NieA

 
Originally, NieA was called "Endohana Spings". She was dual booted with Windows 98 SP2 and Mandriva Linux. I named each after a character in the anime NieA_7 ("NieA Under Seven"). Windows was the formal although stressed Mayuko, and Linux was the eccentric NieA.

Eventually, I came to use Linux as a primary OS and dropped the name Mayuko.
