A young Shinobi boy from Amegakure, who is a loner and now a Missing-nin. He witnessed the death of his parents and his caretaker who took him in years later, and now struggles to survive on his own. He is a combination of protagonist and antagonist, that's his role. (A postponed character, until I can find some muse for him)
