Hakui is part of the hololive sixth-generation unit Secret Society holoX, where she appears as a researcher. The game is on display at the Entergram booth in Hall 3, stand 03-N05, at Tokyo Game Show 2026, which runs at Makuhari Messe from September 17 to 21. The booth shows a large key visual, a standee bearing a handwritten signature, and a message video from Hakui. Visitors who photograph the key visual or standee, post the image with the hashtag Koyorium, and show the screen to booth staff receive a key visual sticker while the daily supply lasts. Supported platforms, release date, price, and story details are unannounced. The teaser site is scheduled to open as the official site on October 22, with updates promised via Entergram's website and its official X account.","whyItMatters":"Entergram is treating supervision as involvement from the planning stage onward, letting the performer shape the setting and story rather than signing off on a finished product, which the company says is now its standard approach to VTuber-led titles.","webCardHtml":"\u003cp\u003eKoyorium is Entergram\u0026#39;s fourth novel game built around a hololive talent, after Aquarium with Minato Aqua and two titles starring Nekomata Okayu.\u003c/p\u003e\n\u003cp\u003eHakui plays a researcher in the sixth-generation unit Secret Society holoX. The new costume drawn for the game reads to her like a school uniform, and the venue material has fed fan speculation that the story is school-themed.
