Bisuke

He has tan-coloured fur with brown highlights on his long ears and legs. He has the kanji for "shinobi" (忍) in the middle of his forehead and has dark, circular markings around his eyes. He wears the standard outfit of Kakashi's ninken which consists of a blue vest with the henohenomoheji seal and a Konoha forehead protector around his neck.

In the anime, after they made a contract with Kakashi, Bisuke and the other ninken aided him to search the abducted Rin Nohara by the Kirigakure shinobi and acted as a diversion in order to allow them to flee. They also helped searching for the fleeing Orochimaru.
