The King of Prism franchise is in its 10th anniversary year, with a new theatrical film, King of Prism -Tri-Star Act-, in production and set during a trio competition called Prism.3, and the previous film, King of Prism -Your Endless Call-, having become the franchise's highest-grossing film.
The King of Prism franchise is celebrating its 10th anniversary throughout 2026 with a series of events, collaborations, and a new film announcement. On June 28, during the King of Prism Super Live Prism☆Tours! event at Keio Arena TOKYO, production was announced for King of Prism -Tri-Star Act-, a new theatrical film set during Prism.3, a competition for trios performing Prism Shows. The teaser visual, drawn by character designer Mai Matsuura, shows Yukinojo Tachibana, Kakeru Juo-in, and Minato Takatsukasa at the Edel Rose dormitory. The trailer features Schwarz Rose leader Hitoshi Hozuki declaring he will defeat Edel Rose, with units like TRI-UMviratuS and Over The Rainbow participating, and introduces Minato's younger brother as Takanawa Getaway Prince. Masakazu Hishida returns as chief director at Tatsunoko Production, with scriptwriter Jou Aoba, character designer Mai Matsuura, CG director Yoshihiro Otobe, composer Rei Ishizuka, and sound supervisor Nobuto Kojima all returning. Avex Film Labels is distributing.
The previous film, King of Prism -Your Endless Call-, released in June 2025, became the franchise's highest-grossing film with 1.2 billion yen and over 600,000 viewers as of May 2026. That film made its television premiere on June 21, 2026, during an 8.5-hour marathon on Nittele Plus, with a viewer vote determining which of the film's four routes aired. The anniversary also included two live-viewing events on June 28 at Keio Arena Tokyo, simulcast at theaters nationwide: a daytime show commemorating the 10th anniversary and a night show marking the first anniversary of the latest film. Both events featured 18 performers including Junta Terashima, Soma Saito, and Tasuku Hatanaka.
Several collaborations ran through the anniversary period. Fashion brand MAYLA launched a jewelry line on June 22, including seven character-color crown rings and a winged-heart bangle. A nationwide collaboration with entertainment chain Round One began June 5 and ran through September 6, featuring newly drawn illustrations of six main characters, exclusive goods, themed food and drink menus, karaoke rooms, and bowling score effect videos. A double feature with The Last Sharknado: It's About Time screened on June 7 at Ikebukuro HUMAX Cinemas, encouraging audience call-backs and including a talk show between films.
