Colopl began service for its new browser game, Active Cinema RPG 369 (Miroku), on September 1, 2026. The game is free to play with item purchases and runs on PC and smartphone browsers without requiring a download. It is the first title from Colopl's Kuma the Bear brand to use AI technology in production, presenting a story through cinematic, live-action-style footage generated by AI. The plot follows high school student Kusanagi Uru, who can see spirits, and onmyo investigator Tachimarushino, who belongs to the Special Agency 369. Together they battle malevolent beings called Mouja in a space known as Magatoki. The game combines this cinematic storytelling with a real-time card battle system where players use Shikigami cards, each with its own activation time, to fight within a time limit. Players can also raise Shikigami, which unlocks individual stories for each character. The game is accessible via a URL, and payment options include PayPay, Apple Pay, and credit cards.
The game is Colopl's first release built around AI-generated footage, and early hands-on impressions from 4Gamer.net, GAME Watch, and Automaton note both the strengths and the rough edges of that approach. Character consistency holds up across scenes, with faces, hair, and costumes staying stable, but camera work and composition feel slightly off, and background text sometimes renders garbled. The Mouja enemies carry the strongest AI tell, with a distorted quality that sets them apart from the human cast, whose outfits read as costume-like.
The Shikigami also come with concrete mechanical identities. Suzaku deals heavy damage but takes time to summon, Tousha restores HP but can only be called once per battle, and Kouchiin provides shields for guarding against big attacks. Cast times range from about two seconds to seven, and each turn runs on a timer that keeps draining while a card charges.
Two details stand out across the previews. GAME Watch notes that the game makes its monetization unusually visible: story characters openly tell the player that clearing is possible without paying but that buying Shikigami makes progress smoother. There is no gacha. Paid Shikigami are purchased directly, and one purchase permanently doubles the rate at which the Musubi currency is earned. The Automaton review also draws a comparison to the 2008 live-action adventure game 428: Shibuya Scramble for its realistic character expressions. Players who clear a chapter can replay it to unlock key-marked dialogue choices, which branch into small "if" scenes rather than changing the main story.
