What is Tsumimi Jikan?

Tsumimi Jikan is an innovative psychological horror adventure where players intervene with the streams of a struggling former idol named Tsumimi. The story unfolds over a cycle of 14 days. During the day, players gather clues by observing discrepancies during streams and utilizing various platforms to search for additional information. At night, players can influence the stream through donations, comments, and gifts. The information collected contributes to an investigative file that gradually links to a mysterious disappearance case. Depending on the gifts received, the streamer may react in unpredictable ways, deeply integrating player choices into the unfolding narrative.

Character designs are by the talented artist Mako/wata, while the theme song is performed by the incredible Kagura Mea, with lyrics and composition by Kikuo. This combination promises to link the musical piece to the broader game experience, enhancing the immersive world for players.
