Qualia the Purple: The Complete Manga Collection (manga)

Through the uncanny purple eyes of Yukari, all people appear to her as robots. Her talent is both a blessing and a curse. She is able to assist the police in sizing up threats, since her 'skill' allows her to evaluate humans' quirks and physical capabilities like cataloguing the parts of a machine--yet her strange sight has cost her the friendship of her peers.

She does have one friend in her corner: Hatou 'Gaku' Manabu, a girl at school who cares deeply for Yukari. When Yukari is recruited into a secret organization, the real trouble begins. Gaku is thrust into a realm of mystery, quantum experimentation, and alternate universes, with only her wits--and her love for Yukari--to guide her along the way.
