In a surprise announcement at Anime Expo 2026, Sekai Project has announced its upcoming localization of Jewelry Heart Academia (Jewelry Hearts Academia -We will wing wonder world-), with a release window of 2026.
This visual novel is a highly-rated title by Cabbage Soft, the developer behind titles such as Amairo Chocolate, Amazing Grace -What color is your attribute?-, and Sakura no Kumo * Scarlet no Koi, with elements of fantasy and intrigue. And of course, some rather cute animal-eared demi-humans. It includes a scenario by Fuyuakane Tom and character designs by Shiratama. The other title in the series, Jewelry Nights Arcadia -The ends of the world-, has not been announced at this time.
In addition, shortly before their panel, they released a demo for Akaneiro ni Somaru Saka by feng, which you can find on Steam. While QA work is still in progress, Sekai Project has reiterated its intended release window of 2026 for the full title.
Finally, they’ve announced a Sekai Project x Frontwing New Merchandising Collaboration focusing on characters from the original Grisaia trilogy, which Sekai Project helped to crowdfund back in 2018.
