Aya is a freshman at Toudou Academy. She has a similar build to her sister and is close to equaling her in bust size. Since the first time they met, she has decided to become Souichirou Nagi's wife because she believes it is fate and it follows the tradition of the Natsume women. This attraction to Souichirou also leads to a rift between her and her sister, as Souichirou is in love with Maya. Though out the series, she has increased her skill and dedication so she can support Souichirou in anyway.
