Doujinn Ōtsutsuki

Doujinn Ōtsutsuki is the rebirth of Doujinn, who died from sealing his chakra in a temple.

Background
In his previous life, Doujinn was the Kage of Fubukigakure, which he went to deep measures to protect it. One fateful day, another Rinnegan user appeared, and attempted to take over the village. After the battle got intense, Doujinn decided to sacrfice himself, and did that by sealing every chakra inside of him into a temple, trapping the enemy forever. However, he was too strong, and Doujinn died in the process.
