In Psycho-Pass (season 1), Sakurai Takahiro voiced Makishima Shougo. In Psycho-Pass 2, he voices Hinakawa Shou. I find it strange that the same voice actor would be cast to voice two different important characters in the same show.
Sure, it's common for a voice actor to voice multiple side characters, I guess to reduce the total number of voice actors that need to be hired (e.g. from this season, Fukuyama Jun voices Hunchoceratops and a few side characters in Amagi Brilliant Park; and Kayano Ai voices a number of side characters in Shirobako). But two different main characters? That's weird.
Weirder still, Sakurai is severely playing against type as Hinakawa - soft-spoken roles just aren't what he does, for the most part. Do we know why Sakurai was recast as a different character in Psycho-Pass 2?
