Besides knowhing this author's love for some very dark stuff and all, i wouldn't be surprised that if they won't leave, they'll face a whole night of nightmare fuel of japanese survival horror tier of which i doubt they would surive, maybe like Kuon or something...
After reading pool #462 this comment is now extremely hilarious in hindsight.
TheodoricBlood said: No, they're a group of chicks who inflict death and abuse upon yukkuris for being the plague that they are, as simply looking at the pictures would have told you.

Hilarious now, given that although the label is usually identified with Sanae types, it applies more to Reimu types with how yukkuri are portrayed in fandom.
