Synthesized from 4 Yomimono stories · updated Sep 13

In Falsus is lowiro's follow-up to Arcaea, and it is a different genre: a rhythm game built around the visual novel rather than a touch-screen note chart. lowiro announced the title on July 22, 2026, and released it on Steam for Windows on September 9, 2026. The game runs on a keyboard-and-mouse scheme, with six keys (Shift, A, S, D, F, Space by default) for the lower lane and the mouse for floating notes on the upper lane.

The setting is a near-future world where everyone wears a collar that reveals emotions and exposes lies. Five high school girls, each with her own problems, are forced to join a mysterious organization, and the story follows each girl through selectable routes. At launch the game includes more than 70 songs, over 40 of them original tracks written for it. Composers named in the coverage include REDALiCE, USAO, and Camellia; a music video for Camellia's 'Empty Shell' feat. Nano was released with the announcement. The voice cast includes Fuka Izumi, Ran Haruka, Kanon Amaki, Ayame Fujiue, and Miri Saito.

Between the announcement and the release, lowiro confirmed In Falsus would be playable at its Tokyo Game Show 2026 booth, alongside Arcaea, which received its Ver. 7.0 update on the same day as that August 29 news. Tokyo Game Show 2026 runs September 17 to 21 at Makuhari Messe. A demo was available on Steam ahead of launch, and a lottery campaign for autographed signboards from the five main voice actors ran on the official X account, with details announced on July 23.
