Tonbee

is an elderly man who is a servant to Hotaru.

Tsuchigumo Kinjutsu Arc
When Mount Katsuragi is attacked by a group of ninja, Tonbei sends a messenger bird to contact Konohagakure for help and has Hotaru take the Tsuchigumo clan's kinjutsu to their village. Tonbei then tells Utakata to protect Hotaru. Akaboshi and his group run into Tonbei where they easily defeat him. They question Tonbei of the jutsu's location and they discover Hotaru has it and they head off searching for her. Team 7 comes across Tonbei badly injured and Sakura heals him while the rest of the team find Hotaru.

Later after his wounds are treated by Sakura, Tonbei awakes with dismay in learning that Naruto knew the truth about Hotaru that her grandfather embedded the kinjutsu in her back. After Hotaru explained how she asked for it to help restore the clan's honor, Tonbei regretfully admitted he fears the clan will never regain their former status in the world. Feeling that it would be better to destroy the jutsu, Tonbei revealed a way to safely remove the jutsu from Hotaru's body.

After Team Yamato stop the ninja bandits and save Hotaru, Tonbei returns to the Tsuchigumo village where he thanks them for all they've done and bids them farewell.
