I swear to god, I already posted in this topic, or...at least, I thought I had.
Guess not?
Kaoreii - Actually, Kaoreii was a typo. It was supposed to be Kaorei, but on the first RO server I actually started to use the name on, I typed too fast, and entered two 'i's. Turns out, I like it with two 'i's better than just one. As for where the name came from, I honestly don't remember. I think I was just...playing with sounds in my head. Trying to find something that sounded nice. Not that any two people pronounce it the same anyway.
Seraphim - Angel. She's a priestess. 'Nuff said.
Tiana - I've been using this name for lonely redheaded tragic characters since god only knows when. So where I picked up the name, I have no idea.
Xiaomei - It's a pretty chinese name. :D
