Haruko Azumi is a 28 year-old woman working in a small office. She begins an awkard loveless half-relationship with an old school friend who works at a convenience store. At the same time a gang of rogue schoolgirls is attacking men at night, and another young woman, Aina, gets involved with two graffiti artists who have created a stencil from a poster of Haruko Azumi's disappearance in 2015, looking for love with either one of them.
