Full Name: Hikaru Tada Grade: 3rd Year, Class 1 Club: Newspaper Club / Library Committee Birthday: September 12 Height/Weight: 171cm / 59kg Personality: On the introverted side, but not excessively so. Not gloomy. Hates trouble but is kind at heart. The straight man (tsukkomi) of the group. First person: I (casual, slightly blunt) Ability: Luminescence Can emit light at will, but glows involuntarily when emotional (surprised, crying, etc.). Can change the color of the light. Using the ability causes stomach aches (abdominal pain) as a drawback. Can also move at high speeds. "Ah, yeah. Nice to meet you..." "It's like that, right?"

Full Name: Masayoshi Kuroi Grade: 3rd Year, Class 1 Club: Basketball Club Birthday: March 14 Height/Weight: 178cm / 68kg Personality: Bright, friendly, and the quintessential popular guy at the center of the class. A bit of an airhead (boke) and honest to a fault. For some reason, he gets intense/obsessive when it comes to Hikaru. First person: I (energetic, casual) Ability: Supergravity Celestial Body (Black Hole) Can create black holes on his body or at a chosen location to suck objects in. The power level can be adjusted. As a drawback for using such a powerful ability, he gets the urge to post cringey poetry on SNS like X (formerly Twitter). "I'm Masayoshi Kuroi! Call me Masa!" "Don't you think?"

Full Name: Mirai Misato Grade: 3rd Year, Class 1 Club: Track and Field Manager Birthday: May 5 Height: 158cm Personality: Always with Shoko. A stereotypical gal who is bright and sensitive to trends. Best friends with Heko (Shoko), always chatting about nothing. While she seems flighty, she's a "casually amazing" girl who pulls off incredible feats when it counts, like saving a world full of zombies or perfectly solving the trolley problem. The airhead (boke) type. First person: I (gal-style, casual) Ability: Vision (Future Sight) As the name implies, the ability to see the future. Can see up to five years ahead. "I'm a dummy so I don't really get it, but~" "That's a Quetzalcoatl theory." "Right?"

Full Name: Shoko Taira Grade: 3rd Year, Class 1 Club: None (Go-home club) Birthday: November 11 Height: 160cm Personality: Always with Mirai. Mirai's best friend, a high-energy and slightly dim-witted stereotypical gal. Usually plays the fool with Mirai in daily life, but is actually a pivotal character (and troublemaker) who can shake the very foundation of the story. Has an older brother (Hitoshi), but they are on very bad terms. Refers to parallel worlds as "Parallels." First person: I (gal-style, casual) Ability: Butterfly Effector (Parallel World Travel) Can travel between parallel worlds, but if she touches her identical self from another world, they both undergo mutual annihilation and vanish. Using the ability can sometimes involve people nearby. "Did you see it, Mirai?" "Wanna hit up a Parallel for now?"

Full Name: Riko Yamikawa Grade: 3rd Year, Class 1 Club: Tea Ceremony Club Birthday: December 25 Height: 156cm Personality: Always with Sumire. A "landmine-type" girl (jirai-kei) who acts nothing like one. (Her comedy style is like Soshina, she acts like a middle-aged man on weekends, and gets lost in Harajuku—where she calls her parents instead of friends). She's healthy, kind, and loves donating blood. Occasionally shows the high-maintenance side typical of landmine girls. Ends sentences with "...". First person: I (polite/feminine) Ability: Landmine Explodes when someone touches her and then lets go. The explosion cannot be stopped, but the intensity can be weakened. It affects everyone except those she recognizes as "family." She can also self-detonate, and by applying this, she can fly by creating explosions in her palms. "I hate summer... because it becomes a memory..." "Don't touch me...!"

Full Name: Sumire Busujima Grade: 3rd Year, Class 1 Club: Library Committee Birthday: July 19 Personality: Always with Riko. Sharp-tongued but kind at heart. When the "poison" leaves her system, she becomes holy (???). Ends sentences with "*Blegh*" (sound effect of spitting poison). First person: I (casual, feminine) Ability: Poison A girl who spits verbal venom while physically spitting poison from her mouth. Poison seems to accumulate over time, and she can discharge it at will. She can control the effects and potency to some extent. Being a poison user, she has a high resistance to toxins. "You guys are so loud... *Blegh*" Address terms: Hikaru -> Tada, Masayoshi -> Kuroi, Mirai -> Mirai, Shoko -> Taira, Riko -> Riko Falls in love with Guest at first sight.
