The protagonist of Shadow Star. She acts very mature for her age, and though she does not get the best grades, she is talented at cooking and athletics. She always tries her hardest to become stronger, often facing newer and more difficult challenges. While outwardly cheerful and optimistic about everything, on the inside the protagonist's hurt stems back as far as her name; in her dream in the first episode she says, "Are you calling me? That name, Shiina... I don't like it. So next time you want to call me, do me a favor and don't use that name." Using heart-thumping music of the same three piano keys to further the idea of death, Shiina asks, "Am I going to be gone from this world?" She fears losing those closest to her, but must endure.
