"Don't care about what is going on in the club building, at all?"

Koneko had to ask as she kept her stance low, training her in gym uniform for the most part if you could call it training. She had on a yellow tiger mask with the roman numeral for "4" on the forehead with her eyes and mouth being the only visible parts of her face. She might be in her "gym uniform" but she rolled the shirt up so that her stomach was exposed, and she took off her socks and shoes in favor of going barefoot.

"Not really, Holy Sword hate boner is Kiba's thing, not my thing. Anyway, considering the fact Asia has to heal Xenovia and Irina from what Rider did to them, things are going to be hella awkward in there." Naruto stated as he grabbed Koneko's hands with his own. He forced her to take a knee, before he stepped on her knee and jumped up, kicking her in the chin with his other knee. She went flying, but since he had her hands in his own, she didn't go far before she was forced back into the standing position.

Koneko was interested in doing Lucha with him while the others were talking, since this was her only time she could get Naruto-time without Asia around, she was going to take it. The fact nothing exploded so far was a sign that talks were going good.

"So you know about his Hate Boner?" Koneko pulled her hands back, and she aimed to use her shin to kick Naruto in the crotch.

Illegal move, but still a move that could be used in their training match. She didn't expect it to work though, and it didn't. He shifted so that she kicked him in the shin, and since he was a Rook like her, her enhanced strength and durability meant nothing when met with greater strength and an unknown level of durability.

"Yeah, so you have a lucha mask, but you don't use lucha when you fight. Until now, I've seen nothing but boxing from you." Naruto commented as he sparred lightly with Koneko.

He was not helping her train, he was just having a little fun sparring was all. A light work out to warm him up for his training later. Now that he had a Devil body, all the training he did as a human was finally showing. His growth rate was increasing at a great speed, and he wanted to see just how far he could take his enhanced body.

Koneko grabbed his arm and pulled, so that as she jumped she went behind him and grabbed him. She wrapped her arms around his forehead, and her legs around his waist. She was actually more agile than Naruto was, with his more sturdy build. What he had on her in terms of raw strength and durability, she had more agility than him.

Naruto had more skill though.

Naruto jumped and flipped, and slammed Koneko into the ground before she could finish her hold on him. She let go of him, and when he rolled over her and onto his feet, she hopped up off the ground and turned back around.

"Because, Lucha is a hobby of mine. I like watching gaming videos, and playing video games. Not to mention I love wrestling and lucha, but I'm more suited to boxing. Boxing is the fighting style that lets me take full advantage of my size and strength." Koneko explained as she took a couple of quick steps towards Naruto. She didn't run, or dash, or even move faster than the eye could see, but she focused completely on making her footwork as confusing as possible.

They switched from Lucha to Boxing.

Instead of firm movements, they started to go light on their feet as they raised up the lower stances of lucha. Her switch caused him to switch styles as well.

"I see you're partial to the Basic Guard in boxing, I prefer the Low Hand Guard myself. Since it gets people to attack me, and I prefer to use counterattacks instead of defense." Naruto lured Koneko in and sent a light tapping punch to her ribs. She used her non-punching arm to guard the punch, and she didn't try to step back.

Koneko lowered her stance.

"I can only do the Basic Guard and the Sit Down, my body size is too small to walk people down, so the High Guard is a bad match for me. I haven't practiced with the Philly Shell yet. The Basic Guard and Sit Down allow me to target the opponents center." Koneko didn't aim her blows for Naruto's face, she focused on his chest, or more exactly she aimed at his sternum whenever she thought that she had a chance to attack.

She was on the defensive though.

Naruto and Koneko were standing less than 2 feet away from each other, but their legs were constantly pushing out to test the waters and get a good angle for punchs.

"You're footwork is great though." Naruto offered praise where it was due. "You're no Floyd Mayweather, but your balance is damn near cat-like." Naruto stated as he used the back of his fist to block a punch. He knocked her fist away and tagged her in the cheek with a soft blow. "You favor a firm stance and pivoting, that's a pretty good choice for your body." Naruto analyzed her feet.

Koneko accepted the compliment.

"I'm a Nekomata, or more exactly a super rare breed called a Nekoshou. I was never a human, but my balance and agility are both super high." Koneko made the cat ears underneath her tiger mask wiggle, so that the cat ears of the tiger mask wiggled as well. She brought them out as mostly a test to herself.

She had told Rias that she would work to accept herself, and she was going to follow Naruto's example and better herself.

"That explains the flat chest, cats have very petite and lean bodies, except for tigers most female cats are all petite for their size." Naruto taunted Koneko very lightly. They both exchanged a constant, but slow and testing, barrage of punches. Both of them were just seeing which person would open a hole in their guard first.

Koneko tried to think of a taunt.

"I'm surprised you can get balanced at all with that cock you have, Mister Monster." Koneko ended up with a semi-compliment, but she knew that he was a little self-conscious about his own size in that he felt like he was a bit too big. They were sparring though, so a little bit of trash talk here and there was all in good fun. "Anyway, my sister is a titty monster, just a little smaller than buchou, your preferences?" Koneko asked Naruto.

She had the potential to get big boobs, or at the very least bigger than what she had now. Devils had a limited amount of control over how their bodies would grow, from ages 15 to 17 was when they really got their growth spurts in sexual trait sizes.

"Ass man, no tit preference, toned thighs are my biggest preference though." Naruto didn't comment on the casual reveal that she had a sister.

Koneko raised an eyebrow.

"I was very uncomfortable revealing my sister to you... you know she is a super criminal, right? You could offer a greater reaction." Koneko had her closest blow blocked by an elbow. The blow that would have got the center of his chest was blocked.

She was using this spar as her chance to glow closer to him.

"Your species and criminal sister don't matter to me, either way Koneko is Koneko. I'm going to judge you on your actions. You train harder than anyone else in Rias' peerage, and it shows. Kiba and Akeno might be stronger when it comes to combat power, but I would rather have a hard worker than a genius as a friend any day of the week." Naruto casually admitted that he didn't care about her past situations. He didn't care what species she was, as a general rule, the only species he was slightly against was Fallen Angels because of his own personal bad experiences.

Even then, he was only slightly wary and didn't actually hate them.

All species would one day be members of his Kingdom.

"You know I'm in love with you, right?" Koneko asked him.

A casual love confession.

"With how you and Ravel started to bicker, I already knew. I'm dense, but not blind. I might not understand a woman's heart, but when you girls shout your feelings out and fight over me, even I can understand that." Naruto wasn't some blindly dense harem protagonist. He was dense towards a girl's subtle emotions, but there was no way that he could not notice when a girl was practically throwing herself at him.

Koneko tossed another fist at his chest, but she was smiling that he had already noticed her feelings.

"So, what are you going to do about them?" Koneko asked him as she took another soft blow to the right breast.

"Give you an honest chance, just because you love me, doesn't mean I HAVE to love you back. So I'm going to give you an honest chance to get me to fall for you." Naruto stated his intentions. They continued to box each other the entire time they had the normal conversation, Koneko scored a light tap on Naruto's arm that he didn't block. 'She changed targets from the sternum to the arm, good for her though.' Naruto blocked three harder and faster punches though as she upped her game.

She was using her agility even more, and was adding dodges to what she was doing instead of just blocking. Her feet never left the ground as she shifted them, and moved only her upper body as she dodged.

She spun and kicked.

Naruto thrust his foot forward, and jabbed her in the stomach, pushing her back out of her leg's striking distance as she continued her spin and landed in her boxing stance. She looked at the way that Naruto was standing.

"Muay Thai, different than Boxing." Koneko noted.

She didn't know Muay Thai, so she kept her boxing stance and shifted forwards towards him.

"My Boxing style doesn't have defenses, and focuses on counters. That is why for defense I can switch into Defensive Disruption Muay Thai style attacks. I use Boxing for offense, Muay Thai for defense, Lucha for agility, Sumo for grapples, and I mix Krav Maga into all aspects of my combat to enhance them." Naruto explained to her as he raised his fists up, his index and middle fingers slightly extended from away from the rest of his fingers.

Koneko pushed forward with more energy.

"Using so many martial arts together, it must be hard to master all of them." Koneko gestured as she leaned back and ducked a fist that swiped in front of her nose.

Naruto and Koneko made brief eye contact for a moment as their forearms pushed up together.

"I actually try to avoid 'Mastering' any one fighting style. Muscle memory is a thing, and mastering one thing makes it harder to completely master another. So instead, I pick and chose which parts of a Martial art to Master. When I said I use Muay Thai for defense, I also use a couple of Defensive Boxing techniques and mix those into them as well." Naruto mentioned as he went back to boxing.

Mastering a single "Martial Art" didn't make you unbeatable in that martial art, so in his eyes, there was no point in pushing any one martial art to the point of pure mastery. Those that had similar levels of mastery would know all the same techniques as you, and would know counter techniques. Mastering a single martial art only gave you weaknesses, it was fighting a clone of himself that used Boxing that showed him that.

So, he pushed each martial art to the point of "Almost" Mastering them, so his body could still easily learn and combine what he knew, with what he was learning.

His body didn't have a "Default" setting for martial arts, because his muscle memory didn't default at a certain style. His muscle memory was at the perfect point that he could constantly add new elements to his martial arts.

"So, instead of having a Black belt in one martial art, you have 5 blue belts across multiple styles. You fight with more skill than a black belt BECAUSE you never mastered a single art. That's pretty cool, but I'll stick to mastering Lucha and Boxing." Koneko exchanged another blow with Naruto. Their blows were getting more fierce with each other as Koneko started to have more trouble keeping up with his style.

She could keep up with he stuck with either pure Lucha or pure Boxing, but the second he started to change and mix together styles, she stopped being able to predict what he was going to do. Each reaction she had, all of her defenses, relied 100% on her senses being able to react to his movements. She gave up trying to predict what he was going to do, and stopped looking at his muscles for a hint of what was to come.

"Kind of like that, I call it-"

"Total Package Martial Arts." Koneko helpfully supplied a nickname for the style.

It was a Martial Arts that used the most useful elements of different styles, and mixed them together to create a style that surpassed the originals.

"Oh hah hah, Total Package Uzumaki, using Total Package Martial Arts, oh how original." Naruto rolled his eyes to her taunt.

...

"I mean, isn't it."

"It is original, and it's a good joke, admittedly." Naruto relented that what she said was actually a pretty funny joke, and it made complete sense to call the martial arts that. "Not using it though." Naruto added.

"Suck it, I'm calling it that."

"Don't make me punch you."

"Do it, I dare-"

Naruto punched Koneko in the face by getting inside of her guard, and knocking her to the ground. Naruto grabbed her leg while it was still in the air and rolled on top of her. Naruto forced Koneko to do the splits with one arm and his legs, before he grabbed her other arm and forced it behind her back, pushing it against her own butt. She only had one arm to use, but she wasn't able to use it to attack or reach him as her face was rubbed into the dirt.

"Don't dare me, we're sparring, I'm actually going to punch you." Naruto stated to her.

"Kiss me, I dare you."

"Nice try, that was a nice spar... and it looks like... what the hell happened?" Naruto asked when he saw Issei and Kiba storming out of the club building with pissed off looks on their faces. Behind them were Xenovia and Irina, ready for a fight as well with Asia, Akeno, and Rias following behind with annoyed looks, but Asia was showing concern.

"Long story short, Xenovia asked Asia if she wanted her to kill her, and that started a conflict... though the Knight was itching for a fight from the start. Seems the blue haired girl, Xenovia, was demanding to talk with you as well about a Devil using a Holy sword... her Holy Sword." Ravel explained to Naruto, seeing his confused face, while she walked out of the building last. She raised an eyebrow when she saw the position Naruto was holding Koneko in. "... What is with the Masks and that pose."

"He's spreading my legs and working up a sweat with me, because I know how to please a man." Koneko stated.

...

"We were sparring... and I'm sorry, bitch said what to Asia?" Naruto let go of Koneko and stood up, cracking his knuckles as he stared at Xenovia. She was too focused on Kiba and Issei to pay attention to him.

He was pretty sure he was going to have to punish Xenovia for that.

"You're going to punch her."

"She threatened Asia, that means she gets a fisting." Naruto cracked his other knuckles.

Xenovia better hope Issei and Kiba took her down, because if they didn't, then he was going to be the next opponent for her to face.

It was fisting time.
