Reimu swore; she should have realized that these two would be consumed by the lust of this place.  Just like she was about to, if she didn't get out of there fast.  The captives wouldn't be much help, that was for sure, but she couldn't just leave them as they were.  She came to a quick compromise; she grabbed her dagger and cut through the first girl's bonds, freeing her arms.  If they were at all focused on escaping, she'd be able to free both of them soon enough.  If not... well, she could come back for them later today, after sating her own lusts someplace safe.  Turning to leave, she grabbed a few of the imp's satchels before running back through the cave as quickly as possible, planning to quick walk back to her camp as soon as she was able to.
