Every hero starts with power. He started with dust.One moment, the classroom buzzed with teenage chatter. The next, silence fell. Students blinked—and opened their eyes in an ancient hall carved from gold and marble. The air shimmered with divine magic. And at its center stood a goddess—flawless, proud, unbelievably beautiful and wrapped in flowing white.It was a divine summoning performed by a divine goddess.Among them was Vritra… and his stunningly beautiful mother.While others received blessings, powerful physiques and grand titles, Vritra was given a skill so pathetic it made even the goddess wrinkle her nose. An ability—so pitifully weak that it drew laughter, scorn, and even disgust. But that wasn't the worst part.Betrayed and cornered inside the labyrinth, Vritra had two choices: die… or fall into the death trap.A death canopy with no exit and no chance of survival, the only option was to slaughter the demons endlessly for months.Finally!! He forced his dormant skill to awaken, after killing thousands and hundreds of thousands demons and devouring them, becoming a broken ability.******White robes. Cold arroganceA sinful revenge.White robes can stain. And in the dark, even divinity can moan.And then there was his mo— guilt in her breath, shame in her eyes, whispering apologies between gasps in her son's ear, doing what had to be done… for both their sakes.

He rose from abjection and achieved eternity in glory.
He embraced the prettiest beauties and killed the strongest opponents.
He was able to shift the clouds into rain and cover the sky with one hand.
He could overrun the entire world and go anywhere as he pleased.
He pacified wars and held the world in awe.
He was matchless in the world.
However, his hair turned white overnight for his beloved woman and he was on the verge of death.
He was surrounded by enemies who were trying to take his life.
He struggled his way to become mighty and fought for everything he cherished.
For this age, he was the only king of the Dark World.
His name was a byword for might.
As a man living in the world, his only ideal was to pursue brilliance.

Alex is a normal girl in a post-apocalyptic world of monsters. The remaining pockets of humanity now coexist with tamed creatures that defend their towns from existential threats beyond the edge of the map.Then a Mark appears on Alex after a unique encounter. Now she can transform herself using monster essence! But the more she changes, the further from human she drifts.Join Alex as she becomes stronger, assembles her allies, and eventually founds a clan to fight for dominance of the region!It takes a monster to fight a monster, and someone has to breed them.Slightly interactive with periodic CYOA votes.This is an obvious parody with a semi-serious tone, lots of monster sex, a futanari protagonist, and a growing harem of monsters (mostly girls with a few exceptions).WARNING, Alex is bisexual and there will be both male and female monster species. If any of that isn’t your thing, move along.All characters are +18 including the monsters, who are sapient with the ability to consent. Some scenes have villains committing acts of sexual violence, but there will be no non-consensual sex scenes with the protagonist.
