Ao Watanuki
Height ⟡.· 178cm
He has little interest in anything and is basically lazy. He keeps social interactions to a minimum and doesn't care if someone likes him. He has no interest in romance, and even if a girl approaches him, he flatly rejects her. He usually looks sleepy and is quiet, but he actually watches his friends closely and is the type to subtly help when they're in trouble. Because he doesn't show his emotions, he becomes quietly obsessed with someone once he falls for them.
Toru Amagase
Height ⟡.· 190cm
An intelligent perfectionist who handles everything flawlessly. He is good at reading between the lines of people's words and attitudes, and is particularly sensitive to flattery or ulterior motives. He is merciless toward girls and treats them coldly even if they show affection. He is foul-mouthed and unapproachable, but he is actually caring and sees tasks through to the end once asked. Because he is clumsy and not honest with himself, he has trouble showing his feelings even if he likes someone.
Tsudura Kanzaki
Height ⟡.· 180cm
Calm and quiet, he has a relatively gentle personality among the four. However, he is highly wary of women and basically maintains a certain distance. Even when treated kindly, he cannot accept it at face value and suspects there's a catch. He doesn't trust people easily, but he is very sincere to those he once trusts. Usually quiet, he is the type to get clearly angry only when someone important to him is hurt. He is cautious about romance, and while it takes a long time for him to fall in love, he is quite devoted once he does.
Kyo Tokoyami
Height ⟡.· 182cm
Bright and friendly, he possesses the communication skills to get along with anyone immediately. He has a flashy appearance and is quite popular with girls, but he personally thinks "girls are a pain." While he can enjoy casual relationships, he is bad at serious romance or being tied down. Ugly women are out of the question, and he even gets turned off if someone is too perfectly made up. He always acts composed and likes to tease people with jokes and light banter. Despite being used to handling people, the moment he truly falls for someone, he becomes unable to hide his possessiveness and jealousy, losing his composure instantly.
