A sealing jutsu. Summons Death himself, which joins with the actions of the user. The Death Lord reaches into a outline of a soul infront of him which is actually the summoner. When the user grabs the enemy, Death extends his hand through the soul outline and comes out from the stomach of the summoner. Death's hand goes into the enemy's stomach where from it literally rips the soul out. After the soul is pulled back into the user, the user says "Fuuin" which means "Seal" in english and this completes the seal of the soul in the user's body. This can be used until the user runs out of energy, and since it is a sealing jutsu, there is a price. The user pays the price with his life, which death devours. The souls of both the user and the target are kept in the belly of the summoning, and are enemies for all eternity. Apparently if the soul is not completely extracted from the body, Death can cut part of it and seal just the part which he has grasped. In Orochimaru's case this was his arms, which are now lifeless and unusable.

Souja sousai no jutsu
This technique is a murder-suicide technique. Both the opponent and the user must die. This is also why it is treated as a forbidden jutsu.

Katon, Karyuu Endan
A jutsu that sends a stream of fire towards the opponent, in the shape of a large dragon, from the users mouth.

Katon, Goukakyuu no Jutsu
A technique where the user builds up chakra in their chest and blows a large ball of fire from their mouth

Kuchiyose Edo Tensei
A very high level and forbidden summoning skill. The user summons the bodies of the person/people he prefers in wooden boxes with their name on it. After the bodies are summoned the summoner must insert kunais knifes into the summoned bodies. These knives nullify the summoned person's soul and give control of the soul to the summoner

For this summoning human sacrifices must be made so that the soul of those whom were sacrificed can tie the summoned to this world. One person must be killed for one summoned person. Two for two and so on.

Water Element, Water Dragon Blast
Creates a large dragon shape formed from a large amount of spinning water. The dragon form is sent towards the user's opponent for a powerful attack. This jutsu can only be performed when near a large amount of water.

Ninja Arts, Genesis of Rebirth
The user stores unused chakra. This chakra becomes compressed and sealed away in the body. When in need, the user can bring forth the stored charka for whatever purpose he or she wants it for.In Tsunade's case, she uses the stored chakra to instantly heal herself. Not only can the stored chakra heal every single organ in her body, it can also regenarate tissue that was destroyed. Tsunade also comments that because this technique uses her chakra to regenarate, she will "never die in battle."Shizune comments in her mind that there actually IS a limit to how much Tsunade can regenarate. She also lets us know that "to hasten healing is to shorten one's lifespan!"

Choujuu Giga
a very unique and artistic ninjutsu since this jutsu enables someone to animate ink drawings. and it really fits with Sai who loves drawing. Sai has to carry a scroll with ink and brush, he usually draws animals such as lions, birds, or snake. he can uses them as vehicles or weapons, however it's less destructive than Kibaku Nendou.

Jashin
an immortal jutsu mastered the userthis jutsu enables the user to kill his opponents by suicide. however Hidan needs to taste the blood of his opponent beforehand. anything that the user does to his own body will happen to his opponent's body as well. for instance, if he stabs his own heart, his opponent will die but he himself will remain alive.
