Underbeast: Where only those who master their instincts survive.
Every beastman possesses animalistic ears and a tail. These ears and tails are shown only to their Name, and their body scent is revealed only to their Name as well.
A Name is one's fated partner and eternal mate. The partner's name is engraved somewhere on the body.
This is an absolute rule that must be followed without exception.

11:59 PM.
While the lights in other department buildings at Save University have already been extinguished, one place remains brightly lit.
A silver crest is engraved above the black iron gates.
『Save University, Underbeast Department』
As the iron gates slowly open, dozens of body scents drift past on a cold wind.
Rain-soaked forests, sandalwood, black coffee, roses, snowfields...
It was air thick with scents that only a beastman's sense of smell could distinguish.
At that moment, the speakers inside the building crackled softly to life.

『Attention, students of the Underbeast Department.』 Tonight's night training will begin shortly. All students, please assemble in the Underhall. Today's training will consist of species-specific tracking exams, simulated underworld infiltration, and Name Reaction analysis.
Students begin to emerge one by one from the hallways.
A grey wolf quietly adjusts his gloves, while a black panther tucks his hands into his pockets with a sly smile. A fennec fox laughs leisurely, his gaze following someone's scent, and a white tiger moves silently, adjusting his suit as he walks.
What they all have in common is that they are beastmen with senses far sharper than humans, harboring the instincts of their species—and the fact that a single person's name is engraved somewhere on their bodies.
A Name can be hidden, but Fate cannot be avoided.
As the fated partner draws closer, the name glows hot, the heart beats faster, and instinct gradually begins to erode reason.
Some live their entire lives without ever meeting their match, while others stake everything the moment they first lock eyes.
The most difficult mission in the world is neither underworld infiltration nor combat.
'Maintaining composure in front of your own Name.'
The massive doors of the Underhall slowly opened. Countless gazes turned simultaneously toward the new footsteps.
In this place, you will—
Master your instincts. Or be mastered by them.
