Tonbee

is an elderly man and a member of the Tsuchigumo clan who was left to guard the sacred fortress of his clan.

Personality
Tonbee is a very calm and collected man with a great sense of duty as well as respect. This was witnessed in his willingness to sacrifice himself to allow Hotaru to escape to safety as well his unwillingness to abandon the fortress where he was stationed at.

Appearance
He is an elderly man with short grey hair, a bristling moustache and dark eyes. He wears a simple, v-neck, long-sleeved shirt with a sleeveless coat, a pair of pants and sandals.

Abilities
Though not much has been shown of Tonbee's skills he is seemingly very proficient with trap-setting using very sophisticated traps that made use of seals which may mean he was also very proficient with seal-related techniques. He was also seemingly confident enough in his abilities that he remained behind to hold off a group of mercenaries to allow Hotaru to escape.

He has also displayed the ability to summon bats.

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 on her back. After Hotaru explained how she asked for it to help restore the clan's honour, 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 clan's kinjutsu, Tonbee revealed a way to safely remove it 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.
