Guruko

He has tan fur, a white snout, long ears that have a dark brown colour and noticeably more pronounced whiskers than the other ninken. He wears the standard outfit of Kakashi's ninken, which consists of a blue vest with the heno-heno-moheji seal and a Konoha forehead protector on his forehead.

In the anime, after they made a contract with Kakashi, Guruko 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.
