Meanwhile, Casshan reached his castle and defeated a squad of suicide robots while Friender sacrificed himself during the battle. Casshan survives a MF pistol shot from a female robot commander who realized he was something more than a human or a machine. Casshan then entered the castle and engaged the Black King but struggled.
