In "" (2007), Sol Badguy took in a young man named Sin as his apprentice, and traveled the world with him as bounty hunters. During their journey, he met Izuna, who told him that a man called Vizel was seeking out and destroying Gears, by order of Valentine, and that his next target was the kingdom of Illyria. Sol, Sin, and Izuna go to Illyria and find Ky Kiske trapped with a binding spell. With Dr. Paradigm's help they were able to release him. Eventually, they captured Valentine, who transformed herself into a monster. Sol fought her, and after the fight, he found himself in a white space, unable to return. However, he was confronted by That Man, who confirmed that Valentine was a copy of Aria, Sol's former lover. Sol was returned to the real world, where he reunited with his allies.
