The world has fallen.
Three children, John, Ember, and Josh lives in an underground shelter along with 17 other children. Their guardians, Father and Mom, train them for The Outside. However, there's something wrong with the shelter- No, something's wrong with everything.
If you like Promised Neverland, this is something you can look forward to. There's a lot of mystery and intrigue surrounding this story, its caretakers, and the strange artifacts left all around the house. Looking forward to the coming chapters!
