Freya shares exactly the same appearance as Chi since they are twin sisters. She has the same hairlock like Chi has. Unlike her sister, Freya wears darker clothes, contrasting with Chi, who has more of an affinity to light clothes. She mostly appears wearing a black PVC outfit and a matching headdress. Her personality is darker, more distant, and cold-looking, unlike her innocent and warm-looking sister. Like Chi (Elda), Freya is one of the legendary custom-made Chobits.
