Daigo Seko/Synopsis

## Plot

### Yurina Appears

As Daigo prepares breakfast for himself and his sister, Nonoka Seko, the two are visited by his childhood friend, Ea Yuki. Later, as Daigo and Ea walk to school, Ea asks him to play a new smart phone game she is playing called Encircled Grimzelia. Daigo dismisses the game, saying he will get no satisfaction from it, and inadvertently huts Ea's feelings. Later that night, feeling guilty about Ea, Daigo decides to try the game. After Nonoka barges in on him, Daigo starts the game's quest mode and bright flash of light erupts from the phone. Before Daigo and his sister appears Yurina, the game's mascot.

   After some initial confusion, Daigo tries to determine how Yurina came to life. He decides to go over to Ea's house to see if she knows anything. Surprisingly, Ea grabs Daigo, taking him alone into her house and then tries to seduce him. After throwing Daigo across the room, Ea vomits a strange substance that morphs into a giant monster called Mad Golem. Daigo futilely attacks the monster, but is saved by Yurina who explains that it is a monster from Encircled Grimzelia. After Yurina is injured and captured by the monster, Daigo attempts to summon a weapon for Yurina to use, but hesitates due to the cost. Ultimately, Daigo pays to summon the weapon, but the sword they receive turns out to be useless. Daigo ends up having to draw ten more weapons, costing him even more money, but Yurina is able to defeat the Mad Golem after receiving an S Rare sword, thus saving themselves and Ea. Later, Daigo discusses the situation with Yurina and he agrees to let her stay at his house, knowing that are certainly more monsters out there that Yurina will have to defeat.

   Sometime later, Daigo posts an inquiry on the Grimzelia message board about how to level up fast without paying, but is met with rude responses, except for a high-ranked player named Eternal Wind. The next day, Daigo discuss how they will proceed with making Yurina so she can defeat the "Boss" of the real world. Daigo decides to put Yurina through physical training, but it seemingly proves to be fruitless as she does not gain a level. Daigo then gives Yurina another sword, but, believing it to be just another common Villagers Sword, Yurina is hurt and runs off. Daigo eventually pursues Yurina and finds her in combat with the Hades Bee monster. Daigo then reveals that the sword he gave Yurina is actually an enhanced version of the Villagers Sword that possesses a special Skill, which he then activates allowing Yurina to do massive damage to the monster. However, Daigo ends up having to pay more money to cure Yurina's poison affliction before they can defeat the monster. Daigo and Yurina reconcile and head back home.

Wishing to pay Daigo back for the money he has spent, Yurina informs Daigo that she will get a job, but he objects and dismisses the issue, pointing out that she has no real world skills and will not fit in with any typical job. Later, Daigo finds Yurina working a Grimzelia-themed cafe as a waitress, which he is initially opposed, but relents on the condition he decides what to do with her salary. When Danzum, the obnoxious son of the Grizel Cafe owner, shows up and insults Yurina, Daigo tries to defend her, but she ends up inadvertently pouring ketchup on Danzum's after running out of AP, which results in her getting fired. With Yurina saddened by her failure to keep her job and for assaulting a human, Daigo cheers her up by giving her a pair of earrings that will allow her level up her Skill points faster. The next day, Daigo receives a call from the Grizel Cafe manager who offers to rehire Yurina.

### Ea Joins

Daigo is later visited by Ea who accidentally discovers Yurina after barging in on her as she is trying to use the bathroom. After an awkward moment, Daigo and Yurina explain the situation to Ea who becomes captivated by Yurina's existence. During the ensuing conversation, Ea reveals she is at a much higher level than Daigo in Grimzelia, which prompts Yurina to beg Daigo for more S Rare weapons, but he refuses. Daigo then leaves for work, but Yurina and Ea follow him there as they try to think of ways to draw more weapons for Yurina. After a disastrous attempt to use Yurina as Ea's friend support, which ends in her destroying a portion of Daigo's shop, Ea inadvertently summons another monster; the Poison Nepenthes. After the monster grabs Ea, Daigo attempts to equip Yurina with an S Rare weapon, but is unable to do so as he has exceeded his monthly credit limit and cannot add funds with a gift card since the register is broken. Regardless, Yurina manages to free Ea, but is swallowed by the monster as a result. Daigo and Ea then attempt to summon Ea's Yurina as a friend support, but, to their surprise, Ea herself transforms, donning the S Rare gear from the game. After Ea too is swallowed too by the Nepenthes, Daigo futilely attacks it with a broom, but Ea manages to free herself and Yurina by destroying the monster from within. Afterwards, the trio clean up Daigo's store and Ea reveals that she has never spent money on Grimzelia and apparently just gets S Rare weapons through sheer luck. Daigo comes to an agreement with Yurina that they will not lose to Ea.

### Eternal Wind Joins

With Ea now part of Daigo and Yurina's group, the three of them, along with Nonoka, go to the park to battle more Grimzelia monsters. Ea summons a ghost monster for Yurina, but she ends up getting caught by the monster forcing Daigo to 10x Draw an S Rare staff for Yurina. After the battle, Yurina's S Rare weapon breaks once again and the group discusses the possibility of recruiting more Grimzelia players to help them fight the monsters, the most notable among which is the high-ranked player Eternal Wind. The next day at school, Daigo and Ea discuss the situation, but their phones are apprehended by the class president, Haruka Nanao. Daigo asks for his phone back, but is met with hostility by Haruka and her friends, although his Villagers Sword +10 almost causes Haruka to reveal that she is an avid Grimzelia player.

A few days later, Daigo and Ea have still been unable to recruit a friend due to Haruka continuing to take their phones away. Daigo explains to Yurina that Haruka is their class president who has always been strict since she was a child. Later that evening, Daigo goes out with Yurina and Ea to fight more Grimzelia monsters. The trio summon the monster Absorber and fight it while, unbeknownst to them, Haruka observes them. During the battle, Ea is grabbed by the monster, but manages to defeat it, causing Daigo to berate her for being so risky. The group are then approached by a girl in a one-piece swimsuit who turns out to be possessed by a Grimzelia monster; the Mecha Scorpio. Daigo tries to summon Ea as a friend support again, but she explains that he can only summon her once per day. As the monster attacks Yurina, Daigo and Ea try everything they can think of to power her up, but are seemingly left with no options. Just then, Daigo receives a friend request from Eternal Wind and, though he is initially reluctant to do so, he summons her. Eternal Wind suddenly appears and Daigo, not recognizing her as Haruka, apologizes for summoning her, but nonetheless asks her to help. Eternal Wind easily defeats the monster and, after checking on Yurina, Daigo thanks her for saving them.

The next day at school, Daigo meets with Ea to discuss the current status with Eternal Wind and Grimzelia, but is interrupted by Rikoha who sees that he is now friends with Eternal Wind. After Rikoha makes disparaging comments about Yukyu, Daigo expresses his own admiration for her in that she has been able to amass such a large amount of trust. His praise flusters Haruka (whom Daigo is still unaware is Eternal Wind) and she awkwardly admonishes him before running off, much to Daigo's confusion.

### Yurina's Despair and Daigo's Transformation

   With Eternal Wind part of their group, Daigo talks with her through e-mail and gains valuable information about Grimzelia from her. However, Yurina complains, saying they shouldn't rely on her so much and, although Daigo remains unenthusiastic, he ultimately relents and agrees to train Yurina some more. The two meet up with Ea and summon a new monster; the Muscargot. Though expected to be an easy victory, the monster gets the better of them and sprays digestive juices on Ea, attempting to devour her. In a panic, Daigo summons Eternal Wind despite Yurina's objections, while also harshly stating that she would be no good in the fight. Eternal Wind arrives and apparently defeats the monster, though Daigo is forced to apologize for summoning her to defeat such a weak monster. As they begin to head home, Ea says her stomach feels heavy, but Daigo and the others dismiss it as her just needing rest. Daigo heads home with Yurina while harshly commenting that it's hard to tell who the hero is. Early the next morning, Daigo is visited by Eternal Wind who complains that her costume still has not vanished. Daigo looks at his Grimzelia app and finds that Yurina is curled up in her bed and down to zero AP. He rushes to Yurina's and finds that has, indeed, curled up in her bed and grown completely despondent, believing she is not worthy of being a hero. Daigo tries to reassure her, but his and Eternal Wind's efforts prove fruitless. Suddenly, Ea appears at the window, possessed by the Muscargot, which is actually a slug. Daigo checks his app and sees that Ea has been afflicted with Parasite status, meaning the monster is draining her HP. After the slug detaches from Ea, making her fall unconscious, Daigo tends to her, but Eternal Wind has difficulty against the slug as her attacks only cause it to multiply. Daigo tries to help, but can do nothing as the slugs overwhelm Eternal Wind. Daigo then goes to Yurina and gives her a reassuring pep talk, explaining that she is a true hero as she has a strong desire to help others. His speech reinvigorates Yurina, but she still has trouble against the slugs. After receiving a suggestion from the now-conscious Ea, Daigo pulls out a second smart phone and uses it to friend summon. Surprisingly, the summon not only changes his outfit, but also his gender, making him female. Though embarrassed, Daigo uses his weapon, the Phantom Rare staff Apocalypse, and allows Yurina to defeat the slugs in one swipe. Afterwards, the Wi-Fi connection on Daigo's phone is disrupted, causing him to change back to male, but still adorn the Grimzelia gear, much to the embarrassment of everyone in the room.

Later, Daigo attends a Skype meeting in which he and Ea suggest telling the Grimzelia developers about the monsters, but Eternal Wind advises against. Daigo and Ea overhear Eternal's cat and she informs them its name is Storm, which impresses Daigo. Later that day, Daigo goes to pick up Yurina from her job and learns that she received her first pay. Daigo tells her he won't let her spend it on Grimzela, but Yurina informs him she has already decided to save her money. Pleasantly surprised, Daigo reminds Yurina about their date with Ea, prompting Yurina to return to her job to ask for the day off.

### The Snow Girl

    While preparing for their trip to the mall, Daigo attempts to get Yurina a new S Rare gear, taking advantage of a bonus special that makes drops four times more likely (though he ends up having to draw 19 times anyway). He ends up getting her a strawberry-themed gear, allowing her to blend in. Yurina offers to pay for it, but he tells her to consider it a gift. Daigo, along with Yurina and Ea, head to a game center, where Ea tries to win a giant stuffed Yurina doll. Daigo suggests simply buying one and then selling the doll once they win it, much to Ea's chagrin. After having some fun and making a purchase at a Zakka store, Daigo and the others go to an ice cream parlor that is offering a special ice cream for "hot guys". After Ea volunteers him for the offer, Daigo is taken into the back where he is frozen solid. He is soon discovered by Haruka, Yurina, and Ea who then do battle with the Snow-Men and Yuki-Onna who froze him. Yurina and Ea are frozen by Yuki-Onna as well, leaving Eternal Wind to fight her alone. However, Daigo is mysteriously thawed out during the battle and dons his Apocalypse gear. He powers up Eternal Wind, saving Yurina and Ea and defeating Yuki-Onna. Afterwards, Daigo and the others, still unaware that Haruka is Eternal Wind, meet up with her and explain that they are heroes due to the Grimzelia game. After Haruka inquires about it, they also explain that they went to the mall without Eternal Wind because they wanted to buy some surprise gifts for her.

### A Trip to the Beach

With the summer season upon them, Ea suggests to Daigo and Haruka that they take a trip to the beach. However, Daigo and Haruka are exhausted from staying up late, trying to get a special gear from an S Rare event. Also, Daigo is concerned that there has been no reaction from the general public about the boys abducted at the ice cream shop. After Ea explains she actually has a plan to track down Grimzelia monsters by looking for girls in school swimsuits, Daigo agrees to the idea, with Haruka, Rikoha, and Ami deciding to tag along as well.

At the beach, while the other girls have fun, Daigo tries to console Yurina who is unable to go into the ocean since she doesn't have any swimsuit gear. Yurina asks Daigo to draw a swimsuit gear for her, but he refuses saying he will only do so to increase her power. The two are then met by Rikoha and Ami, the latter of whom is wearing a one piece school swimsuit. The four are then interrupted by Ea who informs them that Haruka has collapsed. Daigo and the others tend to Haruka, trying to cool her off, while Nonoka goes to fetch a lifeguard. When Ami begins to draw a picture of the unconscious Haruka, apparently delighting in her suffering, Daigo confronts her and accuses Ami of being a Grimzelia monster due to her behavior and her school swimsuit. However, Ea and Rikoha explain that Ami always wears her school swimsuit and that she has a fetish for seeing girls suffer, which Ami confirms. Yurina comments to Daigo that she feels like she's seen Ami before, but they brush it aside and begin to look for other girls in school swimsuits.

After traversing the beach for some time, Daigo, Yurina, and Ea encounter three small girls in school swimsuits on top of a large rock. The three girls jump into the water and, when they do not emerge, Yurina dives in to save them, but is dragged under the water. Daigo follows after her and finds she is in the grasp of three Grimzelia monsters who had been possessing the girls' bodies. Daigo goes back up for air, informing Ea of the situation, but he is dragged back down, unable to fight as he left is phone behind. As Daigo begins to pass out from lack of air, he suddenly awakens back on the beach with Ea and transformed into his female self. Ea explains that she friend-summoned Daigo using his sub-account and equipped him with swimsuit gear, after which Daigo rushes back into the ocean to help Yurina.

    As Daigo engages the monsters in battle, Ea and Eternal Wind arrive, distracting two of the monsters, leaving Daigo to fight the remaining octopus monster. Daigo struggles against the monster, but, amidst the chaos, Ea returns his main and sub-account phones (both in plastic bags) to him. Just as Daigo's oxygen level is about to deplete, he activates his Coral Slash skill, destroying the monster. Daigo tries to bring Yurina back up for air, but is dragged back down by Lolivia, the leader of the monsters. As Lolivia drains his oxygen, Daigo's phone notifies him that he has exceeded his data limit and he reverts to his male form. Lolivia subsequently discovers his true gender and is impressed by the size of his genitals, declaring him the Second Demon King. Lolivia then drags Daigo and Yurina off to take them to Lamia, but, knowing that Yurina is almost out of breath, uses the air his phone's plastic bag to give her some air. When the plan fails, he simply uses his phone to pay for extra oxygen for Yurina. As Yurina battles Lolivia, Daigo performs a 10x Draw, drawing her an Aqua Compressor gear, which she uses to apparently defeat Lolivia. Daigo faints from oxygen deprivation, but Yurina brings him back to the surface.

Afterwards, Daigo apologizes to Ea for destroying her phone, but Yurina asks to have it as keepsake. After Yurina runs off to play with Nonoka and Rikoha, Daigo comments to Haruka that the S Rare they used didn't break as the others had.

### The Festival

After their adventure at the beach, Daigo, Yurina and the others arrive at Ea's vacation home. While all the girls except Haruka take a bath, Daigo and Haruka prepare a meal in the kitchen. When Haruka asks Daigo about the S Rare weapons that have broken, he brings up the Chaos Blade, but Haruka remarks that no such weapon exists in Grimzelia. Ea and others barge in and are impressed by the food, though Rikoha wonders why they can't just buy food at the festival, to which Daigo replies that the food stands are rip-off. Later, after Rikoha and the other girls decide to wear yukatas to the festival, Daigo equips Yurina with a Candy Apple S Rare gear so she can wear one as well. However, unbeknownst to Daigo, her attention towards Yurina begins to make Ea jealous.

Later, at the festival, Daigo shows Yurina how to play a goldfish-catching game. When Ea tries to join in, Daigo stops her, saying she is too clumsy. Daigo is then kicked by Nonoka who explains that he needs to better about dividing his attention between Yurina and Ea. After Rikoha, Haruka, Ami, and Nonoka take their leave, Yurina happens upon a lottery stand, but Daigo warns her that it is a total scam. Nevertheless, Yurina attempts the draw, but, sure enough, she only wins a meager party horn as a consolation prize. Ea then attempts the lottery and wins first prize, but Daigo is still too distracted by Yurina to notice her. Ea then tries a rifle-shooting game, but when she is unable to hit the target, Daigo appears and gets the prize on the first shot. He gives the prize to Ea and explains that, while it would be a waste for her to try the shooting game, it's fine if he does it himself since he can get it on the first shot and, thus, it is not a waste of money.

Meanwhile, Yurina, who feels left out due to Daigo paying attention to Ea, is approached by the Chief from the Grizel Cafe. After luring Yurina away from the festival, the Chief reveals herself to be a Grimzelia monster called Venomous Moon Jelly and attacks and poisons Yurina. Seeing her poison status on his phone, Daigo, alongside Ea, rushes to her aid. However, Daigo finds he cannot make any friend summons since he has already reached his limit for the day. Venomous Moon Jelly attempts to finish off Yurina, but Ea blocks the attack by summoning another monster from her phone. However, Ea subsequently summons more monsters to block the attacks of the other monsters and the group is soon surrounded. After Yurina and Ea get into a bitter argument about each other's usefulness, Yurina that she will defeat the monsters herself and only needs Daigo to perform four single draws to do it. Daigo is i ncredulous, but nevertheless goes along with Yurina's plan. He summons four Villager's Swords and Yurina tells him to fuse all their extra Villager's Swords together as they now have 50 of them. Daigo does so and Yurina is equipped with the S Rare gear Corona Blade. Yurina quickly dispatches two of the monsters, but Venomous Moon Jelly gets away after threatening to kill its host body.

With the battle over, Haruka and Ami arrive, but the latter states that Yurina cannot be counted on, much to Daigo and Yurina's confusion. Ami then tells them they need to talk at the Grizel Cafe.

### Ea's Abduction

    After the festival, Daigo returns home with Yurina, Ea, and Nonoka, but Ea is still feeling quite bitter towards Yurina. As Yurina expresses her gratitude towards Daigo, which he happily accepts, Ea belittles and demeans her, confounding Daigo as he is caught in the middle. After Yurina and Ea have a heart-to-heart talk and Ea takes her leave, Daigo expresses his desire to not involve Ea in the dangerous Grimzelia battles anymore. Yurina then abruptly asks him if he is in love with Ea. Daigo is flustered, but admits that he does love Ea.
Later that night, Daigo, Yurina, and Ea walk to the Grizel Cafe to keep their meeting with Ami. However, they are met by a woman in a business suit who reveals herself to be a Grimzelia monster named Lamia and proceeds to swallow and capture Ea. Daigo protests, but Lamia ignores him, intending to leave with Ea in tow. However, Yurina stops Lamia and begins to battle her. Daigo activates Yurina's Thousand Maple Villager's skill, but, not only does it not damage Lamia, but Yurina loses her Villager's Corona Blade due to Lamia eating some of the swords that made up the blade. After Daigo attempts to friend summon Ea, to no avail, Yurina is pierced and swallowed by Lamia, though she hints to Daigo that this is part of her plan. Daigo stands by with herbs to heal Yurina, but quickly finds that Yurina's HP is depleting rapidly as Lamia is rapidly digesting her. Luckily, Eternal Wind arrives in time to save Yurina and Daigo tends to her. Unfortunately, even Eternal Wind is no match for Lamia and she is seemingly killed by the monster, much to Daigo and Yurina's shock. Daigo and Yurina pathetically attempt to stop Lamia one last time, but she easily swats them aside, leaving with Ea.

    Afterwards Ami suddenly appears along with the manager of the Grizel Cafe, who reveals herself to be Riho Utsugi, a former developer of the Grimzelia app. Furiously, Daigo demands an explanation from Riho for why the Grimzelia monsters are coming to life, but Riho is unable to as she has no memory from her time developing the Grimzelia app. Ami proposes that the four of them work together to rescue Ea, but Daigo initially refuses, claiming he cannot trust Ami. However, after some coaxing from Ami and Yurina, he relents and agrees to work with them. Daigo then hears a strange noise and discovers Haruka sobbing over her computer tablet. Not realizing that Haruka has lost her Grimzelia account, Daigo and the others decide to leave Haruka alone as she will not tell them what's wrong. However, Haruka offers to help save Ea after learning she has been kidnapped. Daigo accepts her help, though he is somewhat reluctant due to Haruka's perceived inexperience. He then declares that they will save Ea.

Later at the Grizel Cafe, Daigo and Yurina are shown Ami and Riho's secret underground bunker where they have been planning their attack against the Grimzelia monsters. The four discuss their predicament with Daigo voicing his concerns about Haruka's inexperience and their inability to locate Ea. After Riho informs that she has recruited several high-ranking Grimzelia players, a girl possessed by Fierce Lord Nametake walks into the cafe and attacks. Though Ami and Riho try to fight the monster, they are ultimately too inexperienced to prevail and Yurina is forced to step in and save them, which Daigo chastises them for afterwards. Daigo and Yurina later meet the high-level Grimzelia Rankers that Riho has recruited to help them.

### The Rankers

After getting some time to know the Rankers, Daigo and the others discuss their plan of action. While Ami infiltrates the enemy base, the others will train and get stronger, though many of the Rankers seem reluctant. Later, during a training session, Daigo and Yurina go to a train station to track down a monster, but only Honoka agrees to join them. They meet up with Honoka, but she proves to be very peculiar as she has a compulsive need to disinfect everything. Honoka is also very sickly, which gives Daigo and Yurina reservations about recruiting her to fight alongside them. The three then follow a girl that they believe to be possessed by a monster. Their assumption proves correct and Yurina swiftly defeats the monster. Afterwards, Honoka suggests that they can power up Yurina's Corona Blade by powering up each individual Villager's Sword, but Daigo is resistant to the idea due to how expensive it would be.

After Honoka collapses and rests on a park bench, Daigo and Yurina tell her that they cannot accept her help due to her physical weakness. Yurina is then suddenly attacked by the Moth Lady monster and struggles against her even with her Corona Blade. Daigo attempts to flee with Honoka at Yurina's command, but Honoka convinces Daigo to friend summon her. Honoka saves Yurina and defeats the monster, thus convincing Daigo and Yurina that she is a capable fighter.

Some time later, after Daigo expresses his frustration that the other Rankers haven't been participating in the training sessions, Daigo, Yurina and Honoka go to Marimo's house. Outside her house, Daigo and the others encounter Rin Mei, Marimo's assistant, and Daigo is accosted by Marimo while she is in her "Girl's Magazine Mode". After Daigo makes a derisive comment about Marimo's breast size, Daigo and the others agree to help with Marimo's manga manuscripts. However, one of Marimo's assistants is revealed to be possessed by a sludge monster, which attacks. Yurina is unable to fight, however, as working on the manuscripts has drained all of her AP. Daigo friend summons Marimo and Rin Mei and they are able to defeat the monster and rescue Yurina. Afterwards, Marimo and Rin Mei agree to help Daigo and the others full time.

Daigo, Yurina, and Marimo later decide to go to Karasu's house, but Daigo is anxious about having to tell Karasu that friend summoning will give him the body of a girl. Unfortunately, their meeting goes poorly as Karasu refuses to participate in training and expresses his disdain for the Grimzelia app. Daigo and the others leave, but are then attacked by the monster Ghoulganger, who incapacitates Yurina and Marimo. Fortunately, Karasu arrives and Daigo friend summons him. Although Karasu is able to defeat the monster, Daigo is very surprised that Karasu has no reaction to being turned into a girl. After grabbing Karasu's "fake" breasts, Daigo and the others come to realization that Karasu is, in fact, a girl. Additionally, Karasu has been looking after her younger siblings after their parents, who worked on Grimzelia, went missing. The day concludes peacably with Daigo and the others enjoying a dinner with Karasu and her siblings.

    Later, at the Grizel Cafe, Daigo and the others discuss Haruka's situation as she has still not been able to obtain a powerful weapon on Grimzelia. Ultimately, this results in Daigo being asked to draw a weapon for Haruka in the hopes that he will draw a Villager's Corona Blade for her like Yurina. Daigo is overwhelmed by the pressure, but ends up drawing Agateram, a very powerful weapon. Haruka tests out her new weapon on the Mechanical Death Bee monster, despite Daigo and the others doubting her capabilities due to her perceived lack of experience. However, Haruka ultimately prevails agains the monster, convincing Daigo and the others that she is capable. After several more training sessions, Daigo and others receive word from Riho that Ami has located Ea and thus the invasion of Lamia's base can begin.

### Rescuing Ea

On the day of the invasion, Daigo rides the train with everyone else and they prepare for the upcoming battle. Daigo and the others encounter some initial difficulty as his phone does not receive reception entering Lamia's base, but he gives his phone to Rikoha so she can manage everyone's weapons and items from a distance. They then enter the base, but are quickly caught offguard by Nightshade and fall through a trap door. Daigo awakens to find only Rieco at his side in an empty room. He deduces that the trap door must have separated everyone and the two go to look for the others.

After fighing off some low-level monsters, Daigo and Rieco encounter and battle Princess Titan. The two have difficulty against the monster as Rieco's weapon does not seem to work and Rieco admits she has no idea how to play Grimzelia and was only playing for a friend. Regardless, Daigo puts his faith in Rieco and deduces how her weapon works. Working together, the two are able to overcome Princess Titan, after which Rieco reveals to Daigo that her real name is Saori Kashiwagi. However, Princess Titan recovers and grabs Daigo, but he reverts to his male body while in her grasp. Princess Titan then bows to him and addresses him as the Second Demon King. Daigo is confused and Princess Titan explains that she and the other Grimzelia monsters wish to mate with him to procreate the next generation of monsters. Daigo is repulsed by the idea and Princess Titan alludes to the "Beta Version" of Grimzelia. Daigo then changes back to his female body and, while she will not give him any information while in his female form, Princess Titan agrees to accompany them.

Later, Daigo and Saori, having separated from Princess Titan due to her fervent desire to mate with Daigo, find Haruka who is fighting against Puppeteer. Believing that Haruka is having difficulty against the monster, Daigo expresses his guilt for not being able to protect her. Daigo and Saori try to assist but are incapacitated by Puppeteer themselves. Fortunately, Haruka prevails and defeats the monster. With the battle over, Daigo once more apologizes for not protecting Haruka and the two have a tender moment (prompting Saori to wonder aloud if there is a romantic connection between them, whcih they embarrasedly deny). Daigo then departs alongside Haruka and Saori as they wish to evade Princess Titan who is still pursuing them.

Some time later, Daigo, Haruka, and Saoir reunite with Yurina, Ami, and Riho and they discuss their current predicament and plan of action. After battling some low-level monsters, Daigo and the others finally locate Ea who is unconscious and strapped to a chair in an empty room. Venomous Moon Jelly appears and explains that she has poisoned and will fall asleep forever unless they give her the antidote. Venomous Moon Jelly attacks with a black ooze that incapacitates nearly everyone and pentrates Yurina's brain, bringing out all her resentment and jealousy towards Ea, turning her into "Dark Yurina". Yurina attacks the others, but regains her senses long enough to admit her feelings for Daigo. Left with no other option, Daigo attempts to delete his account to spare Yurina from being corrupted. However, Yurina quickly comes back to life, equipped with the Villager's Excalibur and defeats Venomous Moon Jelly. The group is then met by Lamia who brushes them off as they are not yet ready to face her.

After curing Ea, Daigo happily reunties with her and then has an awkward moment with Yurina as the two have developed feelings for each other. The group then battle Medusa who has already petrified Marimo, Honoka, RIn Mei, and Karasu. Yurina defeats Medusa, but the group are then attacked by a woman in grim reaper garb. The grim reaper woman then injects a fluid into Medusa, turning into a mindless monster that petrifies Saori and Haruka. The woman is then revealed to be human; the Grimzelia designer Yamada Rinko. After the Medusa monster petrifies Ami and Riho, Mayu and several other monster girls appear and explain that Daigo is the Second Demon King. After the monster girls forcibly revert Daigo to his male form, they use Yurina and Ea to arouse Daigo and awaken his Demon King powers. Daigo transforms and uses his new powers to defeat Yamada.

### The Final Battle

Afterwards, Daigo loses his power and reverts to his normal form. Medusa also reverts and Ea uses a special drop item to depetrify everyone. Lamia then appears alongside the other monster girls and they make clear their intention to mate with Daigo to create a new generation of monsters, which Daigo fervently opposes. Although Yurina and others do all they can to fight off the monsters, Daigo is ultimately captured and, to everyone's surprise, is devoured by Lamia.

 Daigo is absorbed into Lamia's body and she transforms, after which she begins to inject eggs into the bodies of the Rankers so she can create a new generation of monster. However, she is unable to inject eggs into Yurina, Ea, and Haruka due to Daigo's lingering will. Daigo is soon rescued by the Rankers who invade Lamia's body and find him inside a large void, in the grasp of a crystal statue of a princess. Daigo is released from Lamia's body, though the Rankers remain trapped inside. Also, Lamia has kept Daigo's male essence and he is stuck in his female form. And since Daigo's will no longer affects her, Lamia is free to inject her eggs into Yurina, Ea, and Haruka. Neverthlees, Daigo and the others continue to fight Lamia and are able to recruit Rebecca to fight with them. Unfortunately, Rebecca is also devoured by Lamia who then changes into an even stronger form.

 Daigo and the others are immediately overwhelmed by Lamia's new power, but, after using a special ticket provided by one of Lamia's former comrades, Haruka reobtains the Brionac, finally revealing her identity to Daigo and the others as Eternal Wind. Daigo and the others are overjoyed that Eternal Wind is still alive and Haruka quickly enacts her ploy. Using Brionac's Hollow Wind skill, she allows herself to be continuously swallowed by Lamia, preventing her from consuming anyone else. Although Haruka's gambit is successful, Yurina begins to despair, but Daigo encourages her and discovers an unknown weapon in his inventory. He equips it on Yurina and it is revealed to be the Ultra Rare Chaos Calibur, which Yurina uses to defeat Lamia in one blow.

 Daigo rejoins the others as everyone Lamia absorbed is released and all the monster girls retrun to the world of Grimzelia. Consequently, Yurina also apparently returns to the world of Grimzelia, her mission having been completed, and she gives Daigo a tearful farewell before disappearing.

Three days later, Daigo, Ea, and Haruka discover Yurina hiding in Daigo's closet. Apparently, since she considers Daigo's house to be her "home" now, she is free to live in the human world. Daigo happily agrees to treat her to a nice meal as she has not eaten in the those three days.
