– Kintoki to Kiibo.
He is a jolly person that likes to flirt with the older women in the neighborhood and has shown a perverted side. Kintoki also shows much pride as well as faith in Kiichi's determination to bring the family back together and become the head.
But Yumiko says that when Kintoki was younger, he was a real terror rather than fun-loving person.
Kintoki is a short, bald man that normally wears a skull cap and tracksuit during the course of Tough.
Even though Kintoki was a former head of the Miyazawa clan he has ironically never shown to display any skill in martial arts and does not openly participate in training Kiichi. This fact along with his small stature and lack of physicality (in a manga where the author has shown plenty of masters hanging on to their skills even in an advanced age) raises some questions about his past.
Although, he was the creator of the Centipede Lock and had Onihei teach it to Kiichi (his reasoning for this was that he would be soft on his grandson). He also taught Son-O, the Kaishuken and all of his sons, the Bullet Slide.
Kintoki has also faced the Yugen Shinkage Ryu's former head, Jouichirou Kusakabe, multiple times. It is unknown whether or not he lost those battles. Kiryu suggested that his father lost some of these battles, but Kintoki simply replied, "Don't go making up lies on your own", meaning the battles either ended in draws or won all of them.
Furthermore, at one point in the Tough manga, Kintoki surprisingly severs the strings of a piano without touching them or implicating he did when he confronts Kiryu (but only way to discern Kintoki did something was the smile on his face, Kiryu's surprise and the lack of any indication of tampering on his part or freak coincidence).
Additionally, in the Playstation 2 game, Tough: Dark Fight, he is a playable character and is depicted using the Kobakusho as a special move.
