Constellation:

Character:

The female lead of the show and a Flame Haze. Initially she is concentrated solely on her duty as a Flame Haze, going as far as to not bearing even a name. She sees Yuji only as a Torch, an object, marginally interesting because of his status as a Mystes. However, she slowly opens up to Yuji, coming to think of him as a person, despite being a Torch, and eventually comes to love him.
