The Unwanted Undead Adventurer’s 1st Main Trailer Reveals January 2024 Premiere, Previews Opening Song


The Unwanted Undead Adventurer anime adaptation has received its first main trailer and a January 2024 premiere window.

It was also announced that JUVENILE is performing the anime’s opening theme, “IMMORTAL,” while Mao Abe is singing the ending theme song. “IMMORTAL” is previewed in the trailer.

The Unwanted Undead Adventurer is based on the Overlap Novels fantasy light novel series written by Yuu Okano and illustrated by Jaian, which began publication in 2017 and has 12 volumes as of May 2023. J Novel Club describes the plot as:

Rentt Faina, a twenty-five-year-old adventurer, has been hacking away at monsters for a decade. However, without much talent for the job, Rentt finds himself stuck hunting Slimes and Goblins for meager amounts of coin every day. Little does he know, all this is about to change when he comes across a seemingly undiscovered path in the Labyrinth of the Moon’s Reflection. What awaits him at the end of the path, however, is neither treasure nor riches, but a legendary dragon that wastes no time swallowing him whole! Waking up a short time later, Rentt finds himself not quite dead, but not very alive either— He is nothing more than a pile of bones! Armed with nothing but his trusty sword, tool belt, and ghoulish new looks, Rentt sets off on his quest as a newly reborn Skeleton to achieve Existential Evolution, hoping to one day return to civilization with a more human form. Will Rentt succeed, or will the labyrinth consume him for the rest of his un-death…?

A manga adaptation by Haiji Nakasone began in 2017.
