The year is 2015. The popular card game 'Yu-Gi-Oh!' is now played by thousands of people around the world. The game itself has now become high tech. In a Duel , the cards on the field are now holographic projections that comes out out of the cards. The people who play Yu-Gi-Oh! are called 'Duelists'. This is the tale of one Duelist , and his life will no longer be the same.

(OPENING THEME: BREAK IT BY MAMORU MIYANO)

"Now , I shall use my Stardust Dragon to attack your Junk Syncron!" said a brown skinned teen with glasses. His dragon , Stardust Dragon , burned the other Duelist's Junk Syncron. "No! My Junk Syncron!" cried out the other Duelist. "Now , to finish you off! Blackwing Darkrage Dragon , attack him directly!" Blackwing Darkrage Dragon obeyed his master's command and shot a black and gold fireball directly at the other Duelist. "Game over."

WINNER: SEAN HARADA

"Aw man! I lost..." The other Duelist said sadly. The brown skinned teenager , now known as Sean , went up to the boy and patted his shoulder. "Hey , kid. You're pretty good." He smiles brightly. "You just need to practice a liitle more , okay?" The boy smiled at Sean and said , "Thanks mister. By the way , what's your name?" "My name? Its Sean. Harada Sean." Sean knelt down in front of the boy and pulled a card out of his pocket. "Take this. Think of it as a gift. I got to go. See ya later , kid." He left out the Dueling Arena and got on his back. "Now , what time is it- Oh crap! I'm late for school!" He started to peddle as fast as he can to get to his destination.

Meanwhile , at Kanogawa High School , A girl with green-blueish hair and Latino boy were waiting outside in the school hallway. "Yeesh...where the hell is Sean!?" Said the Latino boy. "It'll be alright. After all , Sean-kun isn't the type to be late for school." Said the green-haired girl. As they were waiting for Sean to come , our hero came into the hallway , panting heavily. "Hey guys...*pant*...I'm here." The green-haired girl ran to Sean and gave him a hug. "Sean-kun , are you ok?" the girl asked worriedly. "Yeah , Kayla-chan. I'm okay." The green-haired girl , known as Kayla , smiles happily. "That's great to hear , Sean-kun." The Latino boy looks at Sean. "Oi puto , you wanna go hang out at the Card Shop later after school?" "Sure , Miguel." The Latino boy , known as Miguel, smirked a bit. "I hope you're ready to get your ass kicked today , Sean." "Heh , we'll see about that." After a bit of chatting , the three friends left to go either their classes or lockers. While at his locker , Sean was getting his books , getting ready to go to his class , until he sees a object that looked like a belt buckle. He puts down his books and picks up the weird looking buckle. "What is this thing...?" The strange buckle looked like a PSP with a card holder beside it. 'Hmm...I might look at it later...'

As he was walking in the park , he was looking at the cards that were beside the buckle from before. "Gaia Blade...Gaia Buster...Flaming Fist...Man , what kinda cards are these...? I know for sure that they are not Yu-Gi-Oh cards." He looks up and saw that the sun was setting. "Hmm , guess I should go home-" "KYAAAAAAA!" He stops walking and turned around. "What the fuck?" 'Wait...that was a scream just now...that sounded like...' His eyes widened. "Oh shit! Kayla!" He began to run , searching around to find his friend.

Nearby the park , Kayla was on the ground , holding her arm as it was bleeding from a wound. In front of her was a monster with long razor sharp claws , a green tortoise armored body and a goat's head. (Think of Hase's Inves form from Kamen Rider Gaim) "S-someone...please...save me..." Kayla was whimpering terrified as the monster came towards her. The monster roared as it raised up its claws , about to strike its prey. "NOOOO!" She closed her eyes , screaming in terror as she shieled herself from the oncoming attack. "Don't you dare hurt my friend!" Just when she opened her eyes , She saw Sean fighting off the monster. "S-Sean...kun..." Sean kicked the monster back and roundhoused kicked it. "Kayla! Are you ok?!" He ran towards Kayla and saw her arm bleeding. "Your arm..." "I'm fine , Sean-kun...but , what about that monster?" Sean looked back and saw the monster growling at them. "Kayla...I need to run and hide." Kayla looked up at him , scared. "B-but , Sean-kun! What about you? I don't want you to get hurt! I can't...I can't-" "Kayla , I'll be fine. I need you to go. NOW." Kayla looked at Sean , tears brimming in eyes and nods. "Please...don't die..." She got up and ran away to a safe distance , away from Sean and the monster. Sean cracked his knuckles and positioned himself in a kickboxing stance. "Alright you son of a bitch...come on!" The monster roars and charges towards Sean. Sean kicks the monster and punches it multiple times , but the monster headbutts him and kicks him back. "Gah!" He holds his side as the monster comes closer to him. 'Damn it...If I don't do something , I'm going to get myself killed! Wait...oh yeah! That belt buckle from before!" He pulled out the PSP-like belt buckle from before. "This thing looks like those belts from Kamen Rider...maybe..." He places the belt buckle in the center of his waist. A silver belt wraps around his waist as the belt buckle flashes on. [NEXUS DRIVER!] A red light appeared in Sean's hand as a card with a design of a red Japanese dragon appears in his hand. "Woah...what should I do now..." He held the left side of the now known Nexus Driver and pushes it up that a slot appears as he place the card in the slot. [RIDER CARD!] He heard a standby noise coming from the Driver. The monster tilted its head. "Do...do I push this down?" He pushes the slot down as the screen of the Driver flashes red. [LETS RIDE: GAIA!] Above his head and around his legs , a circle of red cards appears and spins around him as his body becomes a black spandex suit. Red armor soon appears and attaches on him. He felt his face and body and looked at his body and was shocked by his new transformation. "Holy...shit...what the hell just happened to me?" The monster growled and roared , its razor sharp claws glowing green. It sends a giant green wave towards Sean but he rolls out of the way. "Whew...that was close..." He looks at the monster and rans towards it. He punched and punched the monster as it staggered back. He kicked the monster as it tried to attack him again , but this time , it froze and broke into glass pieces. Sean looked puzzled but looked around. "That was weird..." He took off the Nexus Driver as he armor and spandex disappears. [GAME OVER]. He looked at the Nexus Driver and the Red card in his other hand. "Nexus Driver , huh...?" He puts up the Nexus Driver and card in the pocket of his red jacket as he began to look for Kayla.

Meanwhile , at a unknown location , a man in a lab coat had a card with a lion design in his hand. On a lab table on his wall was decks full of cards called Nexus Cards was beside a row full of Nexus Drivers. "Soon...soon the battle will begin..."

[NEXT TIME ON KAMEN RIDER GAIA!]

"You know , Sean-kun , with that Nexus thingy , you can protect a lot of people with it."

"I...am a protector of the people! I am Kamen Rider Gaia!"
