You thought your neighbors were bad...but at least they're not aliens trying to kill you!
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.
Galopoula’s invasion is swiftly brought to an end thanks to an unlikely ally. The Rank Wars continues with Tamakoma-2 going up against B-Rank Katori and Kakizaki squads. Will the new techniques that Tamakoma-2 learned from their mentors be enough to help them win?
