Game Source Entertainment announced Noroi Ayashi: The Infinityth Oddity, a horror role-playing game developed by Clover Lab., inc., with a launch planned for Nintendo Switch, Switch 2, and PC via Steam in the second quarter of 2027. The project pairs manga artist Rensuke Oshikiri, known for Hi Score Girl and Sayuri, with producer Sohei Niikawa, the former president of Nippon Ichi Software who also writes under the pen name Roman Kitayama. Players control protagonist Seira, who enters U High School at night with newspaper club members Tae and Hime to investigate a friend's unexplained death. There they test a student rumor that a ritual summons the Cursed Doll Aya to kill a hated person, and the act pulls them into a cycle of nightmares. Each of the school's Seven Mysteries has its own evasion and sealing method. The game includes Japanese, English, Simplified Chinese, and Traditional Chinese subtitles, and is a single-player title.
A trailer and teaser visual accompanied the reveal, and Game Source Entertainment opened the Steam store page to take wishlist registrations.
Niikawa's involvement was visible months before the formal announcement. In February 2026 he posted on X under the Roman Kitayama name that he had started scenario work on a new title, listing it after Etrange Overlord and Demon's Night Fever as still unannounced. A March 2026 Game*Spark interview had him reveal only the genre names of four projects in development, and one of them, "time loop horror RTA stealth action adventure," matches the genre line in the Noroi Ayashi product listing. Game Source Entertainment gives the same label to the game.
Oshikiri's own catalog runs alongside the news. He launched Hi Score Girl in Square Enix's Monthly Big Gangan in 2010 and ended it in September 2018; the manga ran in English through Square Enix Manga & Books and inspired a TV anime that premiered in Japan in July 2018 before Netflix streamed it overseas that December. His sci-fi adventure Geniearth ran in Akita Shoten's Weekly Shonen Champion from September 2021 to July 2022, and Titan Manga released the first English volume on April 14.
