Forgotten death
Apart from his name, Shiori hardly remembers anything from his life, nor does he know why he died. Even when she tries to end her life again, she still cannot leave this world. Therefore, reclaiming her memories and understanding her lingering obsessions became the goals she pursued together with the player.
Investigation and Conclusion
Players talk to different ghosts, collect urban legend encyclopedias and other archives, and then use options in the story to advance investigations. The work features multiple endings, and choosing may cause the journey to end prematurely; The total reading process provided by the developers is about ten hours.
Modes of expression
The show combines ghost comedy with horror performances. The built-in mode can change the color of blood, making it convenient for readers sensitive to visuals or live streams, but it does not remove death descriptions or horror scenes from the text, so content changes are mainly on the visual level.
