A plane crashes, and a monster drops from the sky and guts me!
When I open my eyes again, I've somehow returned to the moments before takeoff?
To stay alive, I deliberately cause a plane crash, only to be arrested as a lunatic!
That's right, I'm crazy!
I have dissociative identity disorder, but no one knows that the twelve personalities split off inside me are all reincarnations of gods and demons!
Calm, violent, frenzied... Every personality is a god of slaughter walking among humanity!
By day, I'm a lowly office drone, berated by my boss and fretting over medical bills.
By night, led by my yandere niece "Yaya," I slaughter my way through everything, becoming the S+ rank taboo known as the "Nest," something even the authorities can't classify!
While the whole world trembles beneath the shadow of nightmares, and a beautiful agent disguises herself as a meek little colleague to get close to me, I'm tearing apart the C-rank contamination source "Flesh Nest" with my bare hands, even invading the mind of a psychic agent!
"Hehe, Uncle is mine!"
Yaya smiles sweetly.
"Anyone who dares touch my toy, I'll kill for you, even if they're gods or Buddhas!"
But none of them know! Beneath this office drone's skin, besides the twelve personalities who can save the world, there lies a slumbering... ancient evil god, one even Yaya fears!
When it awakens, what will become of the world?
