Kagura Tennouzu

Kagura Tennōzu (天王洲 神楽, Tennōzu Kagura) is the female protagonist and a student at the elite and prestigious St. Ignatius Academy. Raised as the heir to the powerful Tennōzu 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 as this will apparently cause her to stop producing the enzyme, not to mention Shinsen starves her to almost death. Even though Saiga doesn't acknowledge his feelings about Kagura, she has no problem expressing the fact that she wants to be at his side no matter what. When Saiga comes to terms with his feelings and Kagura sees how much he changes she often jokes about how "uncool" he's become, but nevertheless she still loves him. Before Saiga's fight with Suitengu he tells Kagura his feelings, which makes her very happy. Then tells Ginza to take Kagura to the island where Ryōgoku is, so he can treat her right away. After five years she returns to Japan to be at Saiga's side.
