Just a question that's been bugging me for a while, what are the correct way
to spell some of the names?

Ukyou or Ukyo?
Ryouga or Ryoga?
Kunou or Kuno?

These names are spelt both ways by people, although strictly speaking,
Ukyou Ryouga Kunou are the correct ones. In Japanese there are long o's
and there are short o's. In the hiragana alphabet, there are a bunch of
characters, each of which can be written out in romaji (i.e. with English
alphabet). 

   ,       |          ,
 /---    --+--      /---
/    \   --+--     /    \
    /   \  |  |        /
   /     \_   +--     /
             _|_
            /_|

or

U ki   u
    yo

is how "Ukyou" is written in hiragana (yuck that ASCII looks horrible).
That final "u" is not pronounced as such, but is used to indicate that the
"o" sound in "kyo" should be elongated.

If we removed those "u"s when writing romaji, it would be unclear which
"o"s are long and which are short. However some writers remove the "u"s
because they confuse readers trying to pronounce the names.

also:

Mokou-Takabisha, Moukou-Takibisha or Mouko-Takabisha?

Mouko Takabisha

Hiryuu-Kouurin Dan, Hiryu-Kuurin Dan, Hiryuu-Shoten-Kuurin Dan, Hiryu-Kourin
Dan?

If you're talking about the Rising Dragon Ascension attack, I'm
pretty sure it's

Hiryu Shoten Ha

but I may be wrong.

Confusing ne? ;)
