The perfect training.

Jiraiya winced as he moved incorrectly, his wounds from his battle subduing Naruto hurting him as he looked at Naruto trying to sit perfectly still on top of a earth board, situated on top of spikes that Jiraiya had created with his ninjutsu.

'This will prepare him for the future, and for an energetic guy like him, no amount of training will let him sit perfectly still.' Jiraiya finally found a training he could give Naruto that would help him emotionally mature. It was also a training that would force patience down Naruto's throat if he liked it or not. 'It took me decades to be able to master this training... and even more to be able to get the next step under my control.'

Even with Naruto's growth rate, he expected Naruto to take years to complete this type of training. To become perfectly still, and not twitch a single muscle, was training that even his father took years to master as an apprentice.

"Gaaaah!"

'Then again, Minato was a genius, a natural at this... Naruto is so much like me, he may never be able to fully master this.' Jiraiya smiled awkwardly to himself. He looked at Naruto as he climbed up the high spikes with another earth slab to sit on, before he got on top of it and balanced himself.

Sitting still.

Naruto was an abundance of chakra and stamina, for Naruto the act of sitting still went against his very nature. It was practically impossible to imagine that Naruto would be able to read the flow of his own body so that he could maintain dead stillness.

"SHADOW CLONE JUTSU!"

"Hmmm?" Jiraiya saw as several clones appeared, holding onto the spikes that surrounded Naruto.

"Okay you guys, tell me whenever I'm about to move... we're going to get this training down!"

"That won't work, you're not at the point where you can get distracted during this training and not move. No clones." Jiraiya popped the clones with rocks he threw. He expected Naruto to save himself when he fell, and forced Naruto to carve the stone slabs he broke out of the boulders that were created through the ninjutsu that he forced Naruto to create.

The Earth-wall, a jutsu so simple that even people without proper training in earth style could do with just knowledge of the handsigns.

Then he made Naruto carve the slabs out of the earth wall.

"Fine!"

-Days Later-

'Naruto seems fine... he's just sitting there... where did those spikes come from?' Rias sighed in relief when she saw that Naruto was just sitting on a slab on a spike, very high up in the air. He seemed like he was training, though she didn't know what training involved Naruto trying to be perfectly still.

Rias grit her teeth.

Over a week, and they hadn't even felt a hair of that thing that had caused that massive energy spike. Her brother had sent her letter after letter asking her if she was going to be okay, and the supernatural world seemed to be in an uproar that something so powerful just appeared and disappeared like nothing had happened. The massive chunk of the forest that looked like a god had scooped it out was one thing, but the fact that there had been a massive spike in human suicide and energies. Teenagers all over the city had passed out from the energy, and many of the adults who had not passed out, had killed themselves from just how corrupt and hateful it felt.

Energy so foul that even the non-supernatural could sense it, and so evil that it could anyone with weak mental strength to take their own lives.

She had to make sure Naruto was okay, he seemed okay at school, but she had been so busy she had no chance to see him after school.

"Huh..."

Naruto stopped being silent and still, and he looked around.

"What the hell... what is this wispy stuff in the air?" Naruto asked as he rubbed his eyes, swiping his hand at the strange mist he was seeing. He rubbed his eyes even harder when his hand just phased right through the mist over the air.

Jiraiya in front of Naruto blinked.

"... No..."

"Why can't I touch it?" Naruto asked as the mist faded out of his view, and Jiraiya's jaw just dropped the second that he realized that Naruto had managed to see something he should not have seen.

No.

He was looking at something that scared the shit out of him.

Naruto's left eye had an orange ring around it, his right arm had grown several warts. At some point Naruto's body had attained perfect stillness. Jiraiya looked around as well, and he narrowed his eyes.

Nature energy.

Naruto was seeing the nature energy of the planet, only it seemed that it was far easier to make use of than the energy in their world. Even an inexperienced sage would be able to make great use of this. Just by completing the first stage of the stillness training, the ability to see nature energy had been granted to Naruto.

'... He's a Senjutsu Genius... even hsi father took years, and couldn't use it in battle.' Jiraiya had finally found something that Naruto was a natural genius at. Even hard work didn't give you the ability to do what Naruto was doing. He had just wanted to teach Naruto patience, but he did not understand the way this world worked.

Nature was very willing to give access to it's energy to anyone who fulfilled the qualifications to be a Sage it would seem. Naruto had a deep connection to Sage Mode, something that Naruto himself didn't understand. He, Jiraiya, was a Sage and Naruto's own father was a master Sage as well. Naruto's very blood contained an extremely high affinity with senjutsu. The fact this world was willing to give it's energy to Naruto without the boy training was startling.

Jiraiya jumped when he saw Naruto's other eye become red, the pupil changing to a slit.

'It's also drawing out Naruto's negative emotions, which is drawing out the Kyuubi's chakra.'

"Huh?" Naruto asked as he looked in the direction of Kuoh. The constant movements he was making caused his transformation to drop. Naruto seemed confused over something, and he looked straight at Rias for a second. "... She is there... but then..." Naruto had sensed Rias, but he had sensed way more than Rias.

He slapped his cheeks.

He jumped off of the platform he was on, and the second his feet touched the ground, he was gone in a burst of ninja speeds. Jiraiya watched Naruto move with a raised eyebrow.

-In Kuoh-

"Noooo... don't..."

A blond girl had been dragged into an alley, wearing a nun's outfit.

"Don't worry Asia, the pain has only just started. Eventually, it will start to feel good... and then I'll keep hurting you until you break... disgusting nun... but beggers can't be choosers." A blue haired young man in fancy clothes stated as he ripped off her dirt stained clothes, tossing her to the ground as he approached her. He started to unbutton his shirt, a grin on his face that spoke of pain to be inflicted on her even if she didn't resist.

It seemed his plans were for naught.

Raynare had been killed at some point, so his plans to let Raynare kill Asia and bring the girl back to life were a failure. So, he was going to have to go with Plan B, grab the girl and rape her next to a pile of trash. She had to remember that she saved his life, and she would of course remember the fact he was the one at fault for her being kicked out of the church.

"What have I ever... you... you're the devil... I healed... stay away from me." Asia grabbed the nearest thing on the ground she could get her hands on and threw it. Panicked tears starting to gather in her eyes. She was backed up against a wall.

Your hero will arrive soon.

-In Kyoto-

"What the hell... what was that voice?" Yasaka looked at her confused daughter who had heard the same voice as her. It was a voice that came out of nowhere, and she looked at a youkai that was getting up and looking around for the source of the voice.

Yet, there was another youkai that didn't seem to hear the voice at all.

-Somewhere Else-

"Heh... so first that horrifying power... and now nature is talking... and it has such a voice to it... but who is it talking to... and a hero?" A black haired woman, cat ears on top of her head, stood up from where she was. She looked at the sky, a smile coming across her face as she realized that something great had changed.

She spun around on her heel and laughed at the top of her lungs.

This was so amusing, first a power unlike anything she had ever felt before, and now the evils of the world was speaking about a hero. She had thought she had experienced weird stuff before, but she had never even begun to think that something like this would ever happen in her lifetime.

"Nyahahahaha... such a wonderful... monkey boy."

"You heard that too right?" A monkey-like teenager asked her as he jumped down towards her from a golden cloud.

"Of course I heard it."

Dumbass.

Every person with a connection to Senjutsu all across the world had heard that voice, she suspected that the only person who had not heard the voice would be the person it was talking about.

-With Naruto-

He jumped.

Building to building as he sped off, his feet breaking parts of the roof with each landing as he rushed towards the weird thing he had sensed.

'I sensed a girl being attacked by something dark... somewhere around here... but how did I sense that?' Naruto thought as he jumped high up, and even though he couldn't sense anything anymore, he found the spot. He looked and saw a girl on the ground, with a man getting undressed, a gleam in his eyes that Naruto did not like.

He dropped down.

Naruto's feet landed on the man's shoulders, pushing him into the dirt with a surprise attack from above. The fact his pants were around his ankles was all the confirmation that Naruto needed to know that he needed to act now.

Kill him, kill the devil, save the pure hearted.

"Sup... blonde girl, is this guy bothering you?" Naruto asked as he pushed the man's head into the trash, grabbing one of his arms and yanking it up into the air. There was a cracking sound, and screams as he popped the hand's arm out of it's socket.

"You dirty bastard, how dare you get in the way of me attaining my prize! How dare you injure me!?"

"He was... about to rape..."

Naruto pulled a kunai out of his bag and stabbed the man in the back of the head just as the devil underneath him began to charge up to activate magic. He twitched a few times, before he went still as he stayed collapsed on his stomach.

Man with his pants down.
Girl, stripped half-naked.
Guy screaming about her being his prize.
Girl says she was about to be raped.

Naruto didn't need anymore information in order to know that it was time for him to commit a murder then and there. He didn't give his enemy the chance to fight back for even a second once she said what she said, it was as if his body had moved on it's own to deliver justice to the man.

"Your clothes... here... mine will fit you... you should go home." Naruto looked at the sorry state of her outfit. He took off his pants and shirt, before he gave them to her. She looked surprised by the act, just as surprised by the fact he saved her just in time. He started to walk away as she got dressed in his clothes. '... How the hell did I sense her?' Naruto thought to himself, he heard the sound of shuffling clothes.

Naruto jumped on top of the nearest building, before he jumped away with confusion still etched into his face.

"THANK YOU!

Naruto wasn't even paying attention when the girl shouted a thanks to him.

He was just confused about why he sensed her getting attacked.

Chapter End!
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

Senjutsu
1. The reason Naruto unconsciously activated a Semi-Sage Mode was because of the fact that he has a natural affinity for it, thanks to his father being a Sage with years of training before getting Kushina knocked up.
2. In DxD, the world easily allows anyone with an affinity for Senjutsu to have access to it, all Naruto needed to do was sit still and nature did almost all of the work for him.
3. Kurama's hatred is more powerful than the planet's hatred, so nature views Naruto as the hero it wants. Naruto's chakra pretty much she joked nature awake with a punch to the face, and now mother nature has her eyes on him.

Remember.
Even with only 3 clones, Naruto mastered Sage Mode in days, without his clones, it would have taken like a week. That IS what we call a combination of natural genius and high affinity.
