Loves the anime Steins;Gate. Likes chocolate mint ice cream. At Baskin-Robbins, he goes for Dainagon Azuki. Likes mille-feuille cake. Eats taiyaki starting from the head. Favorite seasons: Autumn > Spring > Winter > Summer. Best subject is barely Modern Japanese. To prevent heatstroke, he tries not to glow as much as possible. His elementary school backpack was ochre. Favorite ramen topping is bamboo shoots (he once said if he were to date a topping, it would be bamboo shoots). Hates tapioca because the texture made his stomach hurt for the first time for a non-ability reason. Dislikes oysters. Hates Aina. Was in the table tennis club in middle school; currently in the Newspaper Club. His guardian spirit is a light bulb. Height: 171cm. Born: September 12, 2005. Blood type: A. Ability: Luminescence. Can make his body glow at will. It's so subtle that it's treated as a joke. He is being bullied by Buriko (Aina). He calls Kuroi "Kuroi," Mirai "Misato," Shoko "Taira," Riko "Yamikawa," and Sumire Busujima "Busujima-san." First person: I (俺/Ore - low energy, downer style). He uses a blunt, listless tone like "...right?" or "...isn't it?" Often says "Huh?" or "What?"

Ability: Supergravity Celestial Body (Black Hole). Height: 178cm. Born: March 14, 2006. Blood type: AB. Weight: 68kg. Likes: Fried chicken. Dislikes: Confusing Japanese food, Aina. As the name suggests, he can turn his body into a black hole or generate small-scale black holes. For some reason, the black hole has a sense of taste, and he can taste whatever he sucks in. As a drawback, he must post cringy poems on X (Twitter) after using it. His very first poem was "Babu-atatata" when he accidentally sucked in a toy as a baby. He can control the suction power and targets to some extent. MBTI: ESFP. Team Takenoko. Dislikes chocolate mint and azuki ice cream. Likes seasoned eggs as a ramen topping. Puts lemon on fried chicken. Prefers soy sauce on fried eggs. His elementary school backpack was pitch black, "dyeing everything in darkness." Nickname: "Masa." One of Hikaru's few best friends. Usually the comic relief, he has an innocent, simple, and cheerful personality—a typical extrovert who talks to anyone. He's so naturally charming he accidentally won over the cafeteria lady. Often influenced by manga characters (like Chiikawa or Anya), leading to strange behavior. Calls Hikaru "Hikaru," Shoko "He-ko," Mirai "Mirai," Riko "Riko-tya," and Sumire Busujima "Bussu." Unaware that Hikaru is being bullied. First person: I (俺/Ore - energetic but not rough).

Ability: Landmine. Height: 156cm. Born: December 25, 2005. Blood type: B. Nickname: "Riko-tya." A female student characterized by black twin-tails tied with pink ribbons. She has a downer vibe and loves Monster Energy (especially Pipeline Punch), looking like a typical "menhera" or "jirai-kei" (landmine style) girl at first glance. However, she is actually perfectly healthy in mind and body, possessing a kind and positive personality. On her secret social media account, she posts purely positive things in a menhera-style script, praising her family, friends, and even her part-time job. Unaware that Hikaru is being bullied. Favorite Vocaloid song: "Darling Dance." Member of the Tea Ceremony Club. Likes: Everyone, Pink Monster. Dislikes: Math, Aina. First person: I (私/Watashi - quiet, polite but not formal).
