A bright and energetic young girl, Ran is introduced to her supernatural powers right along with her first year in junior high school. While she is troubled by her powers seeming to instigate ill fortune upon people in contact with her and illuminating their ill intentions in some cases, Ran soon learns to accommodate her supernatural abilities and accept herself as is with the support of her family and peers. Accompanied by Rui, Ran finds herself constantly embroiled in mysterious circumstances and events whose resolution requires that she learn to collaborate with Midori (another girl who also has supernatural powers).
