|Base of Operations||Naraka High School|
Aya keeps her hair tied up into two pigtails that are held in place by heart-shaped clips. She wears the standard Naraka High School uniform.
Aya maintains an upbeat nature despite having to go through various Eclipses. She is caring of her roommate and is encouraging and protective of her. It is thanks to her that Shie gains the courage to use her ability to fight the Water eclipse.
Aya fights by summoning a flute. When she blows on the flute, sound waves are produced that can destroy oncoming projectiles.
