There's nothing special about this game, however I think that if you're a fan of anime then you may enjoy this game.
First let me talk about the multiplayer. I have never played it. And i never will play it. The game isnt very good to begin with, but the fact that you have to pay so many fees just to play this online (xbox live + separate fee for this game!) makes it absolutely unworthy.
Now the single player. You get all the xbox 360 achievements from single player, if your into that kinda stuff. It follows a simple pattern of going through "chapters" where you meet people, etc. The story is ok but not memorable or anything.
The gameplay is really lacking. Basically its a very slow progressing '2 button mashing' game. You have your basic attack with all different weapons. then you have another button for a "more powerful" special attack. The gameplay is simple enough, but i find it very annoying when you want to switch between weapons or just use items, its time consuming and unnecessary. There is no way to pause either.
So thats it. Not a very good game, but if you play a lot of games or like RPG's and want to try one out for the 360, then give this game a try. Your better off spending time playing Oblivion or something better though.
