She has short dark blue-purple hair and green eyes.
She is always focused on her mission and works hard as a WOTA member. She often scolds or lectures Mamoru when he is late or not focusing on the task at hand. She is also a fan of Yuka Ichijo. She knows that he is a fan of Suzuko, but also suspects or knows that he loves Yuka as well, possibly even more than Suzuko. This is because she teased him about whether or no he was just rooting for Suzuko when he was trying to get the TV to work so they can watch the General Elections.
- She the only know girl on the Wota member.
