Naruto walked around looking for his elder brother with a soft sigh as he was looking around "Damnit Kyojuro-nii where are you?" Naruto asked himself out loud, what he didn't realize was that he was being followed until he heard the heart beat behind him and he turned around "Huh?" He said until he looked at the person following him and smiled when he realized who it was "Mitsuri-chan!" Naruto shouted seeing the pink haired Hashira following him, he smiled brightly at her as she seemed to realize who it was.

"Naruto?" She asked as Naruto nodded and she squealed a little as she cuddled him pushing his head between her breasts making him blush, she smiled a little "I haven't seen in you a while, how have you been?" She asked as if talking to a little child as she let him escape from her grasp and pant a little.

"I recently became a Mizunoto and got my Scarlet ore for my Nichirin blade, I just need to send it away with the design I want for my sword" Naruto said as Mitsuri nodded and then Naruto seemed to be thinking "Actually do you know where Kyojuro-nii is?" Naruto asked as she nodded slightly "Really where?" Naruto asked and she replied.

"He's in a meeting with the Oyakata-sama with a couple of the other pillars" Mitsuri replied as Naruto sighed and nodded, he then looked around.

"Do you know somewhere I can go to change, I need to put on my uniform before I see Kyojuro-nii" Naruto muttered as Mitsuri nodded and pointed him to a large house which was surrounded by wisteria trees.

"The Butterfly mansion, I'm sure if you mention to someone there that you are looking for somewhere to change they will point you somewhere and then let you change" Mitsuri said as Naruto smiled and nodded, he turned around and waved over his shoulder as he walked off towards the Butterfly Mansion, upon reaching the door he knocked and one of the servants opened it and looked at him with confusion "Would it be alright if I used a changing room or a spare room to change?" He asked as he held up his uniform and the servant nodded and started to lead him towards the spare room he could use to change into his uniform, Naruto smiled and thanked the servant as he walked in and started to change, he came out 15 minutes later after checking he had everything especially his Scarlet ore for his blade he walked out and walked towards the door, upon reaching the door he saw it open and saw the girl from Final Selection there "Oh hey you just passed didn't you?" He asked as she looked at him surprised and she flipped a coin, confusing him, before it landed on heads and she nodded "I hope we can work together sometime, my name is Naruto Rengoku, younger brother of Kyojuro Rengoku the current flame Hashira" he said as he out stretched his hand towards her, to his confusion she flipped a coin again and then nodded as it landed on heads and shook his hand before replying.

"I am Kanao Tsuyuri, the apprentice of Shinobu-sama" she replied neutrally as Naruto smiled a little.

"It's nice to meet you Kanao" Naruto said and then smiled more "I hope to see you again some other time" He said before walking out of the butterfly mansion leaving a confused Kanao, she stood there for a small while before she walked to get changed into her own uniform.

Meanwhile, Naruto was walking around the HQ grounds until he heard his older brother shout to him "Naruto!" Came the voice of his older brother, Naruto turned around and saw his brother wasn't alone but was with a, in Naruto's opinion, creepily smiling woman.

"Kyojuro-nii, who is this?" Naruto asked seeing the woman.

Kyojuro was about to reply but she beat him too it "My name is Shinobu Kocho, insect Hashira and master of the Butterfly mansion, as well as the best doctor the Demon Slayer's have" Shinobu said as Naruto nodded and then asked without hesitation.

"Your heart's rhythm sounds angry at something" he said and then asked "What are you angry at?" He asked surprising his older brother although his brother knew that Naruto's hearing was amazing. Shinobu looked surprised as her mask slipped a little from the surprise before she put it back on.

"I best get going" Shinobu said in a slightly happy but pissed off tone "It was nice meeting you Naruto-san and thank you for introducing me to your brother Kyojuro-san" Shinobu said as she walked off.

Naruto stood there stunned and confused "What was that about Kyojuro-nii?" Naruto asked confused as he heard her heart in a complete mess of emotions. His brother looked at him and sighed.

"No one has ever known that Shinobu-san is angry and was surprised and angry that you figured it out" Kyojuro said before turning to Naruto and holding his hand out "Anyways I will need your Scarlet ore to send off to have your Nichirin blade forged" Rengoku said as Naruto nodded and handed Kyojuro the palm sized ore as Kyojuro shook his head and grinned "In the main time though we will train on your breathing capacity while also trying to get you to master Total breathing concentration and getting you to get faster, stronger and more flexible" Kyojuro said as Naruto nodded.

-1 week later-

Over the past week Naruto had trained and his brother pushed him to his limits, broke down those limits and made sure that Naruto had new limits, his total breathing concentration was considered mastered as he was able to use breathing concentration 24/7, he also increased his breathing capacity so he was able to use more techniques consecutively, his strength he was able to carry almost 3 to 4 times his own body weight, he was able to run around the whole demon slayer corps HQ in a little over 1 minutes so he was fast, especially so for his age and his flexibility he was able to practically fold his body in half and then fit into small cupboards and closets, as for what kind of gourd he can break he could break a gourd about the size of his torso which surprised the Hashira's at his progress, currently Naruto was sat next to his brother meditating as his ear twitched slightly and Naruto looked to the gates "It's finally here" Naruto said as Kyojuro looked confused and Naruto finished "My nichirin blade" he muttered surprising Kyojuro, as soon as Naruto said that both of them stood up and walked to the front gates and saw Haganezuka stood there with his mask on, once Haganezuka saw the two stood there he assumed it was the shorter ones blade as he knew Kyojuro already and held out the blade to Naruto, Naruto gratefully took the blade and lightly ran his hand across the sheathe it was in before he rubbed the handle "Do you have a cleaning and sharpening kit I could buy?" Naruto asked Haganezuka who seemed surprised at the inquirey as he nodded.

"Yes it will be 250 yen for the kits together" Haganezuka said as Naruto nodded and handed him the money he would need for it, once getting the cleaning kit Naruto looked to his older brother, Naruto looked down at the sheathe and then looked up to see both of them looking expectantly at him, as if sensing the confused Haganezuka finished "Well draw the blade, we wish to see what color you get" he said as Naruto nodded slightly and then put the cleaning and sharpening kit up the sleeves on his haori and then grabbed the handle of his blade before drawing the blade, once he drew it the blade shined a bright red and then the color shimmered into a bright white color.

"Bright white?" Naruto asked as the two looked confused as they nodded.

"I've never seen bright white before, have you Rengoku-san?" Asked Hotaru getting a shake of the head from Kyojuro as Naruto sighed and sheathed his blade.

"I guess I'm the only one to ever have it then" Naruto muttered and then stretched a little and turned around "So Kyojuro-nii I'm going to go start getting my missions now" Naruto said as he walked off into the HQ.

A/N: I'll be honest I don't know what else to write, so next chapter will be his first mission, then we'll have the Rui arc and Naruto will be acting as backup along with Giyu and Shinobu with Kanao.

Ja ne.
