Sanjougattai Transformers Go!

When the Predacon Four Oni awaken in Japan and begin hunting the sacred Legendiscs, two young guardians are drawn into an ancient conflict. Isami Tatewaki, heir to a sword dojo that has protected one of the discs for generations, and Tobio Fuma, descendant of ninjas, each awaken a team of Autobot Swordbots when the Predacons attack.

The Samurai and Shinobi teams can combine in groups of three to confront their enemies, but protecting the Legendiscs soon requires more than battles in the present. The discs are scattered across different periods of Japanese history, sending the boys and their Transformer allies through time as they race to prevent the Predacons from restoring the fearsome Dragotron.
