Amelia Wil Tesla Saillune (アメリア・ウィル・テスラ・セイルーン)

Amelia is Lina's best friend and a female magician and the princess of the kingdom of Saillune. She is a fighter of justice and her only desire is to fight and defeat evil.

She is a bit naive and clumsy, and has a faible for holding weird and dramatical speeches before fighting an enemy.

Philionel El Di Saillune, the crown prince of Saillune, is Amelia's father. When she was very young, her mother was slaughtered by an assassin, Booley, and as a result, her older sister, Gracia Ul Naga Saillune, left Saillune to learn offensive spells and the ways of the world outside royal boundaries.
