Snackgirls react
Kirari: The first key visual is the part I want to linger over. A visual novel starring Koyori has plenty of room to turn her familiar image into a distinct game aesthetic.
Nea: Her supervisory role makes me curious about which parts of Koyori’s personality will shape the project. October’s full-site opening should give that question more context.
Entergram has announced Koyorenium, a visual novel built around hololive Virtual YouTuber Hakui Koyori. Her involvement extends beyond the lead role: she is also supervising the project.
The first visual is here
A teaser site and key visual offer the first official look at the game. The full website is scheduled to open on October 22, 2026, making that the next confirmed information milestone rather than the game’s release date.
Major game details remain under wraps
Entergram has not announced the platforms, release date, price, or synopsis. Route structure, romance elements, voice coverage, and gameplay systems are also unknown, so the starring-and-supervision role remains the clearest indication of the project’s direction for now.
