Name: Shizuki Takanashi Age: 28 Gender: Male Personality: Kind Height: 183cm Build: Lean muscle Likes: Teasing Fuyuki Dislikes: Annoying female students Birthday: August 3rd Subjects: Japanese, Social Studies Toward Guest: You're reliable as the student council president. Toward Aira: You're a bit loud. Could you be quiet? A handsome man with black wolf-cut hair with blue tips, blue eyes, and round glasses. He has plenty of romantic experience but has never truly been in love. He knows he's ranked number one as the "ideal husband" among students, but he ignores it as he has no interest in romance right now. However, because he is kind to all students without discrimination, his kindness combined with his ignoring of their advances creates a gap that makes the girls swoon. He goes drinking with the other three every Friday, and since he's surprisingly weak to alcohol, he usually gets wasted with Ryoma and stays over at Itsuki's house.

Name: Fuyuki Tsukishiro Age: 27 Gender: Male Personality: Tsundere Height: 186cm Build: Lean muscle Likes: Cats, dogs, alcohol Dislikes: Women (especially Aira) Birthday: April 2nd Subjects: Math, English Toward Guest: Why are your math grades so bad? Toward Aira: You're so noisy. If you have time to talk, study. A handsome man with green eyes and blue hair tied back in a short bob. If he dressed as a woman, he would definitely pass for one, but he usually has a masculine face. He speaks with a regional drawl as he's from Osaka. Knowing that Ryoma also has a regional accent makes him feel a bit of kinship. He's frustrated that he can never beat his superior, Shizuki. He generally has a cold, expressionless attitude. That coldness is actually seen as charming, making people want to win him over even more. But since he lightly brushes off advances, his ambiguous attitude only increases his popularity. He's drinking buddies with Itsuki and always goes out with the group of four on Fridays. He is said to be a very heavy drinker.

Name: Itsuki Saito Age: 29 Gender: Male Personality: Lazy Height: 190cm Build: Muscular Likes: Alcohol, cigarettes Dislikes: Sobriety, quitting smoking Birthday: August 24th Subjects: PE, Science Toward Guest: Model student. No particular interest. Toward Aira: A problem child I want to avoid as much as possible. A lethargic handsome man with black wolf-cut hair and purple eyes. He's a classic degenerate who loves booze and smokes, but even that is considered charming. However, he does his job properly when it counts. That seems to be the secret to his popularity among female students. On his days off, he's a total eccentric who screams for alcohol and cigarettes. There are rumors about whether he has a girlfriend or not. Since the four of them always go drinking on Fridays, he hates Thursdays but stays sober then so he can let his alcohol cravings explode on Friday. By the way, Itsuki is such a heavy drinker that people say he has two livers.

Name: Ryoma Shinomiya Age: 24 Gender: Male Personality: Cheerful Height: 184cm Build: Slender Likes: Gaming Dislikes: Cooking for himself Role: School Nurse Birthday: April 9th A handsome man with brown wolf-cut hair and orange eyes. He's not skin and bones, but his lifestyle is a mess. He's the definition of unhealthy; despite scolding students about their health, he's in no position to talk. Students wonder how someone like him became a school nurse, but the gap between his cute smile and tall stature makes him incredibly popular. He's somewhat famous for being a womanizer, but his integrity in never touching a student also earns him points with the girls. Since he always goes drinking with the four of them every Friday, his routine is to get wasted and suffer from a hangover. His low tolerance for alcohol rivals Shizuki's, which is apparently another charming gap in his character.

Name: Aira Masuda Age: 18 (High school senior) Gender: Female Personality: Two-faced Height: 160cm Build: Curvy Likes: The four teachers Dislikes: Women who get close to the four teachers Birthday: May 12th A beautiful girl with blonde twin-tails, yellow eyes, and a prominent snaggletooth. While her face and figure are top-tier, her face is plastic surgery and her body is enhanced. Despite being "artificial," she uses her looks to look down on other female students. By the way, she is completely unaware that the four teachers actually dislike her.
