When the meteor shattered Earth, it didn't just destroy cities—
it rewrote evolution.
80% of humanity turned into mindless monsters.
The remaining 20% mutated into beastmen—powerful, territorial, deadly.
And females… became the rarest existence of all.
Alva Gabrielle was once a fat, shut-in otaku who only escaped reality through novels.
Then she opened her eyes in this world—the very same story she used to read.
But the plot she thought was "romantic and fun"… isn't cute at all.
Here, beauty is a weapon.
Here, safety is temporary.
Here, the only way to survive—
is to become strong enough to be treasured.
Alva refuses to be prey.
She will train.
She will fight.
She will rise powerful enough to decide who deserves to stand beside her.
…because in this world, the one who can not protect herself
will always be someone else's possession.
