Demon Wolf Transformation

Kyashi Urami is the container of the demon spirit Kyosuke. When she taps into his chakra, it increases every physical aspect of her body: Near-limitless chakra, massive strength, increased speed and stamina, and increased healing. Kyashi has access to Kyosuke's chakra due to an incident that occured when Kyosuke tried to control Kyashi's body. Kyashi was able to push him back with pure willpower, however, and Kyashi, impressed, allowed her to access his chakra reserves, although he forces his chakra on her when her life is in danger.

Primal Form
By simply tapping into Kyosuke's chakra, Kyashi's blue eyes turn red, her pupils become slitted, and her nails and canine teeth grow long and sharp. Kyashi first unlocked this stage when almost killed by Rain bandits at the Fire Temple. Depending on how much chakra is unleashed, the crimson chakra could glow around her body in an untamed way.

Even though this is the weakest state of her transformations, it is still a force to be reckoned with. Stronger than Naruto's Jinchüriki form, this heightens the senses of sight and hearing, quickens her body's healing of wounds, and increases her speed to such high levels that even a fully mature Sharingan cannot track her movements.

Berserk Form
During Kyashi's battle with Naruto in a forst not far off from Konoha, when Kyashi was at the mercy of Naruto in his One-Tailed state, Kyosuke used his chakra to transform her and push her into the second form. The chakra amount is so great that it leaks out of the body at a denser rate. All the features of the Primal Form are present, although slightly modified, including long and sharper nails, claw-shaped hands, and visible lines under her eyes that run along her face. But there's a big difference: The red chakra shield silhouette around her body, protective from nearly any attack.

In this form, Kyashi fights more like a beast. Instead of fists, she uses her sharpened claws. She can run at a quicker speed on all fours. But the most powerful feature is the chakra itself. Kyosuke seems to have control of it, able to extend it: When Kyashi was punched in the face and stunned, the chakra extended from her stomach and hit Naruto before he could react.

Demon Form
During Kyashi's fight with Sachi, the two proved to be evenly matched. When that was apparent, Kyashi's fury increased, and she transformed into the final form: the Demon Form. In this transformation, Kyashi's skin and yes turns black, her pupils are crimson, and her strength is increased even more. In this form, Kyosuke has total control, and Kyashi loses her consciousness. With a thrust of his hand, Kyosuke can cause a devestating shockwave that extends for miles. He can also create a concentrated chakra ball and fire it at his target with such force that it could destroy an entire mountain range. Finally his skin is so thick that it is impregnable to any attack.

However, despite it being Kyashi's powerful form, it's also very risky. Because Kyosuke is in control, Kyashi is blatantly at his mercy. Kyosuke could easily take full control of her body and trap her into her own body, although he has never tried to. Also, the form uses nearly all of Kyashi's chakra, so when Kyashi returns to her normal self and has full control of her body again, she immediately falls to the ground in a state of near-death.
