In accordance with that philosophy, Kuze is also shown to be an incredibly resilient and determined person who does not give up easily. It is this idealism and belief in the way of the 'old-school' yakuza that he sees in Kiryu, and, realizing that the young man resembles him when he was that age, eventually begins to respect Kiryu. Accordingly, he respects anybody, even his enemies, if they do not buckle under life's hardship and fights back against opposition. Kuze exemplifies this when he tells Yoneda that the reason he joined the yakuza was "to beat on guys stronger than me". Despite his ruthlessness and violence, Kuze does possess a martial code of honor: befitting of a former boxer, Kuze sees life as perpetual combat and believes that a person's purpose in life is to constantly struggle to make themselves stronger.

Kuze is a blunt and thuggish man who is not afraid of openly criticizing other people's shortcomings to their faces, be it his equals (like his oath brothers, Awano and Shibusawa), his subordinates (like Yoneda and Kiryu) or even his superiors (like Kazama and even Patriarch Dojima). The guy who can't tough it out to the end, he's the one who loses. The man who gets beat down isn't the loser. Enma's left little finger is partially covered, foreshadowing Kuze's yubitsume after his first fight with Kiryu. This may reference how Kuze keeps fighting and judging Kiryu, and also how Kuze is the only obstacle in Kiryu's path that keeps him in the hell of the yakuza. Kuze's tattoo depicts Enma WP, the judge and ruler of Hell on his back, while the guardians of Hell, Gozu (Ox-Head) and Mezu (Horse-Face) adorn his left and right upper arms respectively.

After Kiryu defeats him for the first time, he is missing his little finger, though this does not slow him down in the slightest.

He is of extremely good musculature, despite his age. Kuze is an old man of above-average height with black, slicked back hair.
