Made in Abyss (2012)

Nnaaa~~ I’m just a fluffy stuffed doll and I’ve come to console you two.

Don’t stay in the deep layers if you don’t want to kill those who are waiting for you.

Do you have a conception of God? The people around here, you see, don’t believe in God. Do you know what is it they believe in? The answer is this place - the Abyss itself.

Deep within it, the Abyss creeps into your mind. Eventually, it’ll get your body as well. Unlike the curse from the 6th Layer, those don’t manifest immediately. For every expedition, you’ll stand at the precipice of death and insanity, twisting the skin off your head.
