English Vocaloid Voicebanks in Need

How's it going, folks? I'm Kimberly AJ and I'm checking to see if I can solve the mysteries of the unnamed voice actresses of MAIKA and Prima. And as you can see, I also inserted that MAIKA's voice actress is supposedly from Spain. As for Prima's, I just need to find out which nationality she is from.

SeeU (offscreen): Kimberly!

Kimberly AJ: What is it, SeeU?

SeeU: Kimberly, I want to have an English voicebank, but somebody had cancelled it!

Luo Tianyi: But she's not the only one. *focus on her* I want the same thing.

SeeU: Where's my English voicebank?
