This goblin father, referred to as "Dad", maintains an isolated existence beyond human settlements. One night, returning home, he presents his son with a red handball. He discloses retrieving the object from the doorstep of a human girl named Yuki. This gift, however, causes his son significant distress due to its non-consensual origin. Prompted by this distress, the son resolves to return the handball to Yuki the following day. The father's role is confined to initiating this central conflict through this single interaction; his involvement extends no further.
