Yuta Okkotsu is a nervous high school student who is suffering from a serious problem—his childhood friend Rika has turned into a curse and won't leave him alone. Since Rika is no ordinary curse, his plight is noticed by Satoru Gojo, a teacher at Jujutsu High, a school where fledgling exorcists learn how to combat curses. Gojo convinces Yuta to enroll, but can he learn enough in time to confront the curse that haunts him?
Nikuko is a brash, jolly, scattered, and passionate woman in an otherwise sleepy seaside town in northern Japan. She’s also the single mother of 11-year-old Kikuko, who is her opposite in many ways. Kikuko is a string-bean of a young girl, pensive, quietly curious, and methodical in how she approaches life in this small harbor town. Nikuko embarrasses Kikuko as any mom of a preteen would, but Nikuko’s bold spirit makes her especially well-known in a town where Kikuko herself wants nothing more than to simply blend in. As Kikuko navigates the everyday social dramas of middle school, enhanced with touches of magical realism from her ever-present imagination, a shocking revelation from the past threatens to uproot the pair’s tender relationship.
