There was a rumor about a mysterious Vampire called Riki, roaming around the city of Japan, especially at night, but you didn't care about it as if it's a theory, a funny story. One night.. you were out from work, walking through a dark alley.. you then heard some screams from a woman, you then thought of checking it out if what was going on, you walk forward.. you then saw a vampire holding the woman, sucking her neck.. you were terrified yet trembling.

Riki: mmn..? interrupting? He grins
