~3rd Person POV (with Prompto)~

"So... we're looking for someone named (Y/n)?" Prompto asked. "Yes. We got information saying she's here, in Radiant Garden," Ignis replied. Noctis sighed as he looked around the new world. "Do we know what she looks like?" The prince asked. Gladiolus shook his head. "We only know a name. Let's start asking around for her."

They all followed Gladio's idea and asked around. They ran into young boys named Lea and Isa.
"(Y/n)? Yeah, she was just here. All I can remember is her saying something about 'Unversed' and ran off," the boy with red hair, Lea, said. Isa just stood in silence as his friend answered the question. Ignis thanked them and they continued their search for the mysterious girl.

After a few hours had passed by, they all rested for awhile. "It would be more helpful if we knew what she looked like," Prompto whined. Noctis nodded in agreement with the blonde. Minutes pass and a figure catches their attention. A girl with (h/c) hair and (e/c) eyes ran past them in a hurry. Prompto was the first to react and hopped up from where he was sitting. "Hey!" He shouts after the girl. She must've not heard him because she kept running. While she was running, something fell to the ground. Prompto ran over and picked up the object she dropped.

"What is it, Prom?" Noctis asked. Prompto showed his friends what he had picked up. "Did that girl drop it?" Gladio's asked. Prompto nodded and examined the object closely. It resembled that of a star. Prompto clutched the object tightly in his hand and ran off after the girl. "Prom!" Noctis shouts. He ignores his best friend and continues to chase after the girl.

~(Y/n)'s POV~

"There it is." I spotted the Unverse land close by. I ran to where I saw it. It had landed in a small alley. Luckily, no one was around. I summoned my Keyblade as the Unversed assembled itself to form an even bigger enemy.

I took out the legs and arms first with ease. Finally, the head. It kept spinning around and bouncing off walls. I aimed my Keyblade at it and casted Fira. It stopped spinning and I was able to deliver the finishing blow with my Keyblade. I sigh in relief as it vanishes into thin air. My hand automatically traveled to where my wayfinder was. "It's not there!"

I look around to see if I dropped it during the battle. "Aqua gave that to me!" I search frantically around for it but no luck. I crashed to my knees in despair. "I can't believe I lost it..." I mumble sadly. Suddenly a boy with blonde hair appears, gasping for air. He was with a group of people I passed earlier. "Um, you dropped this," he said and held out his hand. He had found my wayfinder. I quickly stood up and ran over to him.

"Thank you so much!" I take my wayfinder and notice the string around it had come undone. It must've fallen off when I was running through town. I tied it back around my neck and thanked the boy once again. "Could I ask you something?" He asked. I nodded with a smile. "Do you know a girl named (Y/n)?"

"Oh, you must be the group that Mickey was talking about. I'm (Y/n). Sorry to have rushed off earlier."

"I'm Prompto. Just call me Prom," he greeted. The other part of his group came running a few minutes later. "Prom, don't run off like that," a boy with raven hair scolded. "Guys, I found (Y/n)!" Prompto cheers. "A pleasure," a man with glasses said.

They all introduced themselves one by one while Prompto just stood next to me with a goofy grin. "We heard you can travel from world to world," Gladio said. I nodded to confirm the rumor. "All Keyblade masters can. There's just one more thing I need to take care of before I take you all to a different world."

I headed back to town square. A dark presence filled the air and I knew exactly who it was. I summoned my Keyblade and prepared for battle. "Vanitas," I growl his name. He steps out of the shadows and begins to clap. "Bravo," he said. Even though he was wearing a mask, I knew he was smirking. "Y'know, I haven't congratulated you for defeating the Unversed all by yourself. So... congratulations."

Vanitas approached me slowly. I heard the others summon their weapons. Before Prompto could approach him, I blocked his way with my Keyblade. "This is my fight, not yours."

"But-"

"Prom," Noctis spoke up. Prompto reluctantly stood down with his friends. "Are you sure you don't want help?" Vanitas taunted. I smirked back at him. "Trust me, I don't need help defeating someone like you." He scoffed and summoned his own Keyblade. "You're gonna regret not asking for help," he laughed.

Our Keyblades clashed together. Vanitas and I jumped back to get away from each other. He ran towards me and used his body double to confuse me. "Aero!" A swirl of wind caught both Vanitas and his double. His double vanished and I concentrated on the real Vanitas. "You're pretty good. Much better than Ventus," he said as our Keyblades clashed once more. "So, what Mickey said was true. You attacked Ventus and tried to kill him," I growl.

Vanitas scoffed and was suddenly above me. I cartwheeled out of the way and knocked him back. "Fira!" Vanitas flew back and slammed into the side of a building. His body fell and didn't move. Vanitas' Keyblade fell from his hands and landed next to him. I went to approach him, but Prompto grabbed my hand. "(Y/n), it's too dangerous."

"Trust me, Prom." I stared into his blues eyes with my (e/c) ones. He let my hand go, slowly. I approach Vanitas with a tight grip on my Keyblade. Once I was close enough, he began to laugh. I take a few steps away from him and prepare myself for another battle. "Good job, (Y/n). I'll keep you around... for a little while longer." Vanitas stood up and disappeared into a portal.

I dispel my Keyblade and stare at my wayfinder. "I hope the three of you are safe." I clutch it tightly in my hands, remembering when Aqua gave Terra, Ventus, and I the wayfinders she made on that starry night. I felt a hand on my shoulder and saw it belonged to Prompto. "Are you okay?" He asked.

I nodded and smiled to reassure him. "Yeah, just... a little tired." Prompto's hand tightened and I knew he was worried about me. He turned to the others and suggested they spend the night here. "Yes,
(Y/n) is tired. It would be rude of us to ask her when she is worn out," Ignis stated. Gladio crossed his arms with a smile. "Yeah. I never expected such a small girl to have so much power."

"Hey..." I growl lowly. Noctis elbows Gladio on the arm. He only laughed at Noctis' attempt to faze him. "Merlin will be able to help you find a place to stay. I... need to go clear my head."

"(Y/n)..." I walk pass Prompto to head to the Fountain Court. Once I arrived, I took off my shoes and dipped my feet in the cool water. It soothed my wary body but not my worried heart. I bring my knees up to my chest and rest my head on them. I closed my tired eyes for a few minutes. When I opened them, I was met with pure blue eyes.

I gasp and fall into the water. "I'm so sorry, (Y/n)! I didn't mean to scare you." Prompto helped me out of the fountain. I wrung my hair out and ran my hands through the (h/c) strands. "Don't worry about it, Prom. I kinda needed that."

Prompto laughed at my comment. I used a small amount of aero magic to dry my whole body. "If you don't mind me asking... who was that?" Prompto asked. I sat down on a nearby bench and patted the spot next to me. Prompto smiled and gladly took the seat. I told him about how Vanitas and Xehanort were working together. I even ended up telling him about Ventus, Terra, and Aqua.

"I'm sorry. I've been rambling for the past hour," I said to him. Prompto shook his head with a smile. "Don't worry about it. It was... refreshing." I was confused at what he meant. How could my story be refreshing? I tilted my head to the side and looked at him. His face began to turn red for some strange reason. "W-what?" He stammered.

"Refreshing?" I question. Prompto nods slowly.
"Y-yeah. It's a completely different story than ours." Prompto then began to tell me about him, Noctis, Gladio, and Ignis. Turns out, hearing someone else's story is refreshing. "Thank you, Prom." Now he was the one who was confused. "For what?"

"You're right. It is refreshing to hear someone else's story." Prompto and I stood from the bench. "You should get some rest. I'll show you to Merlin's house. I hope the others were able to find him." Prompto nodded and I took him to Merlin's house.

The others had made it with help from Scrooge McDuck. Prompto and I were still outside, talking to one another. His friends were inside, enjoying some rest and relaxation. "You should get some rest. I'll see you tomorrow, Prom." He smiled goofily at me.

"Yeah, I'll see you tomorrow, (Y/n). Just... be careful." I smiled back to reassure his worried thoughts. "Don't worry," I said and kissed him on the cheek. "Good night, Prom."
