Hello friends! This is my third fanfic. A cross-over of Naruto and Log Horizon. Well, I made this fanfic because I have no idea how to continue the other two stories. But don't worry! I will continue the Naruto x Azumanga Daioh fanfic, and maybe the Naruto x Love Plus fanfic too. Anyway, this is just the prologue. The real story begins in chapter 2!

Disclaimer: I do not own Naruto and Log Horizon. They belong to their respective owners.

Chapter 1: Prologue

"Naotsugu, Chief Nyanta, do you remember that boy?"

There were 4 person sitting in front of a fireplace. This group of people is a guild that known as Log Horizon.

A man who looked like a scholarly man with glasses was asking his two friends, a tall man who had a boyish grin in his adult face, and a cat that standing like a human.

"What is it, Shiroe-cchi?" The cat-person man or the were-cat, Nyanta, asked Shiroe, the man who wears glasses.

"Remember who?" The tall man, Naotsugu, asked too.

"That boy." Shiroe answered. "The boy who challenged all of us when we still in the Debauchery Tea Party."

"Oh…. That brat!" Naotsugu said with smiling. "He's always challenging us even though he's losing all times."

"My lord, my lord." A short girl with long black hair in a ponytail asked Shiroe. "Who is this "boy", my lord?"

"It's an old story, Akatsuki-san." Shiroe said. "Two years ago, when elder tales was still a game, there was a boy that challenged and declared a rivalry on Debauchery Tea Party."

"A rivalry?" Akatsuki amazed. "There was a boy declared a rivalry on the legendary party? What a brave boy."

"He was either brave or dumb." Naotsugu said. "He's an assassin like you, shrimp."

"Don't call me shrimp, Baka-sugu!"

Shiroe checked his friend list "I don't have his name on my friend list."

"What did we called him?" Naotsugu tried to remember. "Uh…. Ah, I remember! It's "The Number One Unpredictable Noisy Ninja" isn't it?"

"The number one…." Akatsuki remembered something. "I think I know him."

Shiroe surprised. "You know him, Akatsuki-san?"

"Yes my lord, he's pretty famous because of his dumbness." Akatsuki said emotionlessly, making Shiroe and Naotsugu sweatdropped.

"Yeah but it was two years ago." Naotsugu said. "Who knows what he's doing in two years, maybe he quit Elder Tales."

"You're not knowing this because you didn't play Elder Tales in two years, Naotsugu-cchi." Nyanta said. "He is really strong now, sometimes i met him when elder tales still a game."

"EEEHHH….. REALLYYY !?" Naotsugu surprised.

"I don't know this either, Chief Nyanta." Shiroe and Akatsuki looks surprised too.

"Hahaha, I'm telling you the truth." Nyanta said with smiling. "He even got a new nickname."

Shiroe get up from his seat and walked to the window, and then gazed the night sky. "I wonder if that boy was trapped in this world too."

"I wonder too." Nyanta said with holding his chin.

"What does he called now, Chief Nyanta?" Naotsugu asked Nyanta.

"The Yellow Flash." Nyanta then joining Shiroe, gazed the night sky too. "The Yellow Flash, Uzumaki Naruto."
