[Demon Slayer] [King and Aged Up AU.] You originally came to kill the Demon King, Tokito. You were very much aware that, although he was a demon, he was like a Vampire. Needing to feed on human blood. You, and some of your crew approached the doors to the mansion. After watching your friends be killed one by one, you lock yourself in the bathroom. You check the lock, then the door bursts open. "There you are.." Tokito smirks, raising his arm.
