固法 美偉

Mii is a recurring character in the Toaru Kagaku no Railgun side story. A high school student of Academy City, she is a Level 3 esper and is Chief of the 177th Branch of Judgment where Uiharu Kazari and Shirai Kuroko work. As their senpai (upperclassman) and chief, she tries to make sure both girls take their work at Judgment seriously and at the same time wants them to be safe. Her ability is very similar to a x-ray vision. Mii displays a responsible and motherly maturity rarely found in girls of her age; an attribute that earned her station of leadership in the 177th Judgement Branch and the universal respect of her juniors, to whom she is a lovingly-kind and reliable big-sister. That said, she is still a teenage girl who shows a warmly mischievous streak when at ease, and can be just as tender-hearted and vulnerable as any 16-year-old girl when it comes to matters of love [From Toaru Majutsu no Index Wiki]
