Aya has long plum-colored hair tied back in two ponytails by two green bows and matching colored eyes.
Once had a cold attitude when she first started out as an idol.
Nickname is "Ah". As the younger sister character is said to be a Lori frame, she has a small and young atmosphere for her age. As if she applied for herself and became an idol, she had a strong desire to climb, and she was trying to become a center. The position was lowered so that the twin tails would not be worn over. There are only hard-workers and dance skills are high. She was worried about her low popularity, and she had a cold attitude for a while. She worked part-time at a maid cafe and threatened Eri Kumasa who visited the store during the popular voting period. My hobby is watching anime. My favorite food is Ooba. Good friendship with Yuuka. 
- She is 18 years old.
