I think it's pronounce "Beh-lee-el"
If you think about the Japanese, they most likely had it written in Katakana which is used for English words, or other forgein words. So it would be written (if I'm right here) Berier(ru but small tsu after so hard sound). Atleast that's my theory so that's how I view and pronounce it. 3nodding I could be blowing steam out of my a** for all I know though xp
