Rumi Shimada is Akio Asakura's teacher. She first appeared in Wangan Midnight volume 1, chapter 4.
To understand why Akio loves to drive, Rumi decided to sit in the Devil Z. Later she admitted that Akio is a talented driver, despite the fact that many people called the S30Z a devil. But Akio later spoke something that made Rumi think that Akio is flattering her.
In later stories, Rumi will sometimes sit with Akio or Reina. This further made her understand Akio.
