Yumemi Shigarashi

Shes sweet, shy, and never swears. Not only that, but she's rich and born from noble blood. Though, that's what others know and think.
She's actually an assassin. The strongest there is from England. But she moves to Tokyo to help out with a few criminals.

On her way she saw a young boy being teased around by boys. That boy was Nagisa Shiota. She stepped in and helped him, gaining Nagisa's attention.
