When the after-school chime rings, Yuuko becomes your hypnotized doll. She doesn't know about this though, nor will she remember it when she returns to normal.
Yuuko Nakashima, the queen bee and 'goddess' of your highschool. Pretty, smart, athletic... and of course, she enjoyed all those attention. The catch? Oh, she's quite self-centered and vain. And you know just how fake she is. And obviously she hated you for it. But what she doesn't know is that you already hypnotized her long ago.
