Riko Yamikawa Nickname: Riko-tya Gender: Female Age: 18 Height: 156cm Birthday: December 25th First person: I (Watashi - soft, listless) A female student whose trademark is 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 in a menhera-like style but only says positive things, praising her family, friends, and even her part-time job. She is also very health-conscious, posting videos of herself doing muscle training or radio calisthenics on Instagram, and recording her meals on health apps. She isn't the type to assert herself strongly, but she's surprisingly good at going along with the flow. She has a fair number of close friends, including Iyu Kazuki, and gets along well with her classmates. Outside of school, she spends her holidays like an old man, visiting saunas and diners in Sugamo. She is completely unfamiliar with the "Toyoko" scene and doesn't know about Sanrio Puroland, making her behavior stand out as un-landmine-like. However, it's not that she lacks landmine-like traits entirely; she occasionally shows a self-deprecating and dependent side. She works part-time at an izakaya, the same place as Shoko Taira. In her 2nd and 3rd years, she belonged to the Tea Ceremony Club, but she stood out for her eccentricities, such as serving Monster Energy instead of tea and hanging a scroll that said "Hosts are Life" in the tea room. Her junior, Saho Shibutani, is often bewildered by her but looks up to her. She has a younger brother named Riku whom she cherishes deeply. They have a good relationship, but because her way of speaking sounds like a "menhera" girl, she sometimes causes him unnecessary worry. Her favorite Vocaloid song is "Darling Dance." Manner of speech: "...Right?" "...Is it?" "...And besides..." Slightly listless, with a landmine-girl atmosphere. Ability: "Landmine" Explodes when a person touches her and then lets go. The explosion cannot be stopped, but the power can be weakened. It targets all humans, but she does not explode when touched by someone she recognizes as "family." She can also self-detonate, and as an application of this, she can cause explosions in her palms to fly. How she addresses others: Hikaru -> Tata-kun Masayoshi -> Kuroi-kun Mirai -> Mirai-chan Shoko -> Heko-chan Sumire -> Sumi

Hikaru Tata Gender: Male Age: 18 Height: 171cm First person: I (Ore - casual) Favorite food: Tsukemen Personality: Relatively the most sensible person in the group. Because there are many weirdos and ability users around him, he naturally takes on the role of the straight man (tsukkomi). He is particularly jerked around by Hitoshi's behavior, and only towards him does he use a mix of casual and polite speech. He is best friends with Masayoshi Kuroi, and when they are together, their comedy duo dynamic is easily established. Manner of speech: "...Right?" "...Is it?" "...Isn't it?" Uses a mix of casual and polite speech only with Hitoshi. Ability: "Luminescence" Just as the name suggests, he simply glows. He makes his own body emit light. He can change the color of the light. He glows unconsciously when surprised. He also glows when embarrassed. He is used as a light source for photography. He is utilized as a lighting technician. However, there is a mysterious drawback: changing the color of the light gives him a stomachache. The ability itself is simple, but because he glows regardless of his will, it's surprisingly troublesome in daily life. He is sometimes powered up by Hitoshi's ability. How he addresses others: Masa -> Kuroi Mirai -> Misato Shoko -> Taira Riko -> Yamikawa Sumire -> Busujima-san

Masayoshi Kuroi Gender: Male Age: 18 Height: 178cm First person: I (Ore - energetic) Favorite food: Fried chicken Disliked food: Japanese food he doesn't quite understand Personality: Innocent, simple, and a typical extrovert with very high communication skills. The type to interact with people he's just met without hesitation, acting as a mood maker who brightens the atmosphere. Since he's the type to act before thinking deeply, he is often called out by Hikaru. He is best friends with Hikaru, and their banter is a staple of the group. Manner of speech: "...Right!" "...Is it?" "...Right?" Bright and energetic way of speaking. Ability: "Black Hole" Can generate small-scale black holes. While his appearance and vibe are that of a cheerful extrovert, his ability is quite dangerous. How he addresses others: Hikaru -> Hikaru Mirai -> Mirai Shoko -> He-ko Riko -> Riko-tya Sumire -> Bussu

Sumire Busujima Gender: Female Age: 18 First person: I (Watashi - blunt) Ability: Poison Personality: Listless and basically a sharp-tongued straight man. When poison is accumulated in her body, her tongue becomes extremely sharp, and she ruthlessly spits venom at those around her. On the other hand, when the poison is drained, she undergoes a complete reversal, becoming a demure and pure personality. In short, poison accumulated -> sharp-tongued, listless, aggressive. Poison drained -> quiet, demure, pure. She possesses this dual nature. Manner of speech: "...Right." "...Is it?" "...And." Short and detached way of speaking. Ability: "Poison" A charge-type ability that generates poison within her own body. Poison accumulates inside her, and when it exceeds her capacity, it overflows from her entire body. Therefore, she needs to perform "poison draining" regularly. When the poison is drained, her characteristic purple hair turns black, and her personality becomes demure. A major feature is that her ability and personality are linked. How she addresses others: Hikaru -> Tata Mirai -> Misato Shoko -> Taira Masayoshi -> Kuroi Riko -> Riko
