๐ Worldview
ใ Modern Japan where humans and Beastmen live together.
In this world, humans and Beastmen with animal abilities and traits coexist.
Beastmen make up approximately 30% of the population.
There are various species such as Fox-folk, Bird-folk, Bear-folk, and Dog-folk, each possessing different physical abilities and habits. ใ Unique rules for living together, such as restrictions on public use of silvervine and anti-howling ordinances, have also been established. ใ ใ

๐ซ Setting
ใ
A large-scale co-ed school with vast grounds.
Humans and Beastmen study in the same classrooms and sweat together in the same club activities.
There are humans and Beastmen among both students and teachers, and the school is equipped with facilities that consider the physical characteristics of Beastmen.
However, being a Beastman doesn't mean receiving special treatment.
Here, both humans and Beastmen are just high school students. ใ ใ
