The two man team moved forward rapidly to the location where the male sensed the space fluctuation.
"Minato, how much time it will take to arrive at the location? Ahhhhh! It better be something good, otherwise..."
"Now now Kushina. Don't get angry. It's our duty to locate the cause of space fluctuation and report it back to the village."
"Hmph! Ok"
The two continued to move to forward while bickering along the way. They increased their speed and quickly reached the location. On their way they thought that it be caused by some summoning beast. Judging from the space fluctuation, Minato determined that it be a huge summoning beast. So when they saw that it was not a beast but a human, they quickly raise their caution. A human capable emitting such fluctuation might be someone more proficient in space related ninjutsu. Beside second hokage's 'Flying Thunder God Jutsu', Minato never heard of any space ninjutsu. They stepped on a tree and began to observe the human while hiding their chakra.
Standing there was a 10 year old boy with pale skin, shaggy white hair and attractive features. The weird thing was his eyebrows. They have never seen such short and round eyebrows but they perfectly match him. He look like a nobility from his clothing. They first thought that he must be from noble family not a shinobi. But their thinking was cut short when they saw his eyes. Byakugan. No mistaking it. Those white eyes without any impurities, definitely the famous doujutsu of Hyuga clan.
Kushina couldn't feel any negative feeling from him thanks to being kyubi's jinchuriki. When she looked closely, suddenly she was surprised to feel kyubi inside her showing some emotion other than hatred. She for the first time felt such emotion from kyubi. She knows that kyubi could see what she's looking. So that means, this boy may have some connection to kyubi. She became interested in him. After 10 years of becoming jinchuriki, she knows that the nine tail fox is very old and he may know something about the boy.
Minato on the other hand could see the sadness and yearning from his eyes as the boy watched the moon. Minato looked at Kushina, only to find her looking at the boy with great interest. When she felt his gaze, she nodded. Both jumped near the boy, startling him.
Ren, who was immersed in thinking a plan on how to save his mother, looked fiercely towards the source of sound. Subconsciously he opened his Rinne Sharingan to escape to gravity dimension, only to find out one blond young man with blue eyes and another red haired young girl. He was surprised by his luck to be found out by the parents of his favorite character. In front of him stood Namikaze Minato and Uzumaki Kushina in their jonin attire. Both of them curiously looked at him. They both got very surprised when they saw his third eye. He quickly shut down his eye and watched them silently waiting for them to start conversion.
Little did Ren knew, when they saw his third eye, they were dumbstruck. Nine tail inside Kushina, started getting agitated and roared loudly. Kushina was shocked to feel nine tail's reaction. She knew that nine tail must know something. So, Kushina came forward and asked
"Who are you? What is name?"
Minato was surprised to see Kushina starting the conversation. As far as he knew, this must be the first time she did such to a total stranger. Instantly his curiosity increased again. First the space fluctuation. Second the third eye which looked like sharingan and lastly Kushina's behavior. He could feel that the boy was struggling to answer. So he decided to break it.
"How about we return to our cave and continue the conversation."
Ren instantly relaxed. He was confused if he should tell him the truth. They already have seen his most gaurded secret. Even if he didn't tell them, nine tails would tell his origin or they could just look around old records and found some clues. They both are trustworthy. He knows from the anime about their deeds. He held great respect towards them because he knew he wouldn't do the same if he was at the same situation. Giving up their lives for the village without any hesitation, is not everyone's cup of tea. So he decided to tell them the truth. In this way he can save them from their tragic fate and Naruto would get what he always wanted. He already had determined to change the history for the best.
The trio walked silently, all immersed in their own thought. Slowly they reached the cave where Minato and Kushina were resting. Ren asked Minato to set up barrier so they won't get disturbed during their conversation. Minato was already thinking about it. He could vaguely guess that what they are going know will most likely change their lives. So he set multiple barriers for enemy detection, sound isolation and defense. After completing everything, he towards the bonfire and sat beside Kushina. In front of them Ren began the talk.
"Ok. First of all my name is Otsutsuki Ren. I am different from normal humans. Let just say that my clan lives in other dimension. You can say that Sage of Six Paths is a descendant of Otsutsuki clan."
Minato suddenly cut in "Then that means Sage of Six Paths name is Otsutsuki."
"Yes his name is Otsutsuki Hagoromo. He has a twin younger brother Otsutsuki Hamura. Their mother's name is Princess Otsutsuki Kaguya."
Minato suspiciously asked "Why do you know all of them so clearly?"
Ren smiled at his question. He didn't want to tell them who he really is beacuse they would not completely believe him. He thought of a way to make them believe but this need their consent.
"Well before answering that, I want to bring someone to our conversation, who will make you believe my words."
They both got confused and asked "Who?"
Ren smiled and said "Nine Tails or his true name 'Kurama'."
