Matsugane Aya

A quiet, spacey-seeming meganekko with a surprisingly intense personality on the inside. She fantasizes a lot about being sex-trained like the characters in the erotic novels she reads, and tends to get excited even if she's on her own.

Her family owns a sex shop, so she's very well accustomed to sex toys. She's given herself a self-imposed challenge of secretly wearing as many lewd things she can while in school.
