A low‑rank adventurer meets a dragon and wakes up as a skeleton. The Unwanted Undead Adventurer takes a familiar fantasy setup and turns it into something darker. The series, known in Japan as Nozomanu Fushi no Boukensha, has grown from a web novel into a full‑fledged anime that aired in early 2024. With a second season already announced, interest in Rentt Faina’s unusual journey continues to rise.
The story follows Rentt Faina, a veteran adventurer who has spent a decade hunting slimes and goblins for meagre pay. During an exploration of a labyrinth he stumbles into a dragon’s lair and is killed. Instead of dying, he reawakens as an undead skeleton – a “Bone Man”. Determined to keep his humanity and climb the adventurer ranks, Rentt sets out to find a way to regain his living body while hiding his new appearance from the world.
Produced by studio Connect, the first season of twelve episodes aired between January and March 2024. The anime adapts the light novel series written by Yū Okano and illustrated by Jaian, which began online in 2015. A manga adaptation followed in 2016, and both are still ongoing. The series has earned a moderate but loyal following, reflected in a MyAnimeList user score of about 7.43.

Where Can I Watch The Unwanted Undead Adventurer?
Is It on Crunchyroll?
Yes. Crunchyroll holds the streaming license for most regions outside Asia. The platform offers both subtitled and dubbed versions of all twelve Season 1 episodes. You can access the series through its official series page. Crunchyroll also reported the original anime adaptation announcement in 2022 and the Season 2 announcement in December 2024.
Is It on Netflix or Other Services?
As of early 2025, Netflix does not carry The Unwanted Undead Adventurer in any major region. Availability on other platforms like Hulu or Amazon Prime varies by country and has not been confirmed by the series’ official channels. For the most reliable access, Crunchyroll remains the primary destination.
Can I Watch for Free?
Crunchyroll offers a free, ad‑supported tier that includes the first few episodes of many series. However, full access to Season 1 and any future seasons typically requires a subscription. No legal free streaming option beyond that trial period has been officially announced.
Region availability can change. If you’re outside the usual Crunchyroll footprint, check local licensing announcements. The series is not currently listed on Netflix in the United States or Europe.
Will There Be a Season 2 of The Unwanted Undead Adventurer?
Official Announcement
Yes, Season 2 has been officially confirmed. Crunchyroll (via Anime News Network) reported the announcement on December 15, 2024. A teaser visual was released, showing Rentt alongside his companion Eel. The announcement included congratulatory messages from author Yū Okano, manga artist, and light novel illustrator Jaian.
Release Date Status
No release date has been announced. Neither a premiere window (such as a specific season or year) nor an episode count has been disclosed. Production is confirmed, but scheduling remains unknown.
What to Expect from Season 2
Based on the source material, the second season is expected to continue Rentt’s journey as he encounters stronger monsters, forms new alliances, and inches closer to finding a way to reverse his undead condition. The anime will likely adapt further volumes of the light novel, though the exact coverage has not been specified.
Official announcements are best tracked through Crunchyroll News and Anime News Network. Fan speculation on Reddit and Fandom wikis often circulates, but should be treated as unconfirmed until a reputable source publishes the information.
Is The Unwanted Undead Adventurer a Good Anime?
User Ratings
On MyAnimeList, the series holds a score of approximately 7.43 out of 10, indicating a moderately positive reception among the community. The score places it above average for seasonal anime but below the top tier. User reviews often praise the originality of the premise and the atmospheric world‑building.
Critical Reception
Professional critic reviews are limited, but the anime has been noted for its faithful adaptation of the light novel and its distinctive art style. Some viewers find the pacing slow in the first few episodes, while others appreciate the deliberate development of Rentt’s character. The lack of a major critical consensus reflects the niche appeal of the dark fantasy sub‑genre.
Why It Stands Out
The twist of remaining undead rather than being reincarnated sets it apart from most isekai and fantasy series. Rentt’s struggle to maintain his identity while hiding his skeletal appearance creates a tension that goes beyond typical monster‑hunting plots. The series also explores themes of perseverance and adaptation in a harsh world.
Some viewers who prefer fast‑paced action or power‑fantasy progression may find the first few episodes slow. The series rewards patience with deeper world‑building and character growth.

What Makes The Unwanted Undead Adventurer Different From Other Dark Fantasy Anime?
The series occupies a niche between traditional fantasy and the isekai genre. Unlike characters who are transported to another world or reincarnated with new powers, Rentt remains in his own world but is physically transformed into an undead. This forces him to hide his true nature while continuing his life as an adventurer. The focus on maintaining humanity while being treated as a monster offers a fresh perspective.
The anime adaptation by studio Connect has been noted for its atmospheric art and faithfulness to the source material. The world is built around a guild‑based adventurer system, with detailed monster lore and a sense of progression that rewards careful exploration. The pacing is deliberate, allowing viewers to experience Rentt’s gradual adaptation alongside him.
