Yatagarasu

Appaerence
Yata-garasu is a really big pitch-black three-legged raven. Its size surpasses any dragon or superior dragon that Tomoe knows. Its claw and beak are sharp.

Character
It seems that Yata-garasu serves as Gods' mount and seems docile however as the incarnation of the sun it seems to be pretty brutal toward those who are unworthy to look upon, like grasping and crushing them like a lit cigar. He is the favorite pet of the Godess of the Sun, Amaterasu.

Etymology
"Yata" seems to mean "large" or "eight-span", which I suppose is supposed to be descriptive of its size however even for Misumi Makoto it seems to be too huge.
