Naruto remembered something. The girl he just has seen was the reason for Kurenai to abandon her team. When he walked around Konoha, he found Kurenai was stood on the top of the building.
Naruto: "Onee-san"
Kurenai: "Naruto-Kun"
Naruto: "I heard from Hinata about you"
Kurenai: "What?"
Naruto: "Please don't quit team 8, they're really depressed, especially Hinata-chan"
Kurenai: "So you came here for that"
Naruto: "Yeah. They really look up to you, Onee-san"
Naruto headed toward Kurenai and hugged her. he bumped into her ċhėst and put his head to Kurenai's mountains.
Naruto: "Don't leave me, onee-san"
Kurenai mumbled to herself "This rascal", but she just hugged him.
After a few minutes, Kurenai said to him "I'm sorry, Naruto-Kun". Then he released herself from his arms and ran away.
Naruto didn't follow her, because he knew the true reason about Kurenai. Moreover, the real reason Naruto came here was to hug her and affect her feeling.
Naruto headed toward Villa in Satomigaoka Hill, where the girl lived in. he watched the villa from the outside. Around it, there were some traps, moreover, the Anbu was there.
Naruto used 'transformation no Jutsu', transforming himself to Kurenai.
"Ring ring"
2 medical ninjas came out of the villa.
"Yup"
Then the Anbu came out. "An intruder?"
"Yes"
Kurenai (Naruto) headed toward them.
Anbu "Kurenai"
Naruto (Kurenai): thanks for your around the clock surveillance. Please let me visit Yakumo
Anbu: this late at night? Yakumo is resting inside
Naruto (Kurenai): Will you leave for a moment? I'd like to talk to her in private
Medical ninja 1: Yes
Naruto (Kurenai): "It'll be over in ten minutes"
Anbu: "Very well"
Naruto entered the villa, headed to Yakumo's room. Inside, he found several pictures of various horrors, including the image of Kurenai being stabbed in the heart. Seeing this picture somehow caused Naruto to become suddenly struck by an overwhelming fear as if he was stabbed and a vision of a demonic-looking Yakumo appeared.
"Kyaaaa… my heart"
Suddenly he heard Kurama "Fool… this is just genjutsu, kid"
Hearing Naruto crying, Anbu and 2 medical-ninjas came up to him.
Anbu "What's happened?"
Naruto pointed at the picture "That picture is a picture about me who was stabbed in my heart. Suddenly I was put under Yakumo's Genjutsu"
But the Anbu and medical-ninjas didn't look at the picture. They knew if they looked at the picture, they would be put under Genjutsu too.
Anbu: "Ok, now be careful"
After watching the picture, a scene about Yakumo's memory appeared on Naruto's head
He appeared inside Academy building. Then he heard a voice from the classroom. He headed to the class and found that Yakumo and Kurenai were arguing.
Yakumo "Why I can't be the ninja, Kurenai sensei? I really want to become a ninja. I must become the one"
Kurenai "I told you to give up"
Yakumo "No"
Kurenai "Then I will have no choice but to use the fuinjutsu and seal your ability"
Then he exited the world of memories. Now he knew the reason.
"Yakumo Kurama Born into the powerful Kurama clan, Yakumo inherited her family's powerful genjutsu abilities. Yakumo's able to force her target's brain to believe everything that's happening in the genjutsu is real, causing the body to manifest real injuries, and even potentially death. Despite the strength of her abilities, Yakumo's unable to use them fully—her poor health and physical weakness prevent her from employing other forms of jutsu in fighting situations. This instability led Yakumo to develop an evil personality that killed her parents and made her a significant threat to Konoha. Because of this, Kurenai sealed Yakumo's power"
Yakumo looked at Naruto. "Kurenai sensei" but when he stepped on the roof, he entered another world. The countless pictures were flying in the sky.
Yakumo took Kurenai's picture and started to create a knife on the picture. The knife was stabbed to Kurenai's body on the picture.
"Kurenai-sensei, your life is in my hand"
But Kurenai (Naruto) just smiled.
"Who are you? You are not Kurenai sensei"
Naruto released his transformation jutsu, revealing his true appearance.
"I'm Naruto Uzumaki, I want to talk with you about Kurenai-chan"
Yakumo "who are you? Why do you come here?"
"I'm Kurenai's brother"
Yakumo tried to use genjutsu, but nothing worked on Naruto. Naruto opened his eyes, revealing Sharingan at the right and Rinnegan at the left.
"Why did my power not work to you?" but when she saw his eyes, she sat on the ground while crying.
Naruto just hugged her "Don't worry about anything, I'm here to protect you. Moreover, I can release your seal."
Yakumo "Really?"
Naruto "Tell me what had happened to you" Although Naruto already knew the reason, he kept listening to her problem. The psychologist said 'listening to her problem will make a woman's heart relieved. The other said 'listening to her problems will make half the problems cured".
Yakumo hugged him and said "I born in Kurama's clan. Kurama's clan was one of Konoha's prominent powers as a genjutsu user clan. But my clan fell from power because my clan was unable to produce jounin and chuunin. Then a hopeful talent came to the clan. It was me, Yakumo Kurama.
My parents and relatives placed their hopes on me, the head family's the only daughter
But I was frail, so I was not officially admitted into the academy.
I, who wanted to live up to everyone's expectations, became very depressed.
My father saw me depressed and went to ask the Third Hokage-sama directly, and then he put me under Kurenai-sensei teaching.
But….
Ku…. Ku… Kurenai sensei … She….!
She's sealing my power.
I overhead Kurenai-sensei and the Third Hokage-sama talking.
He wanted to destroy me and my clan.
My parents died right before I started training under Kurenai-sensei. It was a sudden fire. I heard the fire spread fast, and they were unable to save them. But both of my parents were jounin. For them to die in an ordinary fire… in broad daylight too. Later, even after it was said to have been just an accident, the investigation reports were classified as top secret and sealed. My parents were killed by order of the third Hokage-sama."
Naruto just listened to everything until she stopped talking.
"Do you want to know the truth, Yakumo?"
Yakumo just nodded. Naruto put his hand on the top of Yakumo's head, putting her into genjutsu, revealing the scene where the fire engulfed her parents.
The fire was caused by Yakumo, not other persons. The demonic form of Yakumo appeared and smiled evilly when it caused the fire.
Yakumo "You…. This is not real"
Naruto "No, this is the real fact about you. My eyes can see everything, including memories. I'm just revealing your memories."
Yakumo "NOOOO"
Naruto "Yakumo, you are misunderstanding something. Kurenai-chan thought you were precious and that's why she sealed you. Kurenai-chan kept everything a secret and suffered all by herself"
Yakumo "the truth?"
Then Yakumo felt a severe headache. One of the pictures fell to the ground, revealing the truth. The demon burned her parents.
Yakumo clenched her fist "That's true. My inner self killed my parents by using genjutsu.
Yakumo took a kunai and wanted to stab her heart with it, but suddenly a hand came out from the painting and stopped her. Then the demon came out from the picture. Naruto could feel a powerful chakra came out from the demon.
"How dare a low being like human tries to change my vessel's mind? You want to make my mission fail?"
Naruto rushed toward the demon and aimed his Rasengan to the demon.
The demon was stepped back for 3 steps, but Naruto took away Yakumo from the demon.
