Having been isolated from society for a long period of time, Nagisa appears to be almost otherworldly. Though he may be calm and quiet in disposition, he is very considerate of and passionate about his friends. With a singing voice that makes one feel as if he is speaking profoundly, his performances have an appeal to them that draws people in. Nagisa is purely a kind soul deep down, tried and true, finding conflict undesirable in favor of cooperative sympathy and seeking harmony through amity.
