The wait is finally over for fans of the fantasy isekai series A Wild Last Boss Appeared. The anime has revealed its first main trailer, confirming an October 2025 release and unveiling more of its magical action, iconic characters, and production team. The adaptation is being helmed by director Yuya Horiuchi, with animation by Studio WAO World. The trailer comes months after a teaser visual introduced the Twelve Heavenly Stars and now brings more detail to the high-stakes world of Exgate Online, where the story unfolds.
The newly released trailer is backed by the opening theme song titled “Level o Agete Butsuri de Naguru” performed by Kisida Kyodan and The Akebosi Rockets. Known for delivering high-energy themes, the band’s involvement adds excitement to an anime already loaded with tension and spectacle. The visuals highlight the series’ central protagonist, Lufas Maphaahl, as she returns to a world that once feared her rule. Also featured are members of the Twelve Heavenly Stars including Dina, Aries, Libra, Aigokeros, Parthenos, and Virgo.
Leading the voice cast is Ami Koshimizu, who takes on the role of the formidable and mysterious Lufas Maphaahl. She is joined by Yuri Usui as Dina, Yukina Shuto as Aries, Hisako Tojo as Libra, Naoya Uchida as Aigokeros, Mika Kanai as Parthenos, and Kokoro Omori as Virgo. With a strong ensemble of characters, the series aims to blend mythical grandeur with emotional stakes.
The production team features seasoned names in the anime industry. Yuya Horiuchi serves as director, with Kazuyuki Fudeyasu handling series composition. The original character designs were created by Yahako, with Maiko Ebisawa leading the character design for the anime. Sub character designs are being managed by Takashi Kobayashi and Shota Ueno. WOWMAX is producing the series, and the entire animation is being executed by WAO World.
A Wild Last Boss Appeared is based on the light novel series written by Firehead and illustrated by YahaKo. The story originally began on the Shosetsuka ni Naro web platform in 2015 and was later picked up for print by Earth Star Entertainment. Although both the light novel and its print publication concluded in 2019, the story has lived on through a manga adaptation by Tsubasa Hazuki, which is still ongoing and available through Comic Earth Star. English-speaking audiences can also enjoy the story, as both the light novel and manga are licensed by J-Novel Club.
The anime follows the story of a man who suddenly finds himself inside the world of an MMORPG, reincarnated as his in-game character Lufas Maphaahl. Once a fearsome tyrant who ruled as the leader of the Twelve Heavenly Stars, Lufas vanished during a major player-driven event. Now, two hundred years later, she awakens in a reality where her name remains a legend, and the world is no longer a game. Lufas must navigate this new realm filled with uncertainty, seeking to uncover what happened during her long absence and confront the threats that have emerged in the aftermath of her fall.
With a compelling blend of dark fantasy, action, and character-driven storytelling, A Wild Last Boss Appeared looks ready to stand out in an already competitive fall anime lineup. As the trailer teases both visual spectacle and emotional weight, fans of isekai adventures and MMO-inspired narratives should keep their eyes firmly on this title.
