15x2 - Kamen Rider

After rescuing Chizu, Hibiki spends the night at the memorial where Asumu is staying. The next day, Asumu meets Hibiki out by the beach and they discuss what Hibiki does for a living. As Hibiki searches the mountain, Asumu follows him and is attacked in the woods, where he is rescued and witnesses Hibiki transform to fight the Hime and her child, a demon-spider called Tsuchigumo.
