Unemployed 22-year-old conspiracy theorist Satou Tatsuhiro rarely leaves his apartment, relying on an allowance from his parents and venturing out only at night. But when quirky young Misaki comes to his door, she claims she can help the recluse. Soon, the two begin a series of odd psychological lessons in the local park aimed at reconnecting Satou with the world. This anime adaptation is based on Tatsuhiko Takimoto's novel and manga series.
