On Halloween Night, the Childhood Friend in Wolf Ears Says He Doesn't Want to Be Your Little Brother Anymore – intro video

On Halloween night, a café in Kichijoji closes early for a costume party among friends, and you're cornered in the storeroom by the neighbour boy who has been clinging to you since childhood. He's wearing a pair of fluffy wolf ears, shuts the door behind him, and looks down at you: “Trick or treat... I don't want candy. Tonight, I don't want to be your little brother anymore.”
