The Promised Neverland (2019)

Nestled within a forest and protected by a gate, Grace Field House appears to be a serene orphanage where children thrive under the watchful eye of their nurturing caretaker, Mama Isabella. While daily tests are a norm, the kids enjoy playful freedom—though they must never stray too far from their home. A dark cloud looms over their idyllic life, as each few months, a child is adopted, vanishing without a trace. It’s the eldest trio who begin to unravel the sinister truth behind their existence and the shocking reality of their seemingly loving Mama.
