(NOTE: The "竜" kanji reads as "Ryuu" in 'kun'yomi' when used by itself. If used as a compound kanji, which is by combining with another kanji, it is read in 'on'yomi' as "-ryuu," "-ryou," or "-rou.")

(NOTE: On the other hand, Mogura "土竜" is an irregular kanji that has its own special reading, exempting 竜's on'yomi from the reading.)
