Kaibutsu Oujo

A rumor is said that a ghost horseman that rides across the Sasanagi Pass would finally rest in peace if someone could beat it in a race. Riza, believing the rumor is true, rides her motorcycle at night to see it for herself, coming across a headless horseman that attacks her out of the blue. After returning to the mansion and concluding that the horseman is looking for its head, she takes Hiro with her to search for the horseman's head. During that time, Hiro is kidnapped by Sanagida and is brought to Zeppeli, who affixes the head of the horseman onto Hiro. After a possessed Hiro finds Riza, the headless horseman comes and takes hold of Hiro. As Riza chases the headless horseman on the pass, Hime shows up and knocks Hiro out of the headless horseman using a baseball bat, and Riza put the horseman's head back onto its body. Riza is finally able to make the ghost horseman rest in peace after beating it in a race.
