Thunderbirds

Thunderbirds (雷鳥, Raitori) are ancient birds, that once fell under the dominion of the Storm Dragon. Existing alongside the Shinju, they essentially served the thunder dragon for centuries. Able to transform electromagnetic energies, and create lightning storms, thunderbirds have been coveted by lightning masters, magnet masters, and Date Clan members alike.

Communing with humans, those who could control and tame them became legendary lightning users. Gaining their favors meant gaining powerful allies, and stronger powers. Able to control thunderstorms at whims, spiritual powers, and more. However, following the First Mizukage slayed the Storm Dragon, nearing the end of Warring States, taking its fangs, to create the Kiba swords, the thunderbirds withdrew from the world, offended. Waiting for their dragon to return...

As each wielder of the Kiba swords utilized them, they indeed gained part of the powers granted by Thunderbirds, and by extension the Storm Dragon. Allowing for them to create thunderstorms, and absorb its energy for never ending battle, making them feared as Warring States ceased. Users that have accomplished this lightning prowess, also include,, and.

But as the swords lay in Kiri, none could fulfill its true potential, and the thunderbirds lay dormant, hidden from the world, their legends forgotten. They grew offended at the wielders of the swords, who didn't understand what they were connected to.

However, they would not be forgotten forever. The dragon spirit still lingered, unable to find peace. Essentially the "essence" of the Kiba swords, he never felt the best connection with any wielder from Kiri, as Lightning affinities were uncommon there. And known shared its love for electromagnetic energy, and thunder, and storms. Until, the Kiba swords wound their way into Kumo, and eventually, were handed to Kei Yotsuki.

The dragon took a liking to this fellow, who was dedicated to Lightning Release, among other things. This dragon, would reveal himself to the Lightning Master, after he was given the swords by Omoi. Essentially revealing the story behind the swords, Kei agreed to use the swords as they were meant, to be the fangs of the true dragon. Merging in "essence" with this dragon, it gave him "Lightning Dragon" abilities, among which, a contract with the ancient birds of legend. Allowing for him to bring back them once more. Turning them into characteristic summons, along with Jellyfishes, much like Itachi with Crows, or Jiraiya with Toads.
