The Lost Otsutsuki

Missing piece

"Come on, Akari, focus or I'll throw up." Said Hikaru covering his mouth.
"You don't look so good. You should stay in bed. I can train on my own." I suggested looking at his misery.
"Nope, I'm fine. Just a little hungover. Okay, let's try this again!"

I nodded and formed my hand signs, cutting my chakra flow, like yesterday but it didn't work. I let my arms down, devastated.
"It's not working!"
"You're not thinking. You need to concentrate."
"Well, I can't think, damn it!" I yelled at Hikaru.
"Come, sit with me." He said. I did as he told.
"I know you want to get back to your life as soon as possible, but rushing this won't do you any good. There are things in life you can't rush or force to happen. You just have to go with the flow and this is one of them. You need to accept yourself, not fight it. Discovering your powers shouldn't be a torture, it's a journey so I want you to think about that."
"Hikaru, I want her gone, the other part of me."
"That's impossible and you know that well. Stop fighting and denying, open your mind, get to know her, find yourself, Akari...That's enough for today. I want you to train your mind for now. Let your body rest."
"You're a really good teacher, you know?"
"Please, don't start calling me sensei!"
"Alright, sensei." He rolled his eyes.
"What are you, Akari, seven?!"

I was too excited to deal with my training. Didn't care about the powers or transformations, I just wanted to meet Ogen again.
As soon as the clock struck midnight I sneaked out and got to the lake.
"Hey, sis!" He called me from the forest. "Come with me!"

I followed him to the hills, racing each other on the way, like little kids. We climbed and sat on the cliff overlooking the whole valley with the moonlight shining softly on it.
"It's pretty up here." He said.
"Is this where you live?" I asked.
"I'm not from around here."
"Where exactly are you from, Ogen?"
"I live in another world, far, far from this one with our clan."
"So it's true, we are the Ōtsutsuki." I remembered how Sasuke looked at me realizing I was one of them. That disgust on his face. It was all true, Sasuke was right. Ogen smiled at me.
"Why are you saying this with such sadness in your voice? You should be proud!"
"There's nothing to be proud of when you come from a murderous clan. Not after what they did to this world. I'm never gonna accept that."
"That's Kaguyas doing. She was a traitor and got what she deserved. Doesn't mean our clan is murderous."
"People don't think like that here."
"Our mom was a human." He said all of a sudden. "Dad is from Ōtsutsuki. That makes us half-bloods."
"That explains it. Wait, did mom die?" He nodded.
"She took you and ran away when we were still kids. Dad and I spent years looking for you two. Dad gave up, but I didn't. And here I am, I finally found you." He reached to hold my hand. I smiled at him. "Dad will be so happy to see you!"
"In the other world, you mean?"
"Of course!" He said joyfully. That scared me. Why did mom run away from him in a first place?
"I don't think I'm ready for that."
"Whenever you are."

I looked at the valley again. I trusted Ogen but something about our clan seemed shady. I needed to find out one thing at a time.
"Ogen, can I ask you something?"
"Anything, sis!"
"Can you help me with my powers? I'm having a trouble controlling them. To be honest I have no idea what I'm able to do and you seem like the right person who can help me with that."

We spent the next two weeks training together. I still hadn't told Mayumi and Hikaru about him, every night I sneaked out to meet my brother and train with him. And he told me stories. I wanted him to meet my friends, but I was scared. What if they hurt him? I grew to love Ogen from the first day I met him. He was my missing piece.
It's been over a month since we left the leaf village. I lost track of time. Barely spent the days with Mayumi and Hikaru. I slept all day and trained all night with Ogen. Mayumi started to suspect something out of my weird behavior, which made me stay as far away from her as possible, trying to protect my brother from humanity.

One night, as I was about to leave, Mayumi closed the door in my face with her power. I looked back, she looked angry.
"We have to talk."
"We can talk tomorrow." I said reaching to open the door but she pulled me away. "You can't use that on me, Mayumi!" I got mad.
"I said we have to talk!"
"Fine."
"Akari, what are you doing? You haven't talked to us for days!"
"I'm training. That's why we're here." I knew my words were hurting her, I knew that what I was doing was wrong, but I was lost.
"So you don't need us anymore.. you know, I paused my life for this."
"And I'm sorry about that. You should go back to Konoha. I'll stay."
"Wait, what?! No, I made a promise.."
"Let that go already!" I raised my voice. "I'm not a kid, I don't need a babysitter!"
"Then stop acting like one!"
"I'm sorry.." I mumbled as I realized I hurt her with much worse thing than my uncontrollable powers.
"Don't you want to go back? He's waiting for you." She asked but I had no answer. I had to choose between Naruto and Ogen. How could I ever make that choice. Going back to the leaf meant losing the chance to meet my family. "I knew you'd break his heart." She said and I felt this burning pain in my chest. I hated myself even more now. "We'll leave tomorrow morning. You have time to think this through." She went to her bedroom.

I left to meet Ogen. But this pain in my chest wouldn't go away. Mayumi used to believe in me but now I've ruined it. I felt like I've ruined every relationship in my life and couldn't go back. I fell on my knees, crying.
"What's wrong, sis?" I saw Ogen coming out of the shadows, with a concerned look on his face.
"Ogen..." I mumbled and let the tears fall as he wrapped his arms around me.
"Don't cry Akari, your brother is here."

I spent that night in a cave with Ogen, laying my head on his knees as he told me beautiful stories about the moon. His voice was calm and comforting. I was traveling and seeing through his stories. But the pain...
"Ogen.." I stopped him.
"What is it, sis?"
"I'm a terrible person. I hurt the people I love. I used to think I was doing this for them, to keep them safe, but actually I'm doing this for myself, hurting them on the way. I'm selfish." I wiped my tears. "I did this to feel better about myself, to feel less of a monster. I got lost in the way... I don't think I can ever go back to the leaf. They deserve better than this., better than me."
"What are you talking about, Akari..."
"I promised him I'd go back but now I don't want to. He'll be happier without me. Ogen, I want to go home!"
"You mean..." his bright eyes widened.
"Yes, home. I want to meet dad and everyone."
