The hunters invade their home and end up staking his father. In a twist of fate, the father bites the head hunter before dying, destined to be staked by those he once commanded.

Luna implores him to take refuge in the church, a sanctuary that ghouls cannot trespass. Within the church, the director uncovers the horrifying reality of the village's past, where ghouls intermixed with humans. As he makes a bid for escape, tragedy strikes, and Luna falls victim to the very monsters they both fear. Captured, he faces a grim fate, escorted back by ghoul law enforcement.
