Io Euclase イオ・ユークレース

A young lass who loathes being treated like a child, Io encounters and eventually joins Gran while in search of her master, who vanished in the Valtz Duchy. Io is persistent and refuses to give up in the face of adversity, but she's a little inflexible, too. As you might guess from the way she bristles at being treated like a child, she can't wait until she's all grown up.
