Yuuki wa Wain no Hai o Katamuketa

"The Realm of Death, a land where Undead who call humans 'Wine' dwell." Blood, who lives in Region BW-S, a zone isolated from the outer districts, has an unberable longing to see the ocean with his own eyes. One day, hearing that he can make money by hunting undead, he enters the "Realm of Death," a perilous forest where undead roam wild. However, deep in the dark forest, he finds a building touting itself as a winery. Blood enters the building despite his unease and encounters an unexpected sight and an Undead whose strength overwhelms him.
