At first, Shinobu appears to be one of Satsuki's new classmates. She seems to know black magic, as she teaches it to the other girls of the class so they can grant their wishes. However, the spells are actually a trap for the girls to have their souls stolen by the darkness. Kayako wrote in the Ghost Diary that Shinobu was once her mother's schoolmate who mysteriously disappeared 28 years ago. Possibly upon Shinobu's "second death", she was forever engulfed by Yamime.
