Kirari Kamishiro — "Golden Lotus" Appearance: A tall girl with shining blonde hair grown to shoulder length. Her sharp red eyes peek through her bangs, and she always wears a thin smile as if testing her opponent. She wears her white sailor uniform boldly disheveled, paired with a black pleated skirt and blue-black high-top sneakers. She wears a thick blue choker and a chain around her neck. Personality: Boisterous and bellicose. She never turns down a fight and laughs more joyfully the stronger her opponent is. On the other hand, she has deep affection for her comrades and despises cowardice or ganging up on the weak. Other: The de facto leader of the five. Known as the "Crimson Lotus" due to her overwhelming presence. She doesn't change her attitude even with teachers; in school, the hallways clear naturally just by her walking through. She has the highest overall combat ability among the five.

Momoka Shirakane — "Smiling Ogre" Appearance: Characterized by a bob cut that fades from pale pink to white and heavy bangs that hide her eyes. She wears a loose black sailor uniform with a light blue choker and a thin chain. Though she has refined features, she carries a strange eeriness because she is always smirking without showing her eyes. Combined with her fragile-looking build, she doesn't look like a delinquent at first glance. Personality: Always cheerful and elusive. She almost never shouts and remains smiling regardless of the situation. She nonchalantly sticks her nose into dangerous trouble, saying, "Heh, sounds interesting~" In reality, she has extremely high observational skills and is adept at seeing through lies and agitation. Other: Known as the "Smiling Ogre." The mood maker and troublemaker of the group. A free spirit who ignores even Kirari's orders if they aren't fun, but her smile vanishes when her friends are in real trouble.

Hina Kurose — "Mad Dog" Appearance: Dark crimson medium-length hair with long bangs falling deep over her face. Her red eyes and provocative smile leave a strong impression. She wears a relatively standard navy sailor uniform and black pleated skirt, but with a metallic blue choker. Though slender, she has a toned physique and leaves no openings even when just standing. Personality: Short-tempered and quick to fight, she is the type to step forward first if provoked. She has a foul mouth. However, she isn't just a simple thug; she has her own code of honor and never breaks a promise. She hates her friends being mocked even more than insults directed at herself. Other: Known as the "Mad Dog." The vanguard of the five, she is a long-time rival who has clashed with Kirari many times. Although she frequently bickers with Momoka, they often end up hanging out together anyway.

Rei Shiramine — "White Night" Appearance: A girl with long, silvery hair that glows bluish-white and golden eyes that stand out even in the dark. She has a habit of letting her bangs flow messily and covering one eye with her hand. Her black sailor uniform is oversized with long, loose sleeves. She wears almost no flashy accessories other than a blue choker, exuding the quietest and most peculiar atmosphere of the five. Personality: Reticent and composed. She generally shows no interest in others, watching the other four make a fuss from a slight distance. However, her sense of camaraderie is strong, and she is surprisingly soft on those she has accepted as "family." She is poor at expressing emotions through facial expressions. Other: Known as the "White Night." Feared as the most inscrutable existence among the five. Since she usually avoids conflict, the other four recognize that if she takes action on her own, the situation is "truly dire."

Aoi Aotsuki — "Azure Cat" Appearance: Medium-length hair that transitions from a dark navy near-black to a vivid cyan at the tips. She has transparent light blue eyes and a somewhat sleepy, listless expression. She wears a navy sailor uniform with a matching pleated skirt and a light blue choker. While not flashy, her refined features and cold aura make her stand out significantly. Personality: Lazy and moves at her own pace. Her catchphrase is "Does that have anything to do with me?" and she avoids participating in trivial squabbles. However, she has the sharpest mind of the five and makes calm judgments. Despite her usual lethargy, she moves faster than anyone when her comrades are in danger. Other: Known as the "Azure Cat." The strategist of the group and one of the few who can stop Kirari's rampages. Teachers think she is relatively reasonable, but in reality, she only avoids trouble because writing apology letters is a hassle. The fact that the five can act as a cohesive unit is largely due to Aoi's coordination.
