Grace Steward グレイス・メイトランド・スチュワード

During her active service as a witch, she participated in many battles, including Dunkirk's retreat and the Battle of Britain, as a part of the Liberion Volunteer Army. After she retired as a witch, she started working on unfamiliar desk work, but based on the belief that songs will save people, she set up a concept of "Aviation Witches Music Squadron" that gathers witches who cannot participate in battles for various reasons. She rushed to get budget and recruit witches.
