## Plot

### Toman Arc

Naoto is being bullied by some guys, however, Takemichi Hanagaki manages to chase them. Takemichi gives Naoto advice to be more confident and not back down, which will scare off the half-assed punks. Learning that Naoto is Hinata's little brother, Takemichi tells him to take care of his sister and reveals that on the same day in 2017, he fell into the train tracks and ended up 12 years in the past. Takemichi reveals that on July 1st, 2017, he and Hinata will die, so he must remember that date and protect his sister. Naoto takes this seriously and Takemichi then shakes Naoto's hand.

Naoto saves Takemichi from the train track incident. As Takemichi awakens in the infirmary at the station, Naoto reveals that Takemichi had time traveled and had changed his fate and in return Naoto managed to save him. Naoto reveals he studied really hard and became a police officer, however, he still wasn't able to protect Hinata, who still died. Naoto then asks Takemichi to help him save his sister and Takemichi agrees.

Naoto explains that his power is time travel and he is able to jump on the exact same day but 12 years ago. Takemichi spends two days without sleep in Naoto's room, where Naoto gives him all the information he had obtained about Tokyo Manji Gang and wants him to remember it. Some of the information he is giving him, is not known to the media as his predecessor managed to obtain it while was investigating undercover, but after he was discovered, he was killed. They found a video recording of his death in his eye socket. Naoto kept requesting transfers until he was finally transferred to his predecessor's position six months ago.

As Takemichi can't go back on any date he wants, Naoto tells him that when he gets back 12 years ago, he needs to meet the Tokyo Manji Gang top two members: Manjiro Sano and Tetta Kisaki. Naoto states that if those two never met, the current Tokyo Manji Gang would never exist and his sister wouldn't have to die. Takemichi wonders how he will go and Naoto mentions that Takemichi told him he went back in present after handshaking Naoto and he believes that's the trigger. Naoto informs Takemichi that Manjiro and Tetta met in August and he must stay close to one of them and prevent them from meeting. They shake hands and Takemichi time travels 12 years ago.

Takemichi ends up accidentally shaking Naoto's hand in the past and returns to the present. Naoto wonders if something changed, but gets angry learning it was an accident. However, he reveals they learned something new - if he spends a week in the past, he will also spend a week in the future and his body would remain in suspended animation. Takemichi reveals he met Manjiro Sano, making Naoto wonder why he didn't kill him and that if he could, he could have killed him himself. Takemichi suggest they go and see Manjiro as he wants to learn from him, why Toman changed.

Naoto agrees, stating that Takemichi's weak side seems gone. While they go over documents to look for a way to find Manjiro, Naoto sees someone he doesn't recognize. Atsushi Sendo had become a member of Toman's upper echelon. Naoto finds it strange as in his timeline, Atsushi got arrested for stabbing Masataka Kiyomizu and after his release he was just a no-name punk. They realize Takemichi must had changed the past after he met Manjiro and decide to call Atsushi as he may arrange a meeting with Manjiro. Takemichi manages to arrange a meeting, but Atsushi wishes to speak with Takemichi alone. Atsushi ends up killing himself and Takemichi tells Naoto to look into the day Ken Ryuguji died, as it was Tetta Kisaki who turned Toman evil. Takemichi then decides to save everyone.

## Moebius Arc

Takemichi returns to the present not believing that Manjiro and Ken would end up in a conflict and asks Naoto to track Nobutaka Osanai in order to ask him what happened between Toman and Moebius. Naoto tracks Nobutaka to a construction site. They end up seeing Nobutaka being yelled for being late and are surprised he used to be Moebius commander. They end up talking with him, and Nobutaka initially refuses to talk about Toman fight, however he denies Naoto's accusations that he ordered Ken's death. Nobutaka reveals that they didn't kill Ken, but the incident was a trigger that led to Toman's internal conflicts and all was planned by someone. As Nobutaka's boss calls him, Nobutaka leaves, stating that if Ken didn't die, his life won't have been ruined. Naoto believes Nobutaka, as he looked quite shaken and realizes that someone used Nobutaka and wished to split Toman. Takemichi then returns to the past, in order to warn Mikey.

As he manages to save Ken, Takemichi returns to the present. Naoto calls him stating that he managed to do it as Hinata is alive and invites him to go visit her. On their way, Takemichi changes his mind and decides to not see her and is fine just knowing that she is fine. He still ends up bumping into her at the building entrance and they end up in Hinata's apartment. As Takemichi and Hinata are embarrassed to talk, Naoto is annoyed by the awkwardness and decides to leave, but Takemichi begs him to stay. Naoto proposes they go out, hoping that things will change, but Takemichi and Hinata are still awkward towards each other. Naoto receives a call and is called at the police station. He leaves his car to Hinata and tells her that he will take it tomorrow.

A bit later Hinata is killed. At her funeral, Naoto is unable to hold his tears. A bit later, Naoto reveals that Atsushi's family is missing and he was likely forced to kill Hinata. Takemichi tells him that Atsushi's final words where the same as the last time, causing Naoto to lose hope that they can change the fate. Takemichi encourages him stating that not all is lost and he will become Toman's leader to save Hinata, but wonders what happened to Ken.

At October 20th, 2017, Naoto calls Takemichi to Tokyo's Detention Center. He explains that Ken is alive, but is on a death row. As they meet Ken, Takemichi realizes Ken haven't changed, but Tetta Kisaki had forced him to kill someone and originally Tetta loved Manjiro, but ended up hating him and wishing to take all he had. At his apartment, Naoto reveals that he doesn't have much information about Tetta, but he is the current leader of Toman and likely the one that keeps killing his sister. Naoto is surprised that Takemichi is serious about becoming Toman's leader, but agrees with his plan and they hake hands, sending Takemichi back in the past.
