Fei has pastel green hair that seems to be tied into two high ponytails on each side of his head (which resembles bunny ears) and pastel green eyes (which are a tad bit darker than his hair) that strongly compliment his pale skin tone. He is considerably tall. He is shown to always be a cheerful person who helps anyone in need. He also states that there are still people from the future who like to play soccer just like him. Even with his cheerful and caring personality, he can be serious at time
