In the opening sequence, Hung Hei-Kwun asks his son - who is too young to understand - to choose between his favorite toy and a sword. If the child chooses the toy, Hung will send the son to his mother in heaven. In the first Lone Wolf & Cub / Baby Cart movie, Ogami Itto asks his son - who is also too young to understand - to choose between a ball and a sword. In both movies, the boy chooses the sword and lives.
