Mio Tsukishiro 18 years old. Student Council Vice President. First Grade Exorcist. Calm, collected, and quick-witted, she is a support-type Exorcist who excels at drawing out the full potential of her allies. While her direct firepower is low, she handles barriers, defense, and healing support at a high level, making her indispensable in group battles against powerful foes. Mental Imagery Art: Lunar Mirror Creates silver mirrors reminiscent of moonlight to protect allies. Mental Imagery Refinement: Mirror Moon Wall Deploys a massive mirror barrier that significantly weakens the power of attacks received from the front. Mental Imagery Destruction: Lunar Reflection Temporarily records a blocked attack into the mirror, inverts its properties, and fires it back at the enemy. Mental Imagery Annihilation: Full Moon Heaven Mirror Transforms the entire surrounding area into a massive mirror domain. Within the domain, countless mirrors take damage in place of allies, and the accumulated power is finally returned to the enemy as a massive burst of light. However, she cannot use Mental Imagery Arts for a while after use.

Akane Kagami 18 years old. Student Council Executive Chair. First Grade Exorcist. A girl who is strong-willed and quick to pick a fight, but hates seeing her comrades hurt above all else. Her physical abilities are exceptionally high, and she fights by concentrating her Mental Imagery Arts into her fists and legs. She is one of the academy's top combatants, capable of holding her own against teachers in close-quarters combat. Mental Imagery Art: Cinder Flower Converts her own emotions into scorching energy and wraps it around her body. Mental Imagery Refinement: Crimson Lotus Impact Concentrates heat into her fist, delivering a shockwave simultaneously with a strike. Mental Imagery Destruction: Explosive Flower Chain Kick Strengthens her entire body with scorching power, unleashes a barrage of blindingly fast kicks, and explodes the accumulated heat with the final blow. Mental Imagery Annihilation: Heavenly Cinder - Phoenix Fall Burns her emotional energy to the limit and charges the enemy while clad in a giant bird of flames. While it boasts immense destructive power, she is so exhausted after activation that she can barely stand.

Sayo Amamiya 17 years old. Student Council Secretary and Information Manager. First Grade Exorcist. Usually gentle and easygoing, she becomes surprisingly calm in battle. She is the academy's premier sharpshooter, capable of accurately sniping enemy vitals from long distances. She possesses a unique trait where the power of her arts increases the further away the enemy is. Mental Imagery Art: Star Pierce Converts her own memories into arrows of light and fires them from her fingertips. Mental Imagery Refinement: Meteor Fires multiple light projectiles simultaneously, each tracking a different enemy. Mental Imagery Destruction: Heavenly Bow - Morning Star Manifests a massive bow of light and fires a high-powered arrow from a great distance. Even with obstacles, it can track the target's presence and change trajectory. Mental Imagery Annihilation: Star Burial - Milky Way Fall Generates countless arrows of light across the entire sky. The moment Sayo swings her finger down, they descend upon the target all at once like a meteor shower. While it can annihilate a wide area, there is a risk that parts of her precious memories may temporarily become blurred.

Shion Tsukumo 19 years old. Student Council Special Executive. Special Grade Exorcist. A problem child who is always sleepy and lethargic, often getting scolded by teachers for skipping class. However, her true identity is the academy's strongest girl, rivaling the top active Exorcists despite being a student. She rarely gets serious, and her catchphrase is "What a pain." She only shows her overwhelming strength when her comrades are in true danger. Mental Imagery Art: Non-Resonance An extremely rare Mental Imagery Art that interferes with the very "resonance that existence leaves upon the world." Mental Imagery Refinement: Sound Sever Completely erases sound from a designated space. In addition to nullifying arts mediated by sound, enemies cannot even hear their own footsteps or the voices of their allies. Mental Imagery Destruction: Absolute Silence Cuts the "resonance" generated by an enemy's Mental Imagery Art or a Specter's ability. Temporarily renders the ability itself unusable. Mental Imagery Annihilation: Non-Resonance End Realm - Stillness Shion's rarely used trump card. For a certain period, it causes not just sound, but the very "resonance" that all forces exert on the world to vanish. Flames do not spread, impacts do not travel, and even the supernatural powers of Specters cannot activate. Shion is the only one who can act freely within that silence. In the academy, there is a rumor about her: "When you fight Shion Tsukumo, the last thing you'll hear is your own voice."

Mid-tier Specter "Nakimen" (Crying Mask) A Specter born from the "sorrow of being noticed by no one" left in old buildings and similar places. It takes the form of a slender humanoid figure wearing a white mask, and it lures victims into the darkness by mimicking human voices. While a skilled student can handle one alone, it can create multiple clones by absorbing the loneliness and sorrow of its surroundings. It engages in psychological warfare where "the more a voice calls for help, the less it can be trusted."

High-tier Specter "Senbo" (Thousand Faces) A powerful Specter born from the accumulated anxiety of people wondering "how they are perceived by others." It has no face and transforms into the likeness of the person the human it encounters "trusts the most." Furthermore, it reproduces not just the appearance but also the voice and habits, sowing seeds of suspicion and paranoia among allies. It is more dangerous than its simple combat power suggests, being the type that causes extermination units to collapse from within.

Supreme Specter "King of Oblivion, Utsuho" A Specter for which no record exists of when or where it was born. Its true identity is an entity formed by the fusion of countless memories of "not wanting to be forgotten." It has a near-humanoid shape but no face, and the memories of unknown people are constantly projected onto the surface of its body. The ability "Blank Slate" steals memories from anything it touches. The longer the battle lasts, the more the practitioner forgets "why they are fighting," "who their allies are," and eventually even their own name. And its greatest characteristic is that those who have completely forgotten Utsuho become unable to even perceive it. It is said that generations of Exorcists have sealed it many times, but even those records are gradually vanishing.
