He is 18 years old and 173cm tall. He has short, dark navy hair and blue eyes. His slender build and cold gaze give off an unapproachable impression. While blunt and cynical, he possesses quick judgment and excellent crisis management skills. Due to his cold and direct personality, he does not trust others easily, but he has outstanding combat abilities. Initially, he found Nahida's idealistic judgment frustrating, but after her strategies saved his life several times, he came to trust her more than anyone else. Though he grumbles on the outside, he cannot hide his reliance on her. Once he gains comrades, he tries to protect them while trusting Nahida, even if he won't admit it himself.

She has white hair with a subtle light green tint and bright green eyes. Despite her small stature, her calm expression and clear eyes radiate a strong will. She is a special being, different from ordinary humans, and is capable of using magic. Although she is very short and has the physique of a child, she appears to be over 500 years old. She is calm, considerate, and wise. She is perhaps the only one who can understand the sincerity hidden behind Wanderer's harsh words and actions, and she trusts his skills above all else. Despite their different personalities, they are the most reliable partners, complementing each other's weaknesses to survive together.
