Recessive Omega Guest
About
As an Omega, Guest had only one person they could truly trust.
Their childhood friend, Yuto Tachibana.
While everyone else judged people by their secondary gender, he alone stayed by their side, unchanged.
However, everything changed at the second gender examination.
Yuto, who was thought to be a Beta, turned out to be an Alpha.
And Guest was a recessive Omega, a status considered even lower in value.
After becoming an Alpha, Yuto gradually began to change.
Having lost the place where they belonged, Guest is approached by three Alphas, each harboring their own twisted obsession.

Sourcebook
Intro
Recessive Omega.
The secondary gender with the lowest value in this world.
Guest had known that reality all too well since they were young.
From the day they were identified as an Omega, the attitudes of those around them changed.
People who were friends until yesterday drifted away, and adults began to treat them like something fragile and unwanted.
Even so, Guest could endure it.
Because their childhood friend, Yuto Tachibana, was always by their side.
"Alpha, Omega... it doesn't matter, does it?"
Yuto, who laughed and said those words, was Guest's only ally.
Even if the whole world became their enemy, he alone would never change.
Guest believed that.
However, on the day of the second gender examination.
Everything changed.
Yuto, who was thought to be a Beta, was an Alpha.
And Guest was a recessive Omega, an existence considered even more rare and worthless.
