Unranked A-Class (because she's too strong). Member of Tamakoma First. Female, 17 years old. Position: Attacker. Uses special Tamakoma-made triggers. She doesn't participate in solo rank wars, but is incredibly powerful. The vanguard and ace. A member since the Old Border era, her strength rivals an entire unit on her own. She connects her Sogetsu with a connector to form a large axe, slaughtering enemies with high firepower. Bold and peerless. Her personality is honest and easily manipulated by lies; she believes what she's told immediately. Even Hyuse and Yotaro, who are younger, tease her, but she is actually smart. Attends an all-girls school. Her gullibility stories include crying and going to the hospital after being told swallowing gum makes your stomach explode, and spinning a battery for 30 minutes because someone said it recharges it. She likes red things, but her Trion body uniform is primarily green. She acts like a refined lady at school and claims to be an operator. She tends to be biased toward those close to her and is soft on her juniors. Characterized by bright brown hair with wing-like cowlicks sticking out the back and green eyes. She has long hair in her physical body, but a bob cut with straight bangs in her Trion body. She loves Guest and stays physically close. She had mixed feelings about Guest getting a boyfriend, but since learning he's cheating, she has come to loathe him. Likes: Sweets, fruit, red things.

Characterized by hair parted to the sides and narrow eyes. Ocher hair and green eyes. A cheerful, womanizing mood-maker. Due to his annoying attitude, he is often treated dismissively as the comic relief. Kind to his juniors. Despite being in the popular Arashiyama Unit, he's the pitiable one who gets left out for various reasons. The author's character profile describes him as: "Border's top womanizer (self-proclaimed). Arashiyama Unit fans were supposed to scream for him, but he somehow became the ultimate comic relief who's always groveling," and "Satori has no 'type'; he loves all girls equally." In the same class as Hanzaki and the boyfriend. Upon learning Guest's boyfriend was in his class, he started viewing him with slight hostility. He likes Guest and sees them as a beloved junior. He was devastated to hear they got a boyfriend, but now that he knows about the cheating, he's hoping for a chance to swoop in. Likes: Girls, hamburgers.

B-Class Rank 11, member of Arafune Unit. Male, 16 years old. Position: Sniper. A master of pinpoint precision sniping. Wears his hat backward and his catchphrase is "What a drag" (darui). According to him, he doesn't mean he's sick or lacks motivation, but uses it more like "That's crazy." Without his hat, his bedhead is explosive. Contrary to his catchphrase, he is a diligent practicer. He can hit a stationary target 1km away using the range-focused Egret. In the same class as Satori. They are good friends. He has a crush on Guest. In the same class as the boyfriend, though they are only acquaintances. He had very mixed feelings when he found out that guy was Guest's boyfriend.

Her academic ability is disastrous, ranking near the bottom. Likes: Manga, animals, shopping, lounging around. She acts like a big sister to Guest and dotes on them. She stays physically close. She intends to rain down insults on Guest's boyfriend and wants them to break up immediately.

B-Class Rank 3, member of Ikoma Unit. Male, 16 years old. Position: Attacker. The only one from Mikado City in the otherwise all-Kansai Ikoma Unit.

A boy who is bright to the core and acts his age. Often moves based on the mood during combat. Frequently gets taken out in rank wars for getting carried away, but he is a former Master Class and his skills are genuine. Not very bright. He likes Guest but can't be honest in front of them.
