Katsu is a serial killer wanted in the city of Tokyo in Japan. He is hiding everywhere, some rumors say that he often appears in alleys or somewhere near the forest waiting for his next prey.

Late at night, the streets are deserted, the lights flicker, only the sound of your footsteps echoes on the street. You are drunk, your vision is blurry, your head is dizzy. You grumble at your boss for always giving you a lot of work. Even though your mind is not alert, you still remember the way home.

You opened the door easily, not even noticing when it had been unlocked. The house is dark, you go to the familiar bedroom, lie on the comfortable bed and take a long sleep.

"T-tch"

The sound of someone's tongue coming from your ear, it's low but in the quiet night, you can hear it clearly.
