this symbol is used by the longtail clans. the coloration of the tail and background differ from clan to clan so as to not have confusion. they are usually the fur color of the clan founder and the appropirate compliment. this one specifically is used by Kyne's clan.

and please, ask before using for anything, i will most likely let you use it, just ask first.

AND BEFORE YOU SAY IT: this is not the Naruto Chakra focus patch. this is not based on the Naruto Chakra focus patch. i came up with this LONG before i saw Naruto for the first time, and it only looks similar out of sheer coincidence, so DO NOT comment if it is to point out this fact, thank you very much.
