As the game progresses, Robin begins to slowly subconsciously unlock his own hidden powers as one of the Solfords. The party learns of the lineage of the Solford family and their terrifying powers and their struggle against the Dark Ones. When they finally find Patricia, to Robin's horror, her mind and body are corrupted and twisted into evil by Dr. Killbait who encased her in a suit of high technology powered armor. As Robin attacks Killbait out of rage, Patricia intervenes and easily fends off Robin with a forceful blast of energy. Robin and Patricia duel each other in a terrific magic battle with Robin being able to easily shield his friends from her attacks using his powers. In the midst of the attack Patricia comes to her senses and stops her attack at the extreme protest of Killbait. Unable to detach herself from the armor as it is directly connected to her body, she begs Robin to stop Killbait and to erase the darkness from the world as she slowly ascends and sacrifices herself by causing her armor to self-destruct. Upon seeing the death of his adoptive sister and closest friend, Robin loses control of himself and is about to charge and attack Killbait when he is stopped at the pleading of Julia. Robin then swears an oath of vengeance against Killbait just as he is making his escape.
