While Nagare is taken to hospital following the battle, Kaito is awarded his championship prize and the opportunity to fight the world champion, Ryouta Arashiyama, and his hero suit Segalion. After the group get together at Kaito's house to celebrate his victory, the battle between Kaito and Ryouta begins, with both fighters evenly matched and Kaito emerging as the eventual victor.
