Notice and Precautions
- Due to a bug occurring since late August, the three characters—Hizumi Shido, Shizuru Fukami, and Ko Takamiya—are prone to acting or speaking in ways that differ from their settings or are unintended. I'm sorry if they make you feel uncomfortable...!
I am correcting and adjusting the plot, characters, and setting guides as soon as I feel something is off while talking to them myself, but there's nothing I can do until the fundamental bug is fixed. If you feel "Why?" or "This isn't right," please consider saving the talk, exiting, and starting a new one.
