When there's trouble afoot in ancient China, it's up to the Sisterhood of Steel to set things right once again. So, when a spell is cast on Kashin, the beautiful Han official, that begins to slowly turn her into a cat, it's up to Rybi and the others to go forth and find the exotic ingredients to undo the enchantment before the felinization is finalized. And there'll be no time for pussyfooting around; at least Kashin certainly hopes there won't be, because this is just the beginning of an even greater plot launched by a band of evil eunuchs. (Though, given what they are, it's not as if they have much to do besides plot, and who can blame them for being a little ticked off?) Get ready for the wildest epic fantasy to ever combine panties, cat girls and elephant belly button lint in the same storyline as the ferociously all-female force from Koihime Mus? and Shin Koihime Mus? returns in their usual fine fighting form in Shin Koihime Mus? : Otome Tairan!
