... Dude. Not to be offensive or anything, but you know desu is a particle in Japanese, right? Pretty sure it's not a valid name. But honestly, it make's about as much sense as naming your child "is" or ".".
Okay, today my tact is horrible, so this may come out wrong... But uh... I just read the project thread... Eeeeeehhhh. Isn't there a more original and valid way to include "desu" in one's name?
