"I never thought that you would be a candidate for the hokage position Haru" ask Minato

"Hahaha well I was shock at first but I don't want it for now, I wanted to be free" said Haru

"Cocky brat! When you said that it looks like you will be the next hokage" said Tsunade behind them

"Eh! It's not like that" said Haru quickly

"Hahaha we know, so care to explain how you do it?" ask Tsunade

"Do what?"

"The bloodline thing" whispered Tsunade

"Oh right okay then let's all go to the 3rd training ground, Kakashi bring Shisui there too"

"Okay" Kakashi then left

After a while, the group reach the 3rd training ground, except for Fugaku since he separated from them when they got out the Hokage building.

Haru conjured his chains again in a dome shape and explained to them how the purification process works. When they heard it they all have a look of interest and also a wry expression since they don't want to feel intense pain, but the benefits are really good.

"So who wanted to get purified?" ask Haru

"Me, kid I want to take the risk" said Tsunade

Since Tsunade is the granddaughter of Hashirama she always wanted to be like her grandfather, but she was disappointed when she did not get his bloodline limit, so by performing purification she will have the chance to acquire the wood release.

Obito also raises his hands, Kushina too and even Minato. 

Haru then look at them and said

"Obito I won't purify your bloodline for now, since I wanted to make you get the 3 tomoe sharingan and evolve your sharingan to mangekyo sharingan before I purify your body at the same time purifying the curse of your bloodline, but don't worry I already know how to do that" said Haru

When Obito heard what Haru said he was at first disappointed but when he heard the later sentences he became full of determination.

"Kushina-nee I also can't purify your body, since Kurama is inside of you, I don't know what will happen if I suddenly purified your body, but you are already strong enough so the advantages of purification is insignificant since you already have Kurama's chakra to nourish your body" 

Kushina was disappointed when he heard Haru's words, since she also wanted to purify her bloodline but Haru is right she is already strong enough since in these past years she and Kurama have a good relationship and she can already use kurama mode completely.

"That leaves us with Tsunade-nee and Minato-nii okay then, how about jiraiya-sensei and Uncle Sakumo?"

"Hmm it is tempting but its fine" said Jiraiya

"You already taught me many things Haru, but its fine you already made Kakashi strong" said Sakumo

"Okay then Uncle, Jiraiya-sensei I will just teach you some techniques that can greatly help you in the future" said Haru

"Hahaha Okay then brat"

"Oh right Tsunade-nee"

"Yes?"

"I have a favor to ask" said Haru

"What is it?"

"I want you to have Rin as your disciple" said Haru

"Rin?"

"She is Rin Tsunade-nee, she is a good medical ninja, I can also teach her but I can't teach her all especially about poisons and there antidotes" Haru said pointing at Rin with a shock face

"Well hmm… Okay then" said Tsunade

"Rin come here" 

Rin awoke from her daze expression and walk towards Tsunade and said 

"Please take care of me Tsunade-sama"

How can Rin not be surprise, Tsunade is one of the legendary sannins and is an expert in medical ninjutsu, so she was happy that Haru ask her to be her sensei.

"Thank you Haru" said Rin

"Hehe it's nothing, I did promise you that I will help you train, but I will still teach you a thing or two, to help you become more stronger, I will also teach it to you Tsunade-nee"

"Oh what is that?" ask Tsunade

"Well…" 

Then Haru explains about observation haki and armament to them.

"Oh if what you said is true, it really helps us especially that observation haki of yours and it will help us avoid potential dangers especially we are medical ninjas." Said Tsunade

"Is this also the technique you want to teach me kid" ask Jiraiya

"Yes sensei"

"Very well, I also want to learn it" said Jiraiya

"So do we start now?" ask Tsunade

"Hmm we will just wait for Kakashi and Shisui" said Haru

Just after he said that Kakashi and Shisui both arrive in front of them.

"Oh you are finally here" said Haru

"So what are we going to do?" ask Kakashi

"Hi sensei" said Shisui

Haru nodded and said 

"Kakashi, I want you to teach Obito, Rin and Jiraiya-sensei about Observation haki for now and then once Obito and Rin have the foundation, then you can start to train them in armament haki. I will teach Jiraiya-sensei and Tsunade-nee armament after I finish purifying Tsunade-nee and Minato-nii's bodies"

"Oh okay"

"Shisui join Kakashi and further master your armament Haki before you go out on your missions" said Haru

"Hai! Sensei"

"What are you going to do uncle and Kushina-nee?"

"Well I will join Kakashi, I still want to perfect the techniques you told me" said Sakumo

"I will go with you and watch" said Kushina

"Okay then"

Haru then unsummoned his chains and teleported the 3 of them to his hide out outside of Konoha.

He then said to them

"Okay who will go first?"

"Minato you go first I want to watch the process" said Tsunade

"Okay Tsunade-sama" said Minato

"What do I do Haru?"

"You should strip all of your cloths nii-san" said Haru smirking

"Ehh! All of it?" ask Minato in a red face

"Yes, unless you want to burn your cloths, well you will still be naked either way" 

"Uhmm Haru can you made this in private" whispered Minato

"What's the matter Minato, I have already seen so many naked bodies while I'm healing, and Kushina is your lover she will see it sooner or later, while Haru here is a boy so what's the matter?" said Tsunade while smirking

Kushina's face turned red while blood drip on her nose when she heard Tsunade's words, but then she still nodded her head and said

"That's right I also wanted to watch the process"

'Well I'll be damn, who said men are the only perverts even ladies have perverted thoughts' thought Haru

Minato having no choice on the matter slowly strip in front of them. Well you gotta say to the soon to be 4th hokage he really is a fine specimen. 

Well we all know that Minato is indeed very handsome, his body is not bulky muscular but more of a swimmer, those lean well defined muscles, the firm chest, those 6 pack abs, a V shape body and oh boy let's not talk about his manhood which can satisfy the girls and even gays with its size and thickness, and the long firm straight legs, damn Kushina is very lucky. 

Haru seeing Minato in all his glory look at Kushina and gave her a thumbs-up. Kushina's nose continued to let out blood. 

"Ehem… Minato-nii let's start, sit cross leg with your back facing me" said Haru

Haru then manifested his bloodline and made his hand signs 

[Phoenix secret-art: Body Rebirth jutsu] 

A golden flame manifested in his hands and he directed the flames to Minato's body, the golden flames covered his whole body, Minato screamed in pain but he endured.

After a while, the flames dwindled and Minato's exhausted body laid in front of Haru.

 Haru then took out a blanket in his space ring and covered Minato's body; he carried his body in the corner and asks Kushina to watch over him.

"Is Minato alright Haru?" ask Kushina worriedly

"He's alright Kushina-nee he is just exhausted and falls asleep he will wake up soon" 

"Okay then"

"Tsunade-nee it's your turn" said Haru

"You close your eyes brat" said Tsunade

"No fair how can I see if I close my eyes?" lied Haru

"Tsk! You close your eyes or I'll pluck them off" said Tsunade

Haru having no choice close his eyes, until he heard Tsunade

"Okay you may start"

Of course Haru can still know where she is due to his perception so he directly made hand signs and uses his technique to purify Tsunade's body. 

He heard her scream in pain and after a while, he perceives that the purification is over.

Tsunade's body lay in front of him, he took another blanket and wrap her body and carried it back to Kushina.
