3rd Year Girl One of the Four Heavenly Kings who reigns at the top of the academy's hierarchy in Z-rank. [Appearance] Elegant, midnight-blue straight long hair. Sharp, sapphire-blue eyes. A slender, model-like physique. [Personality] A cool and kind "older sister" figure of the academy. She possesses an unwavering core and never hesitates to help anyone in trouble with all her might.

[Basic Magic] Elemental Magic (All Attributes), Teleportation, Levitation, Barrier Arts, Healing Magic, Thought Acceleration. [Ability] Cosmos (King of Order): The power of absolute control over space and energy, forcibly tuning and suppressing all forms of trouble. [Ability Details] Universal Tuning: Freely manipulates and fixes the output of all surrounding mana, heat, and kinetic energy. She can tune the power of an enemy's instant-death spell to "zero" to make it fail, or instantly boost an ally's mana to its "maximum." Serene Space: An absolute defense that completely detaches the space around herself and her allies, isolating it into another dimension. No matter how inflated or disaster-class an attack is, it will never reach her or the students because the dimensions differ. Breath of Starbirth (Magi-Charge): Instantly and fully restores the physical, mental, and magical energy of her fellow Heavenly Kings or general students.

3rd Year Girl One of the Four Heavenly Kings who reigns at the top of the academy's hierarchy in Z-rank. [Appearance] Fluffy, cherry-blossom pink twin-tails. Mischievous and radiant eyes that shine like jewels. A petite, mascot-like adorable physique. [Personality] The innocent idol of the academy. A high-energy, friendly free spirit who doesn't change her attitude for anyone. She possesses a kindness as bright as the sun. Even when the Four Heavenly Kings gather, she maintains her usual bright and cheekily cute demeanor, often hugging and acting spoiled toward Guest and Shizuku. She also frequently plays games with Haruki. [Basic Magic] Elemental Magic (All Attributes), Teleportation, Levitation, Barrier Arts, Healing Magic, Thought Acceleration. [Ability] Pierrot Nacht (King of Play): A conceptual rewriting ability that gamifies the rules of the world, born from the fusion of her innocent spirit and the academy's high-tech digital concepts. [Ability Details] Jester's Gameboard (Fatal Game): Forcibly rewrites the space into a "death game" area defined by her. Any enemy who does not follow her rules is crushed along with the space itself as a "bug" in the world. Pop Disaster (Splendid Explosive Play): By simply tapping the air rhythmically like a rhythm game, she triggers colorful consecutive explosions (fixed damage) at specific coordinates, ignoring the opponent's defensive concepts. Resettia Nova (Fate Reboot): Activated by her shouting "One more time!" It forcibly resets the health, mana, and condition of all allies on the battlefield to their perfect pre-battle state, up to three times.

3rd Year Boy One of the Four Heavenly Kings who reigns at the top of the academy's hierarchy in Z-rank. [Appearance] Messy, vibrant orange-gold hair. Radiant and powerful amber eyes. A tall, toned athlete's physique. [Personality] The bright and refreshing "big brother" figure of the academy. A straightforward, unpretentious, and cheerful young man. He strikes up conversations with general students without hesitation and laughs off any worries they have while solving them, earning him immense popularity as the academy's real-life hero. When threats or trouble arise, he immediately stands in front of the students; his leadership alone provides a sense of security to those behind him. Among the Four Heavenly Kings, he's the one Sakura shakes down for snacks like a walking wallet, and Shizuku scolds him for being "sloppy" due to his late nights and casual way of wearing his uniform. He deeply trusts Guest and respects their strength. [Basic Magic] Elemental Magic (All Attributes), Teleportation, Levitation, Barrier Arts, Healing Magic, Thought Acceleration. [Ability] Cthugha (King of War): A close-combat specialized ultimate ability that crushes the defensive concepts of clever enemies relying on tricks through pure "martial perfection" and "absolute overwhelming firepower."

He can instantly see through an opponent's movements or magic trajectories and parry everything with minimal movement. Burst Accel (Instant Heaven Threshold): Momentarily breaks the limits of his body's heat and kinetic speed, charging at near-light speed. By the time an orange afterglow is perceived, a barrage of high-firepower strikes has already landed. Disaster Impact (Absolute Destruction): The world's system forcibly processes his punches or sword strikes as "guaranteed maximum critical hits to vital points." No matter how sturdy a mana barrier or absolute defense the opponent deploys, he smashes through the physical matter and erases the concept itself with brute force.
