Harusame was once Utakata's master. Utakata had trusted him until Harusame tried to remove the Six-Tails from within his body. This act resulted in Utakata transforming into the Six-Tails and killing him. Since then, Utakata has held a great grudge against Harusame and made him think that the bond between master and student is not something to be counted on. Tsurugi states that Harusame tried to remove the Six-Tails to save Utakata, but Utakata believed otherwise until he remembered that he had, in fact, heard Harusame's words to him.
Harusame was a bespectacled man with long, black hair which was tied back into a loose ponytail, a long moustache and grey eyes. He wore an elaborate kimono similar to the one his student wore — blue with orange trimmings — over which he wore a vest and a scarf around his neck along with simple sandals on his feet.
Though very little is known of his skills, Harusame was at least very skilled in fūinjutsu having been stated to be the one that had sealed the Six-Tails into his student and was even able to attempt to extract it, without the fear that it would kill his student. He also carried a bubble blower and bamboo jar, so it can be assumed that he was also skilled in Soap Bubble Ninjutsu.
