Hacker Leon: WWW Airlines flight 626

Hacker Leon: WWW Airlines flight 626, known in Japanese as Hacker Leon:WWW Airlines flight626, and Chinese as, is the second chapter of Digimon Seekers. It is currently split into eight parts.

Synopsis
In the middle of the night, Leon Alexander wakes up screaming having had the same nightmare about the accident once again. A hololized rushes to its partners side and asks if he's okay though Leon insists he's fine. Pulsemon tells Leon to go back to sleep since he has an early class the next day though Leon rejects the idea and instead decides to get up and start his day. He complains about the teacher, leading Pulsemon to wonder if he even needs to bother graduating since he works for Abadin Electronics already though Leon insists he has to as he promised his father he'd graduate and that being a college student with too much free time lets him do "other things" anyway. As Pulsemon jokes about that being "ethical hacking", Leon goes to the bathroom to have a shower.

Still in the Wall Slums,, having de-digivolved from at some point, and a hololized Eiji Nagasumi, talk. Eiji asks Loogamon if it had got its memories back, though Loogamon tells him that its memories were fragmented, hazy, and lacked details and it only knew it had ran the area due to the smells there. Despite this, Loogamon didn't care it lacked its memories anyway since it didn't want to be the type to cling to memories. Eiji's three return, having previously been sent out to collect map data and estimate the population within Ninth Avenue. Loogamon tells Eiji to have the Tyrannomon continue to patrol this way, so as to make sure no one could invade its territory, with Eiji telling them to do just that. A siren blares, causing the Digimon of Ninth Avenue to flee, with Loogamon telling Eiji to recall the Tyrannomon. As Eiji questions it he looks into Loogamon's eyes, realizes its serious, and does as he's told. Loogamon runs up the side of the Caste of Nine Wolves to assess the situation.

Upon reaching the top of the Castle, it looks out at the Net Ocean in which it sees a giant whirlpool. Eiji asks about it, to which Loogamon states its dangerous and that the Walls are meant to protect them from things such as those but that sometimes things get through it. As they talk, the whirlpool destroys a section of the Wall Slums — also killing all the Digimon living inside said area. After doing so, it disperses. Eiji's alarm goes off, causing him to end the Mind Link and return to the Human World as he had an appointment with Tomonori Ryusenji to attend.

Eiji goes to his meeting with Tomonori, who congratulates him on his recent results with Loogamon. Eiji tells him that he had been accepted into the Sons of Chaos and informs him of his trial mission and tells him it was easy since Loogamon had lived there before. Tomonori tells him that Abadin had collected Loogamon from Ninth Avenue to keep it safe, though doesn't expand on that when asked. Eiji continues to tell him about the mission, and about the fact that Loogamon had regained some of its memories, with Tomonori telling Eiji to be there for Loogamon when it gains its memories as regaining them can cause mental anguish. As Eiji affirms he will, he is given a reward due to helping Loogamon digivolve to Champion and is tasked to continue looking into the Sons of Chaos. He tells them he already has a meeting set up with the higher ups of the group, impressing Tomonori — who becomes even more impressed upon learning his meeting will be with Marvin Jackson. He reminds Eiji not to blow his cover, then opens up a file for him to see stating it is so important it is a matter of life and death.

Synopsis
Eiji Nagasumi logs into GriMM and accesses the Sons of Chaos' channel to attend his virtual meeting with Marvin Jackson, taking with him. As the duo talk, making sure they're set to private so that no one could hear them, Loogamon notices it was being scanned by someone and quickly notices Marvin — and his partner — approaching them.

They exchange introductions, followed by Marvin asking if Eiji had ever applied to the SoC under a different name or if he had belonged to other cracker teams, as it was unusual for such new cracker to be able to defeat the DigiPolice like he had. He figured either the information was a lie, or Eiji was up to something. Eiji, now fearful that the SoC had already caught on to him, states he hadn't and had simply been a freelancer until recently, with Marvin figuring that a Mindlinker probably wouldn't be stupid enough to pull something. The four of them go into Marvin's private room, where he tells Eiji about their upcoming plan and that they don't have enough members to pull it off. Eiji questions that, since the SoC have a lot of members, though Marvin says they need A class hackers that can Mindlink and that there are very few of those. With Eiji fitting that criteria, he instantly offers his services without listening to what it was with Marvin surpirsed since it would obviously be dangerous. Marvin praises him for defeating the DigiPolice, whilst Eiji asks if Tartarus will be part of the mission claiming he idolizes him with him being the entire reason he joined. Marvin becomes distracted as Airdramon begins to play with Loogamon — Marvin deciding to join in too — though answers Eiji after doing so, telling him that though Tartarus set up their missions, he rarely gets involved in himself. He shares a file with Eiji, telling him that the mission was named "Operation Infinity", and that he should return Mindlinked the next day. Just as Eiji bids farewell, Marvin asks him if he had heard anything about a BlackAgumon though Eiji states he only knew that someone was looking for one. Marvin reveals it was actually the SoC that were looking for it, with Eiji surprised, since the reward was 100 million. Marvin informs him that 100 million was nothing for SoC, especially as Tartarus was obsessed with getting his hands on a BlackAgumon.

Synopsis
Eiji Nagasumi joins the other members of Operation Infinity in Marvin Jackson's SoC room, with there being eight users there total. The monitor displays the mission, with Eiji learning they will be hacking X Nation's server. Eiji is surprised, and questions the other users about doing such a thing, which leads the others to laugh at him. Marvin tells him that all members need to be on the same page, then informs him that hackers from X Nation had performed lots of cyberattacks and had even recently stolen billions worth of cryptocurrency – with Eiji surprised to learn that they were the ones responsible for it. Since the SoC use cryptocurrency they couldn't turn a blind eye to them doing such a thing, especially if it caused a major shift in the World's financial powers. Eiji continues to be surprised, since hackers do so to become rich meaning this was hypocritical, with the other hackers stating they just wanted to destabilise X Nation's leader as well as get revenge on them, as they had done crimes using a Machinedramon and framed the SoC. Tartarus arrives, introduces himself as the leader of the SoC, and then tells them to render their server useless and capture their Machinedramon. After cheering, the hackers – including Eiji – summon their partner Digimon and Mind Link with them.

Eiji thinks back to an earlier meeting with Tomonori Ryusenji, where Tomonori shows him video footage of the person who had Mindlinked the most. The person's body has negative reactions to Mindliniking with the person convulsing and having to be attended to by medical personnel. The man eventually ends up motionless, seemingly dead, with Tomonori telling Eiji that the higher level the Digimon the less time they can spend Mindlinked warning him something like what happened to the man in the video could happen to him too. Should Eiji spend too long Mindlinked his mind will never able to to return to his body, and his body will die shortly afterwards. His consciousness would still remain within Loogamon, though he would be forever trapped within his partner. Tomonori sets a warning system within Eiji's Mindlink and tells him to return when it tells him to to avoid falling to the same fate.

Synopsis
The Sons of Chaos have their eight members split into teams of two, with the Mindlinked /Eiji Nagasumi travelling alongside /Marvin Jackson. Eiji asks Marvin what Tartarus will do with X Nation's Machinedramon once they have it, with Marvin becoming annoyed at Eiji for being more interested in Tartarus than the mission. He tells Eiji that even as Tartarus' right hand man he barely knows him and has no clue why he wants Machinedramon. Eiji insists that isn't the case and he was super focused on the mission, even to the level he hadn't slept – which causes Marvin to realise he had been overestimating Eiji as not sleeping could cause him to make a mistake and ruin the mission. Eiji continues to ask questions about Tartarus as they travel, with Marvin answering with theories rather than actual answers. A vortex appears, though it quickly disappears, with Marvin warning Eiji about them. Eiji and Marvin discuss rumours of people supposedly going into them and living with Marvin not believing them as he hadn't known a single person to go inside one and come back. They eventually reach X Nation's servers, and begin their attack.

Airdramon and Loogamon fight and defeat Digimon belonging to X Nation hackers, with Marvin telling Eiji not to digivolve to Champion as staying at Rookie will allow him to Mindlink longer and get both of them out once Marvin runs out of time. The other teams were simply decoys for Eiji and Marvin, making it even more important for them both to avoid running down their times any longer than needed. They are stopped in their tracks by a wall, with Loogamon stating Machinedramon was behind it. Airdramon complains at how much power it will take to destroy it, though Loogamon tells Eiji to set his tool to Decode which – to the shock of Marvin – allows Loogamon to decrypt the wall in an instant.

As they pass what used to be a wall, they are greeted by the roar of Machinedramon. They see it was held in place by a bunch of tools, meaning it wasn't a threat, with Marvin sending his Airdramon to attack it. He has Airdramon digivolve to and attack Machinedramon, trying to free it. Eiji's monitor suddenly alerts him to the fact another Mega had just shown up, which proceeds to easily defeat Megadramon.

Synopsis
Marvin Jackson's has just been defeated by the newly arrived, with Eiji Nagasumi and  looking on in shock – unaware of who had even defeated it. They panic, looking over Megadramon, worried for Marvin since if it takes enough damage it could kill not only Megadramon, but Marvin as well. The other Sons of Chaos members arrive, and ask Eiji why they hadn't captured Machinedramon yet. They see Marvin's Megadramon knocked out and wonder who had done it, since they had acted as a decoy to keep most of X Nations defences busy. They shoot down Eiji's suggestion that maybe the DigiPolice had caught onto their plan, since the Japanese police hacking another countries server would cause a massive international incident. Kazuchimon proceeds to defeat every member of the Sons of Chaos, including Loogamon, with the SoC members realizing who it was as only Leon Alexander was known to own a Kazuchimon. Unable to do anything, they watch as Kazuchimon kills the still trapped Machinedramon. Leon tells it to return to being a and hopes that upon its revival it would be taken in by a nice person, rather than an evil hacker. He tells the SoC that he had decided to help their operation to stop X Nation doing crimes but couldn't allow them the pleasure of doing it themselves as he hated all hackers. Loogamon tells Eiji they need to flee as the mission was a failure, with Eiji refusing to leave Megadramon/Marvin behind. Loogamoon protests as they weren't friends with Marvin, but Eiji refuses to budge as he thought Marvin was as nice guy and he actually had become friends with him. He tells the other members to get Megadramon to safety, and as they do so he will distract Kazuchimon. The other members doubt he could defeat a Mega but Eiji simply tells them to do as he says.

As they try to do so, Leon demands to know where Tartarus was and tells the SoC he will ruin their reputation as he had heard none of their missions had ever resulted in one of their members dying. Feeling cocky, Leon has Kazuchimon de-digivlve to figuring that as he had already taken out Megdramon and Machinedramon he no longer needed to waste some of his Mindlink time at Mega as he would still be able to kill the other seven with his partner at the Ultimate level. Loogamon points out that as Leon was mindlinking he was on a time limit as well, and figures they could save everyone by stalling long enough. Loogamon digivolves to and attacks Boutmon, with the force of its attack enough to stop it before it could reach Megadramon. Leon is surprised at just how strong Loogarmon was, with Eiji mocking Leon, telling him that he had actually de-digivolved as he was almost out of time. Megadramon wakes up, with Marvin telling everyone to flee as well as telling Leon he had committed a grave mistake in making an enemy of the SoC. Boutmon de-digivolves to and as Eiji looks at it, he recognizes it and wonders why. He then remembers, his childhood best friend Leon had shown him his partner Digimon a long time ago with it being the same exact Digimon. Realizing that meant he was fighting Leon, he Hololizes – which also causes Leon to hololize as well. Not only was Eiji surprised to see Leon, Leon was surprised to see Eiji. Their reunion is cut short however as more X Nation hackers arrive, causing everyone to flee before they could be taken out by the reinforcements.

Synopsis
As Marvin Jackson is in his room in the Sons of Chaos' GrimM channel, he is visited by and the Hololized Tartarus, who was using his interviewer account. Dorumon asks how was, with Marvin stating that it was okay but would be out of action for a while due to the injuries it had sustained. He tells Dorumon that Eiji Nagasumi, the hacker that Tartarus had personally scouted, had saved him and wonders if he should retire having lost that badly. Social media had become ablaze with rumours about how Judge had single handedly defeated the SoC, with the SoC themselves having leaked this information. Dorumon and Tartarus tell Marvin they would not let Judge get away with it and would get revenge against him as he poses a threat against not just the SoC but the entire. Marvin asks if the duo are going to go ahead with their plan for an all out war, with them confirming that even with the loss of Machinedramon the final piece of the puzzle had still fallen into place. They discuss Eiji and, saying that they had only seem him digivolve to Champion and as such didn't know whether they could trust them to stick with them till the bitter end without seeing their full power. He asks Marvin if he is still dedicated seeing Tartarus's plan to the end, to which Marvin confirms he is.

Having severed their Mindlink, and Leon Alexander wake up in the real world. Leon takes off Abadin Electronics mindlink endurance test apparatus, with the duo congratulating each other on their success at breaking the Mindlink world record. Tomonori Ryusenji arrives and congratulates the duo on having gotten revenge for the entire country of the United States of America, stating that X Nation's Machinedramon had been responsible for WWW Flight 626's crash, which resulted in the deaths of over 100 Americans. Leon was pleased with this, since he wanted to get personal revenge against them for said terrorist attack against his home country.

Leon thinks back to many years before, when he had visited Abadin Electronics with his father. Tomonari had shown Leon a video of the, followed up by him giving him Digimon Dock with a on it figuring he could raise the Digimon well. Leon had lots of fun raising the Digimon, and upon digivolving it up to the Rookie level showed it off to his best friend – Eiji. The two bonded over how cool Pulsemon was, though their friendship eventually drifted apart as exams kept them busy which was followed up by them going to different schools. This got even worse when Leon moved back to the United States. He remembers how he had spent his youth desiring to study Digimon and upon becoming old enough applied to join Tokyo University of Electrical and Computer Engineering since it would allow him to return to Tomonori, who worked there. During this time, he had also given updates on Pulsemon, with Tomonori telling him how to upgrade his Digimon Dock as thanks. As he learned more and more about Digimon, he learned about the rampant amount of Digimon related crime and was able to fight against them with Pulsemon. He was able to learn about a battle that was going to take place between some cyber terrorists and the American police but was unable to do anything as Machinedramon easily defeated Pulsemon and took out the plane killing over three hundred people of varying nationalities. He remembers feeling disgraced at losing so easily, and how he had taken on mission after mission to increase his strength so that he could one day get revenge. He trained not only Pulsemon, but himself, becoming not only the smartest person in his school but a master martial artist as well. Desiring only to stop Digimon related crimes, he turned down multiple opportunities wanting only to work under Tomonori – which he had managed to achieve upon returning to Japan. He had even turned down woman after woman, with women throwing themselves at him due to his smarts and strength but was focused only on stopping crime and had no time for dating. He had become so smart, he even advised the United States government, police, and military. Now able to access to the Digital World as a worker of Tomonori, Pulsemon became stronger and stronger with the duo becoming famous. He eventually stops remembering the past, and tells Tomonori he has to leave to go to a meeting...as he had reconnected with Eiji online and agreed to meet up with him.

The leader of X Nation states on live TV they would get revenge against the for what they had done. Eiji watches on a TV in a different part of the building and feels uplifted by it having played a part in the nation's defeat. As he watches, Leon arrives and walks up to Eiji.

Synopsis
Eiji Nagasumi and Leon Alexander, having recently fought during a mission, meet up, with the duo having been childhood friends. This being only the second time they had seen each other since elementary school they go to a the café within DDL to catch up. Leon shows off to him once again, having done so when they were kids, with Eiji showing off  as well... though the air between the two Digimon was tight and awkward since they had been fighting only days before. They express shock upon learning they both work with Tomonori Ryusenji with Leon annoyed at the fact he'd hired Eiji to do things for him instead of having Leon do them since he was his assistant. Pulsemon pokes fun at Loogamon for only being able to get to the Champion level, something Loogamon isn't amused by, with the duo arguing over and over till their tamers put an end to it. As Leon tells Eiji he was the only person other than his dad that ever understood him, Hatsune and her friend, who had recently been hired to work for DDL, interrupt their conversation with Hatsune's friend fangirling over how cute the Digimon were. Hatsune was surprised to learn Leon and Eiji were friends, which was followed up by her friend fangirling over how hot she thought Leon was. Hatsune tells her friend not to harass employees of their boss, after which a big TV in the room plays the recent announcement from the leader of X Nation, in which he states he will get revenge against the hackers, with the four of them watching it.

Synopsis
After breaking Eiji Nagasumi's heart by saying that hackers are lame dangerous depressed weirdos, Hatsune's friend is taken away from Eiji and Leon Alexander by Hatsune so that she would stop interrupting the boy's reunion. The surprise of the boys, their Digimon argue over which of the two girls was cuter. Eiji and Leon continue their conversation, which moves to how they should be treating their partners as actual lifeforms rather than AI. Eiji tells Leon how he had recently changed his perspective and began doing just that thanks to Tomonori Ryusenji, with the mood changing completely when Leon tells Eiji he should quit not just the Sons of Chaos but hacking as well. This angers Eiji, since he had to do work as a hacker to make money — unlike Leon who attended a prestigious university and had a well paying job as Tomonori's assistant. This outburst surprises Leon, since the Eiji he remembered had good grades and asks how he ended up down this path as a hacker instead of something more reputable. Eiji brings up WWW Airlines flight 626, which instantly upsets Leon due to his personal history with it. As Leon refuses to talk, Pulsemon interjects and talks about the event instead with Leon learning Eiji's parents were two of the 300 killed by Machinedramon that day. Leon was shook, since he considered it his fault it had happened, feeling even worse now he had learned his childhood best friend's parents were on board and he had been unable to save them. Now knowing Eiji's personal history, he becomes confused as to why Eiji would work as a hacker with Digimon when one was responsible for his parents deaths. Eiji states he doesn't blame the Digimon but instead blames the hackers and though he isn't proud of being a hacker it was the only way he could make a living. Working with Tomonori had finally had him feeling proud of himself, something he figured Leon would understand as he worked with him too. Leon asks what Tomonori has Eiji doing other than raising Loogamon, though Eiji tells him he isn't allowed to tell him and leaves saying he has an appointment with Tomonori to attend. Pulsemon gives Loogamon a bunch of files before he leaves, with Eiji saying they should do this again sometime but without all the complicated stuff.
