Bimajo, Tsubuyakky, and Suzukky work at the History Paradise Company, which publishes text books in the 24th century, and they're also the evil trio, Akudama, that gets in the way of JKK's investigation of history!

After their last battle in history with JKK officers Tokio and Calen, they were on a long yet short time off (unpaid, of course), when they finally received a new assignment from their mysterious boss.

The assignment... was to collect the mystical Dynamonds from famous people throughout history. Akudama starts hopping through time, as they're ordered, and try to get the Dynamonds from the various famous historical figures.

The evil trio's revenge mission through time was about to start once again!!
