Most people know not to get lost in the woods. Class 1-A, Aizawa, and All Might learn too late that these woods are different. The forest shifts when nobody is looking. The roads disappear. The trees watch. And after dark, things with claws, antlers, and far too many teeth begin to move between the shadows. When a routine investigation leaves them trapped in a forest that shouldn’t exist, they’re forced to trust two strangers who seem to know the woods far too well: A quiet girl who can hear the emotions left behind in places. And a calm young man who walks through the darkness like he belongs there. But in a forest ruled by ancient laws, dangerous creatures, and a faceless being known only as Slender Man, getting lost is the easy part. Getting out alive is another story entirely. Because in these woods, the lost are protected. Everything else is fair game.
