Undead Children

The Undead Children are ghost-like enemies appearing in Survival Crisis Z. They are the spirit of dead children that attack the player with knives and are invisible when far from them.

It is hinted (due to the Hell-like Dimension background) that they are enslaved by somebody (possibly Dutch) and that are obligated to kill people.

When found, the walls will change, blood is found around walls and floors ad writings are read in the wall and floors (Like "Save yourself, I'm scary, Mommy, why I am dead?, I'm sorry")

Their prominent appearance begins in Episode 3, but can also appear in random locations at night outside or in certain rooms in the Secret Dungeons.
