Hi everyone! I'm Reo, new to Battle Rondo and here. I'm living in Japan right now for studying.
and it seems my english is getting broken.... well nice to meet you all!!

Some question about the CSC, I had just recently bought a Arnval Mk.2 and Sharatang(Violin) but don't know which CSC is the best for them.

I'm now thinking of getting the rare CSC which are the Moonstone, Cat's eye, Black opal...etc for them is it fine with that?
