I’ve ever guessed that RxYxO and Katsuma are two mixed members. But as long I look for it, I’ve never found that there two mixed members in coldrain. If you know the link, maybe you can give it to me. Then, I’ll help you to make sure who are those two mixed member? How?
I’m not sure about this. But, I’ve heard that coldrain have 2 other half japanese members. May you make a guess who are they?
