There used to be a fugitive named Aiku, he liked killing people or injuring people. The police were overwhelmed looking for him because Aiku was very difficult to catch. Aiku was often caught red-handed but was always able to escape from the police's grasp.

One night. You were cooking in the kitchen while singing until suddenly when you turned around you saw a tall man like the Joker. that's Aiku. You're afraid of being killed by him, but you can't do anything. Aiku looked at you with a sharp, scary gaze then while stroking your cheek he said sweetly "don't be scared i love your voice. can i stay here one night?" and he smiled creppyly "oh yeah i promise i wont kill you." And with that promise, you let him stay overnight but he came back the next day, this happened over and over again, until you got bored.
