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. The B-Rank Wars continue, and Tamakoma-2 is up against both new and old foes this time around. With the realization that Chika can, in fact, shoot people, it's anyone's game! But first, Osamu and Yuma need to gather information on Yuba Squad--a squad they've never faced before. Will this new realization about Chika and the addition of Hyuse be enough to take down this unknown foe?!
