2 days.

They had not left Naruto's apartment in two days, but that wasn't to say that he treated them badly either. If they asked him for something, he would go out and get it for them, but he didn't let them leave the apartment on their own. Just like he had said, and when he was at the apartment he was either taking care of his plants, toads, working out, he he was browsing the internet looking at animal facts.

Right now, he was working out.

'I hate this feeling of being trapped, but at least he is handsome and has a pretty good body.' Hanabi thought as she made eye contact with her sister, who had also been stealing glances at the man doing sit-ups. He barely talked to them for the most part, he asked them what they needed in the morning, but other than that he didn't seem to really know how to talk to people for the most part.

He was very informal as well.

He called them by their names with absolutely no honorific behind it, and while he didn't care if they used them with him or not, he seemed confused when they showed some reaction to him just casually using their first names.

"So... Naruto-kun... do you have any hobbies?" Hinata asked Naruto to try and get him to open up to them more. He was not cold to them or even distant, but he honestly seemed like he just didn't know how to hold a conversation with people when it was a topic he didn't care to talk about. "... Also, why do you want to... risk your life?" Hinata asked a second question, since she still could not wrap her head around somebody so willing to throw their life away just for somebody else to make money off of his death.

Naruto didn't need to think about it.

"Don't know, my parents did it, so I was born into this. Honestly though, when it was explained to me it sounded fun. I'm way stronger than most people, so having real challenges just gets my blood boiling... if I die, well I'll go out having a good time." Naruto finished his sit-ups and started to do push-ups with one hand. Hinata blushed, but she was able to control her reaction for the most part and not react physically.

The more hormonal teenager that was Hanabi clenched her legs together a little bit while sitting on the couch, since while he was athletic and lean, the pure muscle definition on his body was stellar. Not to mention he had some nice pecs and shoulders on him, to the point that she was sure she would bruise her knuckles if she punched his chest.

Naruto's phone went off, and he stopped working out and dashed across the room with an excited smile on his face.

...

"Yes! My Killing Bites match is tonight, and my opponent is a veteran as well, Brute Bear, of this is going to be a fun fight!" Naruto shouted out like a child in a candy store. All of the seriousness that he had before was completely gone, and he acted like a teenage boy that had been gifted with his first porn mag. He did a little dance, and the sisters just had to look at each other.

"Brute-"

"-Bear?" Hinata finished for Hanabi, since that sounded like a strange name.

"Oh, those who participate in Killing Bites go by the Title of Brute, I'm Brute Fox, just like how my mother was Brute Fox and my father was Brute Toad. Anyway, since you are new investors you are going to have to come with me and watch in person." Naruto told them as he started to calm down from his excitement.

"We have to go?" Hanabi asked with a shocked tone.

She didn't want to watch a death match!

"Do we re-really-"

-Later that Night-

'We really came...' Hinata thought as she looked around at the private park that was owned by a big company, and how it wasn't visible from the outside of the park. Naruto was wearing only his boxers and a loose fitting T-shirt that exposed his chest and arms, the sleeves of the shirt ripped off by Naruto himself.

Naruto was throwing punches test punches at a tree, putting cracks in the tree with each punch that he unleashed against it. Hinata gulped when she realized that she might just watch as Naruto beat a man to death.

Her sister was feisty, but right now when she looked at Hanabi the girl was visibly nervous and pale at the thought of what she was about to witness.

"Well, it seems that my rookie opponent has quite the built body, and he is certainly quite the energetic young man, are you ready?"

A man taller than Naruto by a small amount came forth, and his body was covered in bulky muscle in contrast to Naruto's lean muscle. Hanabi and Hinata lookedbat each other when they recognized this guy as a famous sumo wrestler that beat nearly all of his opponents with one slap each.

"Fuck yeah, lets kill each other." Naruto closed his eyes. "What is the name of my opponent?" Naruto asked with a grin.

"Jerome Hongou." Jerome stated as he tossed the top of his kimono down around his waist, and his eyes turned blood red and started to glow. He gained a blue aura around his body, and that surprised both Hinata and Hanabi.

Naruto showed no reaction but a grin.

What!?

Brown fur started to grow across his body as his height and muscle mass increased greatly, his body changing shape. Hanabi collapsed onto her behind as she looked up towards the tall man become an absolute monster in both shape and form, all of his teeth becoming sharp and dangerous looking.

"Brute-"

"-BEAR!" Hanabi finished for Hinata when she realized why that name was so fitting.

"Naruto, don't fight, this guy is going to..." Hinata stopped shouting when she looked at Naruto, and she saw his eyes had turned blood red and glowed as well. He grinned and showed that all of his teeth were sharp, and his canines had gotten even longer than before. Her eyes widened and she looked at Hanabi, who had also noticed that.

Jerome fully transformed so that very little of his human appearance other than his muscular (and now mostly fur covered) torso remained human.

Jerome roared at Naruto.

The bear, with powerful open handed strikes, they are capable of dealing savage and fatal damage to their victims with a single blow.

Jerome rushed towards Naruto.

"I'll end this with one strike, BEAR PALM!" Jerome shouted out as he unleashed a powerful attack at Naruto.

Naruto grinned and vanished from view.

'He vanished!' Jerome thought as Naruto appeared in the air upside down behind him, both of his arms and legs transformed into more animalistic forms. His legs fully transformed into those of a more muscular fox, while his arms transformed up to his elbows with his hands ending in large paws.

The fox can run with amazing speed, with a healthy male fox being able to reach speeds of up to 45 mph (72km/h), making a healthy fox nearly as fast as some of the fastest land mammals.

"He's Brute Fox." Hinata whispered as she saw the fox ears sticking out of the top of Naruto's head, and the bushy tail he had grown. Naruto was grinning a savage grin of glee as he flipped and landed behind Jerome.

Naruto landed on his feet as Jerome turned around.

"I've got you know, Bear Pa-"

Naruto's claws came out as he sped towards Jerome and slashed 10 deep cuts into his chest, going underneath his extended arm in order to do so. Jerome stepped back in shock when he looked down and saw that his chest had been deeply injured.

"Strike." Naruto stated the name of his attack with a grin.

Blood spurted out of Jerome's back, when the 10 slash marks appeared there as well, Naruto having slashed Jerome with all of his claws twice. Naruto didn't stop the grin from appearing on his face since he knew the wound he inflicted would allow for Jerome to keep fighting. He made sure that his claws were only a fourth of the way out of his paws when he unleashed his attack.

"I've already found your weak points and vitals, you can surrender, or my next attack will finish this." Naruto stated as he jumped over Jerome when he slashed at him. Naruto landed on the other side of Jerome, before he situated himself by taking a couple of steps to the right.

Jerome grinned in his bear form.

"It would be a disgrace to surrender, we fight like true men." Jerome stood up fully.

Naruto placed his paw against the ground.

His claws came out, much further than they did before, and he grinned a dangerous grin as he looked towards Jerome. Naruto's pupils became even finer slits, and his eyes narrowed.

"Fine."

'He moves much faster than I do, but at those speeds he has to move in a straight line.' Jerome looked at Naruto.

"BEAR-"

Naruto rushed to the side, before he quickly changed directions and ran his claws along Jerome's chest and arms. His movements became completely erratic, making a sharp turn that he shouldn't be able to make.

Unlike all other members of the canine family, the fox has retractable claws slit pupils like a cat, and allow them to make sharp turns when running, and with their light weight making them unpredictable hunters.

"True Strike." Naruto stated as Jerome transformed back to normal with extremely deep wounds across his chest, back, and arms. He would survive, but he was out for the count, and would die if he didn't recieve quick medical attention.

Hanabi's eyes were glued to what happened.

Hinata just covered her mouth.

What had she agreed to?

"Oh... yeah, I like this feeling... I really like this feeling." Naruto grinned as he transformed back to his human appearance and looked at his hands, before he gripped them into fists.

He wasn't surprised.

He understood why his parents loved Killing Bites.

He loved it too.
