I go by 2 names on here, Galiou and Tetsune.
Tetsune was an alias I created long ago for a character I made up. TECHNICALLY, you could call him my first original character that wasn't based off of me or a self-insert. I made him a twin to Axel's Other (who I named Lae before, and this was an AU anyway.) His name was all the Japanese sounds I liked xD I love the way the "Tsu" character sounds.
I've used his name for my Pokemon character now, and it's been a good alias since like no one uses it!
As for Galiou... She's my fursona! I was entering a contest years ago, and though I had her as a character already, she was only named after by DeviantART name... (I link to it. Not sure if the language is appropriate enough)
So! I gave her a name that I liked. c:
