Continuity and Placement


"According to this book, in September of 2018, the ordinary high school student Sougo Tokiwa embarks on a path which leads him to become the demon king of time, Oma Zi-O. In the timeline of 2017, he is victorious in defeating Another Build. After which he takes the power of Build, creating a timeline where Kamen Rider Build never existed. Thus he takes his first step down the path to becoming a demonic king. He then comes to find Genius Gamer M and... Oh, pardon me... I suppose that is still in the future, for you."
In his house, Sougo is having breakfast with his new roommates, Tsukuyomi and Geiz. After some shenanigans involving Geiz threatening him, Sougo is surprised at knowing that they're transferring to his school to watch over him.

At 2018, Ora meets up with Heure and have a conversation about Zi-O and whether or not he could affect their plans. Ora then appears in 2016 in front of a grieving father, Ida, and forcefully transforms him into Another Ex-Aid by offering him a Faustian deal to save his son in exchange for doing her bidding.

Back at school, Tsukuyomi and Geiz follow Sougo everywhere until he managed to escape into a sports shack. In there, Sougo meets Owada, his classmate, who's trying to finish "an unwinnable game". Sougo declares Owada as his future cyber security minister if he becomes king... but suddenly another Ex-Aid appears and attacks Owada. Sougo transforms into Zi-O and attempted to attack the kaijin, but he disappeared.

After taking Owada to the hospital, it appears that the doctor doesn't know how to treat him. Sougo tries to hunt for Another Ex-Aid, but Geiz stops him. Geiz said that whenever Sougo uses Zi-O, he steals power from the Legend Riders, thus making them disappear forever, just like what happened to Build. Sougo says he can't just stand around and watch people suffer, he has to try and help. He then asks Geiz if he has ever felt that way. Geiz gets angry and grabs Sougo, then has a flashback to the battle against Oma Zi-O, where someone he cared about died in front of him and he mourned him. Geiz then tells Sougo that he does know what its like, more than he can possibly imagine. Sougo then finds Owada's Genm Corp. game console, which fell out of Geiz's pocket, thinking that the game is connected to the Another Rider. Sougo said that Geiz is actually a nice person if he's worried about the Legend Riders, but Geiz rejects him in embarrassment.

Back in his home, Sougo tries to play the game but he's really bad at it. Geiz mocks him, wondering how could a complete amateur like Sougo trying to find a secret behind unbeatable game. Sougo then realizes that to finish the game, he must find a real gamer, thanking Geiz in process. Tsukuyomi browses info about that gamer on her futuristic tablet, citing the Genius Gamer M, a legendary gamer that can beat any game.

Sougo tries to look for M in many game centers and arcades, but he can't find him as no one knows M's true name. Some time later, he comes across Another Ex-Aid's rampage, but he's still too late as the kaijin disappears after attacking the victim. Then, Woz appears again and gave Sougo a clue according to his book: Sougo must take the victim to Seito University Hospital.

In the hospital, some nurses are talking about a doctor who has been absent without notice again, suspicious that he played video games all night again. Sougo wonders if the new doctor is actually M, but when he tried to ask the nurses, an entourage of doctors appear, led by the genius surgeon of Seito University Hospital, Hiiro Kagami. Sougo approach Hiiro and asks about the case of unwinnable game.

Hiiro took the three of them into a special treatment ward for the victims of this case, and said that the pediatrician is researching it. The surgeon then took Sougo and co. to said doctor's workplace and found a note in German. Geiz succeeded in deciphering the note, as it contains a code to the unwinnable game. When Sougo inputs the code, they're transferred into a game stage as the GENM handheld generates a Game Area, with Another Ex-Aid waiting.

They transform, but the kaijin is using the game power of Ex-Aid and proved too strong and maneuverable. Geiz then equips the Drive Armor as Sougo equips Build Armor, and they managed to defeat the monster with teamwork. As it reverts back to Ida, a lone person appears that Tsukuyomi identifies as Emu Hojo: the genius gamer M. Emu coldly tells them to leave him alone, as he transforms into Ex-Aid Action Gamer Lv 2 and attacks the two Riders...
