Plot
The "paranormal science" story follows nine idiosyncratic individuals, linked by the "Chōjō Kagaku Kirikiri Basara" occult summary blog run by 17-year-old second-year high school student Yūta Gamon. Little incongruities that occur around these nine eventually lead to a larger, unimaginable event that may alter what is considered common sense in this world.
