Osamu Mikumo vs. Sōya Kazama (Episode)

Short Summary
''Despite knowing he doesn't stand a chance, Osamu decides to accept Sōya Kazama's challenge. After defeating Osamu multiple times, Kazama tells him that Jin gave Fūjin away so that Yūma could join Border. Hearing this, Osamu asks for one more round, this time managing to get a draw. After the battle, Yūma greets Osamu, and he has a short discussion with Kyōsuke Karasuma and Ai Kitora. Osamu and Yūma are then called to the Sniper's training area, where they find out Chika destroyed the wall. Rumors start to spread about the three newcomers, and Jin, told about that, says he already expected that.''
