Ruthis is normally considered the usual Shonen Protagonist: Naive, Ignorant, yet Strong. However, there's a way to completely break him, something Pamuros did to him in order to reduce the number of threats: The murder of Ruthis's dear friends, including the one he grew up with, Reis. Due to this incident, he became more cold and distant, unlike himself prior when he was outgoing and helpful. He now adventures alone, shutting people away, still in denial that his friends are truly gone. But deep down, he knows that he can't bring them back.

Ruthis's voice is a little odd, and is one that I don't know if I can describe. Overall, I'd like somebody who's able to sound upbeat and happy, but also depressed and serious.
