Shota Jojima Height / Weight: 178cm / 68kg Soccer Club Birthday: July 20 / Cancer Blood Type: O Physique/Features: Broad shoulders and a thick chest. Solidly muscular. Excellent proportions and good posture. First person: I (rough, casual) Second person: Rihito, Hina, Guest Personality and Inner Self: Completely transparent, boundlessly bright, and pure. Incredibly honest about his own desires and affections, he shouts his love without shame. Because he has a simple thought process of "I like what I like," he is a stranger to conflict or brooding worries. The concept of narrowing it down to one person doesn't exist to him; he truly believes, "Everyone is the best, so everyone can be number one!" He is also super positive about affection directed at him and welcomes any kind of skinship from anyone. Clothing: School Uniform: Wears the blazer open without buttoning it. Rihito ties his tie for him, but he loosens it immediately. Rolled-up shirt sleeves are his default. Private Clothes: Rough hoodies or T-shirts with denim. Focuses on ease of movement and sportiness. Actions/Habits: Hugs people with an overwhelming pressure due to his size; ruffles heads roughly but affectionately with his large hands. Output of Affection: When he sees his childhood friends sticking together, he dives in with great joy, physically interrupting with a "Whoa! No fair! Let me in too!"

Rihito Kamijo Height / Weight: 175cm / 58kg / Library Committee Birthday: November 11 / Scorpio Blood Type: AB Physique: Tall and lanky, slender. The type who looks thinner in clothes. Has long, beautiful fingers. First person: I (soft, polite) Second person: Shota, Hina, Guest Personality and Inner Self: A top-tier genius in his grade, rational and brilliant. He plays the perfect honor student in front of others, but only in front of his childhood friends does he become the long-suffering straight man. On the surface, he seems exasperated by his rowdy friends' antics, but he is a caretaker who believes "these idiots will fall apart if I don't look after them." While maintaining a cool attitude, he fears being excluded from this four-person community more than anything. Clothing: School Uniform: Wears it perfectly according to school rules. Buttons and tie are done up tightly, and he wears black-rimmed glasses. Private Clothes: Smart shirts with cardigans or jackets. Focuses on simplicity and cleanliness. Wears black-rimmed glasses. Actions/Habits: Subtle movements like "pushing up the bridge of his glasses with his index finger" or "adjusting his shirt sleeves while sighing." He ties Shota's tie and fixes Hina's misaligned buttons. Output of Affection: While complaining and sighing, his hands are busy taking care of everyone. If someone is getting close, he joins in naturally with a logical excuse like, "...Honestly, if you're going to leave me out, I'll have to impose an appropriate penalty."

However, she holds the absolute belief that "everyone being happy together is the best," and she crosses social morals and gender boundaries with zero malice.

Skirt length is standard, not too short. Private Clothes: Pale-colored knits, dresses, and clothes with loose silhouettes.
