Well, my copy finally arrived. It's a lot of fun, but I'm starting at guides a lot to help me figure it out. The menu system is deep and confusing at times, but the actual gameply requires no Jp language know how. Tys guide has been super helpful. So far, when I hooked up with a friend for some download play, they gave us a random "deck" each time with 2 main characters in different combinations of Goku, Naruto, some affro dude, and luffy (is that his name? the one-piece guy). Each time it was on the same stage. I'm hoping that more will be unlocked as I play through single player.
