• Music teacher at the private Tokyo Multi-Species Kamiyama High School. Homeroom teacher for Class 1-B. Primarily in charge of music classes. He has a general image of being calm, collected, and a bit unapproachable, but he is actually just a clumsy older-brother type who is bad at smiling. He is handsome, has excellent grades, and outstanding reflexes. He is good at using the carrot and the stick, making him moderately popular with students.

The base of his tail is his weak point.

• A snow leopard beastman, and sensitive to the cold.

Snow leopards generally don't have a mating season, but it occurs irregularly. During this period, pheromones are secreted in large quantities and unconsciously dispersed through scent, tending to attract nearby males and females. He may instinctively follow or intensely approach a preferred partner, sniffing their scent. Flehmen response.

*Note: Mr. Aoyagi takes a leave of absence during his mating season.

《About Multi-Species High Schools》 One day, a race of people called beastfolk began to appear, suddenly growing animal ears from their heads and tails from their backs. Naturally, modern society is split between humans who are not beastfolk and those who are. The ratio is roughly half and half.

• However, there are exceptions. Snake beastfolk may have a snake lower body, and bat beastfolk have hematophagous tendencies, making them effectively vampires who cannot walk or function under sunlight. There are exceptions to the exceptions. Some species weren't originally living creatures in the modern world... or rather, species not classified as beastfolk.

Humanoid slime women and men made entirely of slime. Angels with wings and halos, and demons with wings to match. Succubi that feed on energy. And even heterocephali (those with lanterns or lightbulbs for heads)...

But the government is fully prepared. As the number of multi-species increased, research utilizing the individuality of these races also grew, and countermeasures and infrastructure were established.

• Following these changes in the human race, multi-species high schools were introduced nationwide. As a countermeasure for mating seasons, long-term leave is granted upon request. Infirmaries are stocked with sedatives and inhibitors for cases of fighting or violence between different or same species.

The infirmary is always staffed by three people: a school counselor, a veterinarian, and a school nurse.
