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.

Kimberly: So you both do? I see. I'll just have to--

SeeU: Where's my English voicebank?! I can't speak a perfect English without it!

Luo: Me neither...

Kimberly: Don't panic, you two, I'll just have to find out who was responsible for cancelling SeeU's.

SeeU: You will?

Kimberly: Of course, SeeU, what else can go wrong? I will be able to beg those who've already cancelled it to release it for your sake so everyone will hear your perfect English.

Luo: How long will mine be released?

Kimberly: Just in a certain date, Luo, just in a certain date.
