NOTE: This is entirely based on the American anime; the Japanese would confuse me, and I know nothing about the first season.

ADDITIONAL INFO: Akari means light in Japanese. I chose that name because Akari is often a direct counterpart to Yugi/Yami, and Yami is Japanese for darkness. Also, the Eye of Horus is different from the Eye of Anubis, which is on most Millenium Items.

It was early morning, and Yugi Moto was ready for another intense day at Kaiba's Battle City Tournament... if he could just get this knot undone...
Yugi glanced at the clock. Joey and Tea would be here any minute, but his shoelace was not cooperating with his schedule. As though in response to his worries, the small, chime-like bells attached to the door rung and someone walked in.
"Oh!" said Yugi. "Tea and Joey must be here." Abandoning his shoelace, Yugi hurried downstairs, hoping not to embarrass himself. But as he approached, he heard his Grandpa speaking in the inviting tone he reserved for potential customers.
"Can I help you, sir?"
"I am looking for someone, not shopping." The voice that spoke was deep and cold, yet soft. "But, while I am in such a fine card establishment, that card looks useful."
As Yugi walked in, he saw the boy speaking to his grandfather. Not much taller than Yugi, this boy wore a loose white T-shirt and baggy black pants-not to mention a KaibaCorp Duel Disk. But what caught Yugi's attention was this boy's face. It reminded him quite a bit of a face he saw often... indeed, every time he looked in the mirror!
This boy's face and hair were shaped much like Yugi's, though a bit sharper. His hair was pure white, with jagged black bangs sticking out everywhere. His eyes were a sharp piercing blue. And his skin was dark, Egyptian.
Yugi was shaken out of his thoughts by his grandpa's energetic reply to the boy. "Ah, very good, sir. Out of curiousity, who are you looking for? I might be able to help you."
The boy shrugged. "I don't know for sure who it is... I seek he who bears the Millenium Puzzle..."
Yugi cried out in alarm. Yet another person was after his puzzle! unfortunately, crying out drew the other boy's attention. He turned to Yugi, startled. Then his eyes fell on the Millenium Puzzle, and he smiled slightly.
"So," said the stranger, "it is you who has the Item. I thought it would be a customer. You are Yugi Moto, champion of the Duelist Kingdom, am I right?"
Yugi gulped, then summoned up his courage. He couldn't, and shouldn't hide from this jerk. "Yes, that's right," he said firmly "And you are?"
The other boy bowed slightly. "I am Akari, the Vengeant. I have been chosen to avenge the wrongs that mighty Duelists can do. You have caused enough suffering, Yugi Moto, and now it's your turn to feel my wrath. Prepare to duel for your puzzle!"
Yugi blinked, surprised. "Wait! I haven't done anything wrong! What suffering are you talking about?"
"Don't play innocent with me," Akari said coldly. He glared at Yugi. "Two people, both with their minds shattered, with only one memory left to them: a young man with the Millenium Puzzle. Now, will you duel, or are you a coward!?"
Yugi understood now. During the time he had owned the Millenium Puzzle, Yami had crushed the minds of several people, though all of them had deserved exactly what they got.
I guess I'll just have to prove that to him, he thought.
