The Darkness (Kingdom hearts version of The Unpure)

Chapter 1

"Where am I?" I asked out loud. I can barely see because of how dark this place is. I dug a mini flashlight out of my pocket and turned it on. I heard a screech. "Who's there?" I said as I shined the light over to where I heard that horrible screech. All I saw was a damp concrete wall.

Some thing pounced on me. Struggling frantically, I kicked whatever pounced on me off of me. I began looking for a door when I saw a boy around my age huddled in a corner of the room, sleeping. I walked up to him and crouched down. I cautiously poked him. He woke up, looking like he had seen a ghost. "What's your name?"
"My name is Ventus, just call me Ven for short" He said.
"Do you know where a way out is?" I asked.
"You have light inside your heart, you know a way out" Ven said.
"Light inside my heart?" I questioned.
"Your heart has pure light in it, not tainted by any darkness whatsoever." he said. "You wield a keyblade. You were made to save the world from the Darkness and the Unversed." That's when I get knocked out by the thing that pounced on me.

Chapter 2

I woke up to a light filled room. I sat up and rubbed my eyes. "About time you woke up!" Ven said "What's your name?"
"Alissa." I said. I saw a blue haired woman, who wore blue, black and white clothes, and a black haired man who wore black, red and yellow clothes.
"My name is Aqua" the woman said.
"My name is Terra" the man said. Aqua was carrying a Keyblade, it had a blue, silver and grey theme. Terra's had a black, grey and red theme. Ven's Keyblade had a green, gold and silver theme. I was given my sword. It was long, and had a purple, silver and white theme. I stood up and looked in a nearby mirror. I'm still in pajamas?

"Excuse me, but I need to put on a different outfit." They left me alone so I could change clothed. I first put on a purple tank top and silver baggy pants that reached below the knee. I put a black jacket that reached my ribcage over the purple tank top. I slipped on a purple and black checkered belt. My shoes were black with purple and silver straps. My ankle socks are purple and white. I finally put on a necklace with a heart shaped pendant.
