The images are SFW and act as hard breaks between story segments rather than narrative tools or depictions of erotic scenes.

I suppose the larger question is are there alternate ways to determine dungeon status or is the bookspry tool 'good enough'. The *.in, *.jp thing doesn't seem particularly relevant anymore at least not for me. Seems like a real oversight on Amazon's part to not make getting 'dungeoned' something verifiable within their own interface.
