I know the prologue was pretty sucky, but it was only to introduce a character and a backstory for said character. Don't hate! Just read further before casting judgement on this fanfiction.
In a virtual world known as ALfheim Online, on the 75th floor of a floating castle of steel, seven people walked through large double doors into an empty room. The red-haired man in the back was called Klein. He was a samurai armed with a katana and a golden hammer. The girl ahead of him was Liz, a blacksmith with short, pink hair and armed with a mace. The two girls ahead of her had cat ears and tails. They were Sinon, a light blue-haired archer, and Silica, a short girl with sand-colored hair in pigtails. Beside Silica was a tiny dragon with light blue feathers. Ahead of the human/feline hybrids was Leafa, a girl with blonde hair in a ponytail, dressed in a light green dress. Asuna, the girl ahead of Leafa, had sky-blue hair and a rapier at her side. And finally, at the end of the long, somewhat poorly-written list was Kirito, Leafa's older brother. He had black hair, a black coat, and two swords on his back. One was blue with black accents, while the other was the Holy Sword Excalibur, a golden sword with three blue orbs just above the handle. As soon as the double doors closed behind the group, Kirito stopped, signaling the others to do the same. He then pointed upwards. At a first glance, the thing above may have looked like a pile of bones from dead monsters that defied gravity. Then the four-eyed skull looked down, the eyes a blazing red. The monster dropped from it's place on the ceiling, revealing a large, scorpion-like body. Four green HP bars appeared near it. The name clearly read 'Skull Reaper.' The name brought back memories for everyone, except for Sinon, Leafa, Liz, and Silica, who did not fight the creature in Sword Art Online. Klein then remembered how difficult this boss fight had been the first time around. "Uhh... Did anyone else just realized how screwed we are?" He asked, afraid. "Don't worry." Kirito reassured his best friend. "We already know all of his tricks. And if he has any new attacks, Yui will tell us." He gestured to a tiny head poking out of his jacket pocket. Yui was a little girl with black hair that Kirito and Asuna had 'adopted' in SAO. That is, before they found out she was a mental health program forced to watch those trapped in Sword Art Online slowly descend into madness. Kirito had brought her to ALO by turning her into a teardrop-shaped jewel to bring her back in ALO. She was currently even more of a little girl than before, as she took the form of a helper fairy, causing her to shrink in size. Everyone drew their weapons and prepared for the fight.
One boney ass-kicking later...
"See, Klein? Easy." Kirito said, in spite of how tired he was. "Yeah... *pant*... So easy... I had the time of my friggin' life." Klein panted out, exhausted. Round two with the Skull Reaper had been even more draining than in Sword Art. Perhaps because they would respawn after dying this time. "Is THAT what you did in SAO for two years?!" Leafa asked, amazed and tired. After catching their breaths, the group moved on towards the door. "Daddy," Yui called to Kirito from his pocket. "Something is wrong. I'm sensing another entity in this room." "Is it a player?" Kirito asked. "Or an NPC?" Yui shook her head. "Neither. I don't know exactly what it is, or where. But it kind of looks like-" Yui didn't get to finish. Her voice became garbled, and she began to spasm around. Suddenly, Liz screamed briefly before vanishing. The same happened to Sinon, Silica, Klein, Leafa, and Asuna, in that order. Kirito knew he was next, so he saw only one solution. He began a recording program he had been tinkering with. He recorded a message, put it in Yui's inventory, and used a teleport crystal on her before vanishing.
And so ends the beginning. More chapters on the way!
