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.
