Akushiro the two tailed wolf

Image of the demon sealed within katsumi. her name(yes, the demon is a girl) is akushiro. she is a two tailed wolf with great intelligence,wisdom, and creativity. what little power she has(two tailed demons are obviously weaker than nine tailed ones) she uses in ways that allow her to maximize the damage it produces. she has quite a bit of physical strength(enough to go toe to toe with gamabunta)...at least in my story, akushiro, after being sealed into katsumi's body, took it upon herself to care for and guide her as if she were her mother.
