YOU need to complete all missions but of course you need to be all the ranks first finish the sasuke quest for power than the ranks are(genin,chunin,missing nin,jonin,nine tail fox,akatsuki,anbuandhokage)
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

An ak74U silenced SMG, instant unlock instead of having to level up. And a m1911 WWII pistol instant unlock. Instead of having to level up.

You would need a locksmith to unlock it for you, there is no real way to do it without having the key.
