This is most canine-like form, known as Okammi (yes, pretty much the japanese word with an extra 'm'). The biggest difference between this form and the Yajumi form, other than being obviously quadraped, is that the marks on over his eyes are different, his crest of fur is even longer and the white fur is also on his bum ^_^

Yajumi are part Yanumi, which are basically the Shi'Imoran equal to our Earth's wolves. Infact, the name Yajumi is derived from the name Yanumi. All just fancy Shi'Imoran laguange XD

Yanumi themselves differ from earth wolves in that they are not only larger and have the ear flags, but also have much thicker bone stucture, bigger paws, long tufted ears, fluffier fur and a crest, as well as elongated canines and claws. Their markings also tend to be different, though actual coloration is naturally similar.

Yanumi also tend to be sepient and able to speak.

The Yajumi okammi form is same as a yanumi although larger. Of course, Yajumi like Niki, often dye their hair/fur, while Yanumi do not.
