Just a heads up, any voice actors from Sony owned Funimation/Crunchyroll might be out of the options for SEGA's payroll under current conditions.
Well... to be more precise, SEGA went with lesser known voice actors who fit rather closely to the vocal range of the JP voice talent.
While it is cost effective, and isn't going to be a perfect match, there was one voice talent I did vaguely remember hearing about.
Not sure where I heard the name Carolyn Miller from, but she's somewhat noteworthy. (And is now voicing Tetra.)
Plus, there's the fan backlash of both companies making big script changes to the localization, so I believe it's within SEGA's best interest to continue scouting as they have been.
Do we really want SEGA to have the same repetitive voice talent in Funimation? I don't think so, and they're getting kinda old, too.
I'm excited to see new voice talent that I don't recognize, because that's what makes it so interesting.
