Kagerou Daze, Vol. 2 Manga

Momo Kisaragi has a problem. She has to be the center of attention. In fact, she can't get people to stop looking at her. But when a chance encounter leads her to discover the strange truth behind her eye-catching ability, she's thrust into a deadly hostage situation that's far more than she bargained for--and that's before she runs into her shut-in brother, Shintaro!
