World Trigger Volume 19

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, hell do whatever it takes to defend life on Earth as we know it.

With the final matches of the B-Rank Wars looming over Tamakoma-2 and the other B-Rank Squads, all the agents are practicing and doing their best. While everyone is hashing out new strategies, Ema from Kageura Squad considers throwing his next match against Tamakoma-2 to help Chika stay with her friends on the away mission. But Arafune reminds him that Ema also has the power to protect Chika on the away team!
