Mercedes and the Waning Moon is officially heading to television, with its first teaser visual, trailer, cast, and production staff now revealed ahead of a January 2027 premiere. The anime adapts Firehead and KeG’s light novel series, which has also inspired a manga by Pochi Edoya and an English release through J-Novel Club.

For webtoon and manhwa readers, the announcement is notable because the series blends several familiar digital-comics ingredients—reincarnation, aristocratic family drama, dungeon progression, supernatural combat, and a heroine determined to build a meaningful second life—without reducing its premise to a simple power fantasy.
Mercedes Gets Her First Anime Spotlight
Anna Nagase will voice Mercedes Grünewald, the series’ young vampire heroine. The confirmed creative team includes director Kunihisa Sugishima, series composer Jun Kumagai, character designer Nami Ueyama, composers R・O・N and Shuhei Mutsuki, and animation studio Teddy.

The first trailer offers the clearest look yet at the anime’s visual direction, while the teaser visual places Mercedes at the center of the story’s moon imagery and gothic-fantasy atmosphere. No episode count, streaming platform, or more extensive cast list has been announced in the available official materials, so those details remain unconfirmed.
The January 2027 broadcast window was announced on July 15, 2026, through the anime’s official website. The adaptation was first announced in August 2025, making this new reveal the project’s first substantial presentation of its cast and staff.

A Vampire Aristocrat With More Than Survival on Her Mind
Mercedes and the Waning Moon: The Dungeoneering Feats of a Discarded Vampire Aristocrat follows Mercedes after she is reincarnated as the daughter of a noble vampire father and a socially shunned concubine. Her position is precarious from the beginning: she knows that her father may eventually choose another heir, while her mother and elderly maid have few resources to protect the household.
Mercedes therefore turns to dungeon crawling, a profession the story presents as accessible even to children. She begins training at an exceptionally young age, relying on her vampire heritage and the determination born from a previous life that ended without fulfillment. Her goal is not simply to become powerful. She wants to secure a future for her family and discover something that can make her “moon” full.
That combination gives the premise a more grounded emotional engine than the usual reincarnation setup. Mercedes is not chasing adventure because a prophecy demands it or because another world automatically grants her a comfortable life. Her motivation begins with housing, money, family, and the fear of being discarded—concerns that make the fantasy setting feel unusually tangible.
From Web Novel to Light Novel and Manga
Firehead’s story originally appeared on Shosetsuka ni Narou before TO Books began publishing it as a light novel series in May 2021, with illustrations by KeG. The supplied announcement reported three volumes as of February 2022, while TO Books’ current catalog lists the fifth novel volume as released on July 15, 2026.

The manga adaptation, drawn by Pochi Edoya, launched on TO Books’ Corona EX website in August 2021. TO Books’ catalog now lists six manga volumes, including the sixth volume released on July 15, 2026. That means readers approaching the anime have multiple versions of the story available, although the anime’s exact stopping point and adaptation structure have not yet been announced.

J-Novel Club licenses the series in English in both novel and manga formats. Its synopsis emphasizes Mercedes’ second chance at life, her family’s vulnerable position, and her determination to become a Seeker capable of earning a living through dungeon exploration.

Why the Adaptation Could Appeal to Webtoon Readers
On paper, Mercedes and the Waning Moon has the kind of structure that often works well in serialized comics. The heroine has an immediately understandable objective, the family conflict provides an ongoing source of tension, and dungeon exploration creates natural milestones for training, discovery, and escalation.
The story also appears positioned between several popular fantasy modes. Readers who enjoy villainess and reincarnation narratives may be drawn to Mercedes’ noble upbringing and inheritance anxiety, while action-fantasy fans have the dungeon system and monster encounters. The vampire setting adds a darker edge, but the central conflict remains personal: how can a child with limited social power protect the people who depend on her?
From an adaptation standpoint, the most important challenge will be balancing Mercedes’ vulnerability with her rapid development. A strong version of the anime will need to make her progression feel earned rather than treating her supernatural abilities as a shortcut. The emotional stakes surrounding her mother, household, and uncertain place in the family will be just as important as the battles.
That is also where the series may distinguish itself from more conventional dungeon fantasies. Its premise is not only about clearing floors or collecting rewards; it connects exploration to inheritance, class, family security, and the search for purpose. Those themes give the action a reason to matter beyond the next victory.
What to Expect Before January 2027
At present, the confirmed information is limited to the January 2027 release window, the first trailer and visual, Anna Nagase’s casting, and the announced staff and animation production by Teddy. Further details about the broadcast date, distribution, additional characters, music releases, and the anime’s episode structure have not been revealed in the available announcements.
For now, the series looks like a promising addition to the growing line of light novel and manga adaptations built around young protagonists navigating fantasy worlds through practical goals rather than destiny alone. If the anime preserves Mercedes’ mix of family anxiety, dungeon adventure, and second-life determination, it could attract readers who enjoy their supernatural action with a strong emotional foundation.
