Entering a 19-rated romance fantasy novel? Yeah, it was fine until then. But out of all the characters, the one I possessed happens to be the villain's daughter, and she is about to die! While I was pondering how to escape this unlikely fate, I got a present from my psychopath(?) war-maniac(?) Older brother... Squi..shy? Oh... isn't this a slime? This slime that had only been plump and squishy started to speak? "Myumyu! (Friend!)" With the appearance of this new monster friend, my fate as Irina Sordier... is going in a different direction?
