– Seiko to Kano's school teacher.
Stern but caring, Kiichi’s father Seiko is the current head of the underground murderous fighting school Nanshin Shadow Style. His unrivalled strength combined with his gentle nature and wisdom have earned him the nickname "The Quiet Tiger".
Seiko is revealed to be a very strict yet caring person, to his son at least, as he is very strict on Kiichi's training, not helping him with his ailment, and yet had helped him achieve the secret technique, fist of Bodhisattva. Seiko deeply loves his son Kiichi, and trains him harshly to prepare him for the hardships he will face as the next head of Nanshin Shadow Style.
Seiko has a buzz cut, having a full head of hair on top, and showing much skin on the side of his head. He is usually seen wearing casual clothing, and may sometimes go topless, during times of training with his son. He is also seen, when going out, wearing a black business suit, coming with a black tie, buttoned up white shirt and dress shoes.
Seiko had once faced against Kiba, in a death match with him. Seiko had suffered from major injuries, but in the end he had won against Kiba, costing Kiba an eye in the process, making Kiba very angry and obsessive over beating the Nadashinkage-ryu.

Seiko told Kiichi about the technique Goji used, a technique that would kill him in three years, telling him Goji is far more dangerous knowing the human body pressure points.
Seiko then went to the hospital, to find his son hurt in bed. He uses oriental medicine which healed Kiichi, hitting Kiichi's vertebrate. He then carried his unconscious son from the hospital, to the Miyazawa residence, where he told Kiichi to hit him with his Hashin Sho.

Seiko then hears Kiba's proclamation of having his wrestling go up against the Nadashinkage to which Kiichi accepted.
