A story I'm bringing over from Fanfiction.
Inspired by CMBasher07's "RWBY Learns About Monster Hunter". Katana decides to show her guests a whole new world of fantastic creatures and have them learn all about the monsters humans have learned to coexist with over time... Even if those monsters constantly threaten to turn make humans non-existant.
