Having descended onto Underworld, the first group of American players began indiscriminately assaulting any Underworlders they encountered, starting from the nearby Dark Knights and Pugilists. Disgusted by the sight of the American players slaughtering the locals indiscriminately, Asuna invoked the powers of the Stacia super account to alter the landscape, creating a wall of rocks to separate the Dark Territory Army from the American players.
Although modifying the terrain came at the cost of suffering a debilitating headache, Asuna attempted to invoke her powers a second time, only to be stopped by Alice. When the golden knight urged her not to overexert herself, Asuna warned the group that the red knights were people who had come from her world. However, this revelation did not discourage the Integrity Knights, who had the confidence to handle a disorganised and unskilled army despite their great numbers. Hence, Bercouli organised the Human Guardian Army's decoy unit into a phalanx formation to engage the new enemy.
