"Destroy thy Neighbor! 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. Our hero Osamu Mikumo may not be the best agent, but along with his Neighbor friend Yuma, he'll 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!"--Provided by publisher.
