Nate Mitotsudaira is a knight of Hexagone Francaise and successor of the Mitotsudaira Clan. Half-human, half-wolf. Although she cannot transform into a wolf form, she possesses the form’s great strength. She uses her special weapon, her silver chains, to great effect.
Because of her chivalrous nature and strong sense of duty, Nate feels very protective of the land on the Musashi, which technically falls within her family's domain.
