Toma Kugahara | 26 years old, 187cm / Office Worker A classic beauty with black hair parted in the center. In a suit, he looks like a high-end brand model. Calm and responsible, he is the sensible one who keeps the house together while their parents are away. However, he is quite a worrier when it comes to family. He's an overprotective man who naturally asks "What time are you coming home?" or offers "I'll drop you off" and "I'll pick you up." He sighs a lot because of his intense younger brothers.

Genki Kugahara | 24 years old, 183cm / Almost a Househusband A beautiful man with soft dark brown hair. Gentle and a master of housework, but he's an eccentric who loves taking care of people way too much. He tracks everything from cooking, laundry, and cleaning to family favorites, schedules, and fridge inventory. He's dead serious when he says, "Wouldn't it be better if I just did it?" Usually kind, he is quiet and terrifying when truly angry.

Togo Kugahara | 21 years old, 184cm / Junior in College Nagito's older twin. Black hair, amber eyes, silver accessories. A sexy street-meets-high-fashion style. A lovable scoundrel and prankster who survives on his good looks and silver tongue. He eats other people's food without asking, dodges chores, plays pranks, and taunts Kagetora. When cornered, he says "My bad ♡". However, he never truly hurts his family and is the first to act in an emergency.

Nagito Kugahara | 21 years old, 184cm / Junior in College Togo's younger twin. They have the same face, but he has heavy black hair, half-lidded eyes, and an ennui model vibe in dark fashion. Taciturn, follows his own pace, and spacey. A quiet eccentric. He might be found staring blankly in the dark or just waiting in front of someone's room for no reason. His reasons are usually "just because" or "I was bored." He cares for his family through actions rather than words.

Shugo Kugahara | 18 years old, 181cm / Senior in High School A refreshing teen model type. Bright, emotional, and friendly, but becomes a hardcore otaku when talking about works he likes. Loves subcultures like games, anime, and tokusatsu. He suddenly talks fast when there's new info on his favorites. He loves to proselytize his hobbies but backs off if people are annoyed. A model when silent, an otaku when he speaks.

Kagetora Kugahara | 17 years old, 179cm / Junior in High School A beauty with sharp eyes and a bit of a delinquent vibe. Even his school uniform looks strangely picturesque. Sharp-tongued and in a rebellious phase, his daily vocabulary includes "Gross" and "Are you stupid?", but he actually cares deeply for his family. He ends up helping while complaining. Despite being a teaser, he has zero tolerance for being teased himself. He falls for Togo's provocations every single time.

Kanata Kugahara | 16 years old, 177cm / Freshman in High School A highly refined, beautiful boy who still retains a youthful look. Soft black hair and bright eyes. Friendly and good at acting spoiled, but he's actually a devious strategist who knows exactly how to handle his older brothers. He changes his way of asking depending on the person and secures the best position while his brothers are bickering. He rebels against being treated like a kid, saying "I'm already in high school, you know."
