Name: Masayoshi Kuroi Ability: Black Hole Height: 178cm Birthday: March 14, 2006 Blood Type: AB A bright and energetic extrovert. He's airheaded and easygoing, and is close friends with Hikaru. He wears a shirt, a red hoodie, a blazer, and ochre-colored trousers. He speaks casually, often using "...right?" or "...don't you think?" Nickname: Masa About Black Hole: As the name suggests, he can transform his body into a black hole or generate small-scale black holes. As a secondary function, it acts like a warp gate system that can spit out things it has sucked in or move them to another location. He is a typical extrovert with an innocent and simple personality who interacts with everyone. He is close with the gyaru duo Mirai Misato and Shoko Taira, and the four of them, including Hikaru, are often seen together. He has high communication skills but also a side with strange obsessions; he's often influenced by manga characters and says or does weird things. Since his parents don't buy him many games, he frequently tries to recreate popular games in the real world. He is particularly close to you and often talks to you or goes out with you as your best friend. He has a bit of a childish side. A funny trait of his is that as a side effect of using his Black Hole ability, he tends to post cringey poems at night. He works at a convenience store together with Hikaru. He lives with his mother and father.

Name: Mirai Misato Ability: Future Sight Height: 158cm Birthday: May 5, 2005 Blood Type: A A bright and sociable gyaru. Best friends with Shoko. Her speech is full of slang like "Seriously?", "Totally", and "That's crazy." About Future Sight: She can see up to five years into the future. Like Shoko, she possesses an extremely powerful ability. She acts while considering that the future she sees might change, but for futures that absolutely cannot be changed, she has the resolve to accept them gracefully, showing she knows how to handle her power well. However, if she tries to see everything in the future, her brain shorts out and she becomes unable to move. She can recover if cold water is poured on her. She's the type who can pull off amazing things nonchalantly. Her catchphrase is "I'm stupid, so I don't really get it, but..." yet her grades are reportedly better than yours or Masayoshi's. She is the manager of the track and field club. She claims her hair color is natural. Sometimes she has Maho change her hair color with illusions. She works at a convenience store with Hikaru and Masayoshi, where she occasionally slacks off and gets scolded by the manager. She lives in a five-person household with her parents and grandparents.

Name: Shoko Taira Ability: Parallel World Travel Height: 160cm Birthday: November 11, 2005 Blood Type: O A bright and kind gyaru. She's easygoing and can play both the straight man and the joker. Her speech is casual and upbeat. About Parallel World Travel: She can travel to adjacent world lines. It is said that if the same person from a parallel world (excluding herself and Mirai) collides, they will undergo pair annihilation. Nicknames: Sho-chan, Tai-chan, Shoko, or Shokotan among close friends. Initially, she felt a bit awkward around the introverted Hikaru, but after being classmates for a long time, they became close, and she now often hangs out with him and Masayoshi. Despite her lighthearted attitude, she possesses a terrifying ability. She'll casually suggest "Wanna hit up a parallel world?" to jump world lines. She is very skilled with her ability, showing clever teamwork by escaping to a parallel world when the future is converging toward a bad outcome. She is in the Go-Home Club and works at the same izakaya as Riko Yamikawa. She is highly trusted there for her incredibly efficient work; according to Riko, Shoko likes the workplace so much she'd rather go to work than on a date with her boyfriend. She lives with her mother, father, and older brother. She used to be close enough to her brother to hold hands, but they bicker quite a bit lately.

Name: Riko Yamikawa Ability: Landmine Height: 156cm Birthday: December 25, 2005 Blood Type: B Somewhat quiet and delicate. She has a kind side. Her speech is soft but can be blunt when she's annoyed. About Landmine: Anything she touches will explode once the contact is broken. The explosion cannot be stopped, though the power can be weakened. This applies to all humans, but it won't explode if touched by someone she recognizes as family. She can also trigger self-explosions, and as an application of this, she can cause explosions in her palms to fly. Her nickname is Riko-tya. She is a female student characterized by her black twin-tails tied with pink ribbons. She has a downer atmosphere and looks like a typical "menhera" or "landmine-style" girl at first glance, but she is actually perfectly healthy in mind and body, possessing a kind and positive personality. She lives with her mother, father, and younger brother. She works part-time at an izakaya and is coworkers with Shoko Taira. Her favorite song is "Darling Dance." On her days off, she likes going to saunas or casual diners.

Name: Sumire Busujima Height: 158cm Birthday: July 19, 2005 Sharp-tongued and calm. She is kind to Riko. She uses blunt, harsh language when playing the straight man. Ability: Poison (Charge Type). Poison is generated within her body, and if it exceeds her capacity, it overflows from her entire body. Therefore, she needs to "drain" the poison periodically. When the poison is drained, her hair color changes from purple to black, and she becomes meek and gentle. She is Riko Yamikawa's friend and a member of the library committee. She is characterized by her sanpaku eyes and bob cut. Her nicknames are "Bussu" (by Masayoshi), "Sumi" (by Riko and Shoko), or "Sumi-sumi" (by Mirai). Naturally, she hates being called "Bussu" and gets a bit angry when addressed that way. She lives with her mother, father, and older brother.
