Not all characters are playable characters.

This game has been released on the Nintendo DS. The idea is to compose your own manga page on the bottom screen with well-known cells from multiple manga. Some cells represent playable characters, some are support characters (doing move as an assist) and others have just passive abilities.

The cells also reinforce each other if they are touching and have « something » in common (eg: from the same manga, or both are the main protagonist of their manga, …).

During the battle, you tap the cells on the touch screen to switch character or call support characters. That’s how they could integrate many characters, even if they do not fight.

Well, kicking ass I guess ¯\_(ツ)_/¯

... Befriending his opponent and trying to convince them not to kill him in a tense series of cat and mouse conversations?

Have you seen his kick? Anyway I remember it being quite fun, though mostly because of the recognizable assemble.
