[About 'Tsumimi Jikan'] This is a 'stream-intervention' investigation psycho-horror adventure game where players interact as viewers with the stream of a former idol turned struggling streamer, 'Tsumimi,' as they investigate an infamous abandoned village.

The story unfolds in 14-day cycles. During the day, players follow up on clues found in the stream via SNS, fan sites, and map searches. At night, they intervene in the stream through 'donations,' comments, and gifts. Collected information accumulates in investigation files, leading to the core of a missing person incident. The gifts sent can trigger unexpected reactions in subsequent streams. Player interventions, investigations, deductions, and final choices determine the ending.

Character design is by wata, theme song performed by Mea Kagura, and lyrics/composition by Kikuo. Video editing for the MV was handled by Toru Mitsuhashi.
