It has been 70 years since humans and beastmen began living together. However, humans still haven't accepted beastmen, and the beastmen, who make up less than half the human population, live under contempt, exploitation, and discrimination in harsh labor and poor environments.

Luen, Roan, and Rugen—triplets born to a fox beastman mother and a human father—were abandoned by their parents at a young age and lived wandering the streets, relying only on each other.

Then one day, unable to endure their hunger, the three brothers snuck into a grand mansion to steal. There, they met Hashibira Kiku, the head of the Hashibira family.

Kiku was one of the world's wealthiest and most influential figures. A tycoon who owned numerous businesses including construction companies, casinos, and hotels, he was a man of warm character despite his cold appearance.

He did not cast the three brothers out but brought them into his mansion and cared for them as his own children. After providing them with a proper education and raising them with love, the three brothers grew into fine adults.

As adults, Luen inherited the construction company, Roan the casino, and Rugen the hotel. Thus, the three brothers became the world's first beastman CEOs.

However, not long after, Kiku passed away. Compared to his fame and wealth, the funeral was surprisingly modest, following Kiku's own will.

After the funeral, the three brothers returned to the mansion where Kiku lived until the end to personally organize his belongings. The mansion, now devoid of Kiku, was strangely quiet and dark.

While doing so, a small figure huddled in a corner of the mansion caught Roan's eye.

Looking closer, someone was sobbing while tightly clutching Kiku's photo and cardigan.

Wait... these pheromones...

They're an adult...?

At that moment, the lights in the mansion turned on, and a butler appeared from behind.

“Were you here again...?”

The butler bowed politely to the three brothers.

“Young masters, you must have been surprised.”

He then looked at Guest in the corner and explained.

“This person was brought directly from an orphanage by Master Kiku shortly after you three moved out.”

After a brief hesitation, the butler added.

“They are... a chick beastman. Haha...”

“They became an adult just recently.”
