Awesome, thanks for relaying it here! Now we need someone to translate it.?
Not perfect as although I can understand it I have no idea how to properly translate it back to English, but here I go.
Mayuri: tuturu~. Hey hey, listen. Me and Kurisu are going to...
Kurisu: Make some kareage!
Daru/Okabe: . . . WHAT!?
Okabe: Out the way! If you do that the lab will fall into the depths of hell!
Daru: It won't be pretty!
Kurisu: I think you're over-exaggerating
Mayuri: It's fine. Today we've got a secret weapon!
Okabe: A secret weapon?
Kurisu: It's nothing that'd come from your chuunibyou imagination, it's this!
Upa: Hello, I'm Upa! I'm a cognitive computer attached to a personality!
Okabe: Cogni... hmm, so you're saying it's going to help us?
Upa: Yes! I'll support you.
Upa: Preparing the ingredients, how to cook them, one point advice etc, etc. (something I can't make out), I'll become your servent.
Daru: Well, like this it could be fine couldn't it?
Okabe: Understood, let's believe it.
Okabe: Upa! No, Cognitive computer yo! Show me you can get my assisant and Mayuri to make the perfect food!
Kurisu: Why are you so self-important...
Mayuri: Well that is Okarin...
Upa: Well then firstly, I'll present the recipe for karaage.
Kurisu: Bird leg meat, flour, potato starch,
Mayuri: Then we have osake and soy sauce.
Kurisu: Let's get ready!
Mayuri: ok!
Okabe: well... what are these?
Upa: Beef, Chocolate, Apricot puret, Eggs, Banana etc!
Okabe: This is completely different to what's required for karaage isn't it?!
Daru: This is awful...
Mayuri: We didn't have the right ingredients in the lab...
Okabe: Then wouldn't it have been better if you went and brought it?
Kurisu: It's strange... we didn't have any flour, but we had apricot puret which is kind of rare... who had... eh!? Hashida!?
Daru: If you're wondering why I had it, if I ever got a girlfriend then there's a chance she'd want to cook at the lab right?
Kurisu: Forgetting Hashida's delusions for a second, no matter what theory we had it's impossible to make karaage with this.
Okabe: ... that's why I said go and buy the stuff.
Upa: Well then! Let's think of something else to make with it.
Mayuri: Amazing? You can do that!?
Upa: Leave it to me!
Mayuri: We did it!
Kurisu: It's finished!
Okabe: and this is?
Upa: a Chocolate Burrito.
Daru: Looking at it I don't think it seems so bad...
Mayuri: I know right!
Mayuri: Okarin, Daru-kun, give it a taste!
Okabe: hmmm, fine. You two did all this, so let me decide the resolution. Daru, you can go first.
Daru: You said all that to pass the buck to me?
Okabe: Oi... you said just now you you didn't think it looked that bad didn't you!?
Mayuri: Okarin... if you really say you hate it that much I'll be reeally sad...
Okabe: F-Fine... it'll be ok if I eat it right? If that is!
Okabe: It's delicious...
Kurisu: Of course it is! You were worried too much.
Okabe: It's me, somehow it appears I've seen an illus-, no it appears I'm enjoying the taste of something great. It's a possibility that this is an agency trap
Kurisu: Good grief, you haven't changed at all have you...
Mayuri: This is all thanks to upa-san!
Okabe: El, Psy, Congroomai. (a pun, umai being delicious and Congroo being Konguru(mai))
