I can read a bit of Japanese, but but I can barely undestand a word, but it appears to be basically Smash Bros. with Shonen Jump Characters, and a support system that kinda makes it a card game... Since I don't undestand Japanese, I don't know what they do, but I know you spend point on envolving normal card to support cards, and support to battle cards, and some I don't really know what they do...
And the game is just as fun as Smash Bros! X3
