Yen Press’s Yen Audio imprint has previously released audiobook adaptations of series such as Solo Leveling, KonoSuba, and Overlord, among other titles.
Here are the details for each new audiobook release:
Yami-hara

Story: Mizuki Tsujimura
This audiobook is set to release November 2023, and it will be the first horror audiobook released under Yen Audio.
Synopsis:
The strange kid at school, the odd woman in the apartment building, the troublesome man at work. Such people exist everywhere, in everyone’s lives. All it takes is a word for it to start. An unsettling question, a bizarre remark, or even a kind apology. Once their hooks sink in, the cracks form. Darkness floods into the recesses until nothing else remains, and then…Sirens, screaming, dull thuds on the pavement. They have always existed. They just are. And when they show up, people die.
Goblin Slayer

Story: Kumo Kagyu
The audiobook edition is set to release November 2023.
Synopsis:
A young Priestess joins her first adventuring party, but blind to the dangers, they almost immediately find themselves in trouble. It’s Goblin Slayer who comes to their rescue—a man who has dedicated his life to the extermination of all goblins by any means necessary. A dangerous, dirty, and thankless job, but he does it better than anyone. And when rumors of his feats begin to circulate, there’s no telling who might come calling next…
Is It Wrong to Try to Pick Up Girls in a Dungeon?

Story: Fujino Oomori
The audiobook series is set to release November 2023.
Synopsis:
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!
