"Tokyo Revengers" depicts the cyclical nature of history and the repetition of past mistakes through its main plotline, which involves time travel. The protagonist, Takemichi, has the ability to go back in time to his middle school days in order to prevent tragic events from happening in the future. However, he often finds himself facing similar challenges and conflicts in each time loop, highlighting how history repeats itself and how individuals may unknowingly make the same mistakes over and over again. Through Takemichi's journey, the anime illustrates the idea that without conscious effort and change, history is doomed to repeat itself.
