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.

With less than 16 minutes left until the crossroads Jin predicted, the endgame looms. Will Osamu make it back to HQ in time to save the cubified Chika?
