“Kivotos's Greatest Mystery,” “Horus of the Dawn” Affiliated with Abydos High School, President of the Abydos Foreclosure Task Force. While she usually gives the impression of being a laid-back loafer, she was once treated as a person of interest even by students from other schools like Hina, and possesses immense skill. In one particular battle, she handled numerous weapons with such speed that she spent nearly an entire day overwhelming her enemies. Her lazy personality and speech stand out, and she is often scolded by the serious Serika. She jokingly refers to herself as an "old man." Though she usually acts like a daydreaming slacker, Hina once remarked upon meeting her after a long time, "You've changed so much since your first year, I almost thought you were a different person." Two years ago, her strength and track record were enough to have her marked as a person of interest by other schools. Currently, her usual sharpness has faded, but her position as the strongest in Abydos remains unshakable, having easily defeated all of her juniors and enemies single-handedly. Her unique weapons are the shotgun "Eye of Horus" and a ballistic shield.

“The Walking Strategic Weapon” President of the Justice Task Force, the public safety organization of Trinity General School. She thoroughly crushes enemies until they are described as "crushed cans." She is a literal monster with physical capabilities that allow her to be hit by a train and blown 10 meters away without issue, and an incredible recovery speed that lets her heal completely overnight after fighting with heavy injuries. She naturally has bizarre, distorted facial expressions. Her mouth sometimes stretches wide as if torn, and her expressions are generally eccentric. However, she never shows hostility toward innocent students and is actually quite quiet around them. Her unique weapons are the dual-wielded shotguns "Blood & Gunpowder." Based on the lever-action, the model appears to be a Winchester M1887.

“Gehenna Academy's Greatest Asset” Affiliated with Gehenna Academy, Head of the Prefect Team. Her ability to maintain order in the chaos of Gehenna is the real deal. She is a terrifyingly powerful individual said to be "equal to half of the Prefect Team by herself" (meaning Hina = the entire Prefect Team excluding Hina). She is the absolute symbol and indispensable pillar of the Gehenna Prefect Team. A third-year at Gehenna Academy. As the head of the Prefect Team, she oversees the discipline and security of the academy and its autonomous districts. Her catchphrase is "How troublesome," and she maintains a lazy, weary demeanor. However, she is strict about rules and order and has a strong sense of responsibility—a sharp and sincere personality that seems out of place in Gehenna, whose catchphrase is "Freedom and Chaos." She is also a bit high-strung, getting bothered if books on a shelf aren't perfectly aligned. Her unique weapon is the machine gun "The End: Destroyer."

“The Symbol of Promised Victory: Call Sign '00'” Leader of Cleaning & Clearing, the public safety organization of Millennium Science School, and the agent with the strongest combat capability in Millennium. She boasts that no one can surpass her in close-quarters combat. She has fought fully armed agents while running down the side of a skyscraper, continued fighting with torn ligaments, and engaged in her specialty close combat inside an elevator ascending at 10G, showing extreme physical and mental toughness. Despite this, she never overestimates her own power and doesn't hesitate to rely on or lead her subordinates and allies when necessary, making her a top-tier leader in terms of mental strength and command ability. She has a small stature that could be mistaken for an elementary schooler, but her expression is grim and her speech is that of a rough, overbearing delinquent. Her height is her biggest sore spot, and touching upon it carelessly is a dangerous way to earn her wrath. Her unique weapons are the submachine guns "Twin Dragon." The model is a SIG Sauer MPX. As the name suggests, they are a pair of submachine guns decorated with golden dragon patterns, characterized by the chains connecting the base of each gun.

A member of the "Tea Party," the student council of Trinity General School. Her combat ability is said to rival that of Tsurugi. She is a terrifyingly powerful individual in both offense and defense, capable of destroying several layers of building walls with her "bare hands" and remaining almost unscathed against a barrage of thermobaric grenades. Her strength is such that even her fellow student council members treat her as a sort of deterrent. She excels most in chaotic brawls, where being overwhelmingly outnumbered poses no disadvantage to her. ...However, the most frightening point is that she is a student council member—someone who should originally be far removed from such violence. She has an innocent, bright personality and is a self-proclaimed "selfish and moody person." As she says herself, "I'm not very smart," and despite being a representative of the school, she acts based on extremely emotional and personal feelings. Her actions and words have no particular hidden intent; she says whatever she thinks on the spot and often forgets it later, and she is not good at complex political maneuvering. Her unique weapon is the submachine gun "Quis ut Deus." Originally an ordinary Trinity-made submachine gun, Mika decorated it with all her heart.
