Yukimaru is the leader of the Seven Samurai who helps and joins Fena in his quest. Yukimaru is an introverted and stoic individual. He is extremely protective of Fena Houtman, whom he has known since childhood. He also shows leadership towards his fellow samurai ninjas when they are together, even during combat. Although he has never been seen to smile before, his ears blush when teased about his apparent feelings for Fena. Although he feels that her protection is paramount, he is not afraid of death to protect her.
