Story Start!

There were spies in Grigori.

Usually spies waited until they had important information to break their cover, and the information that a boy had learned Boosted Gear, Divine Dividing, and another Sacred Gear was news enough to risk reporting back to superiors ahead of time. Even if there was NOT a spy, it was hard for the group to not have the selfish few who would sell the information to the other factions, and have the news spread from there.

The news had already been spreading like fire among Devils due to gossip with the Sitri and Gremory maids.

It was pretty much an open secret at this point that was becoming common, and terrifying, knowledge that some boy named Uzumaki Naruto was learning how to use Sacred Gears. That was ALL that was known about him to those without personal accounts, but that was all that was needed for factions to decide to take action.

This boy needed to be killed.

Before his power grew to be too much to handle, he needed to be ended before he could become a threat even bigger than the greatest threats. If he were to learn other Sacred Gears of even greater power than Boosted Gear and Divine Dividing, not even the strongest of the Longinus level Sacred Gears, then the fact he could combine their abilities together would be enough to make godly beings crap their collective pants.

Assassins.

Well, to be fair, at the moment only those with a reason to be afraid were bothering to send assassins after Naruto. Those who knew that they needed to be fearful of him growing more strength.

Heaven, since Naruto had started to date a Devil.
Yokai, since humans and yokai didn't have great relationships.
Hades (both the person and the place), because a human shouldn't be gaining that much power.

"You're fine with just... this?" Sona asked as she walked with Naruto, hand in hand, through the park in the middle of the night. She had suggested that they deepen their relationship with physical intimacy, after all this man was to be her future husband. The sooner she could get herself pregnant with his child, the better things would go for cementing her place as his one and only. "Just hand holding?" Sona asked him.

That was suspiciously non-perverted.

"It's how relationships start, walks through the park, hand holding, then kissing and movie dates, getting to know each other better, then take things from there. I want to do things the right way, and show off my good aspects to you. I'm going to capture your heart." Naruto stated as he grinned at her.

She adjusted her glasses and sighed.

"That is unneeded, I already plan to make you my husband one day, love can come later. I think that we should check our sexual compatibility." Sona argued against his naive notion of taking things slow. "You do realize in this modern world, there are many girls who will put out after just meeting the guy once." Sona reminded Naruto of the sad facts of the decay of modern society.

Naruto huffed.

"Well, I don't want those girls, I want you." Naruto crossed his arms in front of his chest.

"I'm literally a Devil who turns men to sin, in my culture, that is 99% of how females work, including myself." Sona reminded him. She was programmed mentally to turn humans like him into sinful beasts who wore their lust and other sinful feelings on their sleeves. "You ravaging my body would be a sign of pride I could bring home to my parents." Sona stated to him.

He kept his arms crossed.

"Well, I don't like... ah, assassins." Naruto stated as he looked around.

"Assassins?"

"Oh, I didn't tell you, when I went to Konoha High, a group of assassins were after my life. They haven't attacked me in a few weeks though, but I've got a sixth sense for people targetting an intent to kill." Naruto stated with a grin. "You feel the urge to kill directed at you enough, and you learn to sense it." Naruto stated.

He pointed to 2 locations.

"... I see..." Sona stated as she got ready for battle.

"Come on out Akatsuki, lets get this started. You did you send this time, is it Kisame or Itachi... maybe Sasori?" Naruto asked as he took his jacket off and tossed it to the ground.

3 people jumped out of the shadows.

A nun.
A grim reaper.
A cat girl.

"To be fair... I was ASKED to kill you, and if I'm not satisfied I will do that... but I'm just here for a favor." The cat girl, who Sona recognized as the SS-class criminal Kuroka, stated as she landed on the branch of a tree in the park. "By the way, I'm also not in alliance with these two." Kuroka corrected the idea that this was a team up.

This was a coincidence.

"That's... Griselda Quarta, one of the Top 5 women in the Church... and..." Sona didn't know who the Grim Reaper loli was. She knew of Kuroka and Griselda, and that was about it for who she was aware of.

"I was ordered by Hades to kill you and steal your soul."

"Ah..." Naruto realized why he sensed only 2 sources of killing intent, because this girl didn't want to do her job. She was being ordered to do something she found distasteful, so her heart just was not in it. "Do you want to just get out of here, leave the job to these two?" Naruto asked the Grim Reaper girl.

"Oh, you seem pretty confident." Kuroka stated as she got ready for battle.

Griselda wordlessly pulled out a bow with a string made out of light, and she prepared some artificial light arrows. She was prepared to kill without introducing herself or speaking with the young man in front of her at all.

"Sitri devil, leave."

That was all she said.

"Okay then... so you're a bow and arrow user, and you're using a bow that uses arrows-" Naruto was interrupted when Griselda started the fight by unleashing 3 arrows at him. Sona used her water magic to create a water serpant to take the arrows. "... Sona, I've got this." Naruto stated to her.

"Leave this area at once, you have no authority here." Sona couldn't force Kuroka to leave, but she could issue threats.

Threats with no power behind them.

"-you use a scythe, and I'm guessing death themed stuff... high magical power... okay then. I know what I'm going to do... Give me your best shot. I'll defeat all of you together or apart from each other." Naruto stated with a proud smile as he crossed his arms. "Sona, don't interfere. That's powered by light right?"

Griselda had her eyes widened forcefully when Naruto held his hands in front of himself and created a Bow of Light using pure light magic. Naruto grinned as he got the concept of what she was doing by feeling her out.

'Still, he shouldn't be a match for me and my experienc-' Griselda should have expected a surprise, but they sent her for a reason. She saw the Grim Reaper girl appear behind Naruto with her scythe already in mid swing.

Kuroka was next to Naruto with a magic blue flame in her hand.

"Ah! You're connected to nature, aren't you! What is that called, and how do you do it!?" Naruto asked as he vanished into the ground and came out of the ground 10 feet away. It was like he just sank in the earth like it was water.

Bennia, the Grim Reaper, jumped over Kuroka as to not hit her with her scythe, but Naruto rushed towards her and stepped off of Kuroka's shoulder. He wrapped both of his hands around Bennia's neck and held her upside down in the air facing away from him, before throwing her back first into the ground.

Kuroka grinned.

Naruto blocked 3 arrows aimed at him with 3 of his own arrows, destroying them completely.

'No, he already has a mastery of the bow! He just learned how to use light magic!' Griselda went on the run as she took aim at Naruto's head while he was in the air. Kuroka jumped into the air, and she threw several magical orbs at Naruto.

Naruto created a barrier of wind magic around one of the magical orbs and kept it from exploding, while the other orbs destroyed parts of the park around him.

Bennia was slowly standing up after having the wind knocked out of her, and her neck squeezed hard enough to make breathing uncomfortable. Naruto's blow was meant to keep her from fighting for a moment, but not hurt her too badly.

"How can you tell?" Kuroka created several illusions of herself around her.

"Well, I used an ability I learned to give energy to a tree, and your energy just now felt like it had some trees around here in it. You're drawing power from nature... AH... I think I get it!" Naruto looked around at the illusions, each of which had magical power to make it work and thus hard to tell from the original.

Griselda took a hiding spot up in a tree and aimed at him.

'If he sees me, he can copy me... I need to remain out of sight, and now show him how my tricks work. His learning ability is insanely problematic.' Griselda wanted to make sure that her next shot would end things if all possible. She wasn't teaming up with Kuroka or the reaper, but if they wanted to make her job easier, then she would accept that as part of how things went.

Bennia appeared behind Naruto in mid swing.

She jumped back when a scythe came out of the air and landed between her and Naruto, and Naruto just reached behind himself and grabbed it.

"So, a Scythe user, a magic user, and a bow user." Naruto was holding Kuroka's attack with one of his hands controlling the magic, and he grasped the scythe with his other hand. He tossed the bow he created in the air and it floated above his head. "Light magic seems the opposite of demonic magic, so it wasn't too hard to figure it out... but I need to control my output better. I'm wasting some magic." Naruto could feel that he was wasting some magic with each arrow he fired.

A dozen arrows fired all over the park and pierced each of Kuroka's illusion clones, revealing that she was not among any of them.

Poison mist started to fill the area around the ground.

"You... NO, that isn't fair! You already negated my poison NYA!?" Kuroka shouted in shock when she saw Naruto completely unaffected by the poison.

"Poison is simple, the easiest thing in the world. Poisons are just things that, when absorbed into the body, disrupt body functions. So, to negate them you just need to make it so your body can't absorb them." Naruto stated as he went scythe to scythe with Bennia, but she was a speedy loli, and kept vanishing right after they clashed.

Kuroka purred in distaste.

"... That's how poison works?"

"Yeah, I just invented a spell to prevent my body from being capable of absorbing poison." Naruto answered Bennia's question when she asked how poison works. Naruto kept glancing at the magical energy in his hand that he was keeping from exploding.

Kuroka flew into the air and prepared to rain down magical power on both of them.

Dozens of her explosive flames appeared around her.

'Why is he keeping that magic attack in his hand still?' Kuroka thought as she saw an arrow fly out of a tree and head straight towards Naruto. She unleashed her magical attacks down in unison with the arrow. 'Why is he only using a Scythe, Bow, and Magic... can't he do more than that?' Kuroka thought when she noticed something off.

Naruto grabbed Bennia by the waist and jumped out of the way of the arrow AND the magical attacks, using strategic bursts of wind to escape each blast by a hair's breath.

It looked like Naruto was analzying how her attack worked or something.

Why though?

"No... THAT'S BULLSHIT! It took me years!" Kuroka was PISSED when she felt Naruto start to absorb energy from the nature around them. It took her years of hard work to be able to do what he was doing now, in the middle of combat. She watched as Naruto's eyes gained a glow to them, and red rings appeared over the tops of his eyes. She sensed it before saw it, but that didn't stop her from being pissed. "HOW!?" Kuroka landed on the ground, on all fours.

Naruto let go of Bennia.

"Of course I'm going to figure out when you keep showing me how you're drawing power from nature."

"I didn't show you SHIT boy!"

"Of course, you kept using magic against me. I just needed to pay attention to your magic, and I sensed how you were doing your trick. I still don't know what abilities I gained from doing this though... something to think about later, unless you want to teach me the tricks of this form?" Naruto asked with a grin. "... Ah... that's a lot of anger... hey, 2 or 3 of you guys focus on stopping that will you?" Naruto tapped the side of his head, no longer needing to analyze Kuroka's magic and throwing it back at her.

When he used this new form, he felt a nature try to corrupt him with anger and power drunkness, he would transfer that feeling to one of his other minds though. They could deal with the side effects.

Bennia backed off when he let go of her.

'He saved me?' She questioned with a tilted head.

'He's learned Senjutsu in JUST the amount of time I've been fighting him... just because he analyzed my magic and watched me do it... this guy is a complete freak of nature... He's negated my poison, illusions won't work... time to punch.' Kuroka stated as she took a deep breath.

She rushed at Naruto.

The space between herself and Naruto shrank more than she expected, when Naruto used Senjutsu to create a barrier between them. The barrier teleporting things that entered the barrier to the other side of the barrier. He used the spacial manipulation ability to create a barrier, as an OFFENSIVE attack!

Kuroka was punched in the face as an arrow pierced her back.

'What!?' Griselda thought when her arrow pierced Kuroka instead of Naruto.

Naruto created a barrier that intercepted her attack, and teleported it behind Kuroka instead. He was using the defensive skills of Senjutsu and turning them into offensive skills. Griselda's eyes widened when an arrow was shot out of the floating bow above Naruto and aimed right at her. She dropped from the tree she was hiding in before it could hit her.

"Bitch, why did you shoot ME NYAN!?"

Naruto performed a combo on Kuroka, tossing her up a few feet off her feet, before he grabbed her by the throat and brought her to face level, and slammed their foreheads together.

'He switched from magic to physical combat the second I did...' Kuroka realized after a moment.

He wanted to beat them at whatever they used to attack him with, when she used Senjutsu, he used Senjutsu. When she used magic, HE used magic. When the nun used a bow and arrows, Naruto used bows and arrows. He wasn't using his learned Sacred Gear abilities, because none of them were using those abilities.

To him, he just wanted to learn what they were doing against him, and become better than them at it.

'I was right, once he sees something, he starts to think about how he can use it for himself, and master it in ways that the original user didn't think of.' Griselda took a standard light sword from her waist and charged at Naruto. While he was savaging Kuroka with his forehead, both of his hands were full.

She would take his head off his shoulders from behind.

"Duuuuuuh?" Kuroka had blood covering her entire face from where he smashed her forehead close to 20 times against his own forehead. He had split her forehead open at the skin, and no doubt cracked the bone. "I don't want to do this anymore..." Kuroka muttered, as she felt him smash their heads together again.

She should NOT have accepted this request.

"Okay, then OFF you go!" Naruto slammed Kuroka into Griselda when she got within striking distance, swinging Kuroka as if SHE was a sword.

Sona was just watching this with a sigh.

'The more of their abilities they show him, the stronger he becomes... not just that, but he has so much imagination that he uses their abilities in ways they couldn't dream of doing. The more you fight him, the stronger he gets... the more he trains... the stronger he gets... if you give him a goal, he masters it in record time the second he puts his mind to it.' Sona watched as Naruto picked up Kuroka and tossed her over his shoulder, while Griselda was bleeding from the side of the head.

Naruto had smashed the women's heads together hard enough to knock both of them out, more so Kuroka who might have brain damage from her forehead beating.

"... I surrender." Bennia stated as she raised both of her hands.

"Okay!"

Bennia figured out she had no chance of winning at this point.

"Okay then, since my house doesn't have anymore maids thanks to Sona here. I'm claiming ownership of this cat... AND you." Naruto pointed to Bennia with a grin on his face. "... Can't claim ownership over her though... since she is human." Naruto stated as he looked at Griselda.

Sona didn't argue.

"Kuroka is an SS-class criminal."

"That means absolutely nothing to me, she came to take my life, so I'm taking her life... as my maid. The same with you." Naruto spoke to Bennia after Sona.

She nodded.

"That seems fair."

"They are going to kill you in your sleep." Sona added, and Naruto wrapped his hand around Kuroka's neck. Then he touched his hand to his heart, and Sona saw a spiral mark appear underneath his clothes, a mark that glowed for a brief moment.

"I die, she dies... she dies... nothing happens to me. Reaper loli, your turn." Naruto reached out and grabbed her by the throat.

She didn't exactly resist.

"When did you learn this?" Sona asked that simple question.

"I learned it from your Evil Pieces, that bind a person to their master. Well, I just used the same process to bind their lives to my life. I die, they die, as long as they are alive, I share their lifespan." Naruto laughed at his brilliant idea.

Sona thought about that.

"... So..."

"I now share the same lifespan as whichever of these two girls is going to live longer! See Sona, now you don't have to worry about my lifespan being short!" Naruto laughed at the stunned look on her face.

Sona palmed he face.

'This idiot is just painting a bigger target on his back.'

The target just kept getting bigger.
