Mitsuo

was a follower of Hagoromo Ōtsutsuki.

Background
In the days following the battle Kaguya Ōtsutsuki and the Ten-Tails, Mitsuo took residence near one of many destroyed bridges. He would claim to aid travellers to cross the bridge, only to rob them. One day, Hagoromo and Futami came by. Mitsuo began talking them up, before recognising Futami, who he knew as a fellow thief. Angered at the perceived intrusion on his territory, Mitsuo began to argue with Futami, only to discover he was no longer a thief, and that he and Hagoromo intended to rebuild the bridge. The same change that happened to Futami happened to Mitsuo, who became the second of Hagoromo's many Ninshū followers.
