Actually, only one exists, and it's wielded by Rena the Mew, a Mew that was a goddess before she had her powers takem from her by Arceus, this sword is her only method of self-defense and of fighting at the moment, plus she can't float around or transform. The colors on the real sword would be temporarily missing until the powers are recovered, oh, and I'm sure you've heard of the 16 plates, those contain pieces of her powers.

that looks awsome

Looks pretty good!
