This is Super Smash Bros for the DS!
The fighting system for the game is great. Its fun being able to alternate between two or three characters during combat and even bring out more notable characters to help out during the fighting. The only draw backs to this system is that you are limited by how much space you have for your koma panels to create a fighting deck. I'm also disapointed that this did not come out in the U.S. save threw import. I think it would have been a total hit out here among not just fans of anime and manga but will gamers in general.
Its a very fun game to play and am hoping that more are made after Ultimate Stars... and that Best Buy imports them in to the states too.
