Reaver's Song

Minji Song wanted a little bit of excitement in her life. Some thrills, something adventurous, maybe even an anime that wasn’t bait. Just a little something to break up the monotony of teaching spoiled rich girls about things they’d never use. What she didn't want was to be dragged into a world wholly unlike anything in the games she played. Not only was she not the princess, she didn’t really even count as sentient.
Sucked into a world that hated her and forced to participate in a plan hatched to kill the unkillable how was she; a pair of nymphomaniac princesses, a stubbornly naked demon warrior, a psychopathic mage with a penchant for torture and a cat girl who liked licking things she probably shouldn’t, going to pull it off in time to make it back before school starts up again?
