Naruto: The Wind Calamity

A wry smile appeared behind Fujin's mask. The advantage that the jutsu had was itself a lethal disadvantage. The jutsu was less of an attacking jutsu and more of a suicidal jutsu!

Fujin continued thinking, 'Due to the high chakra density, the jutsu can't be thrown at a great speed. Instead, it moves at a snail's pace and I can't even use winds to speed it up like I can with a normal Rasengan. Whoever uses this jutsu will definitely be hit and die along with his or her enemies. The only way to feasibly use this jutsu is by teleporting it through Flying Thunder God marks…'

One of the main reasons why Fujin had talked about Lightning having to be wild and unpredictable was to confuse the Kumo ninjas. Due to his words, they felt what he did was an application of Lightning manipulation when, in fact, it was a Space Time technique. Even though Darui and the rest had doubts, they suppressed them due to Fujin's words and convinced themselves that what they saw was a pure application of Lightning manipulation.

After creating the jutsu, Fujin merely teleported the sphere at a Flying Thunder God mark which wasn't neither too close to the Kumo ninjas nor too far away from them. This ensured that they wouldn't die but would be injured enough to make them take his threat very seriously and make several preparations to deal with 'Akuro' the next time.

Fujin thought, 'Hence, that jutsu is still incomplete. It's even worse than Rasenshuriken in this regard. Even though it doesn't hurt the arm like Rasenshuriken does, the user will be hurt way more than the target. That is why, even Sage Mode won't be a help to overcome this drawback.

Perhaps the Lightning Chakra Mode might help, though I'll need to test this jutsu on Ay in order to be sure. The other option is to learn how to control the direction in which the Lightning is launched after the sphere explodes.

Currently, only a fraction of the actual attack hits the enemy due to the omnidirectional nature of the jutsu. If I could control the direction of the Lightning after it explodes, it would not only remove the drawback but also increase the effective power of the jutsu by at least 2 times without having to spend any additional chakra. However, this is also very difficult because I'll need to modify the jutsu considerably…

Another issue, which I may not be able to fix, is that I can't amplify this jutsu with either the Blade of the Thunder Spirit or the Kiba Blades like other Lightning jutsus because this jutsu isn't like other Lightning jutsus. The presence of Rasengan is too big of an interference for normal amplification to work.

The only help I can get is with the Lightning that I infuse into the Rasengan. That can be amplified by the blade, saving me a considerable amount of chakra even though the amount of Lightning chakra lost during the process of fusing it into the Rasengan increases. So, the chakra I need to create Saisho no Hikari is around half what I need for Rasenshuriken…'
