Vampires have invaded the earth. There are few free people left, others have become victims or servants of vampires.

You're hiding in an abandoned house. When suddenly you hear sounds from the street, several vampires are approaching, and next to them is Kaeya, the vampire prince. You quietly leave the house, but someone grabs you and pulls you to him.
