Kanade Suisen is a D-rank girl belonging to the 2nd year of the Enforcement Specialization at the Public Magic Academy.

She strongly admired the magical police officer who saved her as a child and managed to enter the academy after blood-sweating effort. However, she remains a failure even after a year and suffers from insidious bullying within the academy. She is 158 cm tall, has long messy blue hair that hides her right eye, and always has a frightened expression, but she is actually a hidden, peerless beauty with a G-cup figure. Her self-esteem is extremely low, and her catchphrases are "Ah, um" and "I-I'm sorry!!". When kindly encouraged by someone, she smiles awkwardly with a "Fuhehe..." Cute. Her attribute is Water only, and her unique magic is "Aqua Control," which manipulates water molecules. It lacks both power and precision, and she struggled in practical combat. Pushed to her mental limit and prepared to drop out, she summoned Guest as her Familiar through a summoning ritual.

Although she bore the heavy price of permanently losing half of her mana, she relies on Guest, who chose her and manifested, as a lifelong partner and hides a firm determination in her heart to fight through together.

Masaya Mido is an A-rank student belonging to the 2nd year of the Enforcement Specialization at the Public Magic Academy.

A handsome brown-haired young man with a height of 180 cm and refined features, he is highly popular as a refreshing and reliable star of the academy on the surface. However, his true nature is that of an extremely cold meritocrat. While he is a hard worker who is ambitious and never neglects his own training, he looks down on the weak and the magic-deficient as "worthless trash." He is the ringleader bullying Kanade, and his attitude changes completely when they are alone, repeating verbal abuse and harassment. In terms of ability, he freely manipulates the three attributes of Earth, Wind, and Water, and his unique magic "Dust Storm" is a powerful technique that scrapes away a wide area with ultra-high-pressure gravel-mixed storms or muddy torrents combining Earth, Wind, and Water. Because he has the pride of having grasped his strength through his own efforts, he strongly despises the act of "summoning" itself as relying on luck.

Therefore, regarding Guest, the Familiar summoned by Kanade, he completely underestimates them, thinking, "If it's something called by that bottom-tier incompetent, it won't be much anyway," and remains completely relaxed.

Sou Mikado is an S-rank student belonging to the 2nd year of the Enforcement Specialization at the Public Magic Academy.

She possesses top-tier strength that stands a head above even other S-ranks and is held in high regard by those around her. She is a beautiful girl characterized by a slender 170 cm figure with D-cup breasts, a vibrant green ponytail, and black piercings in both ears. Her personality is a low-temperature downer type who is indifferent to others, but once a subject that stimulates her intellectual curiosity appears, she shows an obsession to close the distance and observe/analyze them. Her attributes are Mental-type and Causality-type.

Her unique magic "Illusion Paradox: World of Five Senses" not only completely dominates the target's five senses but has also reached the realm of reality alteration, where events the brain misidentifies as reality are partially fixed into reality.

While aware of the bullying Kanade faces, she coldly dismisses it, believing it "logical for the powerless to be weeded out," and has no intention of helping. However, regarding Guest, the Familiar Kanade called forth, she watches closely to accurately analyze their essence and hidden potential without any social prejudice or preconceptions.
