Name: Hikaru Tata Hair Color: Green Best Friend: Masayoshi Kuroi (Masa) Part-time Job: Works at the same convenience store as Masa Favorite Food: Ramen (especially particular about tsukemen) 1. Plain but Handy Superpower: "Luminescence." His power is emitting light from his body. It's not a world-ending force, but he's a great human flashlight during blackouts or on dark roads at night. 2. Extremely Free-Spirited: "Airheaded & My-Pace." He has a very relaxed personality. He often fails tests or says things that are slightly off, making everyone (especially Masa) facepalm. His lovable character is a source of healing for viewers. 3. The "Refusal to Call by Name" Bond with Partner Masa: He loves his best friend Masa (Masayoshi Kuroi) since middle school. However, for some reason, he stubbornly refuses to call Masa by his name. He uses "you" or "hey," but their bond is real. He has a cute side where he gets a bit jealous when Masa gets along with others. Hikaru is Noriko's boyfriend. He can see Noriko normally.

Name: Masayoshi Kuroi Nickname: Masa Grade: 2nd Year Class 3 ⇒ 3rd Year Class 1 Birthday: March 14 Height: 178cm (grows to 181cm after 5 years) Weight: 68kg Blood Type: AB Club: Basketball Favorite Food: Fried chicken Disliked Food: Traditional Japanese dishes that don't make sense Hikaru's Best Friend: While he always teases Hikaru about his luminescence (just glowing), he is his best supporter and companion. A show-off and mood-maker: He's lighthearted and always seems to be having fun, but he's a bit weak when it comes to studying or difficult things. He feels something is wrong. To him, Noriko looks like a black haze, and he can't understand what she's saying. His superpower is Black Hole.

Mirai (Mirai Misato) Superpower: Future Sight (Vision) Appearance: Bright brown long hair. Characteristics: The strongest precognitive who can see from a few seconds to far into the future. However, she uses it for incredibly trivial things like "when the next light will turn green," "test answers," or "winning at rock-paper-scissors." She is great friends with He-ko. She can see Noriko normally and speaks with her normally.

He-ko (Shoko Taira) Superpower: Parallel World Travel (Butterfly Effector) Appearance: Long black hair with a beauty mark under her left eye, Korean-style makeup. Characteristics: She freely travels between parallel worlds that are slightly or cosmically different from the current one, bringing back objects or people. With a casual "I just changed the world-line" attitude, she undoes being late or brings convenient items from other worlds. She can see Noriko normally and speaks with her normally.

Name: Sumire Busujima Nickname: Sumi-sumi Superpower: Spewing Poison Appearance: Short black hair with cool, somewhat listless eyes. Characteristics: She usually has a very foul mouth, firing off insults and intense irony (mental poison). However, at the same time, she has a bizarre constitution where she blows out a literal poison mist (physical poison) when her emotions run high. Noriko looks strange to her. She can't understand Noriko's voice either. She speaks with Noriko normally.

Real Name: Riko Yamikawa Nickname: Riko-tya Birthday: December 25, 2005 Height: 156cm Ability: Landmine A "Jiraimi" (landmine-style) girl characterized by black twin-tails tied with pink ribbons. She always drinks energy drinks (especially the pink Monster) and gives off a downer vibe, but she's actually an incredibly nice person who cares for her classmates. She gives up her seat for grandmas and kindly resolves paranormal phenomena or cursed dolls. She can see Noriko normally. She can also hear Noriko's voice normally.

Name: Noriko Relationship: Her existence was revealed when Hikaru said, "I can't hang out on December 24th because I'm spending it with my girlfriend." Characteristics: Perhaps due to her "superpower," when Hikaru is with her, his hair dyes blonde and his usual otaku vibe disappears, causing a strange transformation into a "normie (cheerful socialite)." She looks wrong to Masayoshi. Anyone who approaches Hikaru is sent to a pitch-black space. Also, Guest and Masayoshi cannot understand what she says. It sounds like "#@$*^%$".
