AS ONE Anime Film Reveals New Trailer Ahead of Theatrical Release
Square Enix has released a brand new trailer for the upcoming theatrical anime film AS ONE. The film, which serves as a prequel to the 2018 arcade game Starwing Paradox, is set to begin its theatrical run in Japan on August 22, 2025. The latest trailer introduces key characters and teases major elements of the film’s storyline, setting the stage for an emotionally charged, high-stakes science fiction adventure.
Overview of the AS ONE Anime Film
AS ONE is produced by animation studios Honoo and StudioGOONEYS. The project is helmed by acclaimed director Kobun Shizuno, known for his past work on the Detective Conan film series and Godzilla: Monster Planet. Serving as a narrative bridge to Square Enix’s arcade title, the film delves into the complex world and characters introduced in Starwing Paradox.
The screenplay is a collaboration between Shatner Nishida, Kana Matsui, and Masaya Honda. Together, the writing team brings a nuanced approach to the dual narrative structure that ties modern-day Earth with the science-fiction universe floating far above in space.
Character and Mechanical Design Team
Character design is led by renowned artist Yoshiyuki Sadamoto, celebrated for his work on Neon Genesis Evangelion and Summer Wars. His distinct design aesthetic helps bring emotional depth and visual appeal to both the human and alien characters in the film.
Mechanical designs are handled by Ippei Gyoubu, whose previous projects include mecha designs for the Mobile Suit Gundam franchise. The complex machinery and futuristic warfare concepts in AS ONE are depicted with precision, underscoring the film’s high-octane sci-fi setting.
Story Summary
The narrative of AS ONE begins on present-day Earth, focusing on a high school student named Yoh. A passionate aspiring musician, Yoh is increasingly frustrated by opposition from his parents and interpersonal conflicts within his band. Uncertain of his future path, Yoh experiences a moment of disorientation when a mysterious voice calls out to him, saying, “Help!” Just then, he is engulfed in a dazzling white light at a bustling Shibuya intersection.
Meanwhile in outer space, a distant celestial body known as Meguriboshi orbits silently. A historic ceremonial truce is about to be held between two warring factions — the Va Led Sei Kingdom and the Ko Country A Slegga. Their long-standing conflict is fueled by the desire to control a powerful energy source called Hoshi no Chi, or “star blood.” Just as peace seems within reach, the scene is shattered by a catastrophic fall of orbital debris.
In the chaos, Vigo, a member of the Purugard team, scrambles to manage the falling debris. To aid him, Rako, a skilled robot mechanic, pilots an aircraft still undergoing maintenance. Her bold rescue attempt begins successfully as she manages to redirect the falling structure toward the ocean. However, the feat comes at great personal cost — her aircraft is heavily damaged, and Rako loses consciousness during the landing.
While unconscious, Rako’s consciousness intersects with Yoh’s, creating a bridge between Earth and space, past and present. The enigmatic connection between the two characters sets the stage for a story that explores identity, fate, and the interdependence of different worlds.
Music and Theme Song
The newly released trailer features a powerful theme song performed by RUKI, adding emotional resonance to the film’s atmospheric visuals. The music underscores the dual themes of internal conflict and external warfare, enhancing the audience’s immersion into Yoh and Rako’s intertwined journeys.
Confirmed Release and Availability
AS ONE is officially scheduled for theatrical release in Japan on August 22, 2025. Further details about international release plans or streaming platform availability have not been announced as of the latest press release. Fans of the original Starwing Paradox game will find this film to be a compelling expansion of the universe, with new characters and deeper lore that shed light on the conflict central to the game’s narrative.
Conclusion
With an experienced creative team, captivating story, and stunning visual presentation, AS ONE promises to be a standout addition to the 2025 anime film lineup. The newly released trailer offers the first deep look into the world-building and emotional arcs that define this ambitious project. Fans and newcomers alike will soon be able to witness Yoh and Rako’s extraordinary journey when the film hits Japanese theaters this August.
