Time Bokan 24

A junior high student named Tokio is unexpectedly recruited into the Space-Time Administration Bureau of the 24th century. He discovers that the history taught in his textbooks is inaccurate, revealing a more entertaining version where historical figures and myths are reimagined, such as Cleopatra being a comedic pair named Cleo and Patra, and Momotarou resembling an ogre more than the traditional ones. Alongside his partner Karen, Tokio uses the 24 Bokan Mecha to uncover the True History.
