Osamu Mikumo 13

Short Summary
Yūma fights Kageura and Ninomiya but is taken down. With Mikumo Unit's substantial inferiority to the top-tier B-Class teams, Osamu asks Jin to join them.

Long Summary
Yūma and Kageura begin their battle but it is quickly interrupted by Ninomiya's Hound. Yūma charges at Ninomiya to take him down but Ninomiya shoots Yūma and damages him severely. Yūma attempts a long Scorpion but ultimately fails and Bails Out. Losing the bet, Jin offers to do any one thing for Hus, which includes returning his Trigger. The battle goes on with each party keeping their distance. All the teams decide that not making a move is in their best interests, so they wait until time's up, giving Ninomiya Unit the victory. With this, Mikumo Unit goes down to #8. Commenting on the battle, Kazama points out that while the aces got the points, the non-aces were the important factor. When asked whether Osamu's defeat led to Mikumo Unit's loss, Kazama states that learning through defeat was the way Rank Battles worked, but that Osamu should have depended on something more reliable than his growth. Reflecting on Kazama's words, Osamu asks Jin to join Mikumo Unit.
