In 2175, Sol faced Justice directly. During the fight, which Justice won, she discovered that Sol was a Gear. Justice attempted to assert her power as a Commander Gear to control Sol, but was unable to do so. Exploiting her confusion and weakness from the fight, the Holy Order, led by Ky, sealed Justice away, bringing the war to an end. However, a Gear named Testament began a plan to free Justice, and to stop it, the Union of Nations held a tournament. The canon stated that Sol was the winner of the Tournament, which also resulted in Justice discovering that Sol was, in fact, Frederick. Justice, in her dying words, commented that she wished that "... the three of us ..." could talk one last time, and Sol swore to kill Asuka.
