Mikoto Kirishima

Mikoto attended the same elementary school as Taiyou when they were kids. They were in the same class and had a real friendly relationship. Unbeknownst to Taiyou was the fact that she harbored a huge crush on him. She is first cousins with Tenma Kirishima. Mikoto comes from a prestigious family and is considered to be very well mannered, socially adept and an all-around perfect girl. She can be quite scary when picking apart suspicious problems to the point where Tenma is terrified of her.
