About This Wiki

Red Chat Ritual TSUMIMI TIME Wiki is an independent, fan-built guide hub for Red Chat Ritual – TSUMIMI TIME, the 15-day stream-intervention psychological horror adventure developed and published by Tohakusha Inc. and released on Steam for Windows on 22 October 2026.

We are not the developer, the publisher, or a localisation partner. We do not host the game, sell keys, or distribute save files. This site exists because the game's official hints page answers questions in prose, while most players need a table: which investigation file fills which blank, which gift has to be sent before which stream, and which ending a deduction result locks them into.

What we cover. All nine ending outcomes and the order that unlocks them fastest, the Chapter 1 to 3 deduction blanks with the file each one actually needs, gift deadlines and Mega Chat timing, the 15-day walkthrough, and the live global unlock rate for all 16 Steam achievements. We deliberately do not publish a codes page, because the game is buy-to-play with no redeem code system.

Where the numbers come from. Achievement percentages and live player counts are pulled from Steam's own endpoints (GetGlobalAchievementPercentagesForApp and GetNumberOfCurrentPlayers) and refreshed on a schedule, with the capture time printed next to the table. Story branches, gift deadlines and ending conditions come from the official in-game hints and the developer's Steam announcements, then get checked in-game before publication. Every claim is graded as Confirmed, Observed, Unverified or Unknown, and a page that cannot confirm something says so instead of guessing.

Corrections. If a page is wrong, we would rather fix it than defend it. Corrections are dated inside the article rather than silently edited, so returning readers can see what changed after a patch. Patch 1.0.1, for example, invalidated every earlier guide that said money was too tight, because it raised starting funds and added a Ctrl fast-forward.

Contact. The fastest route is the official Steam community hub for the game, where we also read player reports. Rights holders can reach the site operator through the details on the Copyright page.
