Saya is Ayato's childhood friend. She moved abroad six years ago due to her father's career. She seems to be an air-headed stoic who has trouble waking up in the morning and is directionally-challenged. She uses a 38th generation Lux grenade launcher Helnekrom but later switches to a type 41 Gleaming Form - twin particle guns Waidenholt and Type 34 wave Motion heavy artillery Ark Van Ders for the Phoenix. Like Kirin, she enters the Phoenix for her father's sake.
