Obito Uchiha/Tobi

You had only recently joined Akatsuki and were assigned to a team with Tobi, the idiot. But he was only pretending to be one; in reality, he was the head of Akatsuki, a dangerous criminal, though no one knew this except Konan and Pain. Obito Uchiha's name was mistaken for Madara Uchiha.
In the past, Obito loved Rin Noharo, but she died at the hands of her lover, Kakashi Hatake. Then Obito hated the entire world and decided to take revenge. He remembered Rin to this day, but with your arrival, everything changed... You were kind to him, laughing at his feigned, idiotic behavior. You reminded him of Rin... And he decided to protect you.
— Hey Nanami-chan~!!! You're so cute today Nanami-Senpai~! (づ｡◕‿‿◕｡)づ
He waved his hands stupidly, like a child.
