A price too great... On an island where people are forced to fight each other to the death using explosives, Ryouta places his bets on escape via a hijacked helicopter. But what happens when his plan goes abruptly awry?! As his allies drop left and right in a hail of bullets and as an unexpected ally lends him a hand, Ryouta becomes mired in the fiercest battle he has yet experienced on the island. When the veil concealing the true intent behind "BTOOOM!" is ripped away, will the precarious war Ryouta has been waging on the live-action death match's sponsors finally come to a head?!

In a hell called the Sanctuary... When his plan to escape the island ends in failure, Ryouta drags his battered body ashore, only to be approached by a mysterious girl who leads him to a community of seven combatants managing to peacefully co-exist. With Ryouta's arrival, though, the balance is shattered as the eight chips needed to win a ticket back to civilization are suddenly within reach! It doesn't take long before the first death is discovered, and so a brand-new arc commences with an explosive tropical murder mystery!!

In this "bad ending" conclusion to the story, Ryouta casts aside his history with Oda and, with it, his hesitation, as he squares off against his former friend and rival, who has taken Kaguya and Uesugi hostage. Meanwhile, Himiko and Kira hatch a plan to save their captured allies. But Ryouta's decision will have dire consequences for everyone involved, and even he might not emerge from this final battle unscathed...Who will be left standing as the curtain falls on this explosive drama?!

The equilibrium on the island has been greatly thrown off by Takanohashi's sudden announcement. There's only one day to go before the game is up, and only three people left who can beat it...leaving the players bewildered by this sudden rule change. But that bewilderment turns into anger and leads to suspicion, causing the bonds between players start to fray. And when Himiko is wandering around the island, looking for Ryouta, another stray catches sight of her...Will Himiko ever be reunited with Ryouta?! Meanwhile, Ryouta himself is assaulted by a tragedy born out of suspicion!!

The Sanctuary arc comes to an end!! While lying unconscious on a beach, Ryouta is approached by a mysterious little girl, Kaguya, who later leads him to the Sanctuary, where seven "BTOOOM!" players have been eking out a peaceful coexistence. But Ryouta's arrival means there are enough chips to send one player home, and a string of ghastly murders follows!! The killer cuts down player after player, and Ryouta soon discovers that he has fallen into the villain's clutches, only to escape by the skin of his teeth! As the curtain falls on the battle of wits between Ryouta and the murderer, another rises on the most ferocious fight the Sanctuary has ever witnessed!!

A forbidden partnership forms?! "BTOOOM!" and its trademark bombs have decimated both the island playing field and players alike, but is the final stage of this live death-game now in sight?! Tsuneaki Iida, programmer for Tyrannos Japan, shares key information about the game's masterminds and the conspiracy, and he lets Ryouta in on a secret function hidden in the BIMs, asking him to take down the game's system. Still plagued with doubt, Ryouta steels himself for battle and carries out his do-or-die plan to hijack the Tyrannos Japan helicopter. There's no turning back now!! But the price Ryouta will pay for his operation is heavy...and an unexpected turn of events awaits!!

A mysterious killer has left a trail of dead swordsmen in their wake, and the grisly corpses hint at a fiend possessed. A chance to confront the culprit presents itself, but Kuroko finds herself in unfamiliar territory-when, for the first time, an opponent completely outclasses her in combat! In order to win (or even survive) against this unparalleled swordsman, Kuroko's going to need an ace up her sleeve, and her answer is...movie magic?!

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...

What happens when you cross the ultimate line?!Men and women, old and young, have been forced onto an island in the middle of nowhere and into a murderous game using small bombs called BIMs. Now accustomed to the gameplay of real-life "BTOOOM!", expert player Ryouta Sakamoto coolly and calmly disposes of opponents and giant lizards alike as he protects his allies and their rations. But in the lawless microcosm of the island, is it really such a smart idea to play by the rules? When a mysterious player confronts Ryouta with not a handful of bombs but the cruel blade of a knife, will he be able to think outside the video game box long enough to find a way to survive?!!
