Siegrune

ジークルーネ

Siegrune, more commonly known as Rune, is a strong-willed warrior of the Wolf Clan. This background gives her certain personality traits that can come across as somewhat stubborn in some situations, but she is also extremely loyal and protective of those she cares about.
She has silver hair and red eyes, and a slender but toned physique, which is the result of her many hours of hard work training her body for battle. She often carries her weapon and wears clothes that are fitting for the people in Yggdrasil.
She is especially protective of her sworn father, Yuuto Suou. She did not approve of him at first because he was physically weaker than most Wolf Clan warriors, but as time goes on and she sees his battle prowess alongside his kind, well-mannered way of living, she begins to develop feelings for him.
She is also one of the Einherjars, a group of magic-wielding warriors. They possess runes that give them certain superhuman abilities, varying from enhanced physical strength to actual magic. She fights with a katana that was a gift from Yuuto.
