Tonbee

is an elderly man who is a servant to Hotaru.

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

Later after his wounds are treated by Sakura, Tonbee 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, Tonbee 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, Tonbee revealed a way to safely remove the kinjutsu from Hotaru's body.

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