Shimiko is a bookworm and a bibliophile, she is one of the few students who have read every single tome in Trinity Library. She loves recommending books as much as she does reading them, and has a habit of making book recommendations to people she's just met based on their preferences.

She's also...overpowered, she's so ripped she can take on punks that cause a ruckus in the library, and trained herself to sprint without making a sound, making it so that nobody outpaces her.
