Gil is a kind and loyal boy. He is always willing to help out a family member, friend, or soldier, and asks nothing in return. On the battlefield, however, he can be a cold and calculating genius; never attacking without taking a moment to analyze the opponent's statistics. He also has a very unique ability. Gil was born covered from his toes to his neck in bandages. He uses these bandages to mummify an enemy, drain their energy so low they fall into a light coma, and also partially copy their abilities for a short amount of time.
Gilgamesh is a medium height boy, who always wears loose fitting clothing. He also keeps his hair cut so that only one of his eyes is showing, for an unknown reason. The eye the is visible is purple, and he has light blond hair. His entire body from his toes to the middle of his neck is covered in bandaged that he was born with, and he uses as his major weapon.
As a side effect of his battle "form", Gil's hair darkens and his strength drastically increases, which is the exact opposite of what his sister has happen. He also takes off his external shirt, to reveal a loose fitting shirt with no sleeves.
"Sometimes it is better to stay silent and wait, just to see what the others can do. Then you use their abilities to your advantage, making them pick each other off, and then you go in for the winning strike against the one who just so happens to be left."
