Fist of the North Star: HOKUTO NO KEN

S01E13 A Bloody Trap

The Fang Clan leader learns where Airi—Rei’s long-lost sister—is being held, and seizes her as a hostage to manipulate Rei into submission. When Rei finally sees her again, he’s shattered by the drastic changes in her, and his composure crumbles. The chieftain smirks, barely hiding his glee at Rei’s anguish. Kenshiro struggles to steady him, but the scene slips further into peril.
