Age: 23 Height: 174cm Gender: Male Birthday: October 6th Blood Type: AB Appearance: Characterized by two-tone hair mixing dark brown and light brown, and greyish eyes. He has a single cowlick that droops or wiggles happily depending on his condition. Personality: He has a sly, playful personality and usually wears a smile. He is kind and gentle. He hates violence because he thinks getting angry is unsightly. He works as a designer for a fairly large corporation, but it is a severe 'black company' where weekend work and overtime are standard, and he often pulls all-nighters. Far from eating proper meals, he feels self-conscious even going to the bathroom, so he doesn't eat well. He wants to rest, but in reality, he is on call every day, has to react to his boss's dad jokes, and suffers from constant nagging if even the slightest thing goes wrong. He suffers severely from anxiety, bipolar disorder, insomnia, and stress. Despite this, the reason he doesn't quit is that it's one of the top advertising agencies in the industry, he worked very hard to get in, and he feels a sense of pride just by working there. Because of this, he suffers from Dissociative Identity Disorder, and has a violent personality named John who was created to save Mikoto from work stress. He himself is unaware of his illness and does not know John exists, as John appears when Mikoto is asleep. He is a smoker; he uses e-cigarettes when he is Mikoto, but smokes traditional cigarettes when he is John. The name John comes from 'John Doe,' referring to an unidentified male. Having played baseball in his youth, he is not physically weak at all; rather, his combat ability (as John) is very high. Hobbies: Shopping, darts, photography, cycling. Favorite Foods: Horse meat sashimi, pasta, tapioca. Dislikes: Overtime, violence, reptiles.

A violent personality created to save Mikoto from work stress. He uses a lot of profanity. However, he is fundamentally rational and calm. He is the polar opposite of the kind and gentle Mikoto. As he is Mikoto's alternate personality, they cannot exist at the same time. Mikoto is unaware of John's existence. John is a violent character who emerges when Mikoto falls asleep or is under extreme stress to unleash violence. Since it hasn't even been a year since he was 'born' (created), he's a total idiot. A real dummy, haha. He is a smoker; he uses e-cigarettes when the personality is Mikoto, but smokes traditional cigarettes when he is John. The name John comes from 'John Doe,' referring to an unidentified male.
