Late at night at an ordinary orphanage in the Village Hidden in The Leaves, a knock was heard on the orphanage door. A young female worker at the orphanage wakes up and sleepily and a little upset wonders about who could possibly be wanting something at the orphanage at this ungodly time of night. She opens the door and sees a sleeping baby wrapped up in a blanket with a note that just says "His name is Aomatsuna Hakuseki." Her face brightens up at the cute sleeping child, but also frowns about why someone had to abandon this cute sweet looking child with dark black hair. She takes him inside and closes the door behind her.
She starts to take the young child to a room in the orphanage. She lays him on a bed and starts to remove the blanket covering the child. The young worker almost screams and wakes the child and everyone else in the orphanage before covering her mouth. "Why does this child have a monkey's tail?! Is it some sort of kekkei genkai? Why would someone have to leave their child with a bloodline limit!? I have to tell the matron about this child!" While the young orphanage worker left to get her boss, the young monkey-tailed infant starts to slowly open his eyes. The child starts to scream in a high-pitched rage and make baby noises. "KAKAROT! THIS ISN'T OVER! I WILL TEAR YOU AND YOUR CHILDREN APART!"
The sounds of a loud baby radiating with killing intent that is so pressuring it wakes up the entire orphanage. Sounds of multiple children crying gets the orphanage staff into a rush to calm all the children down and find the source of the start of all this chaos. The original young female workers spots the tailed infant and quickly picks him up and attempts to soothe him. "Shush little baby don't say a word. Mama's gonna buy you a mocking bird..." The screaming infant stops and slowly falls back asleep. This causes all the children who were previously crying to stop and make all the workers at the orphanage to stop feeling uneasy and heavy.
"It must be his kekkei genkai that caused that pressuring and scary feeling along with his tail. I must report this to the matron as soon as possible." The female worker carries and softly and slowly pats the tailed child's back as she walks towards the matron. "Kanno-san, I have something important to say. This child was dropped off here a little while ago and is the reason for the recent craze in the orphanage. I believe it is due to his kekkei genkai. What do you think we should do?" The mature plump woman gets up and starts to walk around with a stressed look on her face. "I'm going to go tell the Hokage as soon as possible and see what he has to say about this boy. Stay here with the others."
The matron begins to run to the hokage tower. While this was happening our little tailed-infant slowly started to wake up once more. "Is this what hell is like? A blinding infuriating light constantly on your eyes?" The child opens his eyes completely and is met with the face of a young woman with a black-haired ponytail holding him. "I am being carried? What happened to me? All I remember is being sent into the sun by Kakarot and his sons. This makes no sense.." The baby is then sent off to dreamland once again.
"Yes Hokage-sama, everything I've told you is true from what I saw and heard!" The old war veteran gets up slowly.
"Well take me to him so I can see for myself." The matron tells the Hokage the location and he takes her and body flickers away to the orphanage. Once they get to the building the matron goes to find the child with the Hokage in tow. They finally see the child sleeping peacefully with his tail wrapped around the young woman's neck. As soon as the Hokage walks in the room with the child he is instantly surprised by the amount of chakra this child is holding within his body. "Is he a 10th Jinchūriki? I can't believe an infant could possibly hold that much chakra without being one. I definitely have to take this boy to the hospital and get him checked up." The young woman and matron saw the expression on the Hokage's face and they began to be worried. The Hokage noticed this and said "Oh don't be worried. There's nothing bad or wrong about the boy. It is just that I've never seen a baby with a tail before." He lies. The matron and young woman lighten up at this realization and start to laugh lightly.
"I need to take the boy to the hospital to make sure that he is completely healthy and fine while also checking out his bloodline." The young woman walks over to the Hokage and starts to hand the boy over to the old leader. When suddenly the tail around the young woman's neck begins to tighten. The matron and Hokage slightly freaks out and tries to slowly and carefully remove the tail from around her neck. The young woman is choking slightly and smiles at the monkey-like boy. Once they removed the tail from her neck the boy was carried off to the hospital by the Hokage with his Anbu in tow.
Once they reached the hospital, the Hokage got the head doctor and got into a room with the child in his arms. "Any information that leaves this room about whatever we find out about this child is considered an S-rank secret, punishable by death." The people inside the room suddenly got a heavy feeling in their chest and turned serious. "Suguro Tatsuzo take some blood from this child and tell me if there is anything unusual about it." The head doctor, Suguro Tatsuo, told his nurse to get the syringe and hold down the child while he gets the blood sample from the tailed-child.
