Dungeon ni Deai wo Motomeru no wa Machigatteiru no Darou ka?, also known as DanMachi for short, is a Japanese light novel series, written by Fujino Omori and illustrated by Suzuhito Yasuda. SB Creative has published six volumes since January 2013 under their GA Bunko imprint. It has received a spin-off light novel series and three manga adaptations. An anime television series adaptation by J.C.Staff aired in April 2015.
Commonly known as the “Dungeon,” the city of Orario possesses a huge labyrinth in the underground. Its strange name attracts excitement, illusions of honor, and hopes of romance with a pretty girl. In this city of dreams and desires, new adventurer Bell Cranel has his fateful encounter with the tiny Goddess Hestia.
Thus begins the story of a boy striving to become the best adventurer and a lonely goddess searching for followers both hoping to reach their goals and perhaps have some romance in the side.
