I haven't check out the SDR english voices yet. Do any of them bug you? Idk, it has alot to do with the story or just for the sake of it. He's better than actual Togami tho.
Fukawa's, Fujisaki's, and Kirigiri's bugged the crap outta me to be honest. And Monokuma's voice actor was just NO. The voices for SDR2 are better, but Monokuma is still there.
