Ryouko Uchida

Ryouko Uchida (内田涼子) is a 27 year old quantum researcher for the Magic Circle Project. Initially, her research involves a lot of chasing after quickly-disappearing phenomena and seems fruitless, but after she and Kyouji meet the Dragon Cavalry, she discovers that the Magic Circle Project, if successfully activated, would annihilate all of existence; she is then determined to stop it at all costs.
