Ryouko (了子)

"Hey... Tomorrow, you're going to die." Minazuki Satsuki, 16 years old. By all accounts your average 2nd year high schooler, apart from being a social misfit always declaring her classmates' impending deaths. They've nicknamed her Usotsuki (Liar) but her eyes are special indeed. What she sees with them is.. The grand return of Ryoko-sensei, author of Shi ni Aruki! For every death (question), there must be a reason (solution)

A wealthy man, Kurosu Tokimune, meets an unnatural end. With his death, his family joins together to grieve, only to become suspects of a police investigation as to whether he was murdered. Their primary suspect: the adopted daughter of the Kurosu family and first to discover his body, Kurosu Tokiko. The girl who shows no distress at her father's death. And as all suspicions point to her, the second unnatural death occurs... It's always been this way. Wherever Tokiko goes, people tend to die.
