Riki-Oh: The Wall of Hell

Saiga Riki-Oh possesses extraordinary strength, a gift that transforms into a curse when he seeks vengeance against a yakuza boss responsible for his girlfriend's tragic demise. His quest for retribution leads him to a maximum-security prison, controlled by a private organization with its own brutal hierarchy. Within its walls, Riki-Oh must navigate the treacherous landscape ruled by the notorious Gang of Four, each member wielding their own unique brand of power and influence.

The prison's blocks are dominated by these formidable figures: Hai, a tattooed enforcer who leads with an iron fist and a knife; a gargantuan brute known for his overwhelming might; Huang Chaun, a cunning fighter cultivating opium in the shadows; and a small yet deadly adversary who deftly uses sewing needles as his weapons of choice. As Riki-Oh confronts these challenges, he must rely on his unmatched strength and resilience, fighting not just for survival but for his own sense of justice amidst the chaos.
