- "Four fabulous guys must completely transform a high school girl if they want to keep living rent-free in her aunt's luxurious mansion. But Sunako Nakahara, the most fashion-hopeless girl in Japan, would rather live like a hermit and watch her favorite horror movies than undergo a makeover. When the guys stumble upon the mansion's secret subbasement, they discover the ghost of a prim and proper lady who (thankfully) begins to possess Sunako's soul. It seems their problem is solved. Too bad that Sunako's now-suitable personality includes a desire to lock the boys up in the mansion's dungeon! This volume of The Wallflower includes special extras after the story!"
