A 15-day psychological horror adventure where you intervene in an idol stream by day and night - and your deductions decide how her story ends.
Red Chat Ritual - TSUMIMI TIME is Tohakusha's psychological horror mystery adventure, released on Steam on October 22, 2026. You play as a viewer who watches Tsumimi's livestreams, sends comments, Mega Chats and gifts on a limited budget, and investigates the clues hiding outside the stream - searching social media, fan sites, maps and search results for keywords you pick up during broadcasts. This wiki covers the day-night investigation loop, the Mega Chat and funding system, the character roster, and the ending logic.
Use keywords learned during streams to search social media, fan sites, maps and search results. Replies and location details hide more than the top posts.
Comment, send Mega Chats and gift during the stream. Every line you send changes how the night goes - and what she remembers tomorrow.
Mega Chats and gifts cost money you do not have much of. What you spend on one night is money you cannot spend on the ending you need.
Your interventions, investigations and deductions decide the ending. Some endings only trigger after the stream ends and you wake up.
Red Chat Ritual - TSUMIMI TIME is a psychological horror mystery adventure developed and published by Tohakusha Inc. (η―η½η€Ύ), with CIRCLE LINE GAMES handling Chinese-region publishing. It was announced on April 9, 2026 and released on Steam on October 22, 2026. Its Chinese title is γηΊ’SCοΌεδΈΊεΆεηη₯εγ.
You are a viewer. Not a character in the room, not a police investigator - a viewer, sitting at home with a chat window, watching a struggling idol streamer named Tsumimi perform. Behind her partner and former duo member Mashiro has gone missing, and Tsumimi keeps streaming anyway, hoping that if she becomes famous enough, Mashiro will find her.
The structure is a 15-day cycle that alternates two activities. By day you investigate - searching social media, fan sites, maps and search results using keywords you picked up during streams. By night you watch the broadcast and intervene, using comments, paid Mega Chats and gifts, on a limited budget. What you do in the stream feeds back into the investigation, and your deductions feed into the ending.
Two practical notes. Saving before a stream matters - you can save and load from the home screen, and because streams branch on your choices, saving first is what lets you try different interventions to the same night. And hold Ctrl during a stream to fast-forward to the next Mega Chat choice. The game also ships an official Play Guide in Steam News and an official FAQ in the Steam Community hub - and the back half of that FAQ contains walkthrough spoilers, so read it deliberately rather than by accident.
During the day phase you use keywords learned during streams to search the outside world: social media posts, fan sites, map locations and plain search results. The official guidance is specific about where people miss things - check replies to posts and location details, not just the top result. Everything you gather is filed in the Investigation Files, which is your working notes screen and where the real deductions are assembled.
At night you watch Tsumimi's stream and choose how to act: comments (free but limited in effect), Mega Chats (paid highlighted messages that reach her directly) and gifts (the most expensive and most impactful). The game frames the three questions plainly: what will you say, when will you stay silent, and how will you use your limited funds?
The loop is not two separate halves. A gift sent late at night can trigger an unexpected reaction the next day, which changes what the daytime search turns up. Conversely, a clue you dig up during the day changes what is worth saying during the stream. Deduction is the act of noticing which night produced which clue, and endings are reached by connecting the fragments before it is too late.
A structural quirk worth knowing in advance: endings 6 and 7 only trigger after you finish the stream and sleep - the ending fires when you wake up. Several late-route endings are gated behind a specific Mega Chat on a specific day, with the choice text and its cost determining the route. Because of that, the ordering of your nights matters more than it first appears, and a run you think has ended may still have a consequence pending.
