Lunar translates into Japanese as Tsuki No and is written as 月の.
Yami no kiba
kiba no sutoraiki
ching fang tooo
Ookami Kiba
ryu no kiba
It means moon fang, or lunar fang.
The Japanese language. For example, getsuga tensho means "heaven shocking lunar fang".
getsuga tensho i believe
The phrase 'Hell fang' would be地獄の牙 (jigoku no kiba) in Japanese. The pronunciation would be something like "gee-go-koo no key-ba".
The word 'fang' is 牙 (kiba) in Japanese. This is roughly pronounced as "key-bah".
I might be wrong but Getsuga Tenshou means heaven-shocking lunar fang. Since things are the opposite in the Japenese language, Getsuga means lunar fang and Tenshou means heaven-shocking, So it's like lunar fang heaven-shocking if you were to translate it in the English language. I hope I answered your question right.
