Hestia (Japanese: ヘスティア Hepburn: Hesutia?) is a fictional character who appears in the light novel, anime, and manga series Is It Wrong to Try to Pick Up Girls in a Dungeon? by Fujino Ōmori, or DanMachi for short. The series is set in the fictional world of Orario, where people join groups called Familia run by gods and goddesses, who serve a range of functions from dungeon crawling to crafting items. Hestia herself is the head and resident deity of the Hestia Familia (ヘスティア・ファミリア?), a small and initially lowly group whom at first contained only herself and protagonist dungeon explorer Bell. After failing to recruit anyone into her group, and Bell being unable to join any of the larger, more reputable Familias, the two join forces thus beginning their adventures in the series.
Hestia has become an extremely popular and somewhat of a breakout character in anime and manga fandom. She has also appeared in several official DanMachi related merchandise, and has been the subject of positive reception, with critics focusing on her relationship with Bell, attractiveness, and role in the series. She has also become a popular subject of cosplay, causing a trend in Japan where women attempted to replicate her iconic costume.
