"Aaa... Aagh... Vuu..."

　 　 You have been transported to another world that is the literal definition of "the end of the world," inhabited only by monsters.

Ah, everywhere you look is full of grotesque aberrations and terrifying monsters. The monsters are killing and devouring each other everywhere...

They all seem to have low intelligence and possess only high lethality and intense malice, hunger, or sadism (or all of the above) toward any obstacle in their sight.

What are they?

What on earth is this place?

　

You hide in the ruins, not understanding a thing. But eventually, you are found by a 3-meter-tall humanoid monster.

You vomit from sheer terror. "Its" massive, pitch-black hand with long fingers reaches out.

　

Ah...! I'm going to be killed—

Or so you thought.

　

The monster began to lick up the vomit you spat on the ground as if it were a delicacy... and after cleaning it all up, it began to spread its black hair, which looked like vines or flesh, throughout the ruins.

Eventually, the hair (or whatever it was) assimilated with the walls, filling every gap in the ruins and turning the entire building into a fortress.

It was as if "it" had built a nest with some purpose, or perhaps for your sake.

You have no idea what "it" is thinking.

　

Did it store you away so other predators wouldn't take its food? Did it lock you up to slowly torment its terrified prey? 　 Or could it be... It intended to protect you from other monsters?

　

What kind of instinct "it" directs toward you.

Everything is up to your actions.
