Grisiaia 15th Anniversary Mobile Game Stars Kazami Yuuji’s Future Daughters

Players hunting fresh Grisaia storyline will get a clear payoff: Frontwing and Good Smile Company announced a 15th anniversary mobile project, Grisiaia: Shuuketsu no Hyakka, set to release in Japan in summer 2026 and starring Kazami Yuuji’s daughters from the future. The reveal foregrounds time travel elements drawn from the original visual novel series, positioning familiar series motifs at the center of the new mobile experience.

Frontwing and Good Smile Company released an announcement video as part of the reveal. The title was presented explicitly as a 15th anniversary project for the Grisiaia franchise, and the announcement framed the mobile game around future-generation characters tied to Kazami Yuuji. The companies identified the project with the full name Grisiaia: Shuuketsu no Hyakka and confirmed the summer 2026 Japanese release window.

The creative hook for long-time fans is the inclusion of time travel elements from the visual novel series, which the announcement linked to the premise of Yuuji’s daughters coming from the future. That connection directly references narrative devices veteran players will recognize from previous Grisaia entries, and it places the new mobile title squarely in the franchise’s continuity rather than as an unrelated spin-off.

Development and release details remain limited beyond the companies involved and the seasonal window. Frontwing and Good Smile Company did not specify platforms beyond "mobile" in the initial announcement, and regional timing was listed for Japan in summer 2026. No pricing, gacha mechanics, or international release schedule were included in the reveal.

The project marks a milestone for the Grisiaia brand as a 15th anniversary celebration, with Frontwing and Good Smile Company steering franchise continuity into a mobile format that foregrounds legacy characters and time travel. Players in Japan can expect more promotional material and updates as the 2026 summer launch approaches.
