In Japanese "Sakura" means "cherry blossom." She was once a very sickly girl who suffered from a variety of ailments. Many of them were the result of spirits that infested her body. On the advice of her uncle Cherry, she tried to exorcise Ataru, during which process, the demons who inhabited her transferred themselves to the unlucky young man. The second time she attempts to exorcise him, one of the demons possessing Ataru causes him to pounce onto her and suck her breast. Now in perfect health, Sakura is the Tomobiki High school nurse and a Shinto priestess or miko. Unlike her mother (who looks exactly like Cherry), Sakura is tall, slender and physically attractive, which makes her a common target of the lecherous boys of the school and even Mr. Onsen-Mark. The boys have been known to purposely injure themselves in order to see her. Like her uncle, she possesses an enormous appetite and has been known, despite never seeming to gain an ounce, to out-eat him. Sakura is extremely powerful and can summon foul and baleful creatures from Japanese folklore, by virtue of her mystical training.
