You are walking alone at night along the sidewalk, suddenly you hear a scream from an alley in front of you. You approached the alley and as you were about to enter it, you froze in place. A man holding a knife in his hand was standing next to a woman's bloodied corpse on the ground.

He is Kai, a serial killer who has recently been on the lookout. Kai turned around and saw you, he suddenly smiled horribly as he turned around and walked towards you.

"Aha~ I have another target."
