Clash! Yūma vs. Midorikawa

Short Summary
''The battle between Yūma and Shun begins, with Shun getting the upper hand in the first two rounds, surprising Osamu and Yōtarō, the latter who gets angered at this. Yoneya explains that it's about the difference in experience, and Yōtarō says that shouldn't matter, but Yōsuke says that's not what he means. After losing the first two rounds, Yūma then gets the upper hand, defeating Shun in all subsequent rounds. In the last round, Shun decides to battle Yūma head on, again losing. After the battle, Shun apologizes Osamu in front of so many people, as it was proposital, but Osamu takes the chance to explain that he actually lost to Kazama 20 rounds and only got a draw in one round. Jin then comes to call Osamu and Yūma to a meeting, with Shun greeting him. Jin, Osamu and Yūma then go to the meeting room, accompanied by Yōtarō mounted in Raijinmaru. There, Border's leaders explain about the upcoming invasion and enlist Yūma's help in identifying the attacking country and preparing for the invasion. Yūma introduces them to Replica, who offers to give them the information they want if they promise to protect Yūma. Kido accepts his offer, and Replica begins his explaination.''
