Sons of Chaos: Seekers

Sons of Chaos: Seekers, known in Japanese as Sons of Chaos:Seekers, and Chinese as , is the fourth chapter of Digimon Seekers. It is split into twelve parts.
==Chapter 4-1==
The Sons of Chaos' plan had worked, every member of the and every Digimon in the Wall Slums were now on their side. The Gatekeeper Digimon and SoC's allied Digimon fight, the Gatekeeper's trying to prevent them gaining access to the . 
, Mindlinked with Kosuke Kisakata and having digivolved from , remains in the nearby — with the duo watching the battle from their vantage point. As they watch, they are ambushed by . Dorugoramon survives, to the shock of the Mindlinked Shuu Yulin, with the former comrades having back and forth banter. As the two Mega level Digimon fight, Ouryumon deflects one of Dorugoramon's attacks — with the attack carrying on, taking out a large amount of Gatekeeper and Crack Team Digimon. It continues even further still, and collides with the wall of the caldera — creating a hole in it. The hole was so big, it causes the wall to start crumbling.
Satsuki Tamahime, Mindlinked with her , had been watching the battle in the air on a , and watched on in awe at the clash between two Mega level Digimon. She loudly calls out for Yulin upon seeing Dorugoramon's attack, and, having already planned for this, had all the Cargodramon drop their passengers off into the battle. The DigiPolice were now in the battle and were not going to let the SoC achieve their plan. This is made harder, however, when the Gatekeepers assume the DigiPolice are also their enemies — leading to a three way battle. With no way to communicate to them that they were not their enemy, Satsuki had no choice but to order the DigiPolice to kill the Gatekeepers as well. Satsuki had wanted to take part in the battle against Dorugoramon but had been refused permission to do so by Yulin as was told she was not allowed to digivolve Numemon to the Ultimate level. She asks the recon if they had managed to find any of the SoC higher ups, though they relay that they had been unable to do so. As she tells them to keep looking, she is startled when jumps on top of the that Numemon had been riding. 
Satsuki, angrily recognizing Loogamon, yells out Eiji Nagasumi's name, with a Hololized Eiji surprised that someone knew his name. They quickly realize the voice belonged to Satsuki, and as such also realize that meant they had fallen into the laps of the DigiPolice. Eiji and Loogamon mock Satsuki, Numemon, and Mekanorimon, with this quickly leading to a battle. After Mekanorimon knocks Loogamon off itself, it and the aim their weapons and Loogmaon and Eiji. If Eiji were to be attacked in his Hololized form, he would die in real life, and as such he quickly switches from Hololize to Mindlink. They all fire at Loogamon, though it is able to avoid all of the bullets by diving behind a boulder for cover. This didn't last long though, as this gave the Cargodramon time to close in. Loogamon was now pinned down, stay behind the boulder and it'd be killed by the Cargodramon. Come out, and it'd be killed by the rest of the DigiPolice. Just as Satsuki was about to order the Commandramon to throw their DCD Bombs over the boulder, she is contacted again by the Sealsdramon — who tell her they had located their target. She demands their location with it telling her they were right above her head. Satsuki has no time to react, as — Mindlinked with Marvin Jackson — attacks the Cargodramon.

==Chapter 4-2==
/Marvin Jackson have just saved /Eiji Nagasumi, with Airdramon's attack on the allowing Loogamon to escape the line of fire. 
Satsuki Tamahime is surprised and questions the two of them as to why they would try to take on the DigiPolice on their own, whilst Eiji gets Marvin up to speed on what was happening and that Satsuki was a much bigger threat than when he had defeated her in the past. Needing to keep the rest of the DigiPolice away from Kosuke Kisakata and Shuu Yulin, Loogamon digivolves to and joins Airdramon in battle. They weren't alone for much longer however, with Marvin sending the other leaders of the SoC and a large group of into battle. A three way battle ensues, with the DigiPolice, SoC, and Gatekeeper Digimon all fighting each other. Wanting to defeat Eiji specifically, Satsuki calls in her "aces" and sends Tachibana and to attack Loogarmon. 
Eiji surveys the battlefield, spotting and fighting above them. He considered attacking Ouryumon to help out Kosuke, but decides against doing so upon remembering Kosuke had said he wanted to defeat Yulin on his own. As they pondered this, as well as if they should digivolve to the Ultimate level, they are attacked by camouflaged — with Eiji telling Loogarmon to use its Howling Burner in every direction so that they could flush out their enemy. This works, with the Commandramon coming out of camouflage to avoid the attack. Loogarmon, underestimating them due to them being Rookies, is taken by surprise when their attacks prove to be more powerful than a regular Commandramon's, and becomes even more shocked when they both digivolve to . Now in a two on one battle against two Mindlinked Champions, Loogarmon was at a disadvantage and began losing the fight. They had even managed to split Eiji away from Marvin and the other members of the SoC. Not wanting to have Satsuki reach Kosuke, alongside wanting to win so they could save Leon Alexander and , Eiji and Loogarmon's feelings synch together perfectly with Loogarmon beginning to digivolve. Kosuke, despite being in the middle of a battle with Yulin, yells out from above for the duo to achieve their ultimate forms — with this motivating Eiji and Loogamon and having them decide they were now actually ready to handle Ultimate level power. This motivation allows Loogarmon to digivolve to .

 has just digivolved to whilst fighting Tachibana and 's . The newly gained digivolution restores more of its memories, with Soloogarmon now having the upper hand against the DigiPolice's Digimon. It takes little damage from their attacks, and proceeds to defeat both of them with little effort. Eiji told Soloogarmon not to take it too far though, as he didn't want to kill the two DigiPolice members.
The light of the digivolution had been so bright, it put a stop to the fight between and . Shuu Yulin was surprised to see Eiji Nagasumi had achieved the Ultimate level, whilst Kosuke Kisakata celebrated the fact. Yulin would quickly snap out of it, reminding Kosuke that they were in the middle of a fight — to which Kosuke informs her he never intended to fight her in the first place and instead she was part of his plan. Demanding an explanation, he tells her that they now have three Prototype Digimon at the Ultimate level — with them being Vaccine, Data, and Virus Attributes. Having no clue where he was going with this, she asks what's he's plotting though he tells her he was not plotting anything and was moving onto the next phase of Operation Tartarus and he had not given up on Saya Ryusenji. She tries to comfort him over the loss of Saya, but he snaps at her and tells her she knows nothing about the current version of him. Realizing that Kosuke needed Ouryumon for his plan, she figures out that Kosuke was unable to win their current fight — to which he confirms. Yulin argues back that she will be the one to save Saya, not him, but he informs her that Operation Tartarus would save her and that was the one that had told him about it. He would go to depths of the depths of the and find the Sacred Chalice, which Dorumon claims will be able to save her. Despite the reveals, the fight continues but just as Ouryumon was primed to score the killing blow — Yulin hesitates, with Kosuke telling her she will not be able to kill him. Not because she's a cop, and as such would not want to kill someone, but because by killing him Saya would die too as he was the only one who would be able to save her. Since Ouryumon's killing blow failed, it became an easy win for Dorugoramon — who defeats Ouryumon with a counter attack.

 has just defeated , with Ouryumon de-digivolving to . Having won, Dorugoramon de-digivolves to and checks on Ryudamon to make sure it's still alive. Figuring he still needed to keep them out of his way, Kosuke Kisakata uses a program to restrain Ryudamon — just in case it were to awaken. With phase 2 of Operation Tartarus now complete, Kosuke declares it was now time to start phase 3. He contacts Marvin Jackson and asks if he's still alive, to which he confirms he is. He then learns about how the rest of the battle was going — the DigiPolice had around a third of its members left, whilst the only remaining members of the Sons of Chaos were Kosuke, Marvin, Eiji, and a few of the other leaders. Though some members of the and Wall Slum Digimon remained, there weren't enough of them for them to guarantee a win against both the DigiPolice and the Gatekeeper Digimon. Dorumon tells Marvin to bring Eiji to them, with Marvin asking if they were going to use "you know what". Upon hearing confirmation they would, Marvin activates a tool from his suit — with a loud roar being heard. 
Satsuki Tamahime, having seen easily defeat Tachibana and 's , angrily and confusingly questions the fact that Eiji Nagasumi was able to digivolve his partner to the Ultimate level. She had heard he had done so whilst fighting Leon Alexander, but also heard he had lost control of the Digimon and as such was confused why this wasn't the case right now. As she yelled out about this, one of the DigiPolice members tells her Shuu Yulin and Ouryumon had been defeated. Now in charge, with Yulin out of action, Satsuki tells the left flank to retreat and regroup with the remaining forces and the right flank to go center to take care of the attacking Gatekeepers. The remaining DigiPolice try to fight back against her commands, but she reminds them that as deputy leader — she was in charge upon times Yulin wasn't able to do so herself. She contacts Tachibana and Sakurada, tells them to retreat, and that she will take their place in the battle. They apologize for losing, though she tells them it wasn't their fault. Unable to reject their new orders, they — whilst still Mindlinked with their partners — escape the battle on the .
Satsuki looks around for Eiji, but is interrupted by the recon . It tells her that Kosuke had Hololized and was talking to the other members of the SoC. She tells it to keep an eye on them, but to retreat if things get too hot to handle. 
Marvin and Airdramon deliver Eiji and to Tartarus, then leave to return to the battlefield. The other SoC leaders with Kosuke log out, with all of them having things to do in the real World. Tartarus thanks them for their work, with the only ones remaining being Kosuke, Eiji, and the unconscious Ryudamon. Eiji looks on, and sees the DigiPolice retreating. He sees Ryudamon and asks if it was alive, to which Kosuke confirms it is. He asks what they need to do next, with Kosuke stating the next step was to crack into the gateway. He states they need to use the interfaces of the three Prototype Digimon, and that the fact they were so old meant the hadn't accounted for them which would make their hacking easier. He tells him of how he needs Vaccine, Data, and Virus Prototype Digimon and that all three of them were now present. Eiji asks what he and Loogamon needed to do, but he tells them they don't need to to anything — to their disappointment. The only thing that was needed was their presence, and they could just watch as Kosuke did the hacking. This has Eiji realize that's why Ryudamn was restrained, it didn't need to be awake or even do anything — it simply just had to be there. 
Loogamon, Dorumon, and an unconscious Ryudamon form a circle around a Hololized Tartarus — with Eiji complaining and saying if they had told him about all this from the start, he would've helped. Kosuke tells him that that wouldn't have worked, since they needed all three Prototypes to be able to digivolve to Ultimate, and he had only recently achieved that stage. Kosuke begins the hacking once Marvin returns, and, as Loogamon and Dorumon would be unable to fight during the process — Marvin and the other SoC members were the only defence they had. Marvin hadn't returned to Kosuke alone, he and the SoC members he brought with him brought a . Within seconds of arriving, it attacks the nearby Gatekeeper Digimon — taking them out with ease. Eiji wonders who was Mindlinking with it, but Marvin tells him no one was as it was too volatile and instead — he himself was controlling it with a bot. With no more enemies at the current point, he has Chaosdramon go on standby, but warns Kosuke that "you know who" would show up soon. With no enemies currently in sight, Kosuke begins hacking.

==Chapter 4-5==
As Kosuke Kisakata continues hacking into the system, the Sons of Chaos are attacked by Gatekeeper Digimon. and the SoC hackers Marvin brought with him are able to deal with them however, with Kosuke's hacking at 33% — which was 3% higher than when he had tried it in the past with only Dorumon. 
Gatekeeper Digimon continue to arrive, but the SoC deal with them every time. As more and more fights happen, Kosuke hacks even more, now at 66%. Loogamon senses something, and tells the others that "it's coming". As Eiji worries about Loogamon's warning, Dorumon tells them there's nothing they can do about it, with the situation becoming worse as their SoC allies needed to log out due to their Mindlink times running out. This would leave Marvin as the last line of defence. Before they can log out, they are attacked by a . Eiji was confused, since he thought the DigiPolice had retreated, and quickly learns that it was being piloted by a Mindlinked Satsuki Tamahime/. The Mekanorimon collapses, being heavily damaged, but had still been able to do this last attack. Numemon gets out of the now fallen Digimon, with Marvin asking why she was here. She tells him she was here to recuse Shuu Yulin, with Marvin laughing as she only had a Numemon with her. This wasn't the case though, and she pulls out a Digimon Dock and tells the unconscious Yulin/Ryudamon that she had tendered her resignation as she had broken the rules of the DigiPolice by stealing their secret Digimon. She activates it, unleashing a . 
Brigadramon aims its attacks at Eiji, Satsuki still wanting to kill him, but Marvin has Chaosdramon shield him. This was enough to pin Chaosdramon down, and with only Airdramon left — Numemon/Satsuki charge in to try and free Ryudamon. Eiji and Marvin are shocked to learn the DigiPolice had a Mega level Digimon the entire time, with Satsuki faking annoyance that Chaosdramon's Red Digizoid was able to withstand its attacks. With Brigadramon in range, Chaodramon grabs its arms but Satsuki reveals she wanted this to happen and had tricked him since it had missile launchers in its claws and as such would now be able to fire all of them at Chaosdramon at point blank range. Before it can do so, Eiji yells at them to stop fighting as "it" was here. of the had arrived. 
Omegamon attacks Kosuke, but Marvin is able to have Chaosdramon block the attack. As it falls to the powerful Royal Knight's attack, it is able to launch one final attack itself but Omegamon avoids it. Satsuki has Brigadramon attack Omegamon, though its attacks do little to it. Though she had no desire to help the SoC, she continues to have Brigadramon attack the Royal Knight as she didn't want Omegamon to kill Ryudamon/Yulin alongside the others. Brigadramon overheats, with it now unable to continue fighting. Omegamon comes out of the smoke unharmed, with there now being nothing to stop it killing Kosuke. The hacking was at 97%, and as Omegamon charged at Kosuke the mission seemed like it was going to fail. Kosuke however, reveals he had a trump card — and pulls out two Digimon Docks. He summons two Mega level Digimon and has them block Omegamon's attacks. With the hacking now at 99%, the gateway scans the three Prototype Digimon with its analysis bringing up holograms of their Ultimate forms. This confirmed they met the requirements, with the gateway giving Kosuke the key. The hacking was complete. Omegamon kills Kosuke's Mega Digimon but it is unable to reach the group in time as upon Kosuke activating the key — he, Eiji, and the Prototype Digimon vanish.

==Chapter 4-6==
Marvin Jackson watches as kills Kosuke Kisakata's two Mega level partner Digimon then tries to kill Kosuke to stop him completing the hack. Unable to do anything; he sees Kosuke, Eiji Nagasumi, and the three Prototype Digimon disappear. Figuring this meant Kosuke had completed the hack, Marvin celebrates. Satsuki Tamahime, who was also there, worryingly questions where Shuu Yulin and were. Omegamon, looking at its Transcendent Sword for blood — sighs upon seeing it had failed to stop Kosuke. The duo worry about the fact Omegamon was still there, since neither nor were able to battle. They didn't have to worry for much longer however, as Omegamon ignored them and leapt into the gateway to follow Kosuke and the others. This signified the end of the battle, with the Hackers/Digimon leaving alongside the remaining Wall Slum Digimon. Marvin thanks Satsuki for helping, though she instead demands to know where Yulin was. He tries to comfort her by telling her he lost friends during the battle, though Satsuki instead becomes further enraged at his comparing Hackers to Yulin. He returns and the corpses of Kosuke's two Mega level partner Digimon to their Digimon Docks, and leaves Satsuki on her own — though not before telling her that if she contacts him in the future he would be more than happy to fix the for her. 
Kosuke and the others find themselves in a void beyond the Gateway, with Eiji wondering if they had managed to reach the depths of the . As the Hackers and their partners discuss their surroundings, Kosuke pulls up a monitor — and after searching it informs the group they were in the Source Domain. Upon that realization, Yulin and Ryudamon wake up — with Kosuke giving a quick update on what had happened. Yulin is enraged, but is unable to do anything as Ryudamon was still restrained. Kosuke apologizes for doing so, and tells her he had no choice as he had to do the hack. She asks what happened to Satsuki, and is surprised to learn she had stolen Brigadramon. As the two talk, Eiji expresses shock at the fact Kosuke and Yulin actually knew other by name — the leader of the DigiPolice and the leader of the Sons of Chaos. Figuring there was no point in keeping secrets, Kosuke tells Eiji a brief story about the duo's time working with Tomonori Ryusenji back when they were students. With how long the conversation had gotten, Eiji asks if they can really stand around and do this since Omegamon could come for them at any moment. Dorumon alleviates his fears though, telling him that only Prototype Digimon could be in the Source Domain — and as such, Omegamon couldn't get in. It even states that King Drasil wasn't allowed in. Eiji breathes a sign of relief, though goes back to worrying when Dorumon says it actually has no idea if the Royal Knights were allowed in or not and was simply theorizing. As Kosuke states that they had finally reached the place where they could get the Sacred Chalice, Loogamon notices the nearby area's smell as changed. As it sniffs it more, the area Loogamon was sniffing changes shape.

 has just noticed the nearby area's smell as changed, and as such sniffed it. As it did, the area changed shape. As Loogmon and Eiji Nagasumi react in fear at the changes, Loogamon realizes it had seen the newly formed object before — it was the same device in Tomonori Ryusenji's office that displayed Vaccine, Virus, and Data. The three orbs on it, one for each Attribute, envelop the three Prototype Digimon, with it confirming the trio match the requirements. Now all Kosuke Kisakata had to do was hack into the source code of the system so he could get access to the Sacred Chalice. Phase 3 of Operation Tartarus was now complete, with Phase 4 now beginning.
As Eiji watched Kosuke hack, he realized that Tomonori had given him Loogamon and told him to infiltrate the Sons of Chaos all for this moment — so that he could digivolve Loogamon to the Ultimate level and help Kosuke free Saya Ryusenji. Shuu Yulin continues to try and break free from the restraints so that she could stop Kosuke from hacking into the , but still found herself unable to do so. As Kosuke states he would hack into the system, slipping passed King Drasil and the , Yulin continues to try and break free as she didn't want her former friend to become a target of the Royal Knights. She also didn't want him to upset the balance between humans and Digimon, just to free one human as the risk of the Digimon retaliating against the Human World was too strong. Kosuke insists it will all be worth it to save Saya, his fiancée and the Professor's daughter, this fact shocking Eiji since he wasn't aware of Saya's connection to Kosuke — never mind the Professor. This finally had Eiji realize just how important she was to Kosuke and Tomonori. Not actually caring about Saya, Loogamon tells Kosuke to hurry up as it was only interested in saving Leon Alexander and . Yulin tries to reason with Eiji, hoping he can put a stop to what was happening, but he and Loogamon tell her they had come too far to turn back now. Kosuke continues his hack, with the Attribute logos connecting together followed by lots of objects coming out of the ground — eventually forming a stone circle around the group. Dorumon and Loogamon, Loogamon pulling the restrained Ryudamon, approach the newly formed altar with the now woken Ryudamon telling them they can do what they want as they had bested it in combat. Dorumon states it will pay back the love Kosuke had given it by helping free Saya, but not just that — it would free the Digital World and change it. 
Eiji asks Kosuke if he knew how to find Pulsemon's data, to which he states he doesn't as he only had the information for Saya's . Loogamon points out it remembers Pulsemons scent, feeling that'd be enough, whilst Eiji pulled out the medicine he was given by Tomonori to cure someone of DMIA. As Loogamon sends the scent data over to Kosuke, Yulin reacts in shock having learned Tomonori was part of the operation. As Kosuke continues to hack, letters only the Prototype Digimon would understand appear with the trio decoding it. Kosuke's monitor suddenly shuts off however, ending the hack, with Tomonori arriving and greeting the group with a cheery "good morning".

==Chapter 4-8==
After regaining consciousness, Eiji Nagasumi realized everyone was lying on the floor, with unable to move. Loogamon was rebooted, and Kosuke Kisakata was unable to restart his virtual monitor. Eiji realized Tomonori Ryusenji was the one who said "good morning" to them, and the professor states he'll take over Operation Tartarus. 
Eiji, Kosuke, and Shuu Yulin are confused by Tomonori's presence, which the professor fails to understand, as he is the one who asked them to raise the Prototype Digimon for him. Tomonori then restrains and with the same tool used on , bypassing both of their security systems. Loogamon realizes the restraint tool was installed in them from the start. Tomonori states the restraint tool is part of the research tools installed in the Digimon handled by Ryusenji Electronics and the Digimon Linker. Eiji realizes the Digimon Linker's monitoring of his health and Loogamon's progress is all being sent to DDL. Tomonori reveals he can forcibly take control of their Digimon whenever he wants, even when they are mindlinked, and that their Partner Digimon are his tools.
Yulin realizes that while the Prototype Digimon are meant to access the Source Domain, the Digimon Linkers are meant to be a bridge between the Real World and , granting Tomonori access to the Source Domain. Eiji realizes Tomonori's image is a video feed projected from their Digimon instead of being properly hololized. Loogamon regains its memory of being captured by DDL employees in the Wall Slum and having the restraint tool installed in it. Kosuke angrily reacts to Tomonori's actions. Tomonori starts to decrypt the Data part of the Source Domain's code with Dorumon's interface and states it's only right the leading expert on Digital World research be the one to do this. Kosuke gets angry because they were supposed to be on the same side, and he also wants to save Saya Ryusenji. Eiji asks Tomonori about Saya, trying to learn the full story.
Tomonori explains how he covered up the accident with the Tartarus probe to protect Kosuke and Yulin, and his promise to look after them even after they left Ryusenji Electronics. He also tells Kosuke and Yulin he's proud of having invested so much in them, and asks them to see his current actions as him calling back the favor they own him. Eiji continues his question, realizing it makes no sense for Tomonori to fight Kosuke if they are both trying to save Saya. Tomonori reveals he has no interest in looking for , which confuses Eiji. Yulin asks Tomonori about a hunch she has had. Tomonori calls the universal directory information tree and summons an unconscious to the Source Domain, revealing one can easily search any Digimon by their identification code in the Depths of the Digital World.
Tomonori then summons BlackAgumon, also unconscious. The professor confirms his suspicion that a Partner Digimon survives their mindlinker's death. His words shock all in the room. Tomonori shows for a brief moment a video of Saya in a capsule full of colored fluid, revealing the videos he had been sending to Kosuke were fake, and Saya has been dead for a long time.
===Featured characters===
==Chapter 4-9==
The group has just learned from Tomonori Ryusenji that Saya Ryusenji, Tomonori's daughter, has been dead for a long time. Kosuke Kisakata, Saya's fiancée, refuses to believe it, with Tomonori finding Kosuke's reaction boring — since he had predicted that's how he would react. He did find satisfaction in the fact the fake hope that she was alive allowed him to control Kosuke though, since it had allowed him to achieve his goals. Eiji yells out to Kosuke that they had found the the Sons of Chaos had been looking for, with this snapping Kosuke back to reality. Still refusing to believe she was dead, he takes out the medicine that would sever her and her BlackAgumon's Mindlink connection. Tomonori tells Kosuke that the medicine was real, and would indeed work, and that the only thing he had lied about was the fact she had already died but asks him if he would be able to live with the consequences — what would happen if her consciousness had no body to return to? As he looked at the BlackAgumon, he found himself unable to administer the medicine. He didn't have it in him to find out if Tomonori was lying or not. 
Tomonori's hacking finishes, with screaming in pain — the pain causing it to pass out. Kosuke apologizes to his partner, with Tomonori telling the group they had no idea what Kosuke was going to do with the source domain once he had it. Kosuke tells Tomonori he hadn't needed to do any of this as he was simply going to give the credit to him anyway — since he only cared about Saya — though Tomonori didn't care as he was done with Kosuke. He would turn his attention to , and begin hacking it just like he had done to Dorumon moments before. Shuu Yulin, still Mindlinked with Ryudamon, asks Tomonori why he was doing this — since his daughter was dead — with Tomonori telling the group he was interested in the Source Digimon. Yulin tells him that trying to find it was too dangerous, to which he agrees, but had no desire to stop in his goals despite how dangerous it could be as it would satiate his boredom. Yulin tells him she had lost all respect for him, whilst Eiji declares him a traitor. Tomonori didn't care though, and tells them he was going to Mindlink with the Source Digimon.
Tomonori asks Eiji how he had betrayed him, to which Eiji changes his mind and decides he actually hadn't. He realizes that someone as talented and rich as Tomonori would never take interest in someone like Eiji unless it was to have him digivolve , and so couldn't betray him as he was never really on Eiji's side in the first place. Tomonori tells him that he was the perfect candidate to raise Loogamon, since his entire family were dead and his DS levels with Loogamon were high and that had he told him about the plan — neither he nor Loogamon would've developed as well as they had. Seeing that Eiji had understood what had happened, he became confused as to why he had taken the side of Kosuke and Yulin. As Tomonori questions Eiji, Loogamon gets up and tells Tomonori to shut up. Having heard enough, Loogamon asks why Tomonori hadn't put a stop to its digivolution to — since he had clearly been watching the battle — with Tomonori telling that watching the battle was more fun that stopping it, even had it resulted in Leon Alexander's death. This enraged the duo further, with Tomonori disappointed that they had supposedly betrayed him. He tells them that Leon knew his secret and had grown too strong — and so had to be dealt with. 
Eiji and Loogamon still had the desire to save Leon and Pulsemon. Their hearts become one, with this allowing Loogamon to break free from the restraints. This shocks Tomonori, with Loogamon telling him that it can delete any foreign objects within its body with its flames. Tomonori pauses his hack on Ryudamon, and turns his attention to Loogamon. Eiji readies his Digimon Linker, and tells Tomonori that this wasn't going to end well for him.

==Chapter 4-10==
 has just broken out of its restraints, with Eiji Nagasumi telling Tomonori Ryusenji that the duo were going to stop his plan to get access to the source code. Tomonori had already hacked , and, having paused his hacking of to hack Loogamon instead, tries to using his hacking tools to restrain it so that he could do so. As Eiji wonders how they would be able to stop him, since they couldn't attack a hologram, Loogamon tells its partner that the battle would most likely be against Tomonori's pawns. As he says that, Dorumon — having woken up during the conversation — attacks Loogamon. Eiji asks Kosuke Kisakata why he had told Dorumon to attack them, though Kosuke — who had not been paying attention to what was going on as he was still wallowing in despair — looks at the commotion and asks why Dorumon was attacking them. This has Eiji realize Kosuke wasn't behind it, with him coming to the conclusion that someone else must've been controlling its actions. He asks Tomonori if he was the one doing it, to which he confirms he was as he had hacked into Kosuke's Mindlink — allowing him direct control of Dorumon's actions. He forces Dorumon to digivolve, with Dorumon digivolving all the way to the Mega level.
With by his side, Tomonori asks Eiji if he was going to fight him or if he was going to join his side and allow him to complete the hack of the three Prototype Digimon. He tells him that if he helps him get access to the Source Digimon he would forgive his betrayal and would allow him to continue working for him. He states he would give him a free apartment, as much food as he wanted, and that if he took this offer one of the women working for him might fall in love with him — specifically naming Hatsune. He gives him to the count of ten to make his choice, with Eiji actually considering accepting since he could skip university and work for such a prestigious company and maybe even become one of the higher ups or use the money to make his own business. As it seems he was going to accept the deal, Loogamon reacts in shock, with Eiji explaining that he had already had a taste of the good life and wanted more. Tomonori reacts happily, and tells Eiji he will make sure he has a high salary, though Eiji reveals he was bluffing and instead was going to forge his own path by using the to bring people to together. Not amused by the deception, Tomonori gives him one last chance to reconsider but Eiji refuses and has Loogamon digivolve.
 attacks Dorugoramon, but its attack does nothing to its Mega level opponent. Tomonori sarcastically congratulates the duo on their attack. Yulin tells Eiji about Dorugoramon's attacks, and that it is very effective in both short and long range combat — with this leaving very little in the way of defeating it. Eiji is surprised upon hearing Yulin helping him, though she quickly points out the fact that Soloogarmon would lose from just one attack. Refusing that notion, Eiji and Soloogarmon declare they'll win and start mocking Tomonori. He sees through their ruse though, and tells them that since he isn't Mindlinking they wouldn't be able to stall him out and that all that would happen is that Kosuke would fall into DMIA — since Kosuke was actually the one Mindlinking with Dorugoramon. Even if that were to happen, Tomonori would still have control of Dorugoramon. Their plan thwarted, Soloogarmon uses its thrusters to fly into the air — in the hopes that it would be be able to avoid Dorugoramon's attacks and defeat it from the air. As Soloogarmon avoided the attacks, they notice Dorugoramon had suddenly stopped paying attention to them and realize it was now aiming its attack at Ryudamon and the others. Eiji was confused, since killing Ryudamon would make accessing the Source Digimon impossible, and realizes his actual target was . He was going to use Pulsemon as a hostage to get what he wanted. Not wanting his friend to die, Soloogarmon changes from aerial attacks to a direct attack but is easily defeated by Dorugoramon at close range. Tomonori tells Eiji he is lucky that he can't kill Soloogarmon, since he still needed it, and mocks the death of Eiji's parents. This further angers Eiji, with Tomonori telling him he had won since no matter what he did he still had Pulsemon. Tomonori motions to Pulsemon but reacts in shock when he sees that it, , and were no longer there. One of Eiji's arrives, with Tomonori realizing he had had his Tyrannomon do stuff whilst Tomonori was distracted with Soloogarmon. As Tomonori wonders where they had gone, he figures there was only one place they could be — the altar. Eiji and Soloogarmon try to tell the Tyrannomon to flee but they're too late, with Dorugoramon getting there within seconds. Dorogoramon attacks the Tyrannomon at the altar, though Soloogarmon is able to get there in time and block the attack — saving its allies. Tomonori becomes confused, since Eiji could easily replace the Tyrannomon, but Soloogarmon tells him to leave its friends out of their battle. Now even more determined to win, Eiji and Soloogarmon's hearts become even more linked — and with an even higher desire to save their friends — Soloogarmon digivolves to .

 has just digivolved to due to it and Eiji Nagasumi's desire to stop Tomonori Ryusenji and save their friends. Eiji and Tomonori have a back and forth about their ideals, with Eiji declaring he would take Tomonori out. Tomonori tries to bribe Eiji again, but it fails once again after Loogamon snaps Eiji out nearly falling for it again. The talking over, Fenriloogamon attacks the mind controlled .
Two of Eiji's take the Mindlinked Shuu Yulin/, , and to the nearby stone circles, with the third limping there having taken damage from Dorugoramon's previous attack. The group now safe, Yulin watches the battle between the two Mega level Digimon from afar. Kosuke Kisakata's realized hologram had hitched a ride on the back of the injured Tyrannomon. He apologizes to Yulin, then approaches BlackAgumon with the syringe he hadn't been brave enough to use on it, wanting to put an end to the years of his life dedicated to saving his fiancée — Saya Ryusenji. Rather than use it though, he ends up just telling "Saya" how her father had taken everything from him. Yulin tries to comfort him, then tells him to watch with her to see what Eiji and Fenriloogamon could do. As they watch the battle between the two Mega level Digimon, Yulin and Kosuke praise Eiji for all he had achieved despite the many setbacks in his life — as well as how strong his resolve was to save his friends. Figuring he still had one more thing left to do, Kosuke uses the syringe on Pulsemon.
In the middle of their battle, Fenriloogamon and the mind controlled Dorugoramon notice a giant pillar of light emanating from the stone circle. This has them realize Kosuke had used the medicine on Pulsemon.
In the real World, in the DDL Labs, Leon Alexander's Digimon Linker flickers to life.
Pulsemon runs into battle, and joins Fenriloogamon's side. Pulsemon and Leon's voices speak at the same time, the two of them still connected, with Tomonori fascinated to see Leon's mind trying to split itself from Pulsemon's. The battle comes to a halt, with Tomonori wanting to watch the medical history unfold before his eyes — which gives Eiji and Leon/Pulsemon the time to catch up. As they talk, Leon/Pulsemon eventually notices Tomonori linked with Dorugoramon and asks why he was doing so. Tomonori tells him he was simply fighting the Sons of Chaos, and was currently in the middle of a battle with Eiji — claiming he was now one of the SoC's leaders. He uses his fake personality to try and smooth over Leon, telling him that they had finally managed to reach the , but that Eiji and the Sons of Chaos were trying to ruin it for him and so they should team up to stop Eiji. Eiji defends himself and tells Leon/Pulsemon that the enemy was Tomonori and not him, with Pulsemon digivolving upon hearing this. 
Yulin, seeing everything happening from afar, was shocked to see someone recover from DMIA. Kosuke explains the medicine to her, though also tells her they had yet to use it as they were worried about any potential side effects. He notices that Leon hadn't seemed to have suffered the effects of any of the side effects, and wonders if he will allow Eiji — a code cracker — to do what he wants. 
Tomonori and Eiji both yell out for Leon to take their side, with Kazuchimon answering by attacking Dorugoramon. Tomonori was shocked, and asks why he had turned on him. Leon/Pulsemon tell him that Kosuke was the one who had saved him, and that Eiji was the one who had been looking for him the entire time — with Tomonori having used them as blackmail to try and stop Eiji in combat. He reveals he had heard everything that had happened even though Pulsemon was unconscious and states that though he could never stand beside a code cracker under normal circumstances — he could put it aside for now as he was even more against someone trying to cause an irrational loss of life in the Digital World by wanting to play God. Leon/Kazuchimon tell Eiji that they could trust him more than Tomonori, as Eiji having unlocked his partner's Mega form showed he was worth trusting compared to Tomonori who had caused Dorumon to digivolve to Mega by force. Before the battle continues, Eiji tells Tomonori the main reason lost his trust for him was because he wasn't Mindlinking and risking his life and was instead just controlling Dorugoramon from within the safety of his office. Tomonori tries to defend himself, saying the mission only had a fifty percent chance of working — meaning he didn't want to risk his life over something that might not actually succeed — though Leon/Kazuchimon tell him that such cowardice means he will be unable to win the battle. Leon/Kazuchimon offers Tomonori the chance to surrender, since it was now two against one, though he refuses as he thinks it's his former employees who had no chance of winning. He starts to hack, reminding the duo he had gained access to the source code, and as he does, Kosuke's hologram collapses. Yulin freaks out, confused as to what was going on, with Eiji and Leon/Kazuchimon noticing something was happening to Dorugoramon's DigiCore. Large amounts of data begins to pour into Dorugoramon's DigiCore via its interface, with everyone realizing that if it continued — Dorugoramon would die as its body would be unable to handle that much data. Wanting to save Dorugoramon, the two Mega Digimon try to attack it — but are too late. Dorugoramon, in a bid not to die, began Death-X-evolution.

, not wanting to die due to the large amounts of data Tomonori Ryusenji was forcing into its DigiCore via hacking, Death-x-evolves to . and had tried to stop it before it could complete the digivolution, but were unable to do so. Eiji Nagasumi compares the situation to when digivolved to , whilst Tomonori boasts about having learned about Death-X-evolution via the source code and had decided to put it into action right away so that he could use it to defeat his new found enemies. Eiji, seeing DexDorugoramon, is reminded of his now deceased dog and realizes that Dorugoramon was dead. Instead, it was now a zombie with its mind being controlled by a virus. It had even taken in the data of various other DigiCores, technically no longer being just Dorugoramon. Tomonori realizes that DexDorugoramon was now the closest being to the Source Digimon, and that if he continued he would finally gain access to said Digimon, and has DexDorugoramon attack its enemies. As Fenriloogamon and Kazuchimon are taken out with only one attack, Eiji and Leon — their Digimon suffering from the effect of the attack — discuss the fact that DexDorugoramon was this strong with only one third of the source domain's power and that they could not allow him to win and gain the rest of the data by hacking and . If they allowed it to happen, he would gain access to the Source Digimon and could rule the World. At this point, Tomonori yells out he no longer had control of DexDorugoramon and had instead had managed to program it to work in auto pilot and had commanded it to eat the DigiCores of Loogamon and Ryudamon so that it could become the ultimate Prototype Digimon. As the battle continues, Leon tells Eiji to flee — since they could not allow it to eat Loogamon's DigiCore — and tells him he will fight in his place as thanks for saving him. Eiji refuses though, telling him he was done running away and crying as he had done enough of that after seeing Leon fall into DMIA. Leon tries to change his mind, though Fenriloogamon tells him to shut up and that they were not going to abandon their friends. Surprised they still wanted to be friends, Leon confides in Eiji that he didn't think he had it in him to defeat Tomonori because of what they had been through but wonders if he could do it with Eiji, Pulsemon, and Loogamon by his side. He tells Eiji that, although they were on different sides, he still believed in him, with Kazuchimon putting his hand against Fenriloogamon's interface. Leon tells Eiji he had earned Kazuchimon's power, this causing their partners to Fuse together — the duo becoming one as . 
Tomonori was surprised to see just how much Leon hated him, to the level that he would even team up with a code cracker. Leon tells him he cannot live with pride until he defeats Tomonori, with Eiji telling him he had gone way too far. As they readied an attack to defeat DexDorugoramon, Eiji's Mindlink timer rang — meaning no matter what happened, this was the final attack. Tomonori declares he will have DexDorugoramon eat both of them and end their lives, though they both tell him to shut up. Fenriloogamon Takemikazuchi then launches its attack.
