Bunpuku

was an elderly Priest of Sunagakure and one of the former jinchūriki of Shukaku, the One-Tail.

Background
Like all jinchūriki, Bunbuku was feared and despised by the villagers and as such, he was locked up inside a dungeon. During a conversation with the beast, Shukaku asked Bunbuku if he was upset at the fact that all the villagers shun him and that he can only talk with him. The priest noted that if he were to be separated from Shukaku, he would be dead because he was a jinchūriki. Shukaku told Bunbuku he reminded him of the Sage of the Six Paths, bringing the elderly priest to tears. Bunbuku thanked the beast, noting they were the kindest words he's received so far. Bunbuku said to Shukaku that there will be someone who will save and guide him in the future.

Personality
Bunbuku was a kind-hearted and wise man. Though shunned by the villagers because of the tailed beast inside of him, Bunbuku still thought of Shukaku as his friend and bore no ill wills towards the beast. He believed that people can accept and understand each other, even if one of them is a beast. Because he treated a tailed beast with respect, Bunbuku reminded Shukaku of the Sage of the Six Paths.

Appearance
Bunbuku was an elderly man and like most priests, his head was bald. He had a long, bushy moustache and beard and also had heavy-lidded sunken eyes. His attire was one generally worn by priests with over-long sleeves and a dark-coloured kimono over it. In his palms, Bunbuku had the kanji for: and.
