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!!

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 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 genius player hardens his resolve!! "BTOOOM!"--the death game that forces real people to kill each other with explosives--charges into its final stage! Ryouta unexpectedly runs into his former senpai Tsuneaki Iida, now one of the Tyrannos Japan masterminds supervising the deadly contest on the island. Iida reveals the true nature of the bomb game and proposes a surprising plan to Ryouta!! Then the few remaining players instigate a final battle to secure their escape. Will Tougou and Sakamoto, both planning to get off the island in a team of four, end up in a three-way fight to the death with Oda?!

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!!

One wrong move, and it's all over!! The death game "BTOOOM!" charges headlong into the final phase!! Ryouta survives a fierce battle against his sworn ally, Kiyoshi Taira, but the scars left on his heart run deep. Meanwhile, Kousuke Kira, hungry for a rematch with Ryouta, wanders the island looking to get back into the game. But when he's cornered by a mysterious group with unfamiliar BIMs and a merciless team strategy, the devious junior high schooler will have to think fast if he wants to live long enough to settle the score with world ranker SAKAMOTO...!!

A new menace looms... Sacrificing his humanity for a better chance at victory, Oda moves forward, leaving Okita and the past behind. As the stage once again returns to the final day of the game, a new weapon is deployed--one that will bring either salvation or certain destruction to the remaining players. But the island isn't the only battlefield! With things heating up back in Japan, the implications of the unfolding events at home could be monumental for all involved...
