Fire Release: Empire of the Sun

Fire Release: Empire of the Sun is an extremely high level ninjutsu. The user begins by creating a fireball, then increasing its size by adding more and more chakra to the fireball. The more chakra that's added, the bigger it becomes, but it also becomes more difficult to control. At its peak, the fireball can swallow a small village in its size. This amount of chakra to control is incredibly difficult, and if it fails, the fireball can drastically injure, or even kill the user, and is best used at its maximum as a last resort technique.
