Cusack

Cusack is a muscular man with long pink hair that almost completely covers his right eye and is tied back in a ponytail. He has a long mustache that reaches his chest and a small goatee. His black mark consists of two black arrows extending below his left eye and a dark patch on his right shoulder that extends beyond his arm.

Cusack is very confident in his abilities. He is reserved and calm, yet when it comes to leading, he knows what decisions to make. He is strict, but at the same time, he can be kind to a certain extent. Once he trusts you, he will never want to hurt you again. He is very attached to his student, Zeldris, expressing the utmost trust and loyalty to the Demon King's third son. Cusack does show some criticism of the Demon King, even going so far as to say that the Demon King is too compassionate towards Meliodas despite his betrayal of the clan.

His outfit consists of a white, sleeveless vest with a high collar and six buttons (the last one undone), black trousers, and knee-high boots. He also wears a pair of long leg warmers, open at the ends, with a black zigzag design down the front.

Cusack is able to connect with another individual by making eye contact. When activated, Cusack's and the victim's eyes glow with the same color, and the target will mimic Cusack's movements. He is also highly skilled with swords, being a formidable dual swordsman.
