The Harem Jutsu

Chapter 21 Final chapter: consequences and bonds.

Kakashi and Naruto ran towards the forest. Kakashi had tracked Mizuki's scent, so they should find them pretty soon.

"Yes, I wanna save nee-chan just as much as you do, sensei," Naruto said after hearing the story, "but why do you specifically need me to go with you?"

"I was going to let her tell you this herself," Kakashi said. "But it can't be helped."

"Tell me what?" Naruto asked.

"You once said Mizuki looks exactly like that jutsu of yours, right?" Kakashi asked. Naruto nodded.

"Do you have any idea why? Or why she knew your parents so well?"

Naruto never thought about that. "So… what are you saying?" he asked.

"Her full name…" Kakashi said. He looked at Naruto. "… is Uzumaki Mizuki."

Naruto's eyes narrowed.

"She's your older sister, Naruto," Kakashi said.

"Si… Sister?!" Naruto asked.

"She already knows," Kakashi continued. "But for some reason she felt like keeping it a secret from you a little longer."

Naruto stared at him with his eyes and mouth wide-open.

"So your sister is being kidnapped by who's probably the killer we've been looking for. Does this answer your question?" Kakashi asked.

"Eh?!" Naruto yelled. "B-bu-bu-but…" He couldn't believe this.

"They're over there," Kakashi said. They hid in the bushes to come up with a strategy.

Mizuki slowly took a step back.

"You know…" Iwao said, "when I look at you, I wish I didn't have to punish you. But you know I can't let you get away with everything, right?"

Mizuki took another step back. Iwao took a better look at her. Then he grabbed her wrists and pushed her on the ground. He was almost lying on top of her.

"Damn it," he said. "I can't wait for you anymore." He started to forcefully kiss her.

Kakashi saw them. "Now, Naruto!" he said.

Naruto threw some shuuriken at Iwao. Three of them hit his right leg.

"Gahh!" Iwao screamed. "What the hell is this?!"

In a flash, Kakashi appeared and took Mizuki away.

"Are you ok?" he asked when they were further away. Mizuki was shaking, but she nodded.

"Who the hell did that?!" Iwao yelled. He couldn't stand up.

"Naruto, be careful," Kakashi said. "We don't know what his weapon is."

"I know," Naruto said. "Then let's find out." He made a hand seal. "Kage Bunshin no Jutsu!"

Four Shadow Clones appeared beside him and attacked Iwao. But Iwao couldn't dodge properly. The clones could land most of their hits.

"What the hell is this?!" one of them yelled. "Why aren't you fighting back?!"

"Naruto!" Mizuki yelled. "Stop it! He's not a ninja!"

The clones stopped attacking and the original Naruto looked at Mizuki.

"What're you talking about?!" he asked. "This guy is a killer!"

"No, he's not!" Mizuki said. "He never killed anyone!"

"What?!" Naruto asked.

"I knew I couldn't trust you now that you've been out of the house!" Iwao yelled. "You've already warned them!"

"No!" Mizuki cried.

"Why are you still trying to defend yourself from what he says?" Naruto asked.

Mizuki walked towards Iwao. The Shadow Clones disappeared.

"Mizuki!" Kakashi yelled. "What are you doing?!"

"Even after all he's done," Mizuki said, "he doesn't deserve this."

She carefully removed one of the shuuriken from Iwao's leg. Iwao clenched his teeth, but he didn't resist.

But after Mizuki had removed the last shuuriken, he took one of them, grabbed Mizuki and held the shuuriken near her throat.

"Thank you, my little angel," he said. He kissed her on the cheek.

"You…" Naruto mumbled. "You bastard! Let her go!"

"You'll only have yourself to blame if she dies," Iwao said. "I won't harm her if you let us go peacefully."

"Iwao-san," Mizuki said. "What are you doing?"

"Shut up," Iwao said. "This is your own fault."

"You don't understand… something like this…" Mizuki said.

"I told you to shut up!" Iwao said. He stabbed her upper leg with the shuuriken. Mizuki screamed in pain.

"Mizuki!" Kakashi yelled. Now that Iwao dropped his guard, it was the perfect opportunity for Kakashi to attack. Just in a flash, he appeared in front of Iwao and kicked him away.

"Naruto, get Mizuki away from here," he said.

"Right," Naruto said. He ran to Mizuki, carefully picked her up and put her down at a safe distance.

"You ok, nee-chan?" he asked.

Mizuki carefully pulled out the shuuriken. Blood was gushing out.

"Ah, so much blood…" she said. She looked away from it.

"I won't forgive you," Kakashi said to Iwao.

Iwao tried to get up. His leg was bleeding badly.

"You can't kill me," he said. "And I will get you back, Michiko! I'm gonna kill you!"

Mizuki felt cold and dizzy. She dropped herself on her back and stared into the sky.

"Nee-chan!" Naruto said. But Mizuki was mumbling something he couldn't understand. She had a blank look in her eyes.

"Snap out of it!" Naruto yelled.

The wind was getting stronger.

Kakashi took a few steps forward. Iwao tried to run away, but he couldn't. He tripped.

"Damn it!" he yelled. "I'll make you pay for what you did to my leg! It hurts like hell!"

Mizuki regained consciousness and sat straight up. She looked at Iwao.

"If you'd just stop moving around and surrender, you'll survive," Kakashi said.

Then suddenly, Iwao's leg came off! He screamed in immense pain.

Kakashi was shocked and confused. "What the…?!" he mumbled while looking around. He saw Naruto with a shocked and disgusted face and Mizuki with… no expression on her face.

"Does your leg still hurt?" she asked with that strange, low voice that Kakashi had heard before. She stood up and walked towards him. The trees she passed spontaneously fell apart.

She looked at the leg that just came off. It burst into pieces.

Iwao looked panicked. He looked at the leg and then he looked at Mizuki.

"Y-you…" he stuttered. "What the hell did you do to my leg?!"

An evil-looking smirk appeared on Mizuki's face.

The other leg came off.

"GAAAAAHHH!" Iwao screamed.

Kakashi couldn't believe it. Was Mizuki doing that?

"Mizuki?" he asked carefully. Mizuki looked at him for a second, then looked back at Iwao, who was suffering.

"'He doesn't deserve this', she said? I think you deserve even worse," she said.

"You…" Kakashi said. "You're… You're not Mizuki…"

"Confusing, isn't it?" Mizuki asked. She looked at Kakashi. She had an insane look in her eyes. "Even now, she keeps telling me not to kill you." She looked back at Iwao. "But I am gonna make you end up like that leg of yours," she said.

"W-what?" Iwao asked nervously.

"You should be glad," Mizuki said. "You don't have to suffer anymore."

Iwao looked frightened.

"Goodbye," she said with a smile. And Iwao burst into pieces. Blood was gushing everywhere. Naruto, Kakashi and Mizuki were covered in his blood. Mizuki didn't move.

Kakashi looked around. It looked exactly like one of the places where those other people were killed.

"You…" he said. "It was you."

Mizuki didn't say anything.

"W-why?" Kakashi asked.

"I never did anything wrong," Mizuki said, still without moving. "I'm ridding the world of its most sinful people."

"You've got to be kidding," Kakashi said. A few sweat drops were rolling from his forehead.

"You're sinful too, Hatake Kakashi," Mizuki said. "Even after my warning, you tried to take Mizuki, like all those other sinners did."

"What do you mean?" Kakashi asked. But then he remembered what Mizuki said to him this afternoon:

"Don't think of anything strange, Hatake Kakashi. You're ten years older than me."

"At that time…" Kakashi whispered. "That was you."

"Not completely," Mizuki said. "Mizuki and I were both only half there. She wouldn't allow me to fully come out."

"Who are you?" Kakashi asked.

"My name is Sayomi," Mizuki's alter ego answered.

"Sayomi… Why do you kill people?" Kakashi asked.

Sayomi looked at him and smirked.

"It's because of people like you that Mizuki unconsciously created me," she said. "The world is full of sin. Mizuki found that out at the age of four. She told you about the night she ran away from the orphanage, right?"

Kakashi slowly nodded.

"It was not that she created me that night," Sayomi said. "No, she just badly needed an ally who could help her after being betrayed by her 'onii-chan'. All I needed was a very weak moment in her mind. So when she was hit in the head…"

"Don't tell me…" Kakashi said.

"I only managed to scratch him on the cheek. When he saw the blood dripping from his cheek, he smacked me really hard in the head. The next thing I remembered was waking up in the middle of another forest. I was covered with blood and I still don't know how that happened."

"I killed him," Sayomi said. "It was all for Mizuki's own good. I hate to see my other self so miserable."

She went to stand right in front of him.

"Sensei, get out of there!" Naruto yelled. Kakashi looked at him, but then he just looked back at the person who used to be Mizuki.

"And now I'm standing in front of the man who caused all this," Sayomi said. "Mizuki's miserable life, my creation, all the murders… Do you even realize that?"

Kakashi was sensing danger.

"You put Mizuki under your spell," Sayomi said. "But you can't get me. I know what you are.

You'll betray her eventually. I know that. I took those thoughts from her before she even came here."

In the meantime, Mizuki could see Kakashi, but she couldn't warn him.

"Kakashi! Get out of there!"

"It's no use," Sayomi said. "He can't hear you."

"Please stop it!" Mizuki yelled. "Don't hurt him! Please!"

"Have you already forgotten what kind of life he caused you?!"

"It wasn't his fault!"

"Really? Because all of our lives, you've been telling me and yourself that it was all Kakashi's fault."

"I was wrong!"

"No, he is wrong. This is for your own good."

"No! W-wait! You don't understand."

Sayomi stared at her and walked towards her.

"The one who doesn't understand here, is you."

She embraced Mizuki.

"That man is only going to hurt you more," she said. "I don't want to see you in pain."

Mizuki didn't move.

"You're wrong," she said. "He makes me happy. And if you're going to kill him… I think you won't see me being happy ever again."

Sayomi let go of her and stared at her.

"I love him," Mizuki said.

Sayomi started to look angry.

"You love him?" she repeated. "Listen, I know how this is going to end. Trust me, the longer you stay with him, the more disappointed you will be if he'd ever betray you. It's for the best."

"No! Don't!"

"If it wasn't for him, you would've stayed in Konoha! Your life would've been normal and you wouldn't even need me!"

"I don't need you!"

Sayomi stared in her eyes and took a step back.

"You…" she said. "Fine. You say you love this man?! He won't be here for long anymore!"

"What?! Wait! Stop! I'm sorry!"

In the real world, Sayomi's eyes became darker and darker.

"Mizuki has turned against me," she said.

"What?" Kakashi asked.

"She's trying to defy me," Sayomi said. "Saying she doesn't need me. But you know what? She does. Every time again and again. And now that I'm finally completely out and take revenge for her, she turns against me! Me! Whom she created because she's too weak to defend herself!"

The wind was getting stronger again.

Kakashi jumped backwards. Now he was sure that wasn't Mizuki anymore.

"You…" Sayomi said. "IT'S ALL YOUR FAULT!"

"Kakashi-sensei!" Naruto yelled. He made another five Shadow Clones, who ran towards Sayomi. But she only seemed interested in killing Kakashi, who was dodging her attacks.

"Pull yourself together! Mizuki!" he yelled.

One of the Clones came to stand in front of Sayomi.

"Out of my way!" she yelled.

The Clone could see the look in her eyes, right before he was destroyed and disappeared.

That gave Naruto some more information. Sayomi seemed to have to concentrate at a certain point before she could destroy it. That gave him an idea.

"Sensei!" he yelled. "I think I know what to do!"

He pointed at the clones.

"You guys! Take off your forehead protectors and try to cover her eyes," he yelled.

"You!" Sayomi yelled. She looked at the original Naruto. "I told you to stay out of the way!"

But before she had a chance to do anything, Kakashi grabbed her from behind. One of the Shadow Clones managed to cover her eyes with his forehead protector and tied it to her head. Sayomi struggled and tried to get it off, but she couldn't get out of Kakashi's grip. She cursed and screamed, but it didn't help.

"Mizuki," Kakashi said calmly. "The rest is up to you."

"I'm trying," Mizuki said in the inside of her mind.

Sayomi was going crazy in rage.

"I'll KILL them! I'll kill them all, damn it!" she yelled.

"S… S-Sayomi…" she said. "Stop it."

"Shut up!"

Mizuki suddenly embraced her, which surprised Sayomi a lot. She calmed down a little.

"Enough," Mizuki said. "You've done enough. I was wrong to rely on you."

"Mizuki!" Kakashi said in the real world.

"Come on!" Naruto said. "Snap out of it! You can do it! Onee-san!"

Sayomi stopped moving.

"Did… did he just call me… 'onee-san'?" Mizuki asked inside her mind. "Did Kakashi tell him?"

"You…" Sayomi said. "You really… love these people, don't you?"

Mizuki let go of her and looked at her.

"For you to have the courage to stand up against me…" Sayomi said. "That… never happened before. You used to be scared of me."

"I still am," Mizuki said. "But… I'm even more afraid of losing Naruto or Kakashi: the only people who really care about me."

Sayomi stared at her.

"You're…" she said. "You're really… happy, aren't you?"

Mizuki nodded.

They were silent for a long time.

"Well then…" Sayomi said eventually. "Then I guess… you don't need me anymore, right?" She was getting tears in her eyes.

"I'm sorry," Mizuki said. "I've found my destination, but you…"

"It's ok," Sayomi said. "The purpose of my existence has already been fulfilled by someone else."

Mizuki knew who she meant.

"I wish you could lead your own life, as a good person," Mizuki said. " Because you are, deep inside. But I don't want to rely on my other self when I'm too weak to defend myself, either."

"I know," Sayomi said.

"Then, what should we do?" Mizuki asked.

After another long silence, Mizuki said: "We could… combine or spirits. Become one again, like we once were. Then you can enjoy life, too. Just like back then."

Sayomi stared at her and smiled.

"Really?" she asked. Mizuki nodded.

"Thank you," Sayomi said.

"Onee-san," Naruto said in the real world.

She moved a little again, but then Mizuki's voice came out: "N… Naruto?"

"Mizuki?" Kakashi asked.

"Kakashi…" Mizuki sighed. "I'm sorry."

Kakashi slowly removed the headband from her eyes, to check if they were really Mizuki's eyes again. And they were.

He let go of her and Mizuki sat straight up.

"I'm so sorry," she cried.

Kakashi held her tightly. "It wasn't your fault," he said. "It was all my fault."

"No, it wasn't," Mizuki said.

"Just… don't ever scare us like that again," Kakashi said.

While he was holding Mizuki from behind, she looked at Naruto.

"You… you just called me 'onee-san', right?" she asked.

Naruto blushed slightly and nodded.

"But… what happened to that other…?" he asked.

"She's gone," Mizuki said. "I'll probably be a little different from the way I was, but…"

"Are you sure?" Kakashi asked while letting go of her. Mizuki nodded.

"I guess I'll have a lot to explain to you guys," she said.

And suddenly, she fell back against Kakashi's chest. She fainted.

The next thing she knew, she woke up in a strange room. The Hokage was next to her bed, looking out of the window. When she noticed Mizuki was waking up, she looked at her.

"Hokage… sama," Mizuki said. She was still feeling weak.

"Welcome back," Tsunade said. "Naruto and Kakashi told me what happened in the forest."

Mizuki felt awkward. She didn't know what to say.

"See, this is hard for me," Tsunade continued. "In theory, you're the fugitive we've been looking for for fifteen years. You're a murderer and a sadist. You have some strange power we don't know about. But still…"

Mizuki got the feeling this was not going to end well for her.

"But still," Tsunade repeated, "it wasn't you. It was an evil spirit living inside you. The real Uzumaki Mizuki was always trapped."

"It was because of me that… my other self… killed all those people," Mizuki said. "It is all my fault. It was from the very beginning. I should be punished."

"Are you sure?" Tsunade asked.

Mizuki slowly nodded.

"Alright," Tsunade said. "So be it. But because it wasn't directly you who killed those people, I'll see if I can… reduce your punishment a little."

She smiled and winked before she left.

"Oh, by the way," she said, "there's someone who wants to see you."

Mizuki looked at the door, where Tsunade left and Kakashi came in.

"Hey," he said. "How are you feeling?"

Mizuki sighed deeply.

Kakashi laughed. "You must have lost a lot of energy," he said. He sat down on the edge of her bed.

"Yeah," Mizuki said.

"You've slept for four days, you know," Kakashi said.

"Four days?!" Mizuki repeated.

"Naruto's been here every day," Kakashi said. "Well… so have I, but he would stay here for hours. When I came in, he always started to ask me what you were like as a kid. And err…"

"Sensei, why didn't you tell me sooner?"

"Because she didn't want me to. She wanted to wait en get to know you better before she's tell you."

"But… in all these years, why couldn't you at least mention that I have a sister?"

"You never asked."

"… Eh?!"

"Ah never mind," Kakashi said. "Hey… could you tell me… how did Sayomi do those things?"

"Oh… that…" Mizuki mumbled. She relieved a big sigh.

"It all started when she first came out," she said. "I couldn't remember it. They were all just black-outs until I was twelve. That's when I first found out that it was me who killed all those people. That's when I met Sayomi for the first time. She told me why she did it and I believed her. But when she told me how… I couldn't believe it."

She was silent for a while.

"It took 12 years for me to find out…" she said, "… to find out that I have telekinesis."

"What?" Kakashi asked. "Are… are you kidding me? You're kidding, right?" But when he saw the serious look on her face, he knew she was serious. "B-but…"

"You saw how she destroyed everything she saw without touching it," Mizuki said. "I would never use it, though. I'm trying to forget that I have it."

"Maybe that's better for all of us," Kakashi said, though still confused about it.

"Aren't you scared of me now?" Mizuki asked. "I mean… after seeing me like that… I can totally understand of you don't want to see me anymore."

"I'm here, aren't I?" Kakashi asked. "I have to admit: seeing you like that… was one of the biggest shocks I've ever had. I was afraid I'd lost you, too. The last piece of the world I grew up in."

Mizuki smiled. "Are you sure?" she asked.

Kakashi smiled and nodded.

Just in a flash, Mizuki was holding him tightly. The fast movement made her dizzy, so she lost her grip very soon. Kakashi caught her and gently laid her back.

"I'm sorry," she said. "I'm still weak…"

"It's ok," Kakashi said. He sat closer to Mizuki.

"Mizuki…" he said.

"Yes?" Mizuki asked.

"I…" Kakashi said. "I… I love you."

Mizuki's eyes narrowed. She couldn't remember anyone ever saying that to her.

"W-what?" she asked carefully.

"I love you," Kakashi repeated.

A short silence.

"I… I love you too," Mizuki said with a slight blush on her cheeks.

Kakashi bent over, pulled down his mask and kissed her. They kissed for a long time. Until Kakashi withdrew and saw Mizuki had fallen asleep. He smiled and put his mask back on. He caressed her head and stoop up.

"Good night," he whispered. And he went home.

After Mizuki's recovery in the hospital, she had to go and see the Hokage, who had made a decision on what her punishment would be. It was quite the surprise.

"You're going to move in with Naruto," she said. "Starting today, you'll be his guardian. As his older sister, you have to take care of him. It'd be better for Naruto to get the parental love he never had. And furthermore… You work at the day care, right? Well, you're indebted to us. You work there fulltime and no days off, until you've paid back your debt. You think you can handle that?"

"Y-yes ma'am," Mizuki said.

"Good. I didn't expect anything else from Minato's kid," Tsunade said with a smile.

"I've seen you just a few times when you were little, you know. I've never been that great with kids. That's probably… why you don't remember me," she added.

Mizuki smiled.

"Your father was a great leader," Tsunade said. She looked out the window and saw Minato's face in the mountain, right next to hers. "And a great man," she said.

"I know," Mizuki said. She looked at her father's face, too. "And a great father."

It took a while for both Naruto and Mizuki to get used to the fact that Mizuki was living with Naruto. But Naruto didn't mind. Mizuki was a great cook. And she cleaned up the apartment.

Naruto often asked about their parents. He could listen to those stories forever. Even those from Kakashi. It was like they were right next to him.

That also applied to Mizuki. When she looked at Naruto, she could see her father in him.

The relationship between Kakashi and Mizuki was getting more and more serious. Mizuki wasn't afraid of being intimate with him anymore (when Naruto wasn't around). That was probably the effect of combining her spirit with Sayomi's.

At first, Naruto was a little disgusted by their relationship, since there was an age difference of ten years. But he soon found out that neither of them had a problem with that, so he slowly started to accept it. It was really strange to have his old teacher as a kind of 'brother-in-law', though. But then again, this was Kakashi. It could've been worse, he said to himself.

It was too bad Kakashi and Mizuki couldn't live together. Mizuki was still indebted and had to be Naruto's guardian until he didn't need one anymore. Of course he'd taken care of himself ever since he was little, but his life improved a lot since Mizuki started to take care of him. He wasn't alone anymore. And the family love… Well, it was strange, but for both Naruto and Mizuki, it was a great feeling. But for the first weeks, he still had to get used to calling her 'Mizuki' instead of 'nee-chan' from now on.

Mizuki became more self-confident, but she was still the nice, gentle person who worked at the day care of Konoha and made the little children laugh.

Kakashi had to go on a lot of exploring missions, but always looked forward to coming home and have some of Mizuki's great meals. He wanted to propose to her when she was old enough.

This may look like a perfect picture, but there was still one person missing. But Naruto knew he could bring him back someday. He kept training hard to make Sasuke acknowledge his existence and come back to Konoha. And he could do it. He was certain of it.

That's it. Thank you for reading this :) Please let me know what you think by sending me a message. I'd really like to know what you think about it. Thanks :D(if you enjoyed reading this fanfic check out the one I'm still working on Love triangle .
