Nine Tails

"A ninetails is an arrogant fox spirit, but with good reason. Few can withstand the powerful magic this spirit can conjure." Each tail a fox spirit has indicates its strength, all the way up to nine tails, and as such Nine Tailes are usually the most powerful foxes found in the world, with the exception of foxes such as Yomi who have amassed power over thousands of years through their own hard work.
