Free as a bird, in love with a cat

He was Rias' twin brother that disappeared into the world in order to gain what he couldn't in the Underworld. More than half a decade later he returned to help her and others with the current situations that have appeared surrounding Kuoh

~Chapter 15~

Naruto wore a small smile as he watched Issei's process. It had been a week and already there was a visible improvement after just a few days. His speed had noticeably gone up after Le Fay had made him along with Rias' peerage weight seals. Now he actually had to put effort when sparring. It wasn't a whole lot but for just two weeks it was impressive. His strength and muscle mass had increased slightly as well. Where before he could barely do a few push ups now he was blazing through the standard routine he had set up for him.

Not too far away from them were Rias along with Akeno, Asia and Koneko. They had finished up another spar earlier with Kuroka who was sprawled out in the grass just a couple of feet away from them. They too were impressed with how quick Issei had improved. Rias and Akeno could sense the increase in magic reserves he had which everyone including Issei were happy with.

Ouch Rias winced as she saw her brother slam her Pawn into the ground. She noticed naruto had gotten more aggressive when sparring with Issei. She had to hold herself back not to run up to them and check him over. But she couldn't, the beatdown Naruto was delivering Issei would do him good and make sure he won't become arrogant later while making him capable of enduring more.

That wasn't the only noticeable change Issei underwent. Much to her -and the rest of the school's- surprise Issei actually managed to tone down his perverseness. It was shocking really for everyone to see Issei decline an opportunity to peep on girls. However, she could see that Issei was quite pleased with her brother's stipulation that he would have to stop being a pervert if he wanted Naruto to train him. She had already heard whispers go around that Issei changed due to him hanging out with them. Not to mention that he gained popularity once they noticed he stopped hanging around with the other perverts.

Now that she thought about it, it wasn't that Issei was unpopular because he wasn't likeable it was just that he was a perverts who most thought only attended the school in hopes of getting some.

''Come on Issei, stand!'' Naruto commanded to the gasping boy on the ground. Groaning Issei managed to get back on his feet, his legs wobbly as he got into a stance.

''Alright that's enough. I can see you can barely stand and it would do no good for me to permanently injure you.'' Naruto said with his hand lifted.

Issei however stubbornly refused. ''I-I can still fight sempai.'' He said between deep breaths.

Naruto shook his head as he saw this. He had learned that Issei was very stubborn over the last few days when it came to giving up. Hell, it seemed like he wouldn't stay down unless he knocked him out. So with that in mind he allowed Issei to attack him. Wincing slightly as he approached him Issei lashed out only for Naruto to catch his outstretched hand and once more tossing him on the ground.

''Rias!'' The sound of her brother calling out to her snapped her out of her thoughts.

''Huh?''

Naruto pointed down. ''How about you get him up. Don't worry as he's still conscious.'' She looked and saw Issei laying flat on his back and nodded back at him. She stood up with her peerage following her example as they walked over to Issei, passing Naruto who was heading towards Kuroka.

''Comfortable?'' He asked her as he stood over her. Kuroka moved her eyes towards him, squinting slightly as the sun shone behind him.

''Yup.'' Was her answer as she nodded with a smirk.

Naruto shook his head before motioning her to stand. ''Come on, the others are heading inside.'' In response Kuroka held her arms out towards him like a child. ''Really…'' He asked with an eyebrow raised. Instead of answering Kuroka pouted and made grabbing motions with her hands. Sighing he ran a hand through his hair before kneeling and lifting her up in bridal carry. Kuroka gave a victorious smile and leaned into him as he carried her inside where the others went.

Entering their house Naruto spotted the group with Issei resting on one of the couches and sat down near them with Kuroka still on his lap. ''Hey Rias, have you heard anything back from our brother or Sona?''

Rias gave him a confused look before her eyes widened slightly as she understood what he meant and shook her head. ''No i haven't. He said he would look out for it especially since we know the reason they are here for. What about you? You know that earlier confrontation you had with those two.''

''Huh?'' He asked while doing his best to ignore Kuroka who was moving in his lap. ''Oh you mean that.. Well i'm not really sure. I mean they were looking at me expectantly like i was supposed to know them or something.'' He said recalling what happened a few days ago. School had ended and he along with Kuroka were making their way outside class only to bump into the black haired boy, Sasuke. A small staring contest was the result till Kuroka had snapped him out of it. He could see it in his eyes that he was looking at him as if trying to find something. Not to mention he could feel both his and the blond, Menma's eyes on them as they walked away.

It didn't stop then as he could swear he saw them along with the girl, Sakura purposely running into him, especially since the placed he ran into them were quite obscure when not inside. It was somewhat worrying as Koneko had earlier discovered that they were apparently looking for someone.

He knew they would start something however. At least as long as the black haired boy was around as he seemed the calmest of the three while the blonde gave off a weird vibe. Like he was restraining himself from something. He had felt in the brief times they met the boy almost glaring at him but shook it off as nothing too important at the time.

''Yasaka also hasn't found anything about this 'Konoha' they are from so for now i guess we keep our guard up just incase.'' He said as they all nodded. Despite the school holding over three High-Class Devils with two Maou's as siblings you could never be sure who or what was stupid enough to attack them.

''Anyway, have you all gotten used to those weight seals Le Fay placed on you? If so let me know so she can add more to it as you're all still quite slow.'' He said to them. ''Speaking of training, the next couple of days i'll be working with Rias while Issei will spar with Kuroka. I want to see how good she exactly is with the power we have.'' He looked at her and saw her nodding.

''Is that fine with you as well?'' He glanced down to Kuroka who was cuddled up into him.

Kuroka nodded her head though whether it was because she heard him or not was unknown as it seemed like she was about to fall asleep any moment now. Naruto released a sigh as Kuroka's head began to droop and gave Rias and her group an apologetic smile. ''We're done for today. I'll see what i'm going to do with Kuroka here and you can do your own thing.'' His sister's peerage stood up. ''See you all tomorrow.'' He waved at them. Carefully as to not bother the sleeping Nekomata on his lap as one by one they activated teleportation circles and left.

Being the only ones in the room Naruto attempted to stand in order to bring Kuroka to bed. Unfortunately however she had a firm grip on him which got tighter the moment he tried to stand. So, with careful movements he managed to slowly move them around in a way that they were both laying on the couch side by side. ''I guess a little nap wouldn't hurt.'' He mused as he slowly got comfortable in her grasp.

Naruto stood before Rias as it was time for him to see her skill with magic. Le Fay having put a barrier around his home before they get started. ''Well, show me!'' He called out to his sister who gave him a determent nod.

A red aura began to engulf her as Rias began to channel her energy. Soon a magic circle appeared before her as she released a beam of destruction that shot past him. ''Interesting.'' He muttered as he watched the beam carve its way into the ground. ''Can you do it again? Something bigger this time?'' Rias didn't reply as she shot another beam forward. This one bigger than the previous one evident by her using both her hands.

''Do you have anything that works from longer range?'' Seeing her confused gaze he elaborated. ''Not one of those beams you just fired. I'm talking about something that's more… instant i guess?'' He tried to explain to the best of his abilities.

''Alright here look.'' He said before pointing to a tree not too far from them. ''Watch this.'' The moment he said that a small magic circle appeared before him. Touching it Rias watched as Naruto began to pour his magic into it before flicking his hands in the direction the tree was at. The magic circle disappeared before reappearing, this time above said tree before it unleashed a bolt downwards completely encompassing the target before obliterating it.

''You see what i mean?'' He asked as he turned to face his sister who looked at him with shock.

''How? That was so quick.'' She exclaimed in surprise having watched his attack.

''I trained a lot with it. Eventually i started playing around and what you just saw was the result. A single target attack that's capable of hitting smaller targets. Depending on the amount of magic i put into it i can either increase or decrease the size of the blast.'' He explained.

''What about the cast speed?''

Naruto scratched his cheek. ''That's different it seems. That attack as you just saw took very little time to prepare while still being destructive. However its speed stays the same regardless of how much power i put into it. Some of my spells take a lot more time but they are much more damaging so most of the time it depends on the power required.''

''You said most of the time, what do you mean by that?''

''What i mean is this.'' As another circle popped in before Naruto mimicked Rias' earlier attack only faster. ''As you saw despite both attacks being the same i managed to fire mine faster. You might think it's nothing too important but during a fight having even a split second faster time can mean either winning or losing.'' He glanced at her to see her paying rapt attention. ''The best way for you to increase your casting speed is to practice a lot. It doesn't have to be that specific attack you just need to know how much power you need which is something you can only understand from experience.'' Rias nodded

He ran one of his hands through his hair. ''We can work on this however and perhaps i can even show you some useful tips when it comes to fighting Riser. I don't know if i can really help you with inventing new spells as that's largely based on the user's imagination as long as you know the correct amount of power required. Not to mention that it can take quite a bit of time which we honestly don't really have.'' Rias frowned a bit but nodded nonetheless. She would take any help she could get and she had just seen that Naruto was more experienced when it came to these matters.

''Let's get started t-'' He was interrupted as Issei's body came sailing through the air before he landed harshly and skidded to a stop a few feet in front of them.

Rias released a gasp as she saw the state her pawn was in and was about to run over to him only for Naruto to hold her back. She was about to ask him to release her before a black blur launched itself at Issei's prone form. Naruto already knew who it was so he wasn't surprised as Kuroka showed herself sending a kick at Issei's sides. The boy groaned as he was once more sent skipping, this time ending face up. From the corner of his mouth Rias spotted blood leaking out and wrestled herself out of his grasp before hurrying over to him.

''Issei!'' She yelled as she began to look him over. Careful as not to cause him more pain.

''You went pretty hard on him i see.'' Naruto commented as he stopped next to Kuroka. Much to his amusement Kuroka nodded her head with a smile, not bothered in the slightest that she almost crippled the boy. More footsteps alerted them and they looked behind them to see the rest of Rias' peerage hurrying over to the fallen boy. Rias quickly made room for Asia who began her healing as Rias sent Kuroka a glare.

''You didn't have to be so hard on him.'' She scolded her.

''It's his own fault nya. He wanted me to all out from the start. He should be glad i didn't listen to him and not used my boosted strength nya.'' Kuroka replied to her with a shrug.

Rias frowned as she listened to her and shook her head. So typical of Issei to say something like that. Always pushing himself to the limit regardless of how much pain he will end up with.

''Tell me when he's healed up so we can go again nya~'' Kuroka commented before she sauntered off.

Rias looked at her brother who shrugged his shoulders. ''What? You heard her he wanted a serious fight which he got and ended up hurt the only one to blame is Issei himself.'' Seeing she wasn't amused he spoke up ''Let's take a short break before continuing yes?'' She gave a nod but Naruto saw she was focused on Issei and walked off.

Menma, Sasuke and Sakura were sitting in front of a screen displaying both Kakashi and Minato who looked at them curiously. ''So, have you made any success?''

Sasuke shook his head. They hadn't. For the few weeks they've been attending school they hadn't come any closer to speaking with Naruto. In fact the most they've done was running into him on a couple occasions which didn't lead to anything. Not to mention that they were already quite suspicious of them, mainly due to Menma revealing their purpose of being here indirectly to the short white haired girl that was send spying on them. He was thankful Menma didn't spoke any names which was probably the only reason they were still allowed to roam free.

''I see.'' Minato replied with a frown on his face. It was a setback for them to not even make contact despite being there for little less than a month.

''Anything else that's important to note that has been happening?''

Menma and Sakura shook their heads whereas Sasuke spoke up. ''Yes, Menma has been acting strange the past few weeks. He said it was because of the mission but i think there is more to it than just that.''

''Really?'' Minato looked at Menma. Despite not being there in person Menma couldn't help but shiver slightly as his father looked at him. ''Are there any problems Menma?''

Blinking once Menma controlled himself before shaking his head. ''No father it's just that i think i could spend my time better than attempting to talk with him. No offense or anything but we have to be very careful as we're already being watched. It would look suspicious if we were to just walk up and ask to meet in private. Though that's not even to forget that he often isn't even there as we had to wait almost a week before we first saw him.'' Menma explained to his father who gained a thoughtful expression.

''But that still doesn't excuse you for not even speaking with him once.'' Kakashi's voice cut in. ''Just do your best alright? Your mother and father really want to meet him and if we have to we will send someone that might have a better chance than you three.''

''Very well.'' Sasuke said before the connection was cut and turned to the other two. ''We really have to find a way to talk to him. As much as i hate it they are right that it's quite a shame we haven't even spoke properly with him once. We need a plan that will doesn't look suspicious.''

''Can't we just like, talk to him during breaks or something?'' Sakura spoke up for the first time. ''Doesn't he often just waste his time underneath one of the trees with what's her name… Kuroka?''

Sasuke mulled over her suggestion before nodding. ''I guess we could. It's the best we got and worst come to worst he just doesn't like to talk to us but from what we've seen so far he seems quite open to other people as long as they aren't bothering them.'' He looked at Menma. ''You okay with that?''

The blond shrugged. ''Sound good enough for me.'' He replied as he just wanted to be done with this assignment. He had been experiencing weird urges lately and wanted to get it looked at.

Naruto could be seen sitting with his eyes closed underneath the shade provided by one of the trees surrounding Kuoh Academy. It wasn't a surprising sight for those who passed by as he could often be seen there during breaks when he didn't spend them inside the ORC building. His breathing was calm and he moved one of his hands through Kuroka's hair who was next to him resting her head on his chest.

No words were spoken as both just enjoyed the sound of wind blowing through the leaves and the distant chattering of other students.

''There he is.'' Sasuke said as he along with Sakura and Menma watched the two from a far. ''Ready?'' He got two nods in return before they calmly walked over to where they were. Making sure not to rush or do anything that can cause them unease.

Slowly Naruto opened one of his eyes as he felt three signatures heading his way. He was sure Kuroka had sensed them as well but apparently didn't react. With his opened eye he saw the three newer students making their way towards them.

The group noticed Naruto had noticed them as his lone violet eye kept them in his sight.

''Is there something you need?'' He spoke up as they stopped a few feet away from him. He opened his other eye before looking them over.

''Not really. We just wanted to talk.'' Sasuke replied.

Naruto hummed at his answer before motioning them to sit. Not wanting to annoy them he did what he was hinting at with Menma and Sakura mimicking his action.

''So,'' He looked down to see Kuroka still having her eyes closed. ''What do you want to talk about?'' He was wary of them. Koneko had mentioned that they were looking for someone and he was the first person they sought out which made him already slightly defensive. Normally he wouldn't be bothered like this but with three unknowns with the black haired one capable of using chakra despite not being a Yokai was enough of a reason. Not to mention that chances the other two are capable of using said power was pretty high.

Sasuke opened his mouth only for no words to come out. What was he supposed to say? They actually hadn't really thought about it much. Yes, they did have a discussion but he didn't expect it to be so easy. So what now? He can't just go ahead and tell him they are interested in him without coming of creepy.

So he went with something more inviting.

''We are just curious about you. We heard a lot of people talking about both you and…'' He glanced at the woman resting on his chest.

''So?''

''I- We were wondering if you could tell us something about yourself.''

''Something about myself huh…'' He muttered.

''Can you give me an… example?'' He asked him.

Sasuke knew he understood what was being asked but was still cautious of them. ''You know, likes, dislikes, dreams for the future?''

''...''

After not receiving a reply Sasuke was about to call it quits before he once more spoke up.

''My name, as you know, is Naruto Gremory. I like my family, traveling and relaxing with Kuroka-chan here.'' He nudged the sleeping Nekoshou. ''I would say that i enjoy a good… fight every now and then. My dislikes? Arrogant people and a certain bird i have the displeasure of knowing.'' He nodded his head at his own words. ''My dreams huh…''

Instead of replying he glanced down, a fond smile formed itself on his face. Kuroka slowly opened her eyes as she felt his gaze on her. Those violet eyes looked at her own amber ones, filled with warmth she could almost feel it. A smile of her own formed as she understood what his answer was and she was sure the others did as well and a warmth filled her chest.

Before they got a chance to ask something else the bell rang indicating next classes were about to start. Kuroka removed herself from him before standing up as Naruto followed her example. The two interlinked their arms before they walked off leaving the trio behind to watch at their backs.

''Well, at least we got something.'' Sakura spoke up after a moment of silence before she too rose to her feet. Sasuke grunted before he too stood up and headed inside, missing the moment Menma's eyes flashed red.

''Hehehe''

Menma held his head in his hands as he heard strange laughter before it was gone. Looking around to see if there was anyone he was unable to find anything and shook it off as imagination before he hurriedly ran towards his friends.

It was night, a few days before Riser would arrive at Kuoh.

Currently Naruto and Kuroka were busy with each other as moans echoed through the room, aided by the sound of flesh meeting flesh. Kuroka was laying on her back, her hands fondling her breast as she gazed at Naruto with half lidded eyes filled with lust. Her legs were resting on either side of his head which he held close to him with his arms as he moved his member in and out of her with a quick yet satisfying pace.

She shuddered as she felt him hit a particular good spot which didn't go unnoticed by him as a smirk formed and he began to pound with a certain angle to hit that spot.

''Nya~'' She moaned and increased the grip she had on her own breasts. It felt so good~ No matter how many times they did it neither he nor she could ever have enough from the pleasure they were feeling. Ever since the first night they spent together they had gone at it whenever they were in the mood which was very often. In fact the only times they didn't do it was when either of them felt too tired. When and where didn't matter as Naruto was able to seal the room shut allowing no sound to enter or leave enabling them to enjoy the other to the fullest.

Naruto turned his head sideways before he began to lay kisses along her calves while rubbing the other one with his hand as goose bumps began to form on her skin. Wanting to change things up a bit he moved her legs from his shoulders. Immediately Kuroka wrapped them around his waist as Naruto leaned down initiating a kiss which she greedily returned. The hands that were fondling her breast were now wrapped around his neck to keep him close as his thrust went from quick to slow yet deep. Her nipples scraping against his chest each time his hips met hers. Her breathing began to get heavier with each thrust.

She was close and he could feel it as his member moved between her slick walls as he increased the pace once more. Wanting to cum at the same time as she would.

Then, a minute or two later, it happened. With one hard thrust he embedded his dick in her womb before filling it up with his seed. Her legs locked behind him as her fingers dug into his skin as she threw her head back and moaned. ''Nyaaaa~'' Naruto had to stop himself from shuddering as he listened to her cries of pleasure as her walls began to constrict around his member. He idly wondered if all Nekoshou's moaned in the way she did as it was very sensual.

They stayed in that position for a moment. Her legs wrapped around him as she hugged him close to her body. Both sweating and breathing heavily though she wore a pleased smile as she felt his seed deep inside of her womb. It would only be a matter of time at the rate they have been doing it till she would be able to start repopulating her race. She felt him place soft kisses along her neck and mewled in pleasure while leaning into them.

She wiggled her hips, causing pleasurable jolts to run through his body. She wanted more and who was he to deny her.

However before they could indulge in another round of carnal pleasure a teleportation circle made itself known, right in there room.

''What?'' Naruto exclaimed before he quickly removed himself from Kuroka before covering both of them with the sheets that were laying aside. Both Kuroka and he watched as the glow disappeared and there, right before them stood his brother's wife and Queen, Grayfia with a serious expression on her face.

''Naruto-sama, is Rias-sama here?'' She asked urgently before she opened her eyes and gazed at both of them. It wasn't hard for her to know what they were doing, especially with the smell of sex still in the air.

''My sister, no why?'' He asked her. Much to his surprise she didn't really seem to bothered with the way she had interrupted them or that he was intimate with Kuroka. Then again she along with his family already knew the two were an item despite not bringing it up.

''I see, sorry Naruto-sama but this is an emergency regarding Rias-sama. I'll be off.'' She didn't give them a chance to respond as she activated another teleportation circle and left.

''...''

Naruto looked at Kuroka who gazed back.

''Let's take a shower before i'll go and check up what got grayfia all worried.'' Kuroka's ears perked up at that as she quickly made her way to the bathroom before him. He chuckled, she was quite the excited one, he thought as he too headed towards the bathroom.

Rias Gremory was a proud girl, a stubborn girl who took pride in being the heiress to one of the remaining families in the Underworld. She had been pampered from a young age. Always getting what she wanted from either her parents or her brother. Or at least almost anything.

There was one thing her brother couldn't do for her and that was to break the arrangement made between their house and the Phenex. They too were one of the few remaining Pillars in the Underworld with Lord and Lady Phenex having three children. Ruval Phenex, the heir of their family. Ravel Phenex who is the youngest. And last but not least Riser Phenex, the one she was betrothed too.

It was a nightmare really, for her parents to marry her off to some boy she barely even knew. A nightmare in the form of Riser Phenex. She really didn't understand why her parents had to set up an arranged marriage with him of all people. Riser was an arrogant playboy, who, she knew was just interested in her body. She shuddered at the thought of being married to that man. He would probably just use her as some sort of bragging right that he was able to fuck Rias Gremory. Why couldn't they set up Naruto with Ravel? She knew it wasn't a fair thought especially with how he was already with Kuroka but then she wouldn't have to worry about her future. Naruto was strong, stronger than her and would have a better chance at getting rid of any contracts that would have been made with him instead of her.

Her brother was nice enough to offer training to both her and her peerage in return of her helping to rebuild the relation between her Rook and his Queen. She had accepted it as it was heavily in her favor despite not telling Koneko about it.

However, even with the training they had received she knew the chances of winning were slim and as such she had come up with a plan. A plan that she thought would guarantee to succeed manage to backfire.

Issei Hyoudou, her Pawn had denied her advanced. She didn't know how it was possible as she was sure the boy probably dreamed of her whenever he would sleep but somehow managed to deny her.

She had visited him earlier, wearing barely any clothes in an attempt for him to take her virginity. She had read that if she would lose her virginity to someone not her fiancé the marriage wouldn't happen. So she came up with a supposed foolproof plan to allow her perverted pawn to sleep with her.

Never in her life did she expect him to deny her though. She was honestly not sure if she had heard him correct when he said ''No''. The surprise was clearly visible on her face even as she practically begged him to take her. She could see the fear in his eyes as he denied her each time she would move closer to him. She wasn't sure why he would deny her, perhaps because he knew something was wrong?

Unknown to her though Issei, with pain in his hart, denied her because of Naruto. The boy didn't even want to think about what he would do to him if he found out he had sex with his sister. Despite his improvement, which included him managing to land hits on him during the training he knew he was still out of his league. Never in any of their spars had Naruto used the Power of Destruction. Despite not having seen him using it Rias had told him he too was capable of using it. And as much as he desired Rias, with Naruto not allowing him to act out his usual pervertedness he managed to think clearly and decided he valued his life more than the chance to sleep with Rias Gremory.

Rias held her head down as Grayfia was busy berating her. Telling her she wasn't acting like the heiress of their family should and that she shouldn't retort to using these types of solutions which wouldn't even have worked as it would be seen as a scandal for their family name. Rias didn't reply once as Grayfia was right with everything she said.

Their attention went to the other magic circle that appeared not to far from them. Much to her horror the person who appeared was Naruto who had a disappointed frown on his face as he glanced at her.

Arriving at the location Naruto could only frown as he looked at his siter. Her hair was a mess and her eyes were bloodshot as she averted her eyes once they made contact. He had been informed of what happened and why she was in such a hurry by Grayfia and to say he was disappointed was an understatement. Never had he expected her to do something as low as this. He was proud of Issei though for being able to deny her as many others in his place wouldn't have.

''Can you leave us?'' He asked Grayfia. The woman looked at him before glancing at Rias and nodded as she teleported out of room.

Releasing a sigh he sat down next to her not saying a word as Rias did her best to hide her sniffles.

''Why?'' The question rang through her head as she still looked down.

''Why Rias?'' He repeated.

''I-i'm sorry nii-san..'' She said softly and he could see tears running down her cheeks. With a soft sigh he wrapped one of his arms around her before hugging her close to him. Feeling her brother's arms around him the dam broke as she let out all her tears while grabbing onto him. Naruto looked on with a frown as he ran one of his hands through his sister's crimson locks while rubbing her back with the other.

''You okay?'' he asked her after she stopped crying. He could feel her nod her head into his chest as response and allowed her to free herself. Rias however stayed in the position she was in as he was releasing a comfortable warmth.

''How about we go and watch some Anime, like we were younger? You can explain what happened tomorrow?'' Rias perked up at that before nodding with a smile on her face. She can't even remember the last time they watched Anime together. ''Great! I'll let Kuroka know i'll be staying the night here while you pick something out okay? She'll understand why.'' He said before detaching himself from Rias and teleported home to inform Kuroka. Rias watched him leave with a smile before she went off to look around her collection for something interesting to watch.

End Chapter.
