Overview

Yeast is a crop unique to Wall Sheena, the innermost of the three Walls. Unlike weapons or gear, it plays a purely passive role in human survival: keeping stored food from rotting. Its existence is documented through the Currently Publicly Available Information notes accompanying the manga.

Function

Each batch looks like a mass of fermented soybeans about as big as a human head. Storehouses and tents pack these lumps in alongside soybeans, wheat, and dry-cured meats, and their presence dramatically slows how quickly those provisions decompose. Stranger still, the goods sharing storage with the yeast appear to be transformed by it in some way, through means that the science of the Walls cannot yet account for.

Notable Users

No individual character is tied to the crop. Its handlers are the food producers and storehouse keepers of Wall Sheena, where it is cultivated and distributed among the preserved goods that sustain the population behind the Walls.
