"Hey, want ta cum and hang with us?"

'Seriously, these types of guys even exist anymore?' Kuroka, cat form, thought as she rode on top of Naruto's shoulder. The truck that had all of his stuff, moving him to his new temporary apartment, was already unpacked. Now all that was left was to attend his first day of his new school classes. She usually jumped off of his shoulder before he got into the school building itself, and enjoyed the usual ride that she got until that moment.

Gangsters, Yakuza-wannabes, who looked to be picking on a girl, ready to sexually assault the girl or something.

Kuroka honestly didn't care about this kind of stuff.

Naruto already had a yo-yo out, and spinning in his hand as he started to walk by the scene. Naruto didn't look at the girl, or even the three wannabes, he just started to play with his yo-yo. The girl had her eyes closed, and had pretty much accepted what was about to happen to her.

"Maybe instead of assaulting girls, you three can pick up a hobby, like walking a dog." Naruto spoke as he got right next to the boys. With his yo-yo tossed out, he wrapped it around one of their ankles and grabbed him. Yanking up on the yo-yo, he tripped the boy so that he landed face down. Naruto stepped on the first boy's back and pulled up his yo-yo, before throwing it with enough force to smash into the second boy's temple, knocking him out and onto the ground. Naruto stomped his foot on the boy he was standing on, and caught his yo-yo when it came back to him.

The third guy threw a punch.

"You bastard!"

Naruto, still walking away from the scene, wrapped his yo-yo around his arm and yanked on it, making the guy punch himself in the face. Jumping, Naruto kicked the man in the face, knocking him into a brick wall, before he landed on top of the first guy.

"Kuoh seems to have a delinquent problem... I like this place already, feels just like home." Naruto spoke fondly as he continued on his way to school. The three defeated losers moaning in pain on the ground, still surrounding the close-eyed girl as she shivered in place.

Kuroka mewled, a shiver of excitement went down her spine when she saw a good display of violence.

Naruto might have not yet awoken the "Wind" of his bloodline, but his Demon Slaying powers were both Wind and Martial Arts. While she wouldn't call what he was doing true martial arts, the innate skill that he fought with got better and better every single time he fought anything. A year ago, those three goons would have forced Naruto to get into a tough fist fight with them, Naruto would still win of course, but now small time thugs like that were nothing.

'If the only people after him were stuff like that, I wouldn't even be needed... until he awakens his blood fully though and trains with it, he'll still need me to protect him from the supernatural.' Kuroka thought privately, glancing back at the goons. Naruto's powers, at the rate his martial arts were growing, should be awakening soon enough.

Once those powers awakened though... that was going to open up a new can of worms she was going to have to deal with. Stronger Ayakashi would try and take him down, and worse case was the other active Demon Slayer families catching wind that Naruto's family had a member who had strong powoers.

"Aaaah, you're worried, don't worry... I only hurt them enough to teach them a lesson." Naruto rubbed the bottom of her chin, when he noticed she was looking at what he did.

Such a worrywart of a cat he had.

Kuroka rolled her eyes.

'I'm more worried about the fact, that despite having a Kuoh uniform, you chose to wear something that makes you look like a delinquent... something that you are anyway.' Kuroka realized that everyone who had been ignoring what was happening to the girl earlier, because yes people saw what was happening and chose to ignore it, were sending Naruto suspicious looks.

Naruto was the good kind of delinquent... if such a thing truly existed, it was him. He helped any old lady that he saw in need of him, he saved people who looked like they needed saving. If an animal was in trouble, Naruto went out of his way to go and rescue it, and drop it off at the shelter. When other delinquents acted up, Naruto taught them a much needed lesson on which direction their moral compass should point.

She kind of wished Naruto had a more gray compass himself though.

"I think he saved that girl, so he wouldn't have to worry about getting their sloppy seconds later."

Naruto faced two kinds of people for the most part, in the adult world at least. Adults who knew Naruto was the heir to the Namikaze company, the heir to a super rich family, and made sure not to make their negative opinions heard. Then there were those who didn't know, so they opened their damn mouths and spoke the nastiest of lies about him when they saw him.

'I blame the school system. So many students seem really accepting, but the teachers really beat the idea in these human's heads that they had to adhere to what they say is normal.' Kuroka, after several years in Japan, was really coming to dislike her own native country. Her species were Japanese born, though she was born in the Underworld.

No wonder the Nekomata (Nekoshou) of the past used to commit really heinous crimes against humans, humans were assholes who deserved it for the most part.

She was so going to-

"-prank the teachers at the school first... gotta make my first day at school something nobody will forget."

'A man after my own heart.' Kuroka nuzzled into his neck when he practically finished her thought for her. She loved messing with people, and her 'master' loved to pull pranks on people. Not to mention he was born into power and wealth, with great genetics that she could pass down.

Hot body, good personality, and he could promise a life of comfort for her later on... she was really going to love it when his powers matured.

Once that day came, she would make the stuff she did to him in his sleep look like child's play.

-At Kuoh Academy-

"Okay class, today I'll be introducing a new student... his name is..."

'A new student... but the school year just started a few weeks ago?' A young, 15 year old looking, girl thought as she raised her head a little bit. In her full uniform, her body was hugged tightly enough to show her very petite frame. A near complete, near complete, lack of breasts that normally were used to denote age. Chin length white hair, with sides that went below her shoulders. Bright yellow, cat-like eyes, and an overly small physique.

The only thing about her that showed that she wasn't a child was the fact that she did have boobs, however small, and the fact that her hips and rear end were more matured than the rest of her.

Koneko Toujou.

What kind of student joined a new school, just a few weeks after the school started up? Such weird timing if you asked her.

*Crash*

A large black blur crashed through the window and rushed so that it was right in front of the teacher's desk. Koneko almost jumped out of her chair in surprise, having no expected that, but everyone else in the class didn't have her control. They all jumped and screamed a little.

"Naruto Uzumaki-!"

The black ball unraveled, showing that it was a large jacket, and the rest of the person inside uncurled from a ball shape, and landed on the floor. Skidding across the ground on his feet, Naruto threw a yo-yo out and grabbed the chalk from the teacher's hand. As he skid across the floor, Naruto started to write his name on the blackboard, and threw the chalk back into the teacher's hand as he finished writing out his intro.

"-has arrived, and you better remember my name! I'm going to be the Souban of all Japan one day."

...

The class was stunned into silence when Naruto slammed his hand down on the teacher's desk, and pointed at his intro.

"See, is says it right there... take a picture now, you'll never know when one day you'll need to prove you were in the same class as me." Naruto grinned and gestured to his signature. "I'll pay for the window, but the way... though I might break it again." Naruto gave a thumbs up.

The teacher just, give him credit, rolled with it.

"... Wow... what an annoying guy." Koneko whispered just barely loud enough for Naruto to hear.

He was so loud.

"The hell did you just say you little shrimp!"

Naruto heard her, and he was on her really quickly, grabbing the front of her uniform and lifted her up into the air. A small vein bulged on his head, and a similar one on hers.

"Shrimp?!"

The two of them glared at each other, before Naruto dropped her back into her seat, and walked back to the front of the class.

"Listen up, I want all of the toughest people in this school, to step up and fight me! Spread the word!" Naruto loudly proclaimed his challenge. Surely, with how gossip worked, he would have a line of challengers waiting for him by the end of the day... or the next few days at least.

Koneko glared at Naruto, before she looked at something that was hanging from his chest, and her eyes widened for a second.

A silver cross.

Not good.

'This guy really is annoying... the issue, does he wear that because of faith, or because he thinks it looks cool.' Koneko thought when Naruto sat next to her, next to the window. She glared at him, and the second he noticed her glaring, he started to glare right back.

He even pointed at her.

"Shrimp."

"You're not too tall yourself." Koneko pointed out under her breath... sure, she was only 138 cm tall... but he couldn't be more than 166 cm himself.

Naruto twitched.

"I'm a 15 year old boy, and still growing... what is your excuse. You look like you belong in the Itty Bitty Titty Committee."

Oh, he better pray that her master not allow her to fight this guy, because she was really hoping to throw a few punches at him for that one. Their insults at each other were soft enough to not disturb class, but Koneko couldn't remember the last time that somebody was able to annoy her so easily before now.

"Nimrod."

"Hah, that's a compliment. That's the name of the world's first hero, looks like your brain is as small as... well, I won't go that far. Nothing is as small as your breasts."

Screw annoyance, she was pretty sure that she was going to beg Rias to give her a chance to fight this guy. He had made fun of her boobs several times now, he needed to pay for that.

"... still bigger than your di-"

What Koneko didn't know, was that just like herself, Naruto had a really nasty temper that was just as quick to flair up. She had just decided that she was going to insult the one thing, that nearly every man alive held some sort of complex about. By comparing his manhood to her breasts, considering how small they were, and the fact that she already had him angry at her... well... Koneko was not expecting to get tackled out of her chair.

"That is it, you're my first opponent!"

-10 Minutes Later-

'That little bitch sure hits hard.' Naruto rubbed the ice pack over his eye, with his other arm being wrapped up in bandages by the nurse. She had given him a good number of decent licks, but he had gotten in some good shots of his own. She had given him a busted lip, bruised ribs, and a black eye sure... also he was thinking he broke some knuckles. 'Also... she takes a punch really well too.' Punching her had felt like he was punching a soft brick wall, his punches had connected, but as soft as her body was... she was really durable.

Koneko had a black eye and a bloody nose, with a bruise on the on her shoulder.

'He knows how to throw a punch, I'll give him that... even if I was holding back, he was able to take those punches really well...' Koneko hated the fact that she had taken a few well aimed punches. Punches weren't just about how strong you punched, it was also about where you punched, and how you punched.

He knew how to throw a punch, and make it hurt... and he had a surprisingly good body for a human.

She really did not like him.

"You're still a shrimp."

Koneko jumped at Naruto this time, fist already pulled back.

It was the start of a beautiful relationship.

*Seriously, watch Naruto Gakuen on youtube or something. Naruto fought a gang with a yo-yo, and "High School" Naruto DOES wear a cross.
