Chang Gai Steiner

Оригінальне ім’я: 張･剴･シュタイナー

17 years old, and a second-year student at Seisho Academy. Lu’s twin brother. An excellent student, and athletic as well. He dislikes Daisuke for the childish way he’s acting now that his dream of being a hero is coming true. But in fact, just like Daisuke he remembers the prophecy Milo gave him: “Doubt everything.” He has the capability to be a cool and collected leader, a talent he puts to good use in the S.D.S. (Shibuya Defense Service).
