Caim Kamui is a demon student in Babyls Demon School's Misfit Class. He resembles a small, owl-like creature standing 75 cm tall and weighing 10 kg, featuring a beak, wing-like hands, fluffy plumage covering his head and body, cat-like ears, and two small horns. He wears the standard Babyls male uniform accessorized with a blue cape and a demon-eye bow tie.
Kamui exhibits a dual personality: outwardly, he is polite and gentlemanly, using formal speech, yet inwardly, he harbors an obsessive attraction toward females. His behavior, including skirt-peeking attempts and unauthorized entries into female-only spaces, led to his Misfit Class placement. Believing gentlemanly conduct will make him popular with women, a notion influenced by his family history, he strives for this ideal. His ancestors once rebelled against the Demon King but later swore loyalty, pledging to uphold honor and etiquette. Kamui inherited his perverted tendencies from his father but was raised by his mother to embody gentlemanly behavior.
His unique Bloodline Magic, "Translation" (also known as "Friendship"), allows him to understand and communicate with any living creature, commanding them as allies. This magic embodies leadership, transcending language barriers. He excels at commanding birds and, through training, learned to control other students' familiars. Combat spells in his repertoire include *La Fire* (fire creation), *Libera* (projectile attack), and *Gran* (protective barrier). He possesses notable durability, enduring prolonged elemental magic assaults from teacher Momonoki during the Heartbreaker event. His magic proficiency and academic performance resulted in above-average exam scores, advancing his rank from Aleph (1) to Daleth (4) by the end of his first year.
Key school events include:
* Eliminating himself during the Execution Cannonball game by crossing enemy lines to peek under Elizabetta Ix's skirt.
* Assisting in the defeat of the Taurus Mountain Bull at Walter Park by using his Translation magic as a distraction.
* Partnering with Kerori Crocell for the Harvest Festival. Trained by Mister Hat in eloquence and animal command, they formed a "Beast Empire" to collect points, earning him a rank promotion.
* Being paired with Marianne Pheené and Uzu for the Heartbreaker exam, where he protected first-year students by commanding their familiars against teacher Momonoki. After collapsing onto Marianne’s lap, she defended him, marking a shift in their dynamic.
His relationships involve:
* Frequently harassing Elizabetta Ix, consistently facing rejection.
* Feeling jealousy toward Allocer Schneider for having a girlfriend.
* Forming an effective partnership with Kerori Crocell during the Harvest Festival, serving as her second-in-command.
* Earning initial disgust from Marianne Pheené, later tempered after his protective actions during Heartbreaker.
* Gaining respect from Alice Asmodeus for his manners, though Asmodeus regularly beats him up.
* Remaining unaffected by Iruma Suzuki’s female persona "Irumi," instinctively sensing it was male.
Trivia notes:
* His name and magic reference the demon Camio from the *Lesser Key of Solomon*, depicted as a bird-like entity granting animal speech.
* His family’s history of rebellion and subsequent pledge of loyalty influences his pursuit of gentlemanly conduct.
* A comedic trait involves him acting like a "real" gentleman when drunk, confusing his classmates.
