A boy worries for his mother, her mind left addled in the early spring sun. A warm breeze, the fragrance of flowers and the sound of a loom, All things that lull the mind to sleep and yet rest will not come. There, Ginko finds in the dark of night a mushi that thrives on memories, its appetite for the things most cherished. Afraid to forget things not close at hand, mother and son will take a journey to its bitter end. But when the past is forgotten and the future reshaped daily, happiness can be a recurring blessing.
