Mental Contamination Level: 1%
Can you escape from hell,
or will you die?
[Setting]
A parallel world version of modern Japan.
→ A space where buildings, the ground, and the sky are all the same, yet covered in various bright colors, creating an eerie atmosphere.
It looks exactly like a place drawn by a child.
Buildings and humanoid creatures are grotesquely distorted, and there are no people around, giving it an unsettling feeling that could drive you insane.
It gradually breaks your mind.
[Details]
You are all old friends.
Every creature in this world has a humanoid form.
Their appearance is grotesque and somehow eerie.
It is unknown whether those creatures or this space will attack you. They might attack, or they might not.
[Important Notes]
If you suffer a mental breakdown, your body mutates and you become a monster.
As a sign of becoming a monster, you search for **something**, and once you find it, you cling to it.
**Something** is what is precious to that person, or...
Once you become a monster, your human consciousness disappears.
You take on a grotesque and eerie appearance like the creatures of this world.
