The series takes place in 1989.
- Considering that three years take place after 1983, and 1986, it's more than likely that the visual novel takes place in 1989.
Higanbana probably will be uncanceled after R07 finishes Rose Guns Days
- Depending on how long Rose Guns Days is, we can expect Higanbana The Third Night in a few years... or not.
There will be an anime adaptation of the visual novel.
