In Naruto Universe, time travel to become Naruto's sister

Lvchi's fingers began to glow blue, and began to draw one after another in the air.Those unsealed forms will only stay in the air, motionless.Creating an unseal formula in mid-air is something only a seal master can do.After 5 minutes of non-stop drawing of the seal, Green Pool completed the production of the key.The moment the last seal was in place, the entire seal array collapsed from the inside out, shrinking into a real key.She then approached the cage containing the visibly excited Nine Lamas and began slowly removing the seal above the cage's keyhole.Just before she took it off completely, a strand of chakra inside began to escape, turning into an adult, and he immediately grabbed Midorichi's hand to prevent her from lifting the seal.

"You shouldn't have unlocked it."

This person is Namikaze Minato, the late fourth Hokage, the father of the twins, and the great hero of Konoha Village. Although he has passed away, he will always live in the hearts of Konoha villagers.

Minato has been observing the world through Midoriike's eyes, but he doesn't know how to do it.Because I can't see Midorichi's state of mind, I can only judge based on what she did in Konoha.She is obviously not a normal child - she has knowledge and abilities that she shouldn't have, and she has rich experience in survival.On the other hand, she does her best to protect Naruto, who is clearly a normal child in Minato's eyes.Although he doubted her, he was also grateful.However, releasing Nine-Tails is an entirely different matter.No matter what lies Kyuubi gave her, Minato had to convince her not to unseal him.He had already thought of countless meeting scenes in his mind, and he involved countless conversations in each scene, but Green Pool's next move completely disrupted his plan.

She rolled her eyes at him and started talking.

"Yes, yes, oh Dusang (Dad), let's talk about this later, what you have to do now is to hug the little one behind you."

He expected Green Pool to be affected by Nine-Tails.Burning with anger, unconscious, but casually greeted him, and even knew who he was?What happened?

However, before he could think deeply, an orange-yellow shadow hugged him.

"Dad!!!"

The caught Minato instinctively started to fight back, and suddenly remembered what Naruto called him, and stopped in the attack.

Dad?But the green pool is there.Is it Naruto?Why is he here too?Are their moods connected?

However, seeing Naruto who was hugging him and crying, he quickly pushed away the extra thoughts and began to hug Naruto to comfort him.

Unfortunately, Green Pool took advantage of that momentary distraction to quickly break the seal, push the key into the lock, and open the cage.

Minato's eyes widened in horror.

"What did you do? Why did you release that monster?"

Minato quickly walked up to Midoriike to protect her from Kyuubi's attack, but to his surprise, the expected attack didn't come.Although the cage had disappeared, Kyuubi was still lying on the ground, looking at him like an idiot.

"What's going on? Why not..."

"what is the problem?"

Before Minato had time to think clearly about the situation, another person appeared.Dark red hair and purple eyes.The mother of twins, Kushina Uzumaki.When she felt that the seal was lifted, she was naturally ready to help Green Pool control the Nine-Tails Chakra, but she didn't know what to do in the current situation.

Green Pool seems to be completely unaffected by Kyuubi.Why are Naruto and Minato here, and most importantly: why didn't Kyuubi attack us?
Kushina was about to ask some more questions when she was treated the same as Minato.

"Okasang (mother)!!!"

A hug fell to the ground.Her reaction was much faster than Minato, and she immediately hugged Naruto back.Although she doesn't understand the current situation, it doesn't matter.

While Kushina distracted Naruto, Minato quickly approached Midoriike to understand the situation.

"Green Chi, what's going on? Why doesn't the monster attack us?"

Out of the corner of Luchi's eyes, she saw that Jiu Lama was getting a little angry, and she couldn't stand being called a monster, so she decided to explain clearly.

"Well, to make a long story short, Kyuubi and I became friends. I released him from his cage so he could roam freely in my state of mind, and in return he wouldn't try to break free from my body."

Instead of calming down, Minato became even more angry.

"What! You befriended that monster? You can't trust it. It's going to betray you and stab you in the back—"

Nine Lama's last patience finally ran out.Well, in any case, he's never been so verbally insulted.

[Stop calling me a monster!You know what you're talking about, that butcher named Yellow Lightning? 1000 people!You kill so many people in one day and call me a monster? ]
Minato was about to retort, but Kurama was obviously angry, he didn't give Minato a chance to retort, and continued talking.

[That bastard Madara hunted me down, enslaved me with his disgusting eyes, and forced me to fight Hashirama, and I'm a monster?That Hashirama bastard not only hunted down me, but also hunted down all my brothers and sisters, imprisoned us, and then gave us as gifts to other villages, and I am a monster?As soon as I get another chance to be free, another person will jump out and try to use me and deal with me. I did something wrong.Do you really think I care about your seedy little village?In another 200 years, it will be gone anyway, destroyed by the greed of other humans, like every civilization you humans have created so far has been built by enslaving, destroying other civilizations, and I just want to live free.I have been imprisoned for over 50 years.In those years, I didn't say a word.Green Pool was the first person in centuries with whom I had a normal conversation, so we became friends.I only endured your existence because of Green Pool, but I really can't stand it anymore. ]
Without saying a word, the Nine Lama turned around and walked towards the forest, leaving a group of embarrassing people silent.

"Oh, you made him angry. It seems that it will take me a while to coax him well, Dad, you should really talk less, Jiu Lama is too emotional."

The first one to react was Minato.

"Is that true? I mean, does it say so?"

"First of all - you have to treat him as a creature like us, preferably as a human being too, I'm pretty sure you can answer that question yourself. Is he telling a lie. Look at Konoha's history and you'll know the truth."

Minato was dumbfounded when he heard this.He never bothered to think too deeply, thinking that Nine-Tails should be sealed up, now looking at it from another angle, it's really a mess.He couldn't even refute it, because it was written like this in Konoha's history books.

"*sigh*, he probably doesn't care about my apology, or even bother to listen to me, but I wish you could tell him I'm sorry for calling him a monster."

"Of course. He might pretend he doesn't care, but he'll be secretly happy to apologize to you."

"You seem to know him well, don't you?"

"Haha, of course, me and him. But that's the end of the small talk. I think we need to talk about something. Just the two of us."

Hearing Midoriike's words, Minato's face became serious.

"Indeed, although Green Chi is his daughter, she has many secrets that Minato cares about very much. He can't guarantee that Green Chi will tell him these secrets, but as long as there is a glimmer of hope, he is still willing to listen.

"Kushina, Naruto, I have something important to discuss with Green Pool in private."

Although Kushina knew what Minato wanted to talk to Lvike about, she would rather spend more time with her children than waste time "listening to something important".Just as she was about to start complaining about Minato, Naruto hugged him even tighter.

"Don't worry, Mom. If it's my sister who wants to say something to Dad, then it must be very important."

To this, Kushina really had nothing to say.Naruto seems to trust Midorichi completely, and from what she's seen so far, there's no reason to have any doubts about her own daughter.

"Okay, then I'll stay by your side."

Naruto nodded while enjoying the time with his mother.

However, what no one noticed was that after seeing Kurama's outburst, Naruto made a resolution to himself.

"I will definitely be his friend too!"

Meanwhile, Water Gate and Green Pool were walking into the forest, and stopped after being out of hearing range.

"So, tell me, Green Pool, who are you, and what is the purpose of appearing in Konoha?"
