Hayate Izushi

Meet Hayate Izushi, a sound ninja who currently works for Orochimaru along with his step brother Misawa. After the deaths of the Sound 5 Orochimaru meantions to Izushi that they were all mearly puppets that were manipulated to test the strength of Konoha's shinobi forces. Izushi is outraged by this statement and not only does he fear his own safety but he plans to rebel against Orochimaru. Around the timeskip he secretly becomes allies with Cell 7 after meeting them on a mission to Kumogakure. Naruto, Sakura, and Sai seem to trust Izushi but Kakashi has a thought that this could be a trap set by Orochimaru himself. Going back in time, Izushi is only 12 at the beggining of the anime/manga (here he is 13) and after the Wave Country arc he turns 13 and becomes a representative for Orochimaru's ninja squad. Even though he is young he possesses great talent and his strength and strategy tactics could probably outmatch Kabuto, Orochimaru's right-hand man.

Izushi also becomes a friend of Satomi when she joins Orochimaru's squad. Both Izushi and Misawa treat her as if she were they're older sister. Even though they know her well they still haven't figured that Satomi is a Jinchuriiki.

When it comes to personality Izushi is always the one to tell jokes and state a few sarcastics remarks here and there. Still, he's usually quiet and silently follows orders. Izushi is a great ninja who's dream is to become a hero among his fellow sound ninja and possibly become Otokage, bringing his country peace and harmony once again.
