She and her guild led an attack against another guild «Silver Flags», leaving only the leader alive. The leader of Silver Flags begs Kirito to send her to the «Black Iron Castle» dungeon, to which Kirito accepts. A few days later, Rosalia tails Silica who is on a quest to get the «Pneuma Flower», waiting for an opportunity to ambush her and steal the precious flower. Kirito sees through the surprise attack, and Rosalia orders her men to attack the Black Swordsman. However, the attempt to murder Kirito fails, and he sends her guild into the dungeon. Rosalia tries to persuade Kirito to form a party with her, but he ignores her pleas and sends her headfirst into the dungeon.
