A new teaser visual illustration and main cast announcement have been revealed for the upcoming Blade & Bastard TV anime adaptation. Warner Bros. Japan unveiled the new visual and trailer during its panel at Anime Expo 2025. A premiere date, staff, and studio have not yet been revealed.

The five main cast members, who are highlighted in the trailer, leading the series include:
- • Makoto Furukawa as Iarumas
- • Tomori Kusunoki as Garbage
- • Daiki Yamashita as Raraja
- • Saori Hayami as Ainikki
- • Shion Wakayama as Berkanan
The new visual is drawn by the original light novel illustrator so-bin. It is an updated version of an initial teaser visual that was released when the anime was first announced last October, this time revealing Raraja, Ainikki, and Berkanan.
The light novel series is written by Goblin Slayer author Kumo Kagyu and includes illustrations by Overlord illustrator so-bin. It has been published under DRECOM’s DRE Novels imprint since December 9, 2022 and has released five volumes as of June 2025. It also inspired a manga adaptation in June 2023, which Yen Press released in English print.

J-Novel Club simultaneously publishes the light novels in English digitally, and describes the main synopsis as:
Deep in the unexplored reaches of the dungeon, a corpse is discovered—one that shouldn’t exist. After Iarumas is resurrected, his memories of life before death are gone, and he spends his days delving into the dungeon to retrieve the bodies of dead adventurers. Can they be revived as well? Or will God reduce them to piles of ash on the altar? Either way, Iarumas collects his finder’s fee. And though his skills earn him some grudging respect, he’s also scorned for this cold, utilitarian attitude. The living keep their distance—Iarumas consorts primarily with the dead. That is, until he meets Garbage, a feral young swordswoman who’s the sole survivor of a massacred party. With Garbage by his side, Iarumas ventures deeper, scouring the dungeon for clues to his past, avoiding monsters, traps, and the inevitability of a permanent ashen demise.
