The name sounds beautiful. If you playing a straight tribe born Xaela, its a little bit of a stretch, but if RP wise she is meant to be a Raen, then I see no reason why there is any problem. Having being raised under the Ruby sea is that adorable tiny village makes her naming scheme make even more sense. Just because the Japanese name is a reference to a mythological figure you like doesn't mean that you can't use it. She isn't a goddess in this world.Â
A big take away though... RP how you want to RP. No one here in this thread thinks your name is non-canon, and people are not going to shun you RP wise for it. I am sorry that your friend is being judgemental regarding your name. Someone could easily name their character Amateratsu and it be perfectly fine because... they aren't a deity in this world. However, I love the concept of a Raen from under the Ruby Sea!
