Themis (テミス) is the leader of the clan Trinity.
Themis has extremely long hair that she has tied into two ponytails, with some strands on the sides of her head. She wears a dress that reveals her shoulders and cleavage, a large necklace, and armbands.
Themis is manipulative and tries to scheme against her opponents, such as having Kanehira Hideaki try to kill Sudou Kaname during the Hunting Game, and later planned on using her sigil on the latter to attempt to win against his clan. However, her plans usually backfire, as she lost the bet to Sunset Ravens and her sigil plan was prevented by Mokuren and Towa's future sight.
