Summoning: Double Suicide Reincarnation

A technique created by a distant branch of the Yamanaka Clan to create an artificial Ninja. Realizing that they had limited combat skills without the assistance of the Nara Clan or Akimichi Clan, they developed this technique as a fail safe if two of them were together instead of their Ino-Shika-Cho Formation Group.

Usage
In order for this technique to work, both users must simultaneously preform the required hand seals in unison as well as the same gender. During the the execution, dust, ash and rocks are collected from the environment as they begin to take the form of a sleeping person featuring both attributes of the users all the way down to physical features to clothing. Once the required hand seals are complete, the consciousness of the users are transferred into the new body, causing any imperfections to disappear as it awakens. The unconscious users continuously transmit chakra to thew new body in order to keep it activated.

Advantages
The resulting new shinobi will possess the combined strength and all abilities the users have, including kekkei genkai, kekkei tōta and summoning contracts as well as new ones as a result of having multiple chakra natures and kekkei genkai. Similar to the Reanimation Jutsu, the new body is impossible to kill by normal means. Any damage they receive will easily regenerate, be it lost limbs or complete disintegration. Although it's chakra will be limited to combined chakra of it's users, it has unlimited stamina, being able to fight without tiring. Having 2 consciousness', the it shall become immune to genjutsu, as well as mind manipulation techniques.

Weaknesses
Although a seemingly invincible jutsu, this technique only lasts for a maximum of 30 minutes. Afterwards the summon dissipates the consciousness of it's users return to their original bodies. However if one of the users happens to run low or out of chakra the technique can cancel earlier than expected. If one of the user's chakra is far greater than the other than the created body will explode before completion meaning the gap in power cannot be too great. Although the technique was created as an offensive fail safe, the user's bodies are still left unattended making it difficult to face multiple enemies if not guarded.
