"Border headquarters is abuzz with gossip about talented new rookies Yuma and Chika. But it's Osamu who attracts the most attention when an A-Rank agent challenges him to a duel. Then it's Yuma's turn to fight when another A-Rank agent challenges him! Plus there's that meeting with Border's top brass that they just got called to ... Is there such a thing as too grand an introduction?"--

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. Osamu has less than sixteen minutes to safely deliver Chika, who's been cubified, to HQ. Will Osamu make it in...

"After the recent Neighbor invasion, thirty-two agents went missing and Osamu, Yuma and Chika, a.k.a. Tamakoma-2 Squad, intend to go get those people back. But first they need to rank up through the Rank Wars. Having won their first match, they must now prepare to face off against Arafune and Suwa squads in the middle B-Rank Wars" -- provided by publisher.

The Rank Wars match against Kakizaki Squad and Katori Squad continues, and Tamakoma-2 isn't pulling any punches. The other two squads seemingly don't stand a chance against Osamu and Yuma's new combination technique! Could this be the push Tamakoma-2 needs to sweep the competition? And what's this about a new squad member joining them?!

"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...
