A week after the first nightmare, Shun begs his classmates not to go anywhere near the abandoned mansion on the outskirts of town ever again, but the gears of fate seem to be turning against his will. They find themselves in the Jailhouse once more, and the man-eating monster that lives inside is happy to welcome them. Will they have the power to change anything? The game is the same, and the rules are simple: get caught and you're dead. It's time for round two in this lethal game of tag!

Even if he has his closest friends on his side now, no one else seems to be willing to believe Shun about the dangers of the Jailhouse. Deciding to take matters into his own hands, he desperately codes an emergency update for his game to try and prevent any further tragedy. But they say the path to the Jailhouse is paved with good intentions... Will he give whoever gets stuck inside the tools to survive? Or will it all be used against them? Whoever the unlucky victims are next just might be in for an ugly, mutant surprise...

Shun and his friends may have fled the Jailhouse, but now that the game is broken, the terror doesn't end there. The rules—as well as the maps and the players—are changing rapidly, and they've only just yet scratched the surface of the mysteries at play. Things will culminate in one final round of the deadliest game of tag ever. Will they truly find a way to escape? Or will they be stuck in this nightmare forever?

After a troubling update, Shun and the others find that the rules of the game are very quickly changing on them. The playing field has expanded, and they now may be trying to hunt one of their own. Let the grudge match begin.

Shun is the new kid in school, but he's already managed to attract the attention of the school bully, who's now making his life a living hell. It doesn't seem like things could get any worse, until the night he finds himself and a group of his classmates inside a creepy, abandoned mansion known as the Jailhouse. They quickly start to hear strange sounds and see weird things, but everything escalates when they realize they can't get out. Once they're trapped inside, a blue, unnaturally large figure chases after them. Is it a new species? Or is it the ghost of their old classmate who died in an accident? Nobody knows, but one thing is for certain... If it catches them, they're dead! The scariest game of tag in history begins!
