Red Chat Ritual: TSUMIMI TIME Demo – What You Can Play

The TSUMIMI TIME demo is a playable slice of Tohakusha's psychological horror adventure in which you act as a viewer in idol streamer Tsumimi's livestream, spending money on messages and gifts and building a case file of clues. A demo ran at the Tohakusha booth at BitSummit PUNCH in Kyoto, May 22–24, 2026, according to Gematsu's launch-date report, and the build has since circulated as downloadable demo gameplay. As of 2026-10-17, the official Steam page lists a release date of October 22, 2026 and states that save data from the demo cannot be carried over to the full game.

What the demo lets you do

The demo is effectively chapter one. It runs on the same day-and-night structure as the full game: you investigate and work during the day, then intervene in Tsumimi's nighttime stream through comments, Mega Chats, and gifts. Clues you gather go into an investigation file, where connecting them moves the story forward.

A demo playthrough video, “Red Chat Ritual – TSUMIMI TIME Demo Gameplay (Tip To Guide The Streamer)”, shows the loop in practice. The player character works shifts for money, reads Tsumimi's posts and fan-site material, and saves highlighted keywords to the investigation file. At night, the stream becomes the main event: you choose what to send and how much to spend.

The demo is short by design. That same playthrough shows the demo closing out its chapter after about six in-game days.

Practical tips for a first run

• Money is a soft gate. The demo player notes you cannot do everything in one day and repeatedly hits the limit of what you can afford to send. Treat spending as a choice, not a checklist.
• Not every stream moment needs a Mega Chat. In the same video, the creator points out that staying silent is sometimes fine and that over-intervening can go badly — one branch gets the viewer blocked from the channel, triggering a game over. Sending nothing is a valid move.
• Investigate during the day. The night stream is mostly about watching and intervening. The daytime windows are where you pick up keywords and connect them.
• Watch the wish list. Gifts and requested items tie into later stream events. The demo video's author speculates that failing to help Tsumimi get what she needs may lock out some content, though this is their reading of the demo rather than a stated rule.
• No save carryover. Since demo progress does not transfer, there is little reason to grind for a perfect file — use the demo to learn the rhythm and the kinds of deductions the game expects.

What the demo does not tell you

The demo does not include a formal tutorial. The video's author spends much of the run working out the day-night structure, money management, and the difference between useful and harmful interventions by trial and error, and says plainly that a short in-game explanation would have helped. If you feel lost early, that is a common experience with this build rather than a sign you missed a menu.

The build also does not spell out how heavily each intervention feeds into endings. The video's author suspects that which keyword you pick up and which request you respond to can steer later events, and notes that endings branch on your choices — but the demo itself does not confirm specific branch rules.

How the demo relates to the full game

Several details in circulation are about the release version, not the demo. Gematsu's report describes a roughly two-week day-and-night cycle; the official Steam page describes a 15-day adventure and estimates about 4 hours for a first playthrough and 8–9 hours in total for multiple endings. The Steam page also notes that replaying shared scenes may be necessary when chasing multiple endings. Treat demo pacing as a sample, not a forecast of total length.

The demo circulated at BitSummit PUNCH in May 2026 and as downloadable gameplay footage afterward. Its exact public build number is not something the material above establishes, so mechanics described here reflect what playable demo footage shows rather than a specific version identifier.
