The "official" DearS exchange student to Takeya's high school, and Ren's main rival. She was seen as a "fake" upon arrival, due to an enrollment mix-up with Ren entering the school. Eventually, she took it upon herself to train Ren to become a better Dears. This tutoring has the unpredicted side-effect of her seemingly developing feelings for Takeya. She initially mistakes this as the "Gift", though she later realizes that she was experiencing love. Miu has a bit of a tragic past when she was younger, when her former master was brutally murdered and she was unable to do anything to save him, despite her best efforts.
