Like many of his peers, Ataru Kashiwagi has found himself addicted to the newest social networking service, Real Account. But one day, Ataru and almost 10,000 other people, get sucked into the Real Account Zone, where they have become players in a series of deadly games. The basic rules of these games are simpleāif you lose all your followers, you die in real life, and if you die, all of your followers die with you. As these depraved games decimate the players around him, Ataru must use quick thinking and his knowledge of Real Account to win each round and return to the real world. But when true friendship determines whether he lives or dies, can Ataru really survive when the only people he can count on are his Internet friends?
Social Justice Hunters 24/7 concludes with a decisive battle between Yuma and Zui, but this is soon followed by a fateful reunion between Yuma and Ataru...and why is Ataru trying so desperately to kill his own brother? In the next game, "Anonymous Classroom," the players must root out the hidden traitor amongst them, but with each new attempt ending in failure, another player is sacrificed. There is evil lurking amongst them, and Yuma is beginning to wonder if it might be him!
