I just got this random idea. And remember, I DID WARN YOU THAT THERE WILL BE MORE TIFA!!!

Tifa P. O. V

I was playing with Cosmos' daughter, Y/n. Even if we were in the middle of war, and even if Y/n is to become the next goddess of this world, she still needs to know what's it like being a kid. Yuna, Laguna, Vaan and Light were talking with Cosmos. I snuck up quietly behind Y/n and...
"Gotcha!" I yelled, making her squeal in delight. Her h/l h/c locks flowing behind her as she ran. "Come back here Y/n!" I laughed as I chased her. "Tifa!" I heard Light yell. I turned around and saw her beckoning me to come forward. Y/n ran and hugged my leg. "Hey Yuna, could you look after her for a minute?" "Of course!" Yuna immediately replied. But even when she masked her happiness, I saw sadness, like she was about to cry. "Come on Y/n, let's go have fun with uncle Vaan and uncle Laguna." She smiled sweetly.

I walked up to the goddess of harmony and bowed before her. "Tifa, I need to speak with you regarding about my daughter. As you may all have memories of this place, you cant remember Y/n. She's different, she has the ability to travel around worlds and read the future and if you remember her, it could put her and your world in great risk. No one must remember her existence." Cosmos explained, near the brink of tears. "What!?" "But that's wrong!" Lightning added angrily. But Cosmos lifted her hand. "It's for the best." I couldn't believe this: I wouldn't ever remember Y/n. "I would reccomend that you spend time as much as possible with her before you all fight. All of you." We heard a sob. And we heard Vaan yelling: "Y/N! WHERE DID YOU GO!?" I turned around and saw Y/n crying.
"Y/n I-" Cosmos started. Yuna came up behind her, lifted her up and they left. We could still hear her crying and Yuna trying to calm her.

Time skip to before everyone died and went back to their worlds.

"Tifa!" I heard someone yell behind me. I turned around and saw Y/n. "What's up, Y/n." "I've hugged everyone goodbye, except for you." "Come here!" I went in and hugged her tiny body. "I'll miss y-you, Tifa." She sobbed. "I'll miss you too."

Time skip to when Y/n grew up to be a beautiful young lady and she travels worlds and Y/n P. O. V.

"So, where are we S/n (Spirit Name)?"
"No clue yet." They said.
"Wait a minute, we're back in Gaia, this this time we could see where Cloud and Sephiroth are." "Maybe." I agreed.
"Dont know about you, but I'm thirsty, so I'm gonna get something to drink." "Ohhh get some crackers please!"
I laughed.
We walked around till we found a bar. "Seventh...Heaven..? It sounds familiar..." S/n looked confused. I shook my head.
I walked in, looking in the magical wallet my 'wonderful' mother made me before she died, I have the currency used in this world.

I walked in, looking around this place seemed relaxing enough. I went up to the bar, and waited for the bartender to come and take my order. "Hello gorgeous." I turned around and saw a man walking, or should I say stumbling towards me. He looked disgusting, I mean, you could basically smell the alcohol from 1 km away. I felt him wrap an arm around me. "Why dont we *hicc* have some fun?" He smirked. I was sooo not in the mood. "Look buddy, leave me alone and no one gets hurt." He just smirked even more. "I would love to get hurt by you sweet cheeks." I groaned.

He tried to kiss me, but he crossed a line. I punched him square in the nose. It started bleeding. "You bitch!" He yelled. Just as I was about to attack him, a black haired lady came up from behind him. "I think it'll be safer if you stop teasing the ladies here in my bar, dont you agree Liam?" She kicked him out. "Thanks." I smiled gratefully. When I got the chance to actually take a closer look at her, I noticed something. "Tifa..." I muttered under my breath. She was wearing a different outfit. Not the white crop top and black skirt, no. She was wearing everything black. With a red satin ribbon on her arm. "Aerith... she's gone." I remembered.

Aerith and I met when I came here for the first time. She introduced me to Yuffie, but before she could show me more of her friends, I had to leave. We still kept in contact.

"What would you like, ma'am?" Tifa asked. Right, she doesn't remember me. (Xion vibes anyone?)
"Some water, and if you've got any crackers." "Sure."
I felt a presence beside me. "Rough day?" I asked. I saw his blonde hair and immediately knew: Cloud Strife. He merely nodded.
"Here you go, miss. Do I know you? You seem familiar." Tifa asked. "No, you shouldn't." "Uh huh. Well that'll just be five." "Sure. Here."

I looked at the water, and saw something: Sephiroth was going to burn a village in the next hour. But I couldn't tell where it is. I gasped and dropped my glass. My eyes felt tears: how could some people be so heartless? I looked up after I felt someone shaking me. I saw Cloud and Tifa looking concerned. I felt a sharp headache. "I have to go, goodbye Cloud, goodbye Tifa." I ran until I reached the doorway. "I'll miss you both, you especially, Tifa." I whispered, then ran.

Tifa P. O. V

"Do you know her, Tifa?" Cloud asked.
"No, but I feel like I did." But then I started seeing her face blurred up in my dreams, when we were in the other world. "Cloud, I think she is from the another world."
But then I started to remember more, but not all.
'Could it be...I'm starting to remember someone I should have forgotten..?'
