"But, Heartless don't exist! It's all a game!" I practically screamed in my flustered state, though not moving my body, focused on the monster.
"Try telling him that…" Sam said, ready to swing her club, hopping on the spot.
"Kingdom Hearts is real! This is so cool!" Pippa said, twirling the bat in her hand.
"It's all real. These things are the monsters that killed all those people." Alice said. The Savage Heart took a step closer to me.
"But, this can't be! This must be another of my dreams... It can't be real! …Oh god, could this have been what my dreams meant?" I said, mostly to myself. The Savage Heart took another step forward. I looked it eye-to-eye (just, it was slightly taller than me, about 6"10 at a slouch). A smile seemed to appear on its face. I prodded it with my sword and it stepped back. The smile turned to an angry stare, a growl building up in its throat.

Alice fired a round into its chest causing it to recoil. In anger, it hopped towards her and was going to swipe at her, so I held the button on the back of Persephone, de-coupling the blade and invoking its whip-like state. I managed to wrap it around its arm and pulled it backward, somehow stopping him. It looked at the blade, then at me, smiling.

"Shit." I muttered to myself, turning my leg inward a little to plant it.

Suddenly, it swung its arm across itself, sending me flying towards it. With as much agility as I could muster, I twisted in mid-air so I landed on the shoulder of the beast. Releasing the de-coupler button on Persephone, causing the blade to reform, I used it's head as a springboard and leapt away from it. Unfortunately, I landed on one knee, slowing me down as I nursed it with curses under my breath. Seeing the weakness, the Savage Heart ran towards me.

Pippa and Sam struck it in the face with their weapons, but the bat broke and the golf club bent in half with very little damage to the monster, though it had stopped in their tracks. They looked at their now useless weaponry, then at each other. Sam nodded as they threw their weapons aside and Pippa jumped out of the way. Sam held her hand out with her palm facing the Savage Heart. She spoke some seemingly random words in a foreign tongue, causing a ball of flame to fire from her hand, hitting the monster in the gut and sending it to the floor with a thudding skid, narrowly missing Alice. It tried to get back up, so I jumped on him, ran to its head and stabbed him in the side of the neck. It twitched, and then stopped. I pulled the weapon out of the thick skin and returned Persephone to its normal state. The Savage Heart slowly disappeared, and I breathed a sigh of relief.

"Okay, it's really happening… So, what happened? Why didn't we get attacked by the Heartless like all those other planets?" I asked Alice, in shock, flopping to the ground and sitting down.
"I'll tell you all I know." Alice replied.

14 years ago, the leaders of The Circle, The Four, received a message. It was stamped with the logo of Mickey Mouse. Inside, it told them of an immense evil preparing to invade and destroy Earth…
Of course, half of that you'd have already guessed. But Earth, Mickey informed them, had a get-out-of-the-shit-free card, apart from the keyhole. There was something else…

A young orphan, quite like Gabriel, had the power. No one knew who he was, where he originally came from, just where he could be found. He had the power to prevent the door being opened at the other side. It was written in his D.N.A., it was in his blood. He was taken and his blood was used to seal the door. They blocked up the entrance to the door's location and erased the Orphan's memory of the event. Although the whole World Linking thing bypassed us, thanks to The Four, Mickey had asked them to make Earth aware of the fate that nearly befell them.

The four deemed it would be a whole lot easier if it was done quietly and covertly, so they paid a visit to Square-Soft Headquarters, and, a few planted ideas later, Kingdom Hearts was born…

Unfortunately, a year and a half later, 8 years ago, the door was opened on this side…

"Gabriel…" I said, thinking out loud. Alice nodded.
"The door is in the boiler room, isn't it?" Pippa asked.
"Yes, and he went through it, setting off this whole chain of events." Alice said. Suddenly, the banging on the boiler room door started again, quicker and harder than before. The door started to crumble and buckle.
"Shit, they're coming through!!!" Sam shouted.
