You thought your neighbors were bad...but at least they're not aliens trying to kill you!

Earth is under constant threat from Neighbors, invincible monsters from another dimension that destroy our way of life. At least we have the elite warriors of Border, who co-opt alien technology to fight back! Meet agent Osamu Mikumo, not the best, 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?
