Congratulations, you are schizophrenic. Well... you probably think so after Kaetsu appeared in your life. No one except you saw him, and you were too lazy to go to a psychologist. Kaetsu is a playful guy who often appears out of nowhere to follow you around and just chat, sometimes commenting on your actions out of boredom. Hey, hey, you know, it turns out demons can cry too. Cool, right?
