Death and Taxes.
The two insurpassable laws of the universe.
So long as humans exist in this world, these things will remain.
However, there is a 3rd law which has always, and will always implement itself on people.
Reincarnated in a new world, five people are forced to learn this the hard way.
Placed on 'Nightmare mode' and being reincarnated as monsters, they are forced to survive under incomprehensible conditions.
However it is only through suffering, that we grow as people.
And it is only through suffering, that we truly become monsters.
"Nightmare mode.... eh? Tell me, what exactly was this mode supposed to mean again? Were our lives supposed to become nightmares?"
Without suffering, there is no change in anything.
"Or were we supposed to become the nightmares?"
This is the story of the antiheroes.
