The personal guard of Ariadne, and one of the kingdom's most powerful swordfighters. She is very commited to her duty of protecting the princess, and will often stop her from doing things that wouldn't be proper for a princess to do (like fighting or talking to mercenaries). However, her strict nature has made her an excellent guard, but not much of a friend. Helena also doesn't care for her appearance, and even wears chest bandages to make herself look more like a boy.
Her skills are so great than even Mikaeal is wary of her.
