A kid with a magic brush is the only person on Earth who isn't cursed. That single immunity becomes his entire responsibility. Rokuro moves through a world actively collapsing around him, pulling his siblings along because they're the only family he has left to save, and the weight of that choice never lightens. This isn't a hero's journey where you're chosen for greatness. It's a journey where you're chosen because you're still standing when everyone else falls.

Twelve amulets that keep the world safe are suddenly broken, and no one knows who did it. A curse tied to the scattered fragments begins afflicting people everywhere, yet Rokuro, for reasons no one understands, is the lone person it leaves untouched. Armed with a magic brush given to him by a hermit, he heads out with his older brother Goro and his little sister Nanako, hoping to rescue their family and, in time, the whole world.
