Fictional character biography
Mikoto is a close friend of Tenma Tsukamoto. She is tall and well-developed, but is also tomboyish. She has a black belt in Kenpo, and is often seen sparring with her childhood friend Haruki Hanai. Mikoto is a good athlete, learning how to swim when she had to, and becoming a competent basketball player in a short amount of time.
Although she is always trying to help out others when she sees them in trouble or having emotional/relationship problems, she is a rather klutz when it comes to facing her own relationship emotions.
According to the last Japanese poll performed by the publishers of the manga, Mikoto is currently the fifth most popular character in the series.
Relationships
Mikoto had a crush on a previous senpai two years her senior, who tutored her in middle school and helped her get into Yagami High School. However, she gave up on him after discovering that he got a girlfriend after he went to college.
Despite Hanai and Mikoto having their own love interests, people around them sometimes think that they are too close to be just friends, as usually Hanai calls Mikoto "Miko-chan" when they are alone. Her friends also tend to tease her claiming that Hanai's her fiancee to be.
Often harassed by Kyosuke Imadori because of her breast size of D or larger.
Mikoto was dating Hiroyoshi Aso until recently, but the two broke up. The reason is a mystery as Asō claims he still likes Mikoto, but had to end their relationship.
Mikoto was the first person to befriend Eri Sawachika at Yagami High, not being intimidated by her wealth and social status. The two friends had a brief falling out because Eri was caught talking about her to Tenma behind her back, but later managed to resolve the conflict while watching a fireworks show.
She and Akira Takano are currently scheming to get Eri confess her feelings to Harima.
