Not that I'm aware of, no. When typing, both in Hiragana and Katakana, there is no mention of "u" except for the sound, since the "u" alone coundn't go on the word as a kana. But anyway, you may be right, since I only know basic japanese. End of discussion, it is a nice transcript.  

Btw, Ashtarth's title rules! "Bakufuu Oh", uh? I wonder how did you find out it was "King of the Wild Wind" since Bakufuu can also mean "blast" and "explosive wind", lol. Sigh, I'm far from mastering japanese. ;__;
