About Red Chat Ritual – TSUMIMI TIME

The game puts players in the role of a viewer watching the live stream of "Tsumimi," a down-on-her-luck former idol turned streamer, and allows them to intervene as she investigates a rumor-shrouded abandoned village.

The story progresses over a 14-day cycle. During the day, players follow up on suspicious details spotted in the stream, tracking down information through SNS, fan sites, and map searches. At night, they intervene directly in Tsumimi's broadcast through superchats, comments, and gifts. All gathered information is stored in an investigation file, gradually connecting the dots toward a hidden past and the truth behind a disappearance case. Depending on what gifts are sent, unexpected reactions may surface in the following day's stream.

Players' intervention, investigation, deduction, and final choices will determine how the story ends.

Music video editing was handled by Toru Mitsuhashi, giving the song's world a visual form.
