Kyosuke Kagami

Kyosuke is a student at Taiyo High who volunteers to help Batsu find his mother. It is later revealed that Kyosuke is behind the kidnapping and was working for his twin brother, Hyo. Ultimately, Kyosuke changes allegiances, and helps Batsu and Hinata in defeating Hyo, while convincing Hyo that force was not the way to achieve their dreams.

In Project Justice, Kyosuke becomes concerned when he meets Kurow Kirishima and sense the power helping him. When Hyo is later possessed by the spirit of the brothers' father, Kyosuke reluctantly fight his brother again. After the apparent death of Hyo, Kyosuke disappears, with his friends at Taiyo High waiting for him to return to school. Whether he got out of the burning Justice High School HQ remains unknown.
