And last, but not least... this story will follow a Hyūga OC that falls in love with a female Uchiha named Izumi from Itachi Shinden. Wish me luck.


"Hello. My name is Mizuto Hyūga. And this is how I had fallen in love with Izumi Uchiha."

A thirteen-year-old boy by the name of Mizuto Hyūga was currently within the Uchiha Compound walking on a street within Konohagakure. Mizuto had fair masculine skin for a Hyūga, short straight black hair that goes down to the back of his neck and a pair of white Byakugan in his sockets. He had worn a long-sleeved green jacket with a hoodie attached to it, a pair of black pants and a pair of black Shinobi sandals. On his right pants sleeve is a small Shinobi pouch wrapped around his leg with white wraps.

Mizuto Hyūga was currently walking toward Izumi Uchiha's apartment inside the Uchiha Compound. He also held a small bouquet of red roses in his arms.

"Now, some of you are probably asking... "What am I doing in the Uchiha Compound in the late of night?" Well, you see... I have a personal mission. And that mission is to see a certain someone and that "certain someone" out on a date. But little did I know that the night I went to the Uchiha district, willingly... would leave a huge impact on me and those that I care about..."

Within the night sky, the full moon had shined above Konoha.

"And just, why did you drag me here, again?" Hana Inuzuka asked Mizuto while walking behind him.

"This is Hana Inuzuka. Kiba's older sister. We shared the same class together with Itachi Uchiha. We graduated from the Academy just one year after Itachi did and now we're on the same Genin Team, known as Team Five. If you're asking what kind of relationship that Hana and I have? Well... to me, Hana acts more like a sister to me. The kind of sister that teases me, constantly than a romantic interest."

A thirteen-year-old Hana Inuzuka had fair feminine skin, unlike her mother... red fang markings on her cheeks, smooth dark brown hair that goes down to the nape of her neck and circular black pupils. She had worn an orange jacket with a furry hoodie attached to it, a pair of black pants and a pair of short black Shinobi sandals.

"Because, I want to have at least one witness with me to prove to the others that I'm not crazy." Mizuto smiled while walking toward Izumi's apartment.

"Crazy? Why would anyone think you're crazy?" Hana raised her left eyebrow.

"Because. Tonight's the night when I finally step up and ask her out on a date." Mizuto confidently smiled.

"Her?" Hana asked.

Mizuto stayed silent for a moment.

Something clicked within Hana's mind and the thought made her grin. "Oh, you mean... "her." Hana had suddenly thought of Izumi Uchiha.

Mizuto smiled and thought of Izumi as he kept walking toward her apartment door.

"That's right. I have crush on Izumi Uchiha. I've always had a crush on her, since the day I saw her when we were in the Academy. That was when I was six years old. I've always been shy about it. Other than Hana... Izumi had also graduate from the Academy the same time we did. And she's also been assigned to my Genin Team."

"So, what's the occasion?" Hana grinned and asked as she placed her arms behind her back.

"Too be honest, I don't know. I just got up this morning and decided to ask her out." Mizuto answered while smiling.

"So, it finally took you six hole years to finally grow some balls, huh?" Hana chuckled.

"S-SIX HOLE YEARS? That's how long it's been?" Mizuto flinched feeling surprisedand embarrassed.

"Come on. We all knew you have a crush on Izumi. I've known it, Tōji-sensei's known it, even Izumi's crush, Itachi knows it." Hana said.

Mizuto stopped walking and hung his head down in depression. "Izumi's crush, huh?" Mizuto muttered in a depressed tone.

'Wow. Mizuto's confident in one second and he gets easily depressed the next.' Hana thought with an embarrassed smile.

Mizuto then lifted his head with new confidence and optimism. "But that doesn't matter. I'm still going to ask Izumi out, regardless whether she has a crush or not." Mizuto kept walking forward.

Hana sighed, silently. 'He still refuses to give up and move onto someone else, despite Izumi liking Itachi. That's Mizuto for ya-' Suddenly, Hana had gasped when she caught a strong whiff of in the air. 'This scent! It's...' Hana then covered her nose. 'It can't be!'

A Few Seconds Later...

As Mizuto was continuing to walk toward Izumi's apartment... he was suddenly grabbed by Hana and pinned to the wall by her.

"H-Hana? What are you do-Mmph!" But before Mizuto could finish asking, Hana quickly covered his mouth, leaving him to muffle.

"Shh," Hana said while shushing Mizuto. "Be quiet." She asked in a quiet and serious tone.

Mizuto muffled in of confusion.

After four seconds, Hana then let him go.

Mizuto breathed after Hana let him go. "What was that about?" He asked in a bit of quieter tone.

Hana turned from Mizuto and had caught another whiff of the strong smell in the air. Her nose was pointing at the sky. "Do you smell that?"

"Smell what?" Mizuto asked as he sniffed.

Hana slowly turned to Mizuto with a serious look on her face. "It's blood."

Mizuto raised his eyes in shock. "Blood?"

Hana nodded.

"But, how do you know it's blood?" Mizuto asked Hana, denying it.

"My Clan, the Inuzuka has really strong noses that rivals canines. Ive told you that, before." Hana said as she pointed at her nose.

After hearing Hana speak, Mizuto couldn't believe what she was saying. His body begun to twitch out of disbelief. Then, he started running toward Izumi's apartment. But unbeknownst to himself, Mizuto unintentionally dropped the small bouquet of red roses that he was planning to give to Izumi.

Hana gasped when he saw Mizuto running away toward Izumi's apartment. "Wait, Mizuto!" Hana tried calling, but her words fell on deaf ears. She then decided to follow Mizuto where ever he went.

A Few Seconds Later...

Mizuto and Hana had stopped at a street and witnessed dead members of the Uchiha Clan. Men, women and children lying dead on the ground, leaning on the wall and on their backs, stomachs and sides.

"W... what is all of this?" Mizuto asked in complete shock. He had never witnessed so many dead people or a crime scene in his life.

Hana Inuzuka covered her nose in disgust as she horrifyingly stared at all the dead bodies. She didn't know what to do.

"I saw all of the dead bodies and I asked myself, "What happened?" I didn't know the answer, nor did I know what caused all of this. In my mind, there was one question keep being asked repeatedly in my mind. "Where is Izumi Uchiha?"

Mizuto clinched his fists, tightly.


Meanwhile...

Itachi Uchiha was currently roaming throughout the Uchiha district and following the order that Danzō Shimura gave him. And that was the eradication of the Uchiha Clan. Excluding Sasuke Uchiha.

Itachi was wearing his Anbu Black Ops gear. He was suddenly approached by his father, Fugaku Uchiha in the middle of a road.

Fugaku's Sharingan were activated. "Itachi. Tell me, what is to come of this slaughter?" Fugaku asked, demanding to receive an answer.

Itachi activated his Mangekyō Sharingan in response to Fugaku's question. "This."


Meanwhile...

A tall Masked Man with long black spiky hair was wearing a dark blue cloak and an orange mask with black stripes on it had suddenly departed from the Police Department within the Uchiha district. He had previously slaughtered every last Uchiha within the building without a single wound. As the Masked Man was walking out, he was suddenly met by two Shuriken which he phased through with his Kamui ability. He looked to the left to see a girl with long dark brown hair, a small black mole under her right eye, a purple Uchiha outfit and a pair of three-tomoe Sharingan activated. This girl was Izumi Uchiha.

"Oh? Such fine eyes." The Masked Man had noted. Then pulled chains from his left long sleeve.

Izumi had thrown two kunai at him, which had passed through the masked man.

"Hmph." The Masked Man had smirked toward Izumi.

Izumi had then gasped when she realized her attacks did not work on him. "No. No way!" Izumi had then thought about turning and running away. But before she could retreat, she was suddenly caught in the Masked Man's chains and pulled toward him. She fell onto the ground, landing on her klft side. And when she looked up, she saw the masked man standing over her.

"I'll be taking those from you." The Masked Man said as he then begun reaching downward toward her face.

Izumi suddenly felt like crying out of feat as she felt something horrible was about to happen to her.

'Help me, Itachi! Help me!' Izumi had thought as felt her life was in danger.

The Masked Man's palm was a few inches from touching her face.

Then, suddenly...

The Masked Man then sensed another presence and phased through two Shuriken thrown at him like target practice.

All of a sudden, one of the Shuriken that was thrown at the masked man had poof'd and it turns out that one of the Shuriken was a thirteen-year-old boy named Mizuto Hyūga.

'Oh? Reinforcements?' The Masked Man had thought.

'M-Mizuto!' Izumi had thought in shock as she saw Mizuto, her teammate.

"Take this!" Mizuto had thrown two more Shuriken toward the masked man's direction. One Shuriken was thrown at the masked man's face and the other Shuriken had landed near Izumi's left arm on the ground.

Izumi had gasped when she saw the Shuriken near her left arm.

The Masked Man phased through the Shuriken attack.

Mizuto quickly landed on his feet. "Let go of her!" Mizuto activated his Byakugan and yelled at the Masked Man.

'A Hyūga, eh?' The Masked Man then narrowed his right eye.

"Mizuto-kun..." Izumi muttered.

The Masked Man then stared at Mizuto, then down at Izumi. "If you want me to free this girl..." Then, the Masked glanced at Obito with his Sharingan activated. "Then, you'll have to pry her from my cold dead hands." The Masked Man said with a singular gleaming Sharingan.

"Tch!" Mizuto grunted.

"I could tell just by looking at him that he's a lot stronger than me. I honestly didn't know to free Izumi."

Suddenly, a whistle had been blown in the far distance. But it wasn't just any whistle. It was an emergency whistle calling for reinforcements.

'An emergency whistle?' The Masked Man had thought as he stared in the northwest.

Mizuto gasped as he heard the emergency whistle. 'Now's my chance!' Mizuto had pulled one last Shuriken out of his Shinobi pouch and thrown it toward the Masked Man's direction.

The Masked Man saw a Shuriken flrying toward his direction and attempted to phase. But this Shuriken had suddenly curved to the right and struck the chain he subdued Izumi with.

"What?" The Masked Man looked surprised when the chain he subdued Izumi with snapped.

"That was the moment that I had chosen to strike. Instead of worrying about how I could match that masked guy in strength, I used tactics to free Izumi from the masked guy."

Izumi had gasped when she heard the chain snap. She looked to see that she was free from the Masked Man's grasp.

"Run, Izumi! Hurry!" Mizuto yelled to his teammate.

Izumi heard Mizuto yell at her then decided to listen to Mizuto by using the Shuriken on the ground near her left arm and freeing herself from the chains around her body. And as soon as she got up on her feet, she got up and attempted to run toward her teammate. But before she could take at least five steps toward Mizuto... "Guaack!" Izumi gauged in pain at first, then collapsed onto the ground, face first.

"Izumi!" Mizuto yelled out of shock and worry.

The Masked Man had hit Izumi in the back of her neck with the hilt of his katana.

"Tch!" He grunted in front of the Masked Man. He then reached into his Shinobi pouched and discovered there were no more Shuriken to throw. 'I have nothing else to attack him with! And even if I did, I can't hit him with anything! This guy can phase through any physical matter-like some kind of ghost! And Izumi...' Mizuto thought in worry.

He then removed his sheath, then raised his right arm up in the air. He pointed the blade tip downward directly at the Uchiha crest on Izumi's back.

"No... no, you wouldn't. Please!" Mizuto begged the Masked Man not to kill Izumi.

"I'll admit. I was scared of losing Izumi, my first and only crush. I wanted Izumi to live so much that I begged the masked guy not to kill her. But my words fell on deaf ears. Or so, I thought..."

The Masked Man was preparing to stab Izumi through her heart from behind by attempting to lunge his katana into her heart.

Mizuto gasped in horror as he watched the Mask Man raises his blade in the air. "Don't kill Izumi!" He asked with orbs of water in his eyes.

"Hm," The Masked Man then begun slamming his arm downward toward Izumi's back. He did not care if she died.

"NO!" Mizuto screamed as he shut his eyes and tears bounce from his eyes.

Suddenly...

"That's enough."

The Masked Man had automatically stopped himself before his blade could pierce Izumi's back where the heart was. Those two words stopped the Masked Man from taking the unconscious Izumi's life.

"Huh?" Mizuto looked confused with tears running down his face.

The Masked Man then looked up to see someone standing on top of the Uchiha Police Department building.

Mizuto heard a masculine voice coming from above, so he decided to look up at the Uchiha Police Deportment building only to see a single Anbu Black Op agent with dark hair and gleaming red eyes. This Anbu Black Op was Itachi Uchiha. 'I-Itachi? W... what's he doing here?' His eyes widened in shock.

"We're done, here." Itachi said to the Masked Man.

"When I looked up and saw Itachi standing on top of that building, I automatically assumed that he was coming to help us. But I was totally being naive."

Mizuto listened to Itachi's words. 'Done? What does he mean by that?' He then gasped in horror. 'Wait... all those bodies I saw in the street before coming here. Could it mean that they-'

"But there's still one breathing Uchiha, left-other than the two of us." The Masked Man stood up and pointed down at Izumi. "And we also have a witness, here, who knows about us." The Masked Man then pointed his blade toward Mizuto.

Mizuto had gasped. 'Wait... Itachi and the Masked Man are killing off the Uchiha? But, why though?'

"I think it's best if we do away with them, right here and now." The Masked Man then turned toward Mizuto.

Mizuto then had taken a defensive Gentle Fist stance as he saw the Masked Man walk toward him.

"Don't bother with them." Itachi said, ordering the Masked Man to spare and ignore both Mizuto and the unconscious Izumi.

"Are you sure you want to ignore them?" The Masked Man asked Itachi.

"You heard the emergency whistle, recently. Did you not?" Itachi asked the Masked Man. "That means, the Anbu Black Ops and the Konoha Jōnin will arrive, shortly." Itachi said, turning his back around.

The Masked Man sighed. "Fine." He then activated his Kamui ability to transport himself.

Mizuto was visibly surprised when he witnessed the Masked Man use the Kamui ability to transport himself elsewhere. 'Who in the world is that guy?'

"I was shocked to see that masked guy disappear from thin air-like he was an actual living ghost. But I was more shocked about was the conversation that he and Itachi had. It's as if they were working together and caused all of this chaos."

"Mizuto." Itachi had called Mizuto's name.

Mizuto gasped, then quickly looked up at Itachi who's still standing on top of the Uchiha Police Department building after his name was called.

"Don't ever speak of this moment to anyone. Not now, not ever." Itachi had told Mizuto while Itachi's back was facing him.

"Itachi?" Mizuto had questioned Itachi's words.

"If you do..." Itachi slowly turned his head around to show Mizuto a glimpse of his Mangekyō Sharingan to Mizuto from the high ground. "Then I will not hesitate to kill you and those you love." Itachi said with in a cold tone.

Mizuto had gasped when he saw Itachi's Mangekyo Sharingan pattern. 'Those eyes... what kind of Sharingan is that?' Mizuto thought to himself, not knowing of the Mangekyō Sharingan.

"That was the first time I had ever seen a Mangekyō Sharingan. At the time, I didn't know what it was."

Itachi turned his head forward, facing elsewhere and disappeared from Mizuto's sight without wielding a single hand sign. He dashed off at top speed.

"W-wait, Itachi! Why are you doing this?" Mizuto yelled as he tried running toward Itachi's direction. But he was too slow to catch up. He stopped and stared upward. "Itachi..."

"I tried to get Itachi to answer questions on why he was doing what he was doing... I wanted to know what was going on and why the Uchiha were being slaughtered? But he just disappeared without saying a single word."

"I..."

Mizuto heard a mutter, then looked down to see an unconscious Izumi Uchiha still lying on the ground. She was a few yards from him.

"I... Ita. Chi." Izumi was muttering Itachi's name.

Mizuto sadly sighed. Then, he walked over to her and scooped her off the ground. He carried her in his arms, bridal style. He then looked up at the full moon in the night sky with a sad look on his face.

"I'm happy that Izumi is safe. But what I'm sad about... is that I think that what happened tonight is going to heavily effect her in the long run."
