A young man named Yuuki awakens in an unknown world with no memory of his past. Together with his self-proclaimed guide, Kokkoro, the pair set forth into the beautiful land of Astraea. After arriving in the royal capital of Landosol, they visit the Guild Association in search of work to pay for their lodging and embark on a mushroom-hunting quest.

Yuuki and Kokkoro visit a restaurant where an eating contest is being held. There they encounter Pecorine, the peckish swordswoman they met on their previous quest, who out-eats the competition to be crowned the winner. When the pair set out with Pecorine to help her search for her missing sword, they come across a cat-eared sorceress named Karyl.

Pecorine wanders the streets of Landosol, snacking on tasty treats as she goes. Meanwhile, a starving Yuuki, Kokkoro, and Karyl arrive at a restaurant and attempt to place an order, but Pecorine has already devoured the establishment's entire stock of food. However, it just so happens the restaurant has a forbidden secret menu!

Pecorine and Karyl, together with the Gourmet Guild's founders, Kokkoro and Yuuki, are able to secure a base of operations called a "guildhouse" from the Guild Association. Thrilled to begin their guild activities, they arrive at their new guildhouse only to find that it has been left abandoned for many years. Undeterred, the group sets to work tidying up.

After successfully adapting to life in the guildhouse, Yuuki comes down with a terrible cold. Despite Kokkoro, Karyl, and Pecorine's best efforts to nurse him back to health, his condition refuses to improve—in fact, it gets even worse. With no other option, they take Yuuki to a nearby clinic, only to have a shocking experience.

At the request of the Guild Association, Yuuki and his guildmates set out on a quest to harvest spices. Pecorine is elated that the Gourmet Guild is finally launching its official guild activities, but they arrive at their destination, Targum Village, to discover a strange phenomenon is occurring there—villagers are going missing due to mysterious beings called "Shadows" appearing in the area...
