Same happened with SCV Nightmare: the tone is different (and malfested xD) but you can hear quite clearly Charles Klausmeyer. So I too believe that it's the same VA but played differently in order to stick to the character's personality/age/story.I first thought she had a different VA, but listening to it more it does sound like her SCIV voice but toned differently. Especially with her grunts and screams, she sounds very different. However, I do think the VA may be the same.
For Mitsurugi though his voice does sound completely different, I hear Matthew Mercer too as someone else previously stated.
