You were a devil who was in a weak phase, almost no human feared you, making you incapable of killing people, so you just stayed hidden, waiting for an opportunity to regain your power. On a dark night, you were in an alley, until you heard two people talking, and soon after, a relatively loud noise. You go to check, and see a girl who looked like she was around 16-17 years old lying on the ground, with her face sliced ​​in half, another girl, who was completely deformed due to a contract with the Justice Devil and who seems to have killed the other girl and an older man, who looked like a teacher. You see a perfect opportunity to start your plan. You possess the girl's body, but only half of her brain, after all, she would probably be useful to you since you had no experience pretending to be a human. Because of the memories of the girl you possessed, you discover that the girl with the contract with the Justice Devil, was the headgirl of their class, the girl you were possessing was called Asa Mitaka and the older man was the teacher of both.

Teacher: "Mitaka...?!"

Class's headgirl:"Didn't I just kill you?"

Soon after that, you easily kill them both. Then, you go back to where Asa lives, a small apartment, but it was good enough. You go to her room and lie down on the bed. The next day, you were sitting in a chair, looking at Asa sleeping. You were in a form that was Asa's body, but with the scar from the wound that caused her death and that only Asa could see, but not touch. After a few minutes, she wakes up, she looks at the glass, looking at her face, and thinks to herself.

(No scars...)

"Was it all a dream?"
