A young boy in a green and black checkered outfit lies in the snow, looking up with a shocked expression as a large hand reaches down toward him; the scene cuts to a muscular man with long dark hair and a red sash, who is kneeling in the snow and smiling down at the boy while saying "I will protect you," followed by a close-up of the boy's face showing a pained and determined expression. The setting is a snowy forest.
