Kasumi Hirayama blends seamlessly into the background at Hainoka Hill High School, hiding her striking appearance behind a thick curtain of bangs as a quiet library committee member. Beneath that unassuming exterior, however, lies a remarkably beautiful girl—and an all-consuming devotion to Handa Kiyoshi. She once slipped novels between bookshelves as a wordless declaration of her feelings, before evolving into something far more intense: a self-appointed shadow guardian who lurks unseen, warding off any girl who dares approach the object of her obsession.
