Image Compliments of Yudetamago
Even if you do not read Japanese, the action is pretty straightforward and easy to follow. The artwork and character design for the baddie Thunder is super sick, and I am totally digging the Kevin Mask x Mantaro tag team. If Japanese is your thing, the storyline is solid, and you will not be disappointed.
