Making an Anbu charecter became very easy when Gaia released the Dark Star and Ancient Katana. Gaia seems to have caught onto the whole Ninja/Pirate thing...
Anyway, the basic uniform for Gaian Anbu has been described by
Kakashi[DUI] (without the mask and katana) Since the mask is UBER expensive, hardly anyone can get it -angry cough at Kow- so we don't care if you don't have it. If you do get one...good for you...I hope you die...
Anyway, you don't have to limit yourself to the standard uniform. In this guild, we promote creativity. be what you want to be. You are your own Anbu Agent, so let your imagination join forces with tek tek and see what you can cook up.
