Oh, I just adore that this happened at all. It's really lovely! And so nice to see a passionate VP. I think Po-uta is a fun name for the Japanese pun, and doesn't sound too bad in English if you treat it like Japanese rules ou = long o sound? Sorta? Almost like Porter but without the R. Or just, how you might say his name if you had a particular accent (British? Idk, I hesitate to say since I'm bad at placing accents).
I've been putting off buying V6, but this has me sorely tempted. I'm not actually mad at him being a purposefully robotic voice, and I've seen a few samples (form mixing gods, no doubt) that pulled off a pretty natural sound, too!
