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.
The sealed environment test heats up as squads go head-to-head in a variety of tests. From group assignments to tense battle simulations, everyone is giving it their all. Meanwhile, at headquarters, the top brass keep a careful eye on everyone’s achievements to see who stands out. One thing’s for sure—it’s going to be an intense competition to see who makes the final cut for the away mission!
