She was Index's first real friend after arriving in Academy City. She's pretty gentle by nature, though on the shy side. Not a ton is known about her background—Aisa mentions she was an overachiever at Kirigaoka Academy for Girls, which tracks with what fans can piece together. Her ability is Counter Stop, and while her exact level hasn't been officially stated, she apparently ranked among the top psychics at her school, suggesting she's probably pretty powerful.
