Spirit Space X
Since the high-tech develops so fast in 26 century, people are not interest in all the games. By a occasional opportunity, scientists find out that inside human's body, there is a kind of substance. We just need to inject a little incident, there will engender a very strong critter. The discovery begat the attention all over the world, but they have a big problem: they have no idea how to take out those critters. Finally, at the beginning of 2510,Seto Kaiba manufactures a kind of data switchover machine. It can show the critter inside our body. This invention stirs the whole world! All the game players went to buy this mini machine. But this game has a big fatalness: because the monsters were taken out from our body, if the monsters are destroyed, their masters will be dead soon. 2 years has past. At last, U.N agreed that the game players could play this game, because they want to make a great monster army. Since that year, Seto Kaiba always make a Duel Monster Match once a year. The winner can get everything he wants; money, honors, even human's life. They gave the game a name--Spirit Space X, and our story happened at that background...

2515. Japan. Domino City. 11:27 p.m.
"Hey! Jack! Give that little kid a deadliness attack!"
"You! Kid! Why don't you call your monster?"
...
In the middle of the duel ground, stands a very strong man, his name is Jack, and he's good at playing Spirit Space X. His monster was a level20 Dark Sword Man. Towards him, is a little boy. Looks like he's only 16 to 17,wearing black Western-style clothes.
"Hey, kid, when can you stop evading? Don't you have your monster?"
"You just shut up! I'm not calling him because I don't want to hurt you." That boy has a short red hair, good-looking face, and his eyes look so cold.
"Ok then. My Dark Sword Man! Attack him now!"
With Jack's order, Dark Sword Man runs to that boy. But the boy just jumps to the left to evade that attack. But suddenly, Dark Sword Man stopped attacking his front and turns his sword to his left.
"Ouch!" The sword hurts his left leg. He stands all by his right leg. That hurt makes him can't move.
"Ok, kid. I will finish you off next turn. You will be dead." Said Jack with a evil laughing.
"You made me angry Jack, you will pay for it." with these words, that boy takes out a small diskette which has the data of his own monster, and put it into the mini switchover machine.
"Too late, KID! Dark Sword Man, Kill that kid now!!!"
Dark Sword Man uses his special power: 12 swords fly to that boy. Even he can move, he will be badly hurt, too. But there comes a shadow beside that boy, and Dark Sword Man's attack was destroyed.
"What...what's that? What's inside those evil shadow?" said Jack with a shiver voice.
"It's my monster, the god of Osiris. Now my dragon, attack that Dark Sword Man with your thunderclap fire!"
A white light comes out from the shadow, and Dark Sword Man was destroyed.
"How, how could it be...how come a human has those strong monster?"
"It's not a monster, it's deity, the god of Osiris." the boy points at Jack, speak with a evil laughing" I want you...to be die!"
"No, Please, please don't.no.NO!!!!!"
