*BOOM*

"You see what I'm doing wrong, because I don't know why it doesn't work."

Naruto had never had a sparring buddy before, so he wasn't sure how it was suppose to go. He and Moka had finished their sparring 15 minutes previously, since it wasn't a true fight, they just continued to spar until one of them landed first blood on the other. No winners or losers, but healthy sparring to the not-death.

Naruto showed Moka a technique that he had been working on.

"Hmmm, this technique is... familiar to me, but I don't recall why. Either way, can I see you do it again?" Moka asked Naruto with an analytical look on her face. She was happy he was showing her a technique, but if he made up the technique or copied it, she was unsure. She just knew that she had seen a similar technique to it used before.

All she saw was Naruto use his hand like a sword and cut down a tree.

She saw Naruto frown, before he looked down at his right hand, and he flexed it a couple of times. Naruto walked over towards a large boulder that stood in front of a tombstone, one of the many tombstones that littered the school grounds. Students died at the school quite frequently over the years it would seem.

"I don't know what it's called... but I remember getting hit by it, and I memorized what it felt like. Something feels like I'm doing it wrong though." Naruto stated as he flatted his hand into a sword, and swung it. The boulder exploded, but at the same time, instead of going flying into chunks, it exploded into a perfectly cut boulder. A perfect cut the length of Naruto's arm going down the center of it.

Moka frowned.

"No, you're using whatever that is correctly. Why do you think you're using it wrong... are you okay?" Moka asked as she crossed her arms and walked over to him, his right arm going dead limp at his side. Naruto winced in pain, but he flexed his arm and forced it to move again. Now his arm was visibly shaking from the effort it was taking to move his arm. "That technique, it has a harsh recoil on you doesn't it?" Moka could understand why.

He was doing something amazing.

Naruto was using Yojutsu, monster arts that relied on Yoki, the spirit energy of monsters. Instead, he was human and he had no yoki at all. Vampires could sense yoki easily, and she could sense none of that energy in his body at all. He was a pure human, who had somehow managed to convert his own life force into a bastardized yoki all through sheer effort and willpower alone.

"Yeah, it does... but it hurts less than when I was hit with it. Still, I can only use it for .5 seconds before my hand is useless for awhile. So I've got to be doing something wrong, since the person who hit me with it could use it constantly." Naruto stated with a grin on his face. He looked at the tree and boulder he cut in half, his hand having phased through them like a knife through butter. He hadn't even felt them as he cut through them, and he couldn't even begin to explain how he had done it.

When he had been hit by the technique, it had been like Aqua's hand had both been there and not been there at the same time. So he tried to copy that, and he had a clear mental picture of it, so he forced his body to do it and copy the same feeling that Aqua's hand had left in his chest.

'So that's why he didn't use it in our fight, for one he wasn't trying to kill me, and two he can use it twice before his hand is unable to fight. It's like an unstoppable sword, but it's double-edged.' Moka analyzed the technique's nature, and she looked at Naruto without hatred for him holding back in there fight.

You should never use your strongest technique against a powerful opponent, when the drawbacks could leave you helpless. Not when you wouldn't know if the opponent could dodge or counter those techniques. It was the height of foolishness, but still, the fact he could use it twice at all... no even once at all was amazing.

This Human was a real Monster down to his very soul.

"I've got to figure out what I'm doing wrong."

"You're not doing anything wrong, you've got the technique down. Factually speaking, you shouldn't even be able to do this at all. It goes against the laws of nature."

"Fuck the laws of nature, nobody can tell me what I can't do, not even my own body." Naruto stated with a challenging grin to himself. "Anyway, when I try to use the technique more than that, this happens." Naruto stated as he raised his hand up.

Moka was splattered by blood, it getting on her face.

The blood vessels in Naruto's arm popped as blood gushed out of random spots, and his bones visibly broke under the stress. Still, Naruto swung his arm and sliced through another tree easily enough, the technique still worked.

"The first time you use it, it weakens your arm. The second time you use it, the power inside of your arm swells up too much, and gathers stress. The third time though, all that stress and power is released at once and destroys parts of your arm." Moka realized as she used her finger to wipe his blood off of her cheek. Naruto wasn't looking at her, so she licked it off of her finger.

Moka blinked.

His blood was absolutely delicious.

Strong flavored, powerful, so full of rich vitality and life that the full bodied flavour just popped and exploded across her tongue. It was sweet and spicy, but it was also savory as well. It was strong and healthy, the blood of a man who kept his body in pristine condition, but it didn't lack the fun flavors of salt and junkfood either. It was less metalic than usual blood, but the metalic flavor only added to the stronger flavors, making one even more appreciate the unique flavor of the blood.

Tsukune had great blood.

Naruto had blood was divine in comparison, there was no contest who was the alpha male going by blood taste alone. Naruto, who had a trained to perfection body, had blood that was honed to such the same degree.

"When I first used it, my arm would explode the second time... but even after 9 months of training, I've only raised my usage of it by one time." Naruto frowned deeply at his own lack of improvement.

There was a reason he couldn't use it in battle.

Moka was shaken from her food bliss.

"We-well..." Moka didn't stutter, she never stuttered even when she was embarrassed at having become euphoric over blood. "You did say your limit was .5 seconds." Moka gave him some credit.

Naruto only frowned.

"It is, and it was when I first used it. I haven't gotten stronger with the technique, I just wait until the last possible moment to unleash the technique. The moment before it hits, and I release it the moment it passes through the object." Naruto hated his own weakness.

He should have mastered this by now.

Moka didn't say anything.

'No, you have mastered the technique... the fact you've mastered such an insanely advanced Yojutsu after only having experienced it once is frankly amazing. You've ignored your own biology as a human and mastered it, it's your human body that is holding you back.' Moka could feel nothing but pity as she saw a man training in a technique he shouldn't be able to master, master the technique, but be unable to use it to it's full potential because his body limited him from it.

Simple explaination.
If Naruto wasn't human, he would have mastered this technique to such a level that he could use it nonstop with no weakness and no drawbacks. Because he was a human with no yoki though, the fact he was using the technique without yoki was already breaking the limits of what was possible. The drawbacks on his human body were too intense.

If he weren't human though.

-Another location-

"... and the day will come, when I see him again... when his potential is at it's peak. Then, I'll finally be reunited with my Naruto-kun and turn him into the monster he deserves to be. I'll give him as much of my blood as it takes to turn him into a Vampire..." Aqua said as she spoke to herself, a dastardly grin on her face. She looked at her arm, where she had a scar that she refused to heal.

The only scar on her entire body.

The scar inflicted on her by Naruto, who despite being human, had been able to draw in combat with her. Not only did he draw against her, but he as a human had gotten a grasp of how yojutsu worked and even used her own technique against her without even realizing it. She didn't even know if he realized what he had done, but he had scarred her arm all the same by using her technique on her... but with even more power than her own technique.

She could see why Naruto had been slatted for assassination.

2 years previously, she had been asked to assassinate a human who she had been told was growing too powerful for a human. The rumors stated that the human body had defeated a group of monsters, in their human forms, and beaten them to the point they were sent to the hospital. A pure human with that power was scary for many monsters, since humans were only able to kill monsters with the use of weapons. A human who could kill them with just his fists alone could change the entire status quo for them all.

"You, a human who didn't even know monsters existed... you battled me, a powerful Vampire, to a stalemate. A 13 year old boy was able to give me a fight that even most Vampires couldn't give me. You deserve to be a Vampire far more than the usual Vampire born with that power." Aqua couldn't wait to see how much he had improved, how strong he had gotten. His potential had been something too great for her to ignore or waste by assassinating.

Not when that strength was so beautiful to her.

He was like the sun itself, and when she had tasted his blood on her fingertips, she had fallen in love with it. His blood was just divine, the blood of somebody who experienced true sorrow, had nothing in the world. The blood of a boy who was able to love others, despite not having a family, not having friends, having nobody in the world to call his own. His blood, his body, his power, and his heart were all beautiful and stunning.

He was the sun, and she was the moon.

"You're mine Naruto-kun, mine and mine alone. Nobody in this world could ever truly experience all you have to offer. I always thought that I only loved my darling sister Moka, but you've proven me wrong... you are the only man I awknowledge... so grow stronger for me, and me alone." Aqua shivered as she thought about what she could experience in the future.

Her next fight with Naruto, she could hardly wait for it, but she needed to be patient.

She so wanted to fight him though, to fight him and make him bleed. She wanted to beat him into a bloody pulp, and she wanted to be beaten to a bloody pulp by him. She didn't want to stop fighting until so much of their blood was splattered across the ground, to the point where she couldn't tell where her blood stopped, and his blood began. Their scents mingling together in a beautiful harmony.

Of course, she wasn't going to play fair.

Once the two of them were too beaten to move, she would have her sister take her and kidnap Naruto, so that she could recover enough of her blood in order to transfer it into Naruto's body. In his weakened state, the transformation would be a simple matter, and it wasn't like Naruto's willpower was so weak as to allow himself to become a ghoul.

-With Naruto-

"Well Naruto, sorry to say this, but we have school tomorrow so lets cut our sparring here. Maybe next time, we can have a lunch together as well. We shouldn't spar on an empty stomach." Moka slyly asked for another sparring session, only next time she would like to have a more... romantic little lunch. She had never cooked before in her life, but Outer Moka did it all the time, so she was sure that she could do it.

She felt a spike of yoki, and she looked over to see Mizore hiding behind a bush, glaring death at her but too afraid of her to try and attack her directly.

Well, she could deal with Naruto's stalker when she felt like it.

After all, it was only one stalker, how many could he have?

Somewhere in the world, Aqua sneezed.
