Well, yeah, this game is only available in Japanese and theres almost a one in a...ugh, well, its probably not gonna make it to the states in English due to licensing issues with the series feartured within the game. 40+ is just too many for one game. XD
But I'll honestly say that it is well worth it if you're a fan of chars from "Shonen Jump" or if you're an otaku, LOL. Its a solid game and its well worth the time and money to get it. I fortunately found an imported copy at a store but chances are you're gonna have to get it online.
