Shiina Tamai

Shiina Tamai (玉依 秕 / 玉依 シイナ Tamai Shiina) is 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.

As the second half of the manga begins and at the end of the anime, Shiina works hard and obtains a scholarship to the prestigious Banda Academy Junior High. In the manga she then moves in with Takeo and Norio after her father's aircraft was attacked by dragons a second time. In an attempt to save Takeo and herself from a United States military attack on a nearby escaped dragon, a missile cuts Shiina's body in half. The following nuclear explosion completely destroys her body. Soon after, she is reborn off the shore of her grandparents' island and it is revealed that her (and Mamiko Kuri's) dragons are, in fact, the whole world. The daughter of Shiina and Takeo (conceived when Shiina has sex with Takeo after declaring her love for him, before the destruction of the world) becomes the new Eve when Mamiko destroys and recreates the planet.

Shiina and her friends usually write her given name with katakana (sometimes as シイナ and sometimes as シーナ); Shiina's mother, Misono, prefers the kanji rendering of her given name (秕), which means "a seed that cannot germinate" or "an empty husk." Shiina's given name is romanized as Shiina in English-language versions and the Japanese graphic novels, while Kodanclub romanizes her given name as Shina.

Her Japanese voice actress is Asami Sanada. Her English voice actor is Kelly Ray.
