The youngest of the Element users with a shy personality. Her Element ability Optical Fluoroscopy (光学透化 Kōgaku Tōka) turns her invisible which make her transparent to light, which can extend to Aquarion itself for brief moments at a time, but typically involves her turning herself invisible, while her toy frog-like cat doll remains visible. As a result, when she moves, it tends to seem as the doll is being levitated, leading her classmates to believe that the doll is alive, until she piloted a Vector to form Aquarion. After her identity is revealed to Amata and the others, she starts hanging out with them and showing herself but still turns invisible when shy.
