Eiji: Wolf of the Ninth Avenue

Eiji: Wolf of the Ninth Avenue, known in Japanese as Eiji: wolf ninth avenue, is the first chapter of Digimon Seekers. It is currently split into nine parts.

Synopsis
Three chase their prey, a, around the subway. Just as they were about to trap their prey in a corner, a subway train drives passed with the Tyrannomon having to get out of the way to avoid being run over. They continue to chase their prey, with it running into the nearby sewers. As they look for their prey, one of them is suddenly defeated by a surprise attack from the ModokiBetamon.

As Eiji Nagasumi watches a local restaurant's mascot jumping around to promote a new burger, he wonders if there are any part time jobs he can apply for. He browses through GriMM on his smartphone looking for one. As he looks through, not interested in most of them, he eventually comes across a high paying advertisement looking for someone to capture a BlackAgumon for them. Though initially excited, he loses his enthusiasm upon seeing the negative comments on the post and assumed it was a hoax listing. As he sighed, he received a notification that one of his three Tyrannomon had been killed and — not wanting to fail the mission since he needed the money — quickly replaces the defeated Tyrannomon with another one. He then continued looking for part time work.

Synopsis
Eiji Nagasumi travels to Abadin Electronics's headquarters, as he had accepted a job from them. The receptionist, Hatsune, helps him sign in on the nearby tablet, though half way into filling it out he instead pulls out his smartphone and texts his client — Professor Tomonori Ryusenji — that he had arrived as putting so much information into it was annoying him.

As Eiji marvelled at a nearby 3D image he is approached by Tomonori, who refers to Eiji by his alias "Fang". Eiji introduces himself with his actual name, with Tomonori telling a flustered Hatsune to give Eiji a guest pass and a co-researcher pass as they were going to visit D4. He escorts Eiji to D4 and tells him he plans to show him Abadin Electronics' top secret project. As Eiji was about to follow Tomonori in, the security guards perform a security check on him and take away his personal belongings.

Synopsis
Having been allowed to follow Tomonori Ryusenji into D4, Eiji Nagasumi watches a presentation on the nearby computer which explains to him what the Digital World and are. It explains that most people don't know about them, then segways into talking about how criminals had been using Digimon to help aid them in their illegal activities. The presentation shows footage from someone who was on a plane, with the footage showing the plane falling from the sky — having been shot down by someone who owned a Digimon. This freaks Eiji out, and he decides he didn't want to see any more.

Tomonori takes Eiji to his office where Eiji gives him his Digimon Dock. He puts it into his lab equipment and happily celebrates when it hololizes and shows that Eiji had managed to capture the he had asked him to get. Eiji, having seen a Betamon during the presentation, is confused as to why Tomonori wanted a ModokiBetamon since he already had a Betamon and didn't know what made them different other than the difference in color. Impressed that Eiji had noticed the difference in the first place, Tomonori gives him a bonus on top of his regular payment which makes Eiji happy as it would allow him to buy some more expensive food to eat later than night.

Tomonori asks Eiji what he thought of the earlier video, and though he hadn't enjoyed the plane part, said he enjoyed the video. He tells him that they had previously planned to open up an amusement park named Digimon Land with Eiji saying he liked the part where it said Digimon were "living A.I. creatures" and thought it was cool fiction and that if he were still a kid he would've loved it even more. Tomonori, hearing heard what Eiji had just said, tells him that Digimon are not fictional, they are real.

Synopsis
Eiji Nagasumi, having just heard from Tomonori Ryusenji that Digimon were real, laughs and says it would be cool if they were actually real. He asks Tomonori when they plan to make Digimon Land real, though is disappointed when he tells him that they had shelved the plans. Eiji comes to the conclusion that they had done so as some people used Digimon to commit crimes, figuring that's why Tomonori had brought up Digimon crimes earlier. Tomonori explains that crimes involving Digimon were not known to the public as World leaders had covered them up, but that it would cause an uproar if anyone found out that the same creatures in Digimon Land were also being used to do crimes and the media would probably create a media storm calling Digimon and the Digital World evil. This fact upset Tomonori, who once again said that Digimon are real.

He asks Eiji if he wants to know the truth about the Digital World and what was inside of it, which Eiji agrees to as he wanted to see what Tomonori had been seeing. Having originally thought that the video footage was made on a computer, Eiji realizes the footage was in fact real and reacts in excitement about the fact he had learned that Digimon were actually real. Now aware that they're real, he feels bad about the fact that one of his had died.

As Tomonori tells Eiji that he had dedicated his entire life to researching the Digital World, the transfer of finishes. Tomonori picks up Eiji's Digimon Dock and throws it towards the trash can, with Eiji reacting quick enough to catch it before it went into it. Annoyed, since he had spent a lot of money on it, he asks Tomonori why he had done so, with Tomonori telling him that there was an error in its memory and that the error had nearly destroyed the ModokiBetamon during the transfer due to how old his Dock was. Eiji tells him that he can't throw it away, since he doesn't have much money, and that the old Dock was all he had. Hearing this, Tomonori gives him a brand new Digimon Linker which had already been calibrated to work for Eiji — since he had always planned to give it to him in the first place. He then shows Eiji that the Digimon Linker wasn't the only gift he had given him, pressing a button on the device to show that he had also given him a new Digimon —.

Eiji accepts a new job from Tomonori, and returns to the reception hall to admire it. Hatsune notices him and tells him to return his passes, then notices the Digimon Linker on his arm. He shows it off to her, with Hatsune surprised her boss would give him the new secret prototype and figured he must trust Eiji a lot. She then brings up that he hadn't actually finished filling in the form on the tablet and asks him what his job is so she can finish it for him. After a long thought, he tells her he's a code cracker.
