Nishi no Yoki Majo: Astraea Testament

Firiel wears her mother's necklace to a royal ball expecting a brief escape from her quiet life. Instead, the pendant identifies her as a missing member of the royal family and places her among the candidates for the throne.

Her newly discovered heritage makes her valuable to people with ambitions of their own. Questions about her father's research and her family's past bring danger rather than reassurance, drawing her childhood companion Roux into the struggle as well. Firiel must learn whom to trust without allowing court politics to decide what kind of future she should want.
