A: I am Korean, born to Korean parents who were born in Korea, raised speaking and reading Korean until I went off to school. Let me know if this isn't "actual Korean" enough for you.
B: Your own sound file through your own admission says Gir and not Gar.
C: Using screenshots of content attained through yourself, some others and gameabout;

Let's focus on where his name shows up:

Or in direct characters, 기루가쉬.
The observant will note that the vowel characters in the first and third sets/syllables are different. Well that's great, how about some reference?

With this handy dandy table you too can romanise Korean.

These two are the typical "a" in Korean, alike to the a in "spa".

This is the other "a" sound in Korean, the pronunciation of this one is more like that in "bat", "happy" or according to wiki, the e in "bella" if you're Spanish.
The observant will see that the latter character isn't present at all in the name though the former character is present in the third set/syllable. So that's definitely a "ga".
What we're after is this:

Like it says on the label, this is the "i" sound in Korean, like the y sound at the end of words like "bunny" or the ee in "free". Using ocular magic we can see that this is in fact the character that is paired with the "g" in the first syllable of the boss' name.
While I'm at it, let's go the whole hog and look up how to romanise the entire name:

So let's see, gireugashi? Wow it's almost like I can fluently transliterate Korean or something.
EDIT: Bonus, his name in Japanese is ギルガシ. I'm sure Nation has enough Japanophiles that I don't need to transliterate this too.
