25 Storm Release

After joining Root, Ren had gained access to lots of its training facilities, research centers, and libraries. Standing in an empty training facility, Ren was trying to fuse his abundant lightning chakra with the little water chakra he had. Ren knew that by combining the two he would be able to achieve the storm release.

Storm release was a combination of lightning and water, it was used by many shinobi from Kumogakure, most notably Darui. Ren had much respect for Darui as he later became the 5th Raikage and excelled at lighting jutsu even though he could use water and wind release. Despite the Storm Release's name, it did not control actual storms but instead manipulated beams of electricity to make it flow like water.

As far as Ren knew, there were four different jutsus that used storm release, however, he was only interested in two of them. The first being Light Fang which was a sharp thin needle with extreme piercing power. This jutsu was a perfect fit for assassination. However, it required Senjutsu to be infused into it to keep its form, but since Ren currently did not have Senjutsu learned he could not learn this jutsu as of now. Thus, the only Jutsu he could learn was Laser Circus, one of Darui's main techniques he used in the anime during the Fourth Shinobi World War.

"Rat, Tiger, Dog, Snake, Dragon. Storm Style: Laser Circus!" Ren said as a halo of energy appeared around his hand, before encircling both of Ren's hands. Feeling the chakra group up in his arms Ren released it all out in a wide area in front of him. Completely destroyed the training dummy with the few beams that hit, Ren thought What would happen if he focused all the beams into a single compact beam.

Trying his idea out, Ren formed the same hand seals as he shot a huge laser out, completely decimating the area.

"This Jutsu is extremely powerful, but it uses almost half of my chakra. Compared to Chidori I can only use this twice maximum, it would be better to save it and use Chidori instead." Ren mumbled.

Running out of chakra, Ren decided to take a short breather before returning to train. But, instead of using storm release, he uses the Lightning Beast Tracking Fang, transforming the lightning in the user's hand into a hound, then launching it. If you attacked a string of lightning to it, you would be able to manipulate and control the speed and range of the technique. This would be the perfect move to stall for time as it didn't use much chakra but was still dangerous if not taken seriously. This was a move Kakashi Hatake had used often.

...

As Ren was testing out multiple jutsu, he heard saw someone in a black coat and an animal mask to cover his identity. Ren was also in the same suit, but he had the mask hanging down the side of his head.

"Lord Danzo has assigned you your first mission, return to the main headquarters to receive your mission." The man said with a solemn tone, but looking at the damage Ren had caused, especially the damage from the Laser Circus the man was filled with shock as he spoke with a slightly more respectful tone.
