Seeking to understand why he couldn't capture a hauntingly beautiful young girl on film, Kouhei Morioka stumbles into a medieval castle and a world he cannot comprehend.

Elfriede, a servant of Count Kinkel, has come to retrieve Hazuki and return her to the castle. The little vampire proves to be less than agreeable, and a fierce and furry battle begins.

Kouhei's intense training in the mystical arts pays off. When Hazuki is set upon by a demon up on the mountain heights, it's the servant to the rescue.

Hazuki and Hikaru rush unheeding into the arms of the enemy, and Yayoi and Seiji hurry to their aid. Kouhei is at the mercy of the child vampire, as the defender of the mountain watches from the forest.
