Kagura Tennouzu is a student at the elite and prestigious St. Ignatius Academy. Raised as the heir to the powerful Tennouzu Group, her bodily fluids contain an enzyme that has the ability to transform people infected with a mysterious virus into Euphorics (people with supernatural powers related to their innermost desires). She also has an inoperable brain tumor, causing her to only have six months left to live. Associates of Suitengu have given her injections to keep her from reaching puberty.
