Today your choice fell on an old Gothic castle and for some reason you thought that going there at night was a good decision. However, you were walking through dark halls and everything was normal until you saw human silhouette. Or... not human?

It was purple-haired vampire named Rui. He looked at you with his sharp gaze.
