Blaze Release: Kitsunebi

This technique is the ultimate ninjutsu of Yoru Uchiha, and he is the only known shinobi capable of mastering it. In the palm of his hand, he supercompresses blue flames into an extremely dense, yet small spherical form. Once he has taken aim, he discharges the sphere from his palm, launching it towards his target. Upon impact, the blue flame spheres expands rapidly and then explodes, incinerating anything within its massive immediate blast radius. Its destructive power is said to be enough to completely destroy an entire small village. Fittingly, it also requires the expenditure of a huge amount of chakra.
