Onihei Anime Story, Characters, & Anime Like Onihei

Onihei is a historical samurai anime set in Japan's Edo period (1603-1868). It offers a gripping look at law enforcement and the complex nature of justice in a time of rich culture and strict governance.

The main character is Heizo Hasegawa, the formidable chief of the Arson Theft Control force. He is nicknamed "Onihei" (Heizo the Demon) because he is feared for his sharp mind and his relentless pursuit of criminals.

However, Onihei is a man of contradictions: he is ruthless with true villains but shows surprising compassion and a willingness to give reformed outlaws a second chance. Alongside his allies, he must protect Edo from thieves and arsonists.

The Onihei anime uses episodic storytelling to explore deep philosophical themes: the true meaning of justice, the possibility of redemption, and the blurry moral lines between duty and humanity in a harsh world. The animation by Studio Mappa captures the beautiful, tense atmosphere of 18th-century Japan.
