is this for a derogatory remark
joo = queen
ryu = dragon
so whether its jooryu or ryujoo i wouldn't have a clue but i go with the first one
The Japanese word for Dragon is "Ryuu"
Doragonfurūtsu
ドラゴンストライキ
reinas ladronas
Kagami Ryū
ginryu
'Kinzoku no ryuu'.
ryu no ha
ryu-ken
Doragon iki
to say dragon in Japanese is 龍 and it is read ryuu hope this helps :)
'Small dragon' would be 小さい竜 (chiisai ryuu) in Japanese.
