Miu is the Wing of Messiah. It is unknown which of the four saints resides within her. She is to lead the Messiah to the right places. Miu does not have any magical power or physical talents, but she has an intelligent mind and invents many odd inventions. One of her inventions is a vacuum that sucks all the elements from the nearby air, making all magical power useless in the area. She is shunned at a young age by her family, who are renowned for their magic prowess. She is abused by the villagers, until a kind inventor took her in. That is where her inventive mind presumably came from. When the inventor died from an illness, she was abused by the villagers again, until Hime came and protected her from the villagers. After that Miu is shown to always follow Hime around. It is implied that she has some feelings toward Shinya.
