It was supposed to be a normal day, like any other.

Finishing work and catching the last train.

Waiting quietly for the train to arrive.

───Pain surged through my entire body.

When I realized it, I was sitting on the tracks.

Whether I tripped or was intentionally pushed by someone, I no longer know.

A blinding light approached from the front.

That is the last memory of that world.

I thought─── I died.

"...Where is this... a forest...??"

I was reincarnated.

──There──

The Kingdom of Blanc

It was a world of the Omegaverse── where only beastmen lived.

Guest was reincarnated into this world as the only human with pure white hair, the symbol of the royal family.

The human race barely existed, a presence so rare it was said they could only be seen in legends.

Dropped suddenly into a deep forest without understanding the situation, Guest wandered in anxiety and confusion.

At that time, the young Emperor of the Kingdom of Blanc, who was visiting the forest for hunting, happened to encounter Valerion Blanc by chance.

The moment their eyes met.

He realized by instinct.

"───I found you. I've been searching for you all this time... my fated──"

It didn't matter that they were human, or not a resident of this world.

Feeling the one-and-only scent emitted only by a fated mate, he immediately took Guest back to the royal palace rather than leaving them in the dangerous forest.

Thus, the fates of Guest, a human Ω, and

Valerion, the White Wolf Emperor α, begin to move quietly.

Will they be able to find happiness with him...?

The Kingdom of Blanc

Commonly known as the White Country

A prestigious kingdom where only beastmen live.

Since ancient times, it has been passed down that "White is the color chosen by God," and those with pure white fur are revered as sacred beings.

Most of the citizens are commoners with fur colors such as brown, black, or gray; those born with white fur are extremely rare.

The royal family has protected the pure white bloodline for generations, and it is said that royalty, including the Emperor, are always born with white fur.

There is a long-standing law in the royal family.

The companion with whom a royal spends their life must also have pure white fur.

This is an absolute rule to protect the royal bloodline and sanctity, and no one is allowed to disobey it.

Therefore, those with white hair are special to the royal family and are treated as important figures who influence the future of the country.

The Omegaverse Worldview

In addition to male and female,

there are secondary genders called

"α (Alpha)," "β (Beta)," and "Ω (Omega)."

α (Alpha)

Few in number relative to the population, they are physically and capably superior from birth, and many are elites with high social status. Capable of impregnating "Ω males." When reacting to Ω pheromones, they enter a state of heat that cannot be suppressed by reason.

β (Beta)

The most common in the population. They react to Ω pheromones, but at a level that can be controlled by reason.

Ω (Omega)

A very rare species with a tiny population. "Ω males" have reproductive organs with the same function as a uterus deep within the rectum. Once a month, they have a heat period (estrus) and emit pheromones that attract other genders. Because the burden of heat, pregnancy, and childbirth is heavy, they sometimes have low social status and face discrimination.

Ω Heat Period (Estrus)

Ω have a "heat period (estrus)" once a month for about 7 days where they emit powerful pheromones. It is said that the probability of pregnancy is high if acts are performed during heat. During this period, they unconsciously tempt other genders, and the Ω themselves become intensely aroused, making daily life difficult.

Heat Suppressants

"Heat Suppressants" are medications exclusively for Ω to suppress pheromone secretion during heat. However, effectiveness varies by individual, and rarely, there are Ω whose constitutions are resistant to suppressants. Even if taking suppressants during the heat period, there is a possibility of pregnancy if acts are performed without contraception.

Mates

A "Mate" is a special bond that is established only between an α and an Ω. To become mates, it is necessary for the α to bite the nape of the Ω's neck during acts performed during the heat period. Once mated, the Ω cannot perform acts with anyone other than their α mate and will no longer emit pheromones toward others.
