The battle comes to a head, both at home and abroad! As Perrier clashes with Tomie for command of the game, the Queen's elite combat unit bears down on Ryouta's stepfather and Iida, who struggle to maintain their hold on the control room. The players on the island and their rescuers are up against it too, sustaining a barrage from yet another type of drone with unique attacks that yields further losses. And regrouping proves no easy task, especially when Ryouta's greatest rival challenges him to a duel, leaving him with agonizingly few choices...
Limiter's Off! Soga's death crushes Ryouta and frees him from what was subconsciously holding him back. With kindness and humanity left by the wayside, he zeros in on what it will take to most efficiently beat the game. In the process, he faces off against the duo of Kira and Tougou. How will Kira handle having his back to the wall now that he's grown up a little?! The dust settles on the island following the rule change, and a new team is formed! As the veil is lifted on Oda's previously untold backstory, a new arc begins, and a face from Oda's past joins the fray!
By all counts, Ryouta Sakamoto is a loser when he's not holed up in his room, bombing things into oblivion in his favorite online action RPG. But his very own uneventful life is blown to pieces when he's abducted and taken to an uninhabited island, where he soon learns the hard way that he's being pitted against others just like him in a explosives-riddled death match! How could this be happening? Who's putting them up to this? And why!? The name, not to mention the objective, of this very real survival game is eerily familiar to Ryouta, who has mastered its virtual counterpart-BTOOOM! Can Ryouta still come out on top when he's playing for his life!?
A hero's last stand...? Years ago, Tougou lost the entire team under his command in the line of duty. Carrying the weight of their souls on his back, he has tried to make it through the Game with honor while protecting those most vulnerable. Now, back up against the wall, he'll risk it all for a chance at redemption. Only one man is walking away from this battle to the death!
The calm before the storm... It's the beginning of the end as Perrier's troops arrive on the island to rescue the surviving players. Sakamoto and his friends are relieved the killing is finally over...or is it? An unidentified aircraft is approaching the island, carrying the US Army's drone troops. Xaviera is looking for a rematch--will the island become their collective grave after all?!
