Amelia Wil Tesla Seyruun ( アメリア・ウィル・テスラ・セイルーン Ameria Wiru Tesura Seirūn) is a young miko and the princess of Seyruun with an unwavering, quixotic belief in justice. She joins Lina's group during the first TV series. Amelia longs to be a "hero of justice" and quixotically pursues her quest by following Lina and fighting (what appears to her as) villains. Amelia's naive tendency to believe whatever she is told sometimes leads her to mistake friend and foe. In the novels, Amelia is the same age as Lina, but in the anime and manga franchise, Amelia is a year younger than Lina and smaller (though very busty, much to Lina's annoyance). In all incarnations of the franchise, Amelia's manner is that of a little girl playing a crusader.
