Mushi-Shi S02 E11 Cushion of Grass

"The cure lies in the curse."

After his encounter with Nui and before becoming a mushishi, young Ginko moved from place to place, due to his condition of attracting mushi. At one point he found himself instructed and cared for by a mushishi named Suguro, in the lands of a dying Mountain Lord. Ginko wonders about his place in the world and the natural order, as Suguro worries that the new Mountain Lord hasn't yet appeared.
