Inugami

In Japanese mythology an inugami (犬神?, lit. "dog god") is a type of shikigami (式神?), similar to a familiar spirit, resembling, and usually originating from, a dog, and most commonly carrying out vengeance or acting as guardians on behalf of the inugami-mochi, or "inugami owner". Inugami are extremely powerful and capable of existing independently, as well as turning on their "owners" and even possessing humans.An inugami's original body stays behind when it leaves to follow its masters wishes; the buried corpse slowly withers and rots, and if the inugami returns after the body is no longer habitable, it may take control of its master's body, making it even more powerful. Possession by an inugami is said to cure sickness, or ill health; however, it also results in the possessed behaving like a dog.

The ability of this obedient dog spirit when it is summoned is to protect its master from attacks using its body and chakra itself.It is capable of taking full attacks and even able to withstand from the most powerful of jutsu such as Kirin and Amaterasu.The dog will defend the the user to the teeth by covering its ghostly self onto the user himself as a defensive measure and even use the body to fight for him and acts exactly like its master by the way he speaks and acts making it very difficult or the opponent to tell if their hits are effective or not.

As for an offensive approach the user can send the dog to copy a users apparent looks,power and even its jutsu.In order for this to be in effect the Inugami must make contact with the user or eat the chakra in order to assume the form and ability of its target(Drawback:If the Inugami makes contact with the opponent,Effects and sickness may be cured).It can then fight along side the user.If used in conjuction with Alchemist Brilliance or another Weapon copying technique.The user will be able to create an exact replica for the Inugami to use with the exact abilites (And Drawbacks.) The user wields.The second offensive ability is that it may shadow bind itself with the opponents spirit and take its form.When the Inugami does it may not be able to attack but it will still be able to defend the user and even harm the opponent it shadow binded its spirit.It takes the form of the user and there will be and invisible black chakra string tied to the Inugami and to the target.If the Inugami is harmed the person it is tied to will feel the exact same pain.Of course the user of this technique cannot harm the dog when it is shadow binding with its opponent unless it wants the attack to be deflected against the user himself.This tie may be severed by a person with a doujutsu who can sense or see chakra and must cut it with chakra in order to break the bind.

The huge drawback is that in order to master this technique,You must have had a dog summon or be part of the Canine's family in order to summon it to your aid.After its time of Aiding the user the Inugami will become vengeful depending on what type of purpose you used him for and will try to harm the user.If you used the Inugami for attacking purposes it will posses its summoner and drain his chakra leaving him drained for the whole day and un able to lose control of your body for a little while.It can cure poisions,effects and some sickness when it posses the user.Another person can end this trance if the Inugami is struck hard enough by another person while its possessing its user.If used for the defensive purpose,It will haunt the user for the whole day and inflict all the pain it felt slowly into the user himself untill he feels as weak and tormented as the Inugami did when it was in battle and can even leave you near death.If the person that used this technique is inexperience this celestial jutsu may even kill the user with these drawbacks.
