Didn't see another thread for this, maybe it was mentioned in the What are You Reading thread? I'm pretty sure I found it through this forum. Maybe my search-fu just sucks.
Mostly just curious about others' opinions on this series. I enjoy it. Feels like some blend of Eden: It's an Endless World and The Promised Neverland, for whatever that's worth.
The story is set in two distinct worlds. Tokio lives with other children inside a world surrounded by a beautiful wall, but one day he receives a message that reads, "Do you want to go outside?" Meanwhile, a boy named Maru travels with an older woman, eking out a meager existence in a ruined world as they search for "paradise."
