Ashihara, Daisuke

Osamu has less than sixteen minutes to safely deliver Chika, who's been cubified, to HQ, but he may not make it in time.

As the Neighbor invasion continues, Osamu's brave defense of Chika lands him in combat against the Neighbor commander.

Border is abuzz with gossip about Tamakoma's new recruits, Osamu and Yuma, who attract so much attention that top A-rank agents challenge them to duels.

With only seven seconds left until the crossroads, Black Triggers face off as Miwa activates Fujin to bring the invasion to an end.

"Osamu successfully convinces Border HQ to allow Hyuse on to their squad, and now the moody neighbor from Aftokrator must make his way up through the C-Rank Wars to officially become part of the team. Meanwhile, Tamakoma-2 gears up for another B-Rank Wars match against the analytical Oji Squad and the unconventional Ikoma Squad. How will Tamakoma-2 handle a squad that operates almost exactly like they do and another squad that doesn't even seem to care that there's a match going on?!"--Back cover.

"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?!"--Back cover.

"Galopoula's invasion is swiftly brought to an end thanks to an unlikely ally. The Rank Wars continues with Tamakoma-2 going up against B-Rank Katori and Kakizaki squads. Will the new techniques that Tamakoma-2 learned from their mentors be enough to help them win?"--Back cover.

"Another invasion is underway, and alien country Galopoula plans to infiltrate Border HQ. The A-Rank and B-Rank agents have their hands full on the ground, but the commotion outside is only a distraction! A handful of humanoid Neighbors manage to sneak their way into Border's away ship hangar, and it's up to the top four Attackers to stop them!"--Back cover.

Having fought their way into the top 8-Rank group, Tamakoma-2 gets to battle for a chance to make A-Rank.

Trion soldiers swarm Mikado City, wreaking havoc and capturing isolated Border agents, so when the sinister humanoid Neighbors orchestrating the attack target Chika for her massive Trion, Osamu may be the only one who can save her.
