Synopsis
A retelling of the prison storyline from the manga RIKI-OH! The narrative centers on Saiga Riki-Oh, a young man endowed with superhuman strength. After exacting revenge on a yakuza boss responsible for his girlfriend's death, he ends up incarcerated in a maximum-security prison operated by a private organization. The facility is split into four blocks, each overseen by one of the prisoners known as the Gang of Four. The first is a tattooed knife-wielder named Hai, who runs his block like a mafia-style family. The second is a hulking brute (called Tarzan in the live-action adaptation) of immense power. The third is an effeminate fighter named Huang Chaun, who cultivates opium within the prison. The final member is a small man who wields sewing needles as his weapons.
