Kagari is the titular protagonist of Ikaruga and an ace pilot of both a Butsutekkai unit and a Hitekkai aircraft stored within it known as the Ginkei. Alongside her fellow pilot Shinra, the two would battle the empire known as the Horai in order to find their own freedom.
Kagari has fair tan skin, and brown hair held in a bun with two large hair pins. Her attire consists of a gothic aesthetic, with a black corset, fishnet sleeves and leggings, black gloves and black thigh highs with heels.
Trained as an ace pilot and Mercenary for Horai, she is honor bound to her own personal ideals and beliefs, willing to sacrifice herself rather than dishonoring her commitment. She shows a keen interest in the idea of freedom, and willing to hear out those with varying opinions, as well as working alongside those she had once considered an enemy.
