Aya is just a small, delicate, girly anthro moth.

Her small stature and inerrant squishiness due to being an insect can make her terribly shy when interacting with larger beings but she's relatively friendly.
(Though not always terribly interesting to talk to due to being incredibly enamoured with frilly lacy dresses, pretty flowers and fluffy critters much smaller than herself.)

She's fairly capable of being quite clever when the mood strikes her but getting her to set her mind to something can be a chore at the best of times.
