Gaku Inuzuka

is a jōnin from Konohagakure's Inuzuka clan.

Background
Gaku, his ninken, Dōtō Akimichi and a fourth shinobi were part of a team which was led by Minato Namikaze during a conflict with Kumogakure. In his team, Gaku was responsible for short-range combat. In one of the battles, his team clashed with Kumogakure's A–B Combo. During Minato's fight with A and Killer B, Gaku expressed his shock over the latter's jinchūriki transformation. Directly afterwards, Gaku and his comrades received a signal to retreat, leading him to inform Minato that they are pulling back for the moment.

Personality
As the eldest of his team, he thought of Minato as a younger brother.

Appearance
Gaku is dressed in the usual Konohagakure flak jacket and has the distinctive Inuzuka's fang markings on his cheeks. He has swept-back brown hair with a beard of the same colour and black eyes.

Abilities
Gaku served as the short-range combat shinobi of his platoon. Therefore, it is very likely that he uses the Inuzuka clan's assorted techniques alongside his large-breed ninken.
