Four of Japan's most gorgeous guys have the impossible task of turning goth loner Sunako into a lady. When they find Sunako all dressed up and ready for a night on the town, the guys think their luck may have finally changed. Hoping to catch a glimpse of Sunako's date, the quartet follow her out the door. But instead of a handsome prince, they find an old granny with a taste for the macabre! Granny's Museum of Horrors is closing shop, and she's promised all of the remaining items to Sunako, her best (and only) customer. Just what the guys need: more gruesome artifacts cluttering their house. Sunako plans to bring her horrific treasures home, but the guys will do anything to stop her... even if it means all-out war.
