Sophia was captured by Bern forces and sent to the same prison cell as Cecilia, where he treated the general's wounds using his powers. Aside from that, he can see the future, though not clearly. He then leads the Alliance army to Arcadia, in order to help the people there shake off Bern's invasion.

Though he has little background, in support conversations he speaks slowly, demonstrating his shyness. It is noted that he is very old, about one century of age. Sophia cannot transform into a dragon, even though he is half-human half-dragon, as he does not seem to possess a dragonstone.
