Haruka Tomatsu, Shizuka Ishigami, composer Keiji Inai, sound director Jin Aketagawa

The second 2015 issue of Square Enix's Young Gangan magazine is unveiling on January 5 a key visual, additional cast and staff, and April premiere date for the Dungeon ni Deai o Motomeru no wa Machigatteiru no Darō ka? (Is It Wrong to Try to Pick Up Girls in a Dungeon?) television anime.

Haruka Tomatsu will play the half-elf Guild clerk Eina Chūru, while Shizuka Ishigami will play the human barkeeper Shiru Furōva. Jin Aketagawa will direct the sound, and Keiji Inai (Btooom!, Karneval, Nura: Rise of the Yokai Clan: Demon Capital, Outbreak Company) is scoring the music.

Fujino Ōmori began the original light novel series under SB Creative's GA Bunko imprint in 2013. The novel won the grand prize in the fourth GA Bunko Awards. The series has sold over 500,000 copies, and the novel has inspired three different manga series. Yen Press has licensed the novel series for English release in North America, and is releasing the first volume in December.

Yen Press describes the story:

In Orario, fearless adventurers band together in search of fame and fortune within the monstrous underground labyrinth known as Dungeon. But while riches and renown are incentive enough for most, Bell Cranel, would-be hero extraordinaire, has bigger plans. He wants to pick up girls. Is it wrong to face the perils of Dungeon alone, in a single-member guild blessed by a failed goddess? Maybe. Is it wrong to dream of playing hero to hapless maidens in Dungeon? Maybe not. After one misguided adventure, Bell quickly discovers that anything can happen in the labyrinth–even chance encounters with beautiful women. The only problem? He's the one who winds up the damsel in distress!!

The anime will star Matsuoka as the protagonist Bell Cranel, while Inori Minase and Saori Onishi will star as the "Loli deity" Hestia and the top-class female human adventurer Eyes Warenstein, respectively. Maaya Uchida will also star as Ririruka Aade.

Yoshiki Yamakawa (Hatsukoi Limited, Little Busters!) is directing the anime at J.C. Staff (A Certain Magical Index, Little Busters!), and Hideki Shirane (Date A Live, Bottle Fairy) is supervising the series scripts. Shigeki Kimoto (Sky Girls sub character design) is designing the characters for the anime, and GENCO is producing the series.
