Mystery Unravels

Danzo looked around the library that used to be his and saw books scattered all around the place. Order long forgotten.

"You should clean up this place..."

"No, I don't. This place is perfectly chaotic. Now, what do you want?" Fuzen put his book down and leaned forward to faze Danzo with one hand resting on his chin.

"Like I said. I'd be taking control over your training, and I believe we should move on to the next part of the training and you to start learning more about that bloodline," Danzo said unfazed by his combative attitude.

The fact that Danzo never got triggered, pissed Fuzen off. A better person might admire Danzo for possessing that quality, but Fuzen wasn't a good guy, so he hated it. He did agree with him though. It was time to begin this stage of his training.

However, when they began the next day something strange happened.

After he demonstrated the ability to move between shadows two years ago, they knew Fuzen had some kind of bloodline ability. There was no other way to explain how anyone was able to do something like that. While it was rare for someone to be born with a bloodline ability, it was another matter altogether to have one never seen before.

To find out more about Fuzen's bloodline, Danzo made him test which of the five basic nature transformation his chakra showed an affinity towards.

"Hmm, that wasn't supposed to happen," Danzo mused after he saw it.

Surprising both, the entire chakra paper had turned pitch black and wrinkled itself until it formed a small ball that eventually disintegrated into nothing.

Fuzen took another chakra paper and tried again. The same thing happened.

"I can't," Fuzen said.

"What do you mean, you can't? Explain."

Fuzen tried his best to describe what he felt happen when he channelled chakra into the paper.

"I mean, it doesn't work! I keep channelling chakra into this shitty paper" – he looked at it in irritation – "and it feels as if whatever reaches the paper is a fused product outside my control."

"Fucking piece of shit!" he cursed his frustration at the papers hadn't used.

Danzo had never considered the possibility of the chakra paper reacting like this. However, after convincing Fuzen to continue doing the test, he theorized Fuzen's bloodline most likely combined the elemental chakra natures of earth, wind and lightning, and somehow his yin release intervened and fused them together to form a single element.

It was a bit far-fetched, but it was the only explanation Danzo felt might explain Fuzen's instinctual use of chakra transformation. On the downside, if he was right, it also meant he'd probably never access any of the other elemental chakra transformation inherent to his bloodline as they appeared to fused to create a new element.

He wasn't quite sure how to categorize it either. If it was only the three elemental chakra natures, it would be a kekkei tota, but if what he assumed was correct regarding the addition of yin release, then it'd be an unheard mix between elemental and non-elemental chakra transformation.

Danzo had been silent for quite some time now and appeared to be in deep thought.

"What are you thinking?" Fuzen asked. For once genuinely interested in what he thought. Danzo did have much more experience when compared to him in this department.

"Okay, there's some good and some bad news..."

"I want the bad news first!"

"The bad news is that I don't see you ever using the normal nature transformations and as a consequence will have to develop your own arsenal of jutsu from scratch."

"And the good news?"

"Well, the good news is that you have a bloodline that no one yet knows how to counter and with the addition of yin release, it appears to be a very flexible bloodline, meaning your future limit using it will only be restricted by your skill in shape manipulation and imagination."

That was good news indeed, Fuzen thought. And the bad news didn't discourage him in the slightest. Knowing he only had a single path to power made his ambition burn even brighter and determined to excel even more. He liked the aspect of creating a new path unseen to this world.

To most shinobi the first step would be to learning how to mould and define the nature of their chakra, however, as that came naturally to him, it wasn't necessary. Together Fuzen and Danzo began experimenting on the properties and characteristics of his bloodline's specific nature transformation.

Initially, Danzo went with the assumption his bloodline was an improved version of the Nara Clan's ability to manipulate their own shadows through the use of Yin Release, but it turned out to be so much more.

It took them several months to build a preliminary understanding of his bloodline. One of the primary aspects they had discovered during this time was that any future jutsu he created was always going to have a foundation in the darkness contained within his own shadow.

The fortunate thing was he would always have access to the darkness within his shadow as it could never truly be erased. Darkness was indeed one of the few constant factors in this world.

Knowing this, they brainstormed ideas that would support and enhance his already current skillset. That meant it should enable his taijutsu prowess to excel even more. Danzo wasn't of much use during this phase and often just sat on the sideline watching Fuzen struggle and curse to himself. Danzo did make an excellent test-subject though and helped point out some errors in his thinking.

It took a while, but in the end, Fuzen ended up with a jutsu called 'Black Sea'. With himself, at the epicentre, he would use shape transformation to expand the darkness within his shadow in a circle around him. Within this field of darkness, he had figured out how to increase the downward gravitational force on opponents to a noticeable degree thereby making them slower and him appearing faster. He already had ideas of how its uses could be developed further when his shape transformation improved. As he wasn't yet very proficient in its use, both the gravitational downforce he could exert, and the range that currently maxed out at around 20 feet could be improved a lot. It wasn't quite a sea yet, but in the future, he would make sure it would be.
