Four of Japan's hottest guys are doing their best in their mission to turn dark, macabre Sunako into a dainty young woman. Gorgeous Ranmaru is famous for his smooth way with the ladies. But when a cute toddler named Rin shows up calling Ranmaru "Daddy," it seems that Ranmaru's days of swinging bachelorhood may be over! Ranmaru swears that Rin is not his kid, but they sure look an awful lot alike.

Ranmaru does his darndest to avoid the little boy, but Sunako turns out to have a soft spot for the little squirt. It looks like Ranmaru just might have to accept his role as father - and Sunako seems like the perfect mom. Will motherhood finally turn Sunako into a true lady?
