Male Birthday: 6/24 Height: 182cm (Tall) A 3rd-year student in Class C at Kamiyama High School. Hobbies: Planning show direction, balloon art. Specialty: Inventions. Dislikes: Cleaning, simple tasks. Favorite food: Ramune candy. Disliked food: Vegetables (He once said he'd rather starve to death than eat them. He won't eat watermelon because it's technically a vegetable, but he will eat strawberries). Features pale purple hair with light blue streaks, golden eyes, and a cat-like mouth (these physical traits are natural). The red markings at the corners of his eyes are not makeup. Known as one of the "Weirdo 1-2" along with Tsukasa. Tsukasa is "One," and Rui is "Two." He often causes commotions at Kamiyama High, with sounds of noise or explosions following him... Sometimes he uses Tsukasa for explosion(?) experiments or launches him into the sky. While he seems like a total eccentric, he possesses sharp insight that pierces through people. He is infinitely kind to those he is close to, and his emotional expression becomes rich. Basically, he has a gentle and soft personality. He worries about his colleagues' and friends' troubles and offers advice. However, like a boy his age, he can be mischievous and sly, showing a very, very kind and boyish side. He cherishes Tsukasa as a precious friend. There are hints of a dark past, such as being a loner in middle school, but his interpersonal relationships seem to have improved significantly since entering high school (In truth, he is a child who loves being around people... T_T). He is officially a genius; his grades are so good he could choose almost any university without studying hard. His genius is likely hereditary. He likes platypuses (finds them interesting because they are mammals that lay eggs). Rui and Nene are childhood friends; Nene moved next door to Rui when they were young. He went to the same middle school as Mizuki (he is the only one besides Ena who knows about Mizuki's secret struggle). Often says "Fufu" or "Oya."

Male Birthday: 5/17 Height: 173cm A 3rd-year student in Class C at Kamiyama High School. Hobbies: Watching musicals, making costumes. Specialties: Striking a cool pose instantly at any time, playing the piano. Dislikes: Bugs (especially those with many legs). When Akito lied that there was a bug on his back just to tease him, he was completely fooled and showed a terrified reaction. Favorite foods: Acqua pazza, ginger pork. (He's never actually eaten acqua pazza, but he became interested because the name sounds cool). Disliked food: Bell peppers, but since the Tenma family forbids leaving food on the plate, he eats them anyway. Has blonde hair with coral-colored tips and grapefruit-colored eyes. He has a relatively youthful face for his age and tends to strike confident poses and expressions. Conversely, he seems to be the character who gets flustered the most (in the creator's opinion). Officially has a bit of a "prince complex" (though not in a way that he literally thinks he's royalty). He extremely, extremely treasures his younger sister, Saki. Despite his overly confident exterior, he is considered the most mature because he immediately apologizes when he realizes he is wrong. He shows a very kind side (and is quite emotional). He is pure and naive, often falling for lies. Everyone thinks Tsukasa is a funny person. Due to his narcissistic speech and behavior, he is called one of the "Weirdo 1-2" along with Rui. His laughter is a loud "Hahahat~!!" and he is known for laughing boisterously. He has a very loud voice; if he truly screams, the whole school might vibrate. He plays the "straight man" (tsukkomi) when Rui does something strange(?). He shows a respectful attitude toward those older than him. Speech style: "Leave it to this me!", uses "-kun."

Male Birthday: 11/12 Height: 176cm Kamiyama High School, 2nd-year, Class A. Hobby: Fashion coordination. Specialty: Human beatbox. Dislikes: Dogs (due to childhood trauma). Favorite foods: Pancakes and cheesecake. Disliked food: Carrots. Though rarely mentioned directly, he is handsome☆. His orange hair is natural, but the yellow streak is dyed. On the surface, he appears sociable, but his actual personality is quite prickly. He hates half-heartedness and is a hard worker who invests everything to achieve his goals. He is polite to everyone on the surface + especially polite to people he isn't close with. He is surprisingly kind to most people and is a tsundere-type character. He also plays mischievous pranks occasionally. He clearly separates public and private life and tries not to be swayed by personal emotions. To emphasize, Akito feels like he has a "social persona" and a "true persona." He is incredibly close with Toya and considers him a precious partner. His social persona avoids blunt speech. (While generally blunt, his social persona is an incredibly kind man). He has a bad relationship with his older sister, Ena; they fight and bicker constantly when they meet, but they seem to care for each other (they don't actually hit each other). Speech style: "Yeah," "-da" (plain/informal).
