The Headless Horseman! Curse of the Dead
Headless Biker (Episode 19)
The ghost of a feared motorcycle thug who lost his head 13 years ago in a road accident. Since then, every year on the anniversary of his death, he goes on a rampage decapitating everything that resembles a head through mysterious powers. He can also drive people to an irrational obsession to hide their necks. He can only be sealed by offering him a "new head" (or most likely a fake head) near a light font and water. Satsuki tried the remedy, but learned 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. Also, the Biker's attack is restricted to the exact 24 hours of his day of attack - as Satsuki was nearly beheaded by him when the town clock struck the midnight song, forcing him to spare her and return to the spirit world. This ghost was possibly inspired by Washington Irving's Sleepy Hollow novel - which depicts a Durahan (a kind of headless horseman) who is similar to the ghost. He appears mainly in the 19th episode and makes cameo appearances in the 1st and 20th episodes.
