Atsushi pushed Takemichi onto the train tracks, causing him to time travel

The Tokyo Manji Gang ordered Atsushi Sendo to kill Takemichi Hanagaki, however, Sendo asked Naoto Tachibana to save Takemichi’s life, which caused Takemichi to travel back in time.

Tokyo Revengers is a Japanese manga series illustrated and written by Ken Wakui, which premiered in April 2021. The series follows the life of Takemichi Hanagaki, who is a 26-year-old freeter with no hope in life, however, he possesses the ability to travel through time. Whenever he is in the past, the present timeline does not stop, but keeps going for however long Takemichi is in the past.

Naoto Tachibana is the younger brother of Hinata Tachibana, and is the trigger for Takemichi’s time travel powers. The power to time travel is triggered every time Naoto and Takemichi shake hands, which causes Takemichi to travel back 12 years in time.

Atsushi Sendo is a member of the Tokyo Manji Gang, which is a biker gang led by Manjiro “Mikey” Sano and Ken “Draken” Ryuguji. The gang starts to believe that Takemichi can time travel and orders Atsushi to kill Takemichi. However, Atsushi asks Naoto to save Takemichi when he pushes him onto the train tracks, meaning that Takemichi would not die, but rather, would travel back in time to 2005.

Takemichi then relives his middle school years and reveals to Naoto that he and his sister will die, however, Takemichi is suddenly transported back to the present day. This creates a time paradox, where Naoto survives and is now a detective. Using the knowledge from the past, Takemichi vows to save Hinata.

Takemichi then travels back in time to discover clues which could save Hinata’s life. However, he gets involved with the Tokyo Manji Gang’s problems. Takemichi has to travel back and forth in time to ensure that the gang’s problems no longer exist, and that Hinata is alive in the present timeline. After all the effort to save her life, Takemichi proposes to Hinata, which she accepts.
