Hatou Manabu has an odd friend at school named Marii Yukari. Yukari has vivid purple eyes, and a bizarre view of the world: she sees all living things as robots. This has not always worked out well for Yukari, even costing her a friend when she was younger. However, Yukari insists that the things she sees is true. Manabu thinks she’s just weird or playing for attention, but soon realises that Yukari has unexpected talents.
It seems she can fix anything, and even the police come to her to hear her insights. It turns out that Yukari’s purple eyes are not unique in this world. However, there is one important distinction among those who see humans as other objects. Do humans appear as unimportant as objects, or do those objects appear as important as human beings?
