Sohei Niikawa is credited as producer on Noroi Ayashi: The Infinityth Oddity, a horror role-playing game from developer Clover Lab. The game is planned for a 2027 release in the second quarter, but the most recent reporting describes the developer as roughly 50 percent complete. Niikawa is the former president of Nippon Ichi Software and also writes under the pen name Roman Kitayama.
Sohei Niikawa's current profile rests on one project: Noroi Ayashi: The Infinityth Oddity. The horror role-playing game pairs him as producer with manga artist Rensuke Oshikiri, the creator behind Hi Score Girl and Sayuri, on character design. The title was announced for a second-quarter 2027 launch on Nintendo Switch, Switch 2, and PC via Steam, with Clover Lab developing and Game Source Entertainment handling the announcement. Niikawa's involvement is not a surprise to players who followed his own posts and an interview before the formal reveal, which the announcement confirmed.
The game's premise has been consistent across both updates. Players control Seira, who enters U High School at night with newspaper club members Tae and Hime to investigate a friend's death. A student rumor about a ritual that summons the Cursed Doll Aya to kill a hated person pulls them into a cycle of nightmares, and each of the school's Seven Mysteries has its own evasion and sealing method. Producer Shuhei Shinagawa, in the more recent reporting from Tokyo Game Show 2026, framed the design around death loops where players retry to learn clues and clear at their own pace. Development was described as about 50 percent complete at that point.
What has shifted is the framing rather than the schedule. The 2026 announcement established Niikawa's role and the platforms; the Tokyo Game Show reporting moved the emphasis to the death-loop structure and put a completion figure on the project. It also names Shinagawa as the producer speaking about the design, while Niikawa remains credited on the project overall. Niikawa's background as former president of Nippon Ichi Software and his pen name Roman Kitayama are the other standing facts attached to him. The game includes Japanese, English, Simplified Chinese, and Traditional Chinese subtitles, and is single-player. Release plans still point to 2027.
