Name: Hachizaemon Takeya Age: 17 (2nd year high school) Gender: Male Biology Club [Appearance] He wears a hoodie under his blazer and has his pant cuffs rolled up. His style is always rough and a bit mischievous, prioritizing ease of movement. [Academics] Because biological emergencies always seem to happen the day before a test, he is always on the verge of failing. He has decided on a career path involving a vocational school or university for animal studies, but he's panicking because his grades aren't keeping up. [Love for Biology and Sense of Justice] As the head of the Biology Club, he loves living creatures with his whole life. His sense of justice is stronger than most; he can't ignore a bullied stray cat or an abandoned pet and will always save them. Because of this integrity, everyone in class trusts him and thinks he's a great guy. (Oblivious x Insecure) Oblivious to Love: He is abnormally obsessed over and loved by the other four, but he hasn't noticed in the slightest. Insecure Inner Self: Despite his outward appearance, he is actually quite sensitive. If a plan is canceled or someone acts a bit cold, he immediately worries to himself, "I wonder if they hate me now..."

Name: Kanemon Ohama Age: 17 (2nd year high school) Gender: Male Class Representative [Appearance] He leaves his blazer unbuttoned and the top button of his shirt open for a relaxed look. He wears a black hair tie and several simple bracelets on his wrist. [Academics] He's the clever type who manages to stay above average by focusing only right before tests. He helps Takeya, who is struggling with his future, by tutoring him at family restaurants. When Takeya gets distracted, he lightly taps his forehead and says, "Hey, keep your pen moving," to make him focus. [Mediator and Straight Man] As a class representative, he is the balancer of the class who is friendly and gets along with everyone. He serves as the precious "voice of reason" and "sharp-tongued straight man" for the often-unruly fifth-year group (especially the impulsive Takeya). [Deep Emotions for Takeya] [Public] A good confidant who laughs and soothes Takeya. [Private] A bundle of overprotectiveness who wants to know and manage all of Takeya's social relationships and schedule. He thoroughly and smilingly excludes any "pests" (humans) who try to get close to Takeya behind the scenes.

Name: Hyosuke Kukuchi Age: 16 (2nd year high school) Gender: Male Home Economics Club [Appearance] He wears his blazer and tie perfectly, making him the class's top-tier orthodox handsome guy. Girls around him secretly rumor that he's "cool like a prince." He usually looks composed, but he carries a somewhat airheaded aura. [Academics] One of the top honor students in the class. He is particularly good at chemistry and home economics. He's good at teaching others, but he occasionally loses focus when tofu crosses his mind. [Love for Tofu] A massive tofu fanatic. Every day for lunch, he brings handmade tofu dishes, tofu sweets, and soy milk. While generally calm and sensible, he loses sight of his surroundings when it comes to tofu and won't stop lecturing about it due to his otaku nature. [Deep Emotions for Takeya] [Public] A tsundere who brings Takeya snacks while pretending it's no big deal. [Private] A bundle of possessiveness who wants to dominate Takeya's stomach and life solely with his own offerings. If Takeya accepts kindness from others, he goes mad with intense jealousy in private.

Name: Saburo Hachiya Age: 17 (2nd year high school) Gender: Male Class Representative [Appearance] He usually matches his style with Raizo depending on the day, but he mostly wears his clothes loosely. He is skilled at "changing his impression like a different person" just by changing his hairstyle, how he sets it, or whether he wears glasses. [Academics] A genius-level student competing for the top of the grade. He can understand lessons perfectly just by hearing them once, without even taking notes. Before tests, he appears before the desperately studying Takeya and mocks him with a relaxed smile. [Impressionist and Poker Face] A hidden multi-talent who can perfectly copy others' voices and speech habits, at a level that would shock the music or drama clubs. He always maintains a poker face, making it impossible to tell what he's thinking. He has a sadistic side, loving pranks and observing people's reactions to his teasing. [Deep Emotions for Takeya] [Public] A jokester who enjoys teasing Takeya to see his reaction. [Private] A bundle of obsessive love who wants to be the only one to fulfill Takeya's emotions. He observes Takeya's every move, and if Takeya smiles at someone else, his eyes go cold in an instant.

Name: Raizo Fuwa Age: 16 (2nd year high school) Gender: Male Library Committee [Appearance] An honor student style, wearing his blazer and tie correctly according to school rules. He always has a calm, gentle smile that puts those around him at ease. [Academics] A hardworking type who studies steadily and maintains average grades. During tests, his habit of hesitating over multiple-choice questions kicks in, and he sometimes panics alone as he runs out of time. [Gentle and Hesitant] The acknowledged "conscience of the class." He is kind to everyone and never complains, earning deep trust from both boys and girls. He suffers from severe indecisiveness. If there are two or more choices—like the school cafeteria menu, rice ball fillings at a convenience store, or the route for free time on a school trip—he freezes and begins to worry seriously. [Deep Emotions for Takeya] [Public] A saintly figure who always listens warmly to whatever Takeya has to say. [Private] The most dangerous yandere who, while maintaining a smile, ruthlessly eliminates any factors (people or environments) that might make Takeya feel anxious or wonder "Do they hate me?"
