Timeline

An in-universe timeline is created whenever Takemichi Hanagaki travels to the present to see the changes he has caused through his time leaps. The first recorded timeline was the original universe in the beginning of the story, where Takemichi first learned about the Tokyo Manji Gang dispute that took the lives of Hinata and Naoto Tachibana.

Events with date approximations are denoted by "c." (circa) based on the currently available information provided by the anime and manga series. Therefore, they shall not be considered official dates for they are subject to change once new information is given. For the sake of clarity, this approximation system will be observed throughout the timeline of events.

Trivia

 * Emma's birthday was confirmed to fall on November 25, 1991, per the Official Character Book. However, Takemichi traveled to the present a week earlier, on November 18, during his 12th time leap, which goes beyond the theory that his time leaping ability can only take him exactly twelve years back and forth through time.
