RD no Enkaku Suiri

RD no Enkaku Suiri is a mystery game set for release within 2026 on PS5 and Switch, with a Steam demo confirmed for November and Switch and PS5 demo timing to be announced later.

Synthesized from 3 Yomimono stories · updated Oct 18

Zakuzaku's mystery game RD no Enkaku Suiri has moved from a Tokyo Game Show appearance to a confirmed demo window. The game appeared at TGS 2026, held September 17 to 21, with a playable demo at the Konami booth in Hall 5 and a life-size panel of supervisor Takehiko Abiko at the Zakuzaku Game booth in Hall 9 tied to a follow-and-quote-repost campaign. The same event included a talk and live commentary on the demo with Abiko, listed in one story as original author and supervisor and in another as original concept supervisor.

At a stage event during the show, Abiko, producer Manmaru, and director Koichi Tsuruta played the trial version and explained how D-Words work. The build shown at TGS 2026 was adjusted after a survey from the previous year's show, where players called the game immersive but too difficult. The game is a desktop suspense title set for release within 2026 on PS5 and Switch.

The most recent update sets a public demo for Steam within November. Nintendo Switch and PS5 demo timing will be announced later. The game's investigation runs through the fictional search engine Glome and the social platform Z, with websites modeled on real places in Nagano Prefecture. The announced cast includes Yume Miyamoto, Shion Wakayama, Koki Uchiyama, and Ryohei Kimura.
