You mean the same name as the technique from Dragons Rioting? Well, here is what I translate from it.

Ryūha (流派) means "school".

Koei (孤影) means "lake shadow".

Sōgetsu (蒼月) means "blue moon".

You can pair these together many ways, but as someone that doesn't speak Japanese or read it natively, I can't tell you honestly what the translation should properly be. If you wanna take a crack at pairing them up together so it sounds like a fluid name, you can give it a shot.
