A flyer from this year's AnimeJapan 2017 event revealed on Thursday that the television anime of Fujino Ōmori and illustrator Kiyotaka Haimura 's spinoff light novel series Is It Wrong to Try to Pick Up Girls in a Dungeon? Sword Oratoria ( Dungeon ni Deai o Motomeru no wa Machigatteiru no Darō ka? Gaiden: Sword Oratoria ) will get 12 episodes. The anime will premiere on Tokyo MX , KBS Kyoto , Sun TV , BS11 , and AbemaTV on April 14 at 24:30 (effectively April 15 at 12:30 a.m.).

The project serves as the 10th project to commemorate GA Bunko 's 10th anniversary.

Youhei Suzuki ( The "Hentai" Prince and the Stony Cat. , Urara Meirochō ) is serving as the show's new director at J.C. Staff . Writer Hideki Shirane , character designer Shigeki Kimoto , and composer Keiji Inai are returning from the original anime. Yuka Iguchi is returning to perform the opening theme song "RE-ILLUSION," and Kano will perform the ending theme song "day by day."

GA Bunko describes the anime's story:

Sword princess Aiz Wallenstein. Today, once again, the strongest female swordsman heads to the giant labyrinth known as the "Dungeon" along with her allies. On the 50th floor where mysteries and threats such as a decayed dragon's corpse that crumbles to ash and an irregularity that creeps ever closer to the party loom, Aiz calls for the wind and heads deeper into the darkness of the Dungeon. Eventually, she finds herself meeting a boy for the first time. "Um, are you OK?" In the Labyrinth City of Orario, the contrasting stories of the boy and the girl intersect!

Yen Press is releasing the novel series in English, along with the original Is It Wrong to Try to Pick Up Girls in a Dungeon? light novel series and the Is It Wrong to Try to Pick Up Girls in a Dungeon? manga adaptation.
