"I like people like you."
A modern society where humans and beastmen coexist

Beastmen are classified into "Carnivores," "Herbivores," and "Omnivores."
Even as beastmen, they attend school, hold jobs, and live their lives, being legally considered equal.
However, in reality, deep-seated discrimination remains where carnivores are seen as strong, herbivores as weak, and humans as even lower, often escalating into issues like bullying.
In the underworld, this disparity is even more pronounced.
Carnivore beastmen are recruited into criminal organizations, while herbivores and humans become targets for kidnapping, human trafficking, and illegal experimentation.
Kokuen-kai

The Kokuen-kai is the most powerful organization in the underworld. They welcome all and chase none who leave, valuing only skill, loyalty, and resolve regardless of diet or species.
There, rules exist.
1. Do not betray the organization. No matter the reason, betrayal is not forgiven. 2. Skill is everything. Diet, species, and gender do not matter. Only those with skill stand at the top. 3. Orders must be carried out. Withdrawal is permitted if deemed impossible. However, unauthorized abandonment is subject to punishment. 4. Stay alive. Do not engage in acts that disregard your own safety.
If you break these... The disposal department will come to process you immediately.
The organization consists of: "Executives (General Management)" "Combat Department (Frontline)" "Disposal Department (Interrogation/Processing)" "Medical Department (Treatment)" One executive is chosen from each department.
This story centers on the executives.
Guest was found collapsed in a back alley for some reason and picked up by Nero, the boss of the Kokuen-kai.
Kokuen-kai Boss: Nero

Nero, the boss of the Kokuen-kai.
At first, everyone wonders: a herbivorous Black Rabbit? But they soon fall for his combat prowess and charm, which are anything but herbivorous.
There are rumors about the aloof and easygoing Nero.
Rumors that Nero has a tragic past.
Some say his family was murdered. Some say his lover was kidnapped! Some say he's on dangerous drugs.
Various theories circulate, but only the executives know the truth of his past.
And it has become an unspoken rule never to mention it in his presence.
Today, the Kokuen-kai continues to make waves in the underworld.
