"Your.." Keiko stammered, "Your sister?"

Tsukiko chuckled.

"Yes." Madara nodded, "My sister."

She rose an eyebrow, "Since when did you have a sister?"

Ignoring the question, Madara turned back to his...sister, "I'll leave her to you."

Before Keiko could say anything, he disappeared into the swirl, leaving Keiko with her new sensei.

She didn't know what to feel about her. Tsukiko seemed like a nice person, and was very beautiful, but Keiko didn't like how calming she was compared to the man. This was his sister, after all.

"Are you okay?" the woman said, a look of concern on her face.

"Sorry." Keiko spoke, still processing what was happening, "I'm just-"

"Confused?" Tsukiko asked, a soft smile on her face.

She then closed her eyes, "I understand. This may be shocking to you. We have just met, after all."

Keiko wanted to speak, but no words came out. She had known exactly what Keiko was going to say.

...

Keiko sat down on the rock as Tsukiko handed her a cup of tea. The blue haired girl sat down next her, brushing a piece of hair behind her ear. Keiko looked over at her, unsure what to do or say.

"Well, drink." Tsukiko said, looking at the younger Uchiha.

Keiko, not knowing what else to do, took a sip of the tea.

"So," Tsukiko then turned to look up at the sky, putting her hands on her knees, "I believe that a thing to strengthen the bond between student and sensei is getting to know each other more."

She took another sip of the tea, This is really good.

"I'll go first, since I feel like it would be polite to let you wait until you're ready to tell me about yourself." Tsukiko stated as Keiko took another sip.

"I'm Tsukiko Uchiha. I'm the youngest sibling of Madara, and Izuna Uchiha. My husband is Tobirama, the second Hokage. Some of my likes are―"

But before she could finish, Keiko nearly choked on her tea.

"Wait, wait, wait-" she placed her cup on the rock behind her, "Who's Izuna? And Tobirama Senju? Aren't you in your twenty's?"

Tsukiko widened her eyes, then let out a small laugh.

Keiko rose an eyebrow, "What's so funny?"

"Madara hasn't told you yet, has he?" Tsukiko asked, tilting her head to the side.

"....Told me what exactly?" Keiko had a curious tone in her voice.

She then looked back up at the sky, "We're not from your timeline, dear. We're simply just relics of the past."

Keiko closed an eye, "What's that supposed to mean?"

Tsukiko looked back at her, smiling, "I used to host Rei inside of me too, did you know?"

It seemed more like a statement than an answer.

"Rei? You're confusing me. A lot." she said, opening her eye again.

"Ah," she sighed, "Madara hasn't told you a lot of things, has he? Rei is the demon inside of you."

Keiko widened her eyes and quickly stood up, things now making sense to her, "Woah- Wait- How did you know about the voice?"

You idiot. She was my original host.

"Why hello there, Rei." Tsukiko smiled, facing and talking to Keiko but at the same time, not.

"You can hear him? The voice?"

Tsukiko closed her eyes, making Keiko raise another eyebrow before falling on her bottom again, this time something other than grass. She opened her eyes, looking around the place she was it.

I'm back here again...

Keiko was sitting in what she called the non-wet water, and in front of her Tsukiko stood, looking up at the big gates.

"Rei." Tsukiko's voice came out as words, "Show yourself, dear. It's been years."

A figure of a big wolf began to walk forward from the shadows as Tsukiko smiled. Keiko watched, still on her bottom as the wolf― Rei, as Tsukiko called him, shown his glowing lilac eyes from behind the cage.

"Hello darling." she said, making Keiko sweat-drop.

Darling? she thought, hoping that no one else had heard the thought but her.

They were inside her mind after all.

"Tsukiko.." Rei whispered.

The blue haired girl tilted her head to the side, "It's been years."

The wolf banged his head on the bars, making the water move as Keiko shielded herself with her arm. The loud noise echoed for a minute or two, before finally stopping.

"WHERE DID YOU GO ALL THOSE YEARS AGO?!" he shouted, though the older woman kept a calm expression on her face, "THEY LOCKED ME UP― CHAINED ME, TORTURED ME. DO YOU KNOW HOW THAT FELT? EVERYONE BELIEVED I KILLED YOU! THAT I DID IT! AND THEY CALLED ME A MONSTER!"

Keiko covered her ears at the loud noise.

(Author here editing this, I'm crying because instead I didn't realize I put eyes instead of ears LMFAO. 😭)

Tsukiko walked up to the gate, making Rei growl.

"I'm sorry, dear.." she said, putting a hand onto the bar, "I wished I could've gone back and told them that you weren't the cause of my disappearance. It was my own fault."

He growled once more, backing up a bit. Tsukiko placed her forehead onto the bars, closing her eyes.

"You don't have to forgive me now, Rei." she said, then looked up at his eyes.

Keiko tried to process everything inside of her mind, So.. Let's rewind. Ancient lady (who isn't really ancient) waltzes into my life. Claims to know the thing in my head. Calls it 'darling'. Darling doesn't like her. BOOM! Argument. New lore. How bad can this get?
