A member of a gaming group I was a part of had a long-lived tabletop roleplaying game character, a ninja from far-eastern lands using the name Rei Nakaumra.

Of course, the thing about being a ninja is that others aren't allowed to KNOW you're a ninja, not even those you travel with. So I whipped up some "cover story" documents for the player to print out and use as a character prop.

Since I wasn't restricted to real-word ideograms, I got a little whimsical with the look and feel.
