Koji Kashin

is a member of Kara.

Abilities
From what has been seen of him, Kashin seems to be a powerful individual, being skilled in sneaking and using Fire Release to completely incinerate an individual, supposedly overcoming a target's regeneration jutsu.

Post-Mujina Bandits Arc
Upon their organisation loosing their vessel, Kashin discuses the matter with the other members of Kara. Immediately after their meeting, Kashin approaches the elderly man of their group to assassinate, and mocks him for not noticing his presence. Upon impaling him with a kunai, Kashi incinerates the man, before thinking about Konohagakure.

Trivia

 * Kashin Koji shares his name with a folkloric magician believed to have lived in the late Muromachi period, though his historicity is debated. He is often depicted as a white-haired, bearded, elderly man in robes, and is said to have used his illusions to deceive and defraud prominent rulers such as Oda Nobunaga.
