World Trigger. Vol. 18

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.

Osamu successfully convinces Border HQ to allow Hyuse to join their squad, and now the moody Neighbor from Aftokrator must make his way up through the C-Rank Wars to officially become part of the team. Meanwhile, Tamakoma-2 gears up for another B-Rank Wars match against the analytical Oji Squad and the unconventional Ikoma Squad. How will Tamakoma-2 handle a squad that operates almost exactly like they do and another squad that doesn't even seem to care that there's a match going on?!
