Achaeos is a pleasant kitsune of indeterminate age. He behaves with the free-spirited nature of one young, but possesses an air of wisdom that would be more at home on someone older. Fond of warmth and fire, he often carries with him a traditional-style lantern, through which he can channel his fiery powers with greater ease, by utilising existing flames as opposed to creating them from scratch.
As a kitsune he can take on both human and fox form. In his fox form he has dark-brown/black fur and nine bushy tails, with patterns trailing along his body. In his human form he conceals his tails.
Unlike many kitsune, he does not rely on the souls of humans to sustain him, especially not through sleeping with them. Instead, passively spending time around those of other races with more 'wholesome' souls is enough to sate him and keep him healthy. He is however capable of using his powers to manipulate and drain the souls of other beings if he wishes to, which is seldom, as he considers it taboo.
As well as his lantern, he often carries with him a small white orb, his 'star ball', which contains a portion of his magical power and soul. To be separated with it is to lose much of his sense of self, and he will go to great lengths to be reunited with it..
He is capable of manipulating the minds of most mortals, and is resistant to such powers himself.
Aki hates dogs with a passion, and cannot stand to be around them. He holds similar disdain for wolves, albeit less so. Werewolves and werehounds are not as abhorrent to him, due to their greater sapience and intelligence, but he still does not like them.
Achaeos' past is a mystery he has yet to tell another being. He has flitted from place to place for much of his life, seldom settling down for more than a few years at a time. He has made friends in many places, and enemies in others. He has a strong sense of justice and a desire to leave a trail of good wherever he goes, and will stand up for those who need him.
