Jet

Jet/Urushi is a wolf magic beast familiar that was summoned by Teacher. He was originally summoned as an Onyx Wolf; however, due to the excessive amount of mana Master used when he summoned him, Jet evolved into a Darkness Wolf after he was "christened" with his name.

Like regular Darkness Wolves, his fur is completely jet-black. However, he also has some red mixed in around the edges; this, along with possessing a Unique skill, classifies him as a Unique Individual.
