Tokio and fellow bureau member Calen use the Bokan Mecha 24, a machine which can transform and merge into various forms, to search for true history.
Tokio learns that, in reality, the history written in textbooks is all a lie and that the true history of the world contains amusing facts that remain hidden.
For example, the beautiful woman known in history as Cleopatra is actually a stand-up comedy duo named Cleo and Patra.
Tokio and his friends must face three evils familiar to the Time Bokan series, Bimajo, Tsubuyakky, and Suzukky.
