields them, as commanded by Welt. Welt sacrifices the mecha but not before commanding it to generate a shield for Cecilia and Siegfried using the Selene engine. The fractured Reason core then falls through the shield next to Siegfried, allowing him and Welt to chat. Welt explains to Siegfried that he managed to get both him and Cecilia some time with the shield, advising him to use this final shot at stopping the disaster. After being healed by Abyss Flower, Siegfried then tells Cecilia that Sirin’s cascade can be stopped with a fully powered Shamash, but first they needed to find Sirin’s core amongst the sea of Honkai energy. In order to save the rising potential casualties, Cecilia willingly chooses to drain her body of her holy blood, which was a temporary Honkai neutralizing agent, after telling Siegfried she had a way to clear the Honkai and give him a shot. With the Honkai cleared, Siegfried uses the Reason Core to charge Shamash up to 100% before unleashing the Might of An-Utu on the core, exceeding 300% of Shamash’s recorded max output - and ending the cascade.
With the Honkai in the area gone, Schicksal’s satellites are back online, reporting Siegfried’s and Sirin’s location. Amber suggests sending in a rescue team but Otto quickly seizes control, ordering Amber to lock down all intel and commlinks about the event as he plans to tell history that Schicksal dealt the killing blow. Otto refused to let Siegfried live after seeing how much power he had wielded and ordered the launch of Honkai fission missiles he had received earlier. Meanwhile, Siegfried wakes on Cecilia’s lap as the other apologizes for not being able to return with him. Cecilia asks him to take care of their Kiana well before leaving Siegfried in the shelter of Abyss Flower’s new tree. Cecilia is aware that Otto has launched the missiles and uses her already limited time to find Sirin. Catching Sirin’s body as it fell towards the ground, Cecilia explains to Sirin why she had played along with the dream world. Cecilia had felt Sirin’s misery and loneliness and thus had wanted to reach out and comfort her. She had genuinely wanted to be the mother that Sirin never had in order to make it all up to her, but couldn’t do as much in the limited time they had in the dream world. Hence why she now held Sirin in their final moments, in order to share one last moment of warmth together, telling her those three magic words again: ich liebe dich. 
=== Aftermath===
The cascade zone had spread to infect at least 100,000 nearby civilians. However, blood-red lilies had then fell from the sky, neutralizing the radiation in anyone it touched, leading to less than 3000 people dying. Humanity then came to know the past events as the 2nd Honkai War. Theresa soon woke up at HQ with Amber telling her the fabricated truth of the war, with Otto manipulating her mind. Theresa came to believe that Schicksal fought in the war alone, without Anti-Entropy, and that Cecilia asked them to launch the missiles. Meanwhile, Siegfried returns Welt’s core to Anti-Entropy, saying that Welt’s presence still remains in the core. Einstein agrees and says that AE will do everything they can to bring him back before offering Siegfried a place at Anti-Entropy. Siegfried politely turns her down, saying that he had no choice as Kiana was still in Otto’s hands. Otto, meanwhile, had analyzed Kiana’s DNA to see if he could find the gene sequence that was expressed by Siegfried’s ICHOR, but failed to find it. Amber then reports that they had secured the Gem of Serenity, Haste, and Desire as well as the Core of Void and Sirin’s body. Amber also adds that Hua had wandered off before any of them knew but Otto says it’s fine. Hua arrives at the home that Lixue had been raised in, surveying the empty scene. With a solemn expression, she then leaves while Otto claims that she will return later as she has nowhere else to go. Several years later, Otto is making the K Series clones, and with the recent failure of K422, he plants Sirin’s core into K423, hoping she would gain awareness. Meanwhile, Sirin dreams of Cecilia, missing the other as she wishes for another chance at life so perhaps she could hear Cecilia say those words three words again. With her wish, K423 gains awareness and wakes.
