Destroy thy Neighbor! A gate to another dimension has burst open, and invincible monsters called Neighbors invade Earth. Osamu Mikumo may not be the best among the elite warriors who co-opt other-dimensional technology to fight back, but along with his Neighbor friend Yuma, he'll do whatever it takes to defend life on Earth as we know it. Having defeated Arafune and Suwa squads in the Rank Wars, Tamakoma-2 settles nicely into the middle B-Rank group. Their next match is against the infamous Suzunari-1 and the all-female Nasu Squad, both of which have their own ace Attackers! Can Tamakoma-2 overcome this challenge and fight its way into the top group without getting washed away by the tide?
