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. Taking in a talented new member, the squad begins to train and develop new strategies, but, amid these efforts, the team is shaken by a heated dispute-one that could jeopardize their ticket to the Neighbor's dimension.
Gatlin, Ratarykov and Wen Sou manage to infiltrate HQ, but Border knows their goal thanks to Yuuichi Jin's predictions, and positions the top 4 attackers to protect the away ship.
Kuroe and Kitora, along with Sasamori and Tsuji, form duos to take down the ace Idras, but Yomi deduces how Idaten works to intercept Kuroe's attack, injuring her in the process.
The invasion concludes with Border being able to prevent the invaders from destroying the Away Ship. Kazama defeats Ratarykov, Konami defeats Gatlin with assistance from Tachikawa's torso, and Kou blocks Gatlin's last attempt at destroying the Away Ship.
Youtarou Rindou announces that Hyuse wants to join Tamakoma Second after some discussion Osamu allows him to join however Osamu needs to meet with border's top brass in order to let Hyuse join border.
The Rank Battle season will be cut early so there will be no promotion test for A-ranks but thanks to Chika, B-ranks will be picked so another condition was added, for Tamakoma Second to join they must be B-rank #2 at least on top of that Hyuse must start
