ONIHEI HANKACHO

Based on a series of Japanese historical novels, Onihei Hankacho is about Heizo Hasegawa, the illegitimate and only son of the head of special police in Edo. Heizo faces resentment from his stepmother, so he runs away from home, becoming the head of a street gang and leading a fast life.
But when his father dies, Heizo realizes his father’s commitment to fighting crime and goes on to lead a band of samurai police and reformed criminal informants to solve difficult crimes. His actions cause a villain to nickname him Onihei, meaning Heizo, the demon.
While he was called a demon and feared, he was forgiving and merciful to those who committed a crime out of necessity even if they were criminals. Heizo even dedicated himself to establish and maintain a vocational training school for criminals.
