The answer is both! Whatever you feel like, I answer to both.
Kacey is my real name
Keshi came from a nickname in high school. We all put our names into a "name translator" to see what our name would be in Japanese. I got Keshi and it stuck.
I use it as my art name as well, mostly online and at conventions: KeshiART. I may change it in the distant future but for now I like it.
Funny enough, I apparently share the japanese name of Abra!
