At the Border Defense Agency's headquarters, the B-Rank Wars are underway as each team fights intensely to secure a spot in the upcoming Away Mission. Though Osamu Mikumo and the rest of Tamakoma-2 have pulled through thus far, the final rounds will require them to push far beyond the limits of their current abilities.
