Ninigi

Ninigi is a powerful, one-shot ninjutsu that derives it's power from pure natural chakra. Seireitou causes a large cumulonimbus cloud to appear, using a fire style to heat up the air above him; this leads to a wind style technique being used to create a tornado within the supercell clouds above. Lightning generated from the supercell thundercloud, the Sun's heat that lies alongside the top of the cloud, and the atoms of oxygen and nitrogen that fill the atmosphere all contain spiritual energy within them. Pure untapped spiritual energy, that when mixed with the tornado that supplies the physical energy, allows it to turn into pure chakra. In short, Seireitou can turn the sky's mass into pure chakra, and direct it's power towards his opponent. Because of the intensity of pure untouched chakra, and it's mass being so great, it easily outmatches all other ninjutsu (even that of Amaterasu) in terms of force. However, the preparation time required also decreases the technique's efficiency. Seireitou states that it's speed is even faster than lightning, making it seem like the blast actually teleports from the sky towards the opponent. The force generated from the burst actually sucks everything in, leaving no hope of escape.

To initiate a great thunderstorm such as a supercell, and then to take control of it's untapped unstable spiritual energy and mix it with physical energy from a tornado; that not being enough, to guide it down towards an opponent while changing it's appearance with shape manipulation drained Seireitou of his and Kyuubi's remaining chakra. However, once this is taken care of, the actual manipulation of the two energies takes little effort and chakra. In addition, usage seems to destroy the thunder clouds as the sky cleared up of clouds after use. As such, this technique can only be used once in a fight. The blast, however, was powerful enough to even break through Riyan's fully awakened Susano'o and still deal him great damage. Seireitou even claims that if it was not for Susano'o, Riyan would have been killed. According to him, when Ninigi strikes an opponent with the full brunt of it's power, it actually initiates a reaction within the body's atomic structure, and turns the target into a human bomb. On top of being struck by Ninigi's pure chakra, and causes their body to react in such a way, will cause their cells to disinigrate upon the aftermath of the blast.
