Yuri Lowenthal voices friggin' everybody in anime and videogames.
He may get tired if he voices 3+ characters in the Persona 3 movie if it comes out in English. Still, I guess it's not like the male MC to talk much anyways.
Male protagonist is always quiet and nonchalant (even in the manga), Pharos only appears on occasion, and Ryoji doesen't show up till the last half of the story. Lowenthal probably won't even have to talk as much as he did voicing Yosuke.
