Tokio is a first-year middle school student who lives in modern-day Tokyo. One day, he is suddenly appointed to be a member of the 24th Century time and space management office. Through this, he learns something shocking!

The truth is, the history written in his school textbooks is all a lie - and the real history is far more interesting! So, alongside fellow team member Calen, Tokio ends up searching for the true history whilst commanding Bokan Mecha 24.

However, in their way stands Bimajo, Tsubuyakky, and Suzukky! Also known as Akudama, they are hired by the world’s biggest textbook company History Paradise and ordered to protect history as is written in the books.

What kind of new history will be discovered next?

Tokio

Voice Actor: Akihisa Wakayama

Scouted by JKK time and space management office due to his incredibly lax nature towards time (in other words, he’s always late.) He might seem like your typical kid nowadays, but he’s actually an honest, all-round good guy. Loves bugs.

Calen

Voice Actor: Akari Katou

Loves history, or rather loves cosplaying clothes from whatever era of history she’s in. A high school girl and Tokio’s upperclassman at JKK. Apparently she works there in order to find a certain someone...

Bimajo

Voice Actor: Eri Kitamura

The leader of the Akudama trio. A department chief… For now. Her age is… A mystery.

Tsubuyakky

Voice Actor: Hiroaki Hirata

In charge of mechanics. Your average employee. His hobby is tweeting online.

Suzukky

Voice Actor: Kenta Miyake

A trainee whose only redeeming feature is his incredible strength. Suzukky is a temporary name - because he’s only half-qualified, he hasn’t got an Akudama nickname like the other two.
