Answer 1

Answer 2

You have to do the missions in order to unlock characters. There are no cheats or hacks for Naruto-Arena. The people you see using Atkatsuki members as Academy Students are players who reset their accounts, which deletes all previous matches and resets you rank, but you keep your characters.

I don't know how to use cheat engine, but that's how to do it without doing missions
