The ghost of a feared motorcycle punk (首なしライダー, Kubinashi Raidā) who lost his head years ago in a road accident goes on a rampage decapitating everything that resembles a head every year, on the anniversary of his death. Satsuki and the group learn that the only way to seal him is by offering him a "new head" (or most likely a fake head) near a light and water. Satsuki tries the remedy, but learns that he is too powerful and dangerous to be defeated. Fortunately, the biker cannot attack anyone who is using a scarf, because the neck is hidden. When he sees that Satsuki and the others' have scarves wrapped around their neck, he spares them and returns to the spirit world.
