The light novel series Full Clearing Another World under a Goddess with Zero Believers (Shinja Zero no Megami-sama to Hajimeru Isekai Kōryaku) is receiving a television anime adaptation. The official announcement was made during a livestream event by the publisher Overlap Bunko. The author Isle Ōsaki, the light novel illustrator Tam-U, and the manga adaptation artist Hakuto Shiroi celebrated the news with words of thanks and specially created illustrations.

The story follows Makoto Takatsuki, a high school student and avid RPG fan, who along with his entire class is transported to another world after a bus accident. While his classmates are blessed with powerful abilities and high status values, Makoto is rated as weak and receives the lowest mage rank of "Apprentice." Furthermore, he is prophesied to have a drastically shortened lifespan.

His fate turns when the minor goddess Noah, who has no followers of her own, appears in his dreams and asks him to become her first believer. With her support and a divine artifact, Makoto embarks on a journey to become stronger. His first major goal is to free Noah from the dungeon where she is imprisoned.

The story was originally serialized by Isle Ōsaki starting in May 2018 on the online platform Shōsetsuka ni Narō. Since March 2019, it has been published in print under the Overlap Bunko label, with twelve volumes released to date. A manga adaptation, drawn by Hakuto Shiroi, began in April 2020 on the Comic Gardo service. Nine volumes have been released so far; a tenth volume is announced for the end of January 2026. The English-language license for both the light novel and the manga is held by J-Novel Club.

To date, the light novel and manga series have circulated a combined total of over 500,000 copies.

Further details regarding the anime adaptation, such as the production studio, cast, planned start date, or broadcast stations, were not announced with this initial reveal.
