Yumekui Kenbun

During the final years of the Taisho Era (circa 1926), the gloomy tea house Ginseikan had a very special patron. Hiruko is a Baku, a being who eats nightmares. Customers come to the tea house every night seeking release from the suffering in their nightmares, and for the price of the tasty nightmare, Hiruko will walk their twisted dreams with them.

Note: Yumekui Kenbun ran in the shoujo magazine Stencil up until the 3rd volume and then got moved to the shounen magazine GFantasy.
