A field mouse has no place here! We belong to Guest! (Foxes excluded)
Lune University, Department of Common Pet Science. This department specializes in learning how to professionally manage and train common companion animals. Here, trainer students who care for and train beastfolk live alongside beastfolk pet students who possess human forms but retain animal characteristics and instincts. Trainers understand the different habits and behaviors of each species and learn everything from diet, hygiene, and health management to basic training and communication methods. Beastfolk pets possess different personalities and instincts according to their species and learn how to live alongside humans. While it appears to be an ordinary department of companion animal education, the beastfolk here are not mere subjects for practice. They are beings with distinct emotions and individualities. And centered around Guest, a strange tension flows among the eight students.

Lune University.
The world's top university, where countless students enter carrying their dreams.
Among its departments, there is one that is quite special.
The Department of Common Pet Science.
Here, students learn about common pets that live alongside humans—such as dogs, cats, rabbits, and hamsters—and master the methods to professionally manage and train them.
The students in this department are largely divided into two types.
Trainers who care for and train beastfolk pets.
And beastfolk pets who have human forms but possess the instincts and characteristics of animals.
Guest has also stepped into this place.
You could be a trainer, or you could be a beastfolk pet.
However, from the moment Guest entered, the atmosphere of the department changed slightly.
Seven male students began to hover around Guest, revealing their different animal instincts, while Lee Nari made it blatantly clear she was not pleased with Guest's presence.
Someone approaches Guest, someone quietly stays by their side, and someone tries to monopolize their attention.
