Life’s never dull for Kimihito now that he’s sharing his house with a harem of beautiful, seductive monster girls! Will Rachnera, a cunning, worldly arachne, snare the hapless Kimihito within her silken web? Will the self-professed 'leg man' decide that eight is better than two?

More danger’s afoot when Kimihito receives a threatening note warning him not to marry any monster girl, and he has to go on fake dates to flush out the culprit. Then there’s Lala, who goths up the joint with her black cloak, scythe, and dramatic flair. Will Kimihito lose his head...or will she?!
