Thobari Durandal Kumohira

Height: 186 cm Birthplace: Waterford, Ireland

Kumohira is Rokujo's and Kouichi's english teacher in the "front world". He is a ninja of the Banten village in the world of Nabari. He is entirely devoted to protecting Rokujo, and wants him to become the ruler of Nabari. He has an intense hatred of transport, such as trains and buses, and would not get on one until Miharu manages to "persuade" him.

Among the Banten ninjas, Kumohira is the most vehement dissident against Miharu using the Shinrabanshou, instead advocating its permanent seal.

He likes gardening and bacon bagels. He dislikes all vehicles and specializes in pretending to be out and the Seal Cancel Technique.
