During the Warner Bros. Japan “Stay Connected with Anime” panel at Anime Expo Lite, a new key visual was released for Is It Wrong to Try to Pick Up Girls in a Dungeon? (DanMachi) Season 3. The anime is scheduled for October 2020 after being delayed due to COVID-19.
J.C. Staff is in charge of the animation production.
Crunchyroll describes the show as:
Based off of a light novel of the same name written by Fujino Omori and illustrated by Suzuhito Yasuda, Is It Wrong to Try and Pick Up Girls in a Dungeon? is set in the world of Orario, where adventurers band together and look for treasures in an underground labyrinth known as Dungeon. However, for Bell Cranel, fame and riches are secondary to what he wants to find the most: girls. He soon finds out though, that anything can happen in Dungeon, and winds up being the damsel in distress instead!
