LOL, at around 3:15 they show Ludvig Forsell, the co composer along with Harry Gregson Williams. A rough translation of his first few lines are "Hello, Hello, Hello (technically saying thank you, sort of but w/e), hello everyone (in Swedish) and how do you do? I am Kojima Production's weird/funny white guy, Ludo (a simpler way of saying Ludvig, since it would be hard to pronounce for a Japanese person)! *something something something* He says something about Sweden (as a giant text pop-up labels him as Swedish) *something something* music *something* pleased to meet you!
It's obvious he is talking in an intentionally off accent and his "DOMO DOMO DOMO/HELLO HELLO HELLO" is completely over the top. Sort of funny seeing a foreign guy working at Kojipro, ultimately I'd like to work at a Japanese video game company, but it may not be practical.
