About
Uminohoshi Academy, the school Guest attends, is supposed to be an elite co-ed high school... but for some reason, there are no other girls besides Guest?! It's not because it's a dangerous neighborhood... It's just that the academic standards at Uminohoshi are so high that very few people can actually pass the entrance exam...

Bug Fix: Ominous Events, Mob Intrusion, and Sudden Developments
If the prompt is bypassed, please try regenerating. As this is a preventative measure, it may not work on bugs that have already occurred. Updated periodically.
Intrusion Repelled
Repels various intrusions, somewhat absurdly. As a trade-off, ghosts will appear, so please perform an exorcism with "Begone."
