Red Chat Ritual launches with a stream-driven horror mystery
Red Chat Ritual – TSUMIMI TIME turns livestream comments, investigations and deductions into a 15-day psychological horror mystery.
Red Chat Ritual – TSUMIMI TIME, a psychological horror adventure about intervening in a streamer’s broadcasts, is now available on PC through Steam. Developer Tohakusha released the game on 22 October, with a launch discount running until 6 November. 1
The game places players in the role of a viewer trying to uncover what happened to Mashiro, a missing former partner of the streamer Tsumimi. Rather than simply watching events unfold, players can influence the broadcasts through comments, Mega Chats and gifts, then follow leads beyond the stream through fan sites, social media, maps and search results.
How the investigation works
The story is organised around a 15-day cycle. During the day, players investigate suspicious details and connect information gathered outside the stream. At night, they return to Tsumimi’s broadcast and decide how to intervene. Limited funds add another layer of pressure: every comment, gift or Mega Chat can affect what happens next, while the deductions made from scattered clues can change the story’s outcome.
That structure gives the release a clear identity beyond its horror styling. Tohakusha describes it as an adventure built around stream intervention, investigation and deduction, with multiple endings shaped by player choices. Steam lists the complete experience as a single-player adventure and warns that it contains psychological horror, violence, blood, and references to self-harm and suicide. 2
The release follows a demo period and arrives with the title’s English name, Red Chat Ritual – TSUMIMI TIME, on the Steam store. The Japanese presentation remains part of the game’s identity, but the store listing confirms English interface and subtitles alongside Japanese, Simplified Chinese and Traditional Chinese support. The game is designed for a broad range of PCs, with minimum requirements including Windows 10 64-bit, 4GB of memory and a GTX 750 Ti-class graphics card.
Our opinion
The premise is timely because it treats livestreaming as more than a visual backdrop. The stream is the place where the player makes immediate choices, but the investigation only becomes meaningful when those choices are connected to evidence found elsewhere. That combination should appeal to players who enjoy mystery adventures where the route to an answer matters as much as the final reveal.
It is also a more focused proposition than a sprawling horror game. A 15-day structure, limited resources and multiple endings give the investigation a defined rhythm, while the warnings around its subject matter make clear that the cute streamer aesthetic sits alongside heavier themes. The result is a launch worth watching for anyone interested in games that turn online performance, audience behaviour and detective work into their core mechanics.
