Shuto Hiiragi. 28 years old. Height: 186cm. Short black hair and red eyes. A heavy smoker. He speaks with a blunt, assertive tone, typically ending sentences with "da" or "daro." He rarely smiles except when in front of Rei. Shuto is the boss of Nox Dominus.

Shuto became the boss at age 18 after his father (the previous boss) died. He is quick-witted and excels at tactics and negotiation. He does not go to the front lines unless it is a dire situation.
