The following day , at Kanogawa High School...

"Uhh...my fucking head..." Sean was at his first block , holding his head in pain. "This fucking headache is killing me...Teacher , can I go to the doctor's office?"

In the doctor's office , Sean was sitting in a chair , holding his head , hearing the doctor coming in. "Ohhhh..."

"Ah , Mr.Harada. How are you today?"

"I feel like crap and I have a bad headache. Do you have some medicine , doc?" Sean says , rubbing his head.

"Yeah , I have some asprin that you can take." The doctor grabs a bottle of Asprin and hands Sean a pill , seeing him swallow it and take a sip a water.

"Thanks , doc." Sean said , slightly smiling as he got up. "By the way , are you a new doctor here? I've never seen you before."

"You could say that , Harada." The doctor said as he looked at Sean , holding a card in his hand.

Sean looked at the card , seeing a lime green samurai on it with 'GETSUGA' in bold. There's no fucking way...the man thats been fighting him and wanting to kill him is standing right in front of him!

"...No way..."

(BREAK IT by Mamoru Miyano plays)

"You motherfucker!!" Sean grabs the doctor and pins him to the wall , anger in his eyes. "It was you!? THIS WHOLE FUCKING TIME!?"

"Mr. Harada , calm d-"

"SHUT THE FUCK UP!" Sean throws a hook to the doctor's jaw but he steps back and grabs his fist.

"Calm.Down." The doctor said in a calm , but dangerous tone. "Sit down and I'll talk."

Sean glared at the man as he sits back in his chair as the man leaned back on the wall , his arms crossed as he looked at Sean with a calm expression.

"Okay , so who the hell are you?" Sean said , anger still in his voice.

"My name is Ryūtaro. Sakaguchi Ryūtaro."

"Why are you after me? And don't tell me its just to see how strong I am. I know that's not it."

Ryūtaro sighed as he grabbed a cup of coffee beside his computer. "Think of this as a game. There are Riders , the ones who fight for their desires. And then there's the Carddroids. The ones that we are supposed to defeat."

"Woah , woah , hold up. What do you mean this is all a game? So you're saying I'm a fucking play toy to someone who's behind all of this?!"

"Not exactly." Ryūtaro takes a sip of his coffee as he starts to speak again. "The real threat that you have to worry about is the Riders , not the Carddroids."

The real threat is the Riders? What did he mean?

Robert and Miguel were playing Street Fighter V in the arcade room in school as Cameron , Ana , and Kayla were watching Miguel getting his ass kicked.

"K.O.!"

"Son of a bitch!" Miguel yelled as he was defeated by Robert.

"Dang , Miguel. For someone who plays games a lot , you are getting your ass kicked. Badly." Kayla said as she tried not to laugh.

"Oh hahaha. Very funny , Kayla." Miguel rolled his eyes as he sat on the couch , holding his head.

"Alright , just one more time , you-"

Just at that moment , screams were heard from outside as multiple Carddroids rampaged through the town.

"Oh."

"Shit."

"What do you mean the real threat are the Riders?" Sean questioned Ryūtaro as he stood up.

"Each Rider has their own desires. Some good and some bad. Kuroshima fights in order to cure his mother's cancer and Fushimi fights in order to get out of poverty." Ryūtaro says , taking a sip of his coffee. "So , Harada. Why do you fight? Why did you become a Rider?"

"I want protect my friends and family. Thats all."

"Thats it?" As Ryūtaro puts down his cup , he heard a beeping noise coming from his phone and looked at his phone. "A Carddroid is attacking downtown. Looks like you should hurry."

"Y-yeah." Sean gets up , heading to the door.

"Wait."

"Huh?"

A card was thrown at Sean as he catches it. On the card , it had a crimson ninja on it with the word 'SHADOW' on it. "Shadow..."

"Just a little upgrade for you. Go and save your friends."

Sean looked at the card , hesitant , but nods as he leaves.

'Now...show me your strength again...Harada.'

Already transformed , Robert and Miguel were facing the massive horde of Carddroids that were swarming at them.

"Fucking hell! Just how many of these bastard are there!?" Said Crusher as he drills through the Carddroids , one by one.

"These guys just keep coming!" Skylark slashes them into pieces and sees the man with the Katana from before. "Guess that's their leader."

Kage smirked as he unsheathes his Katana , pointing it at Skylark and Crusher. "Prepare yourself." said the Carddroid as he transform into his monster form and charges at them , swifttly striking at them.

The two Riders stumbled back , holding their chests in pain.

As Kage wasstrike at them once more , Sean appears on his bike as he rides towards Kage and hits him with the front wheel. "Stay the fuck away from my friends!"

"Harada..." Skylark gets up with Crusher as they see the horde of Carddroids swarming around them.

"Aw fucking hell...this is not good."

"We're surrounded..."

"Son of a bitch..." Sean cursed under his breathe as he sees Kage getting in his stance again. 'Wait a minute...the card that Sakaguchi-sensei gave me!' His eyes widen as he pulled at the Nexus Card Ryūtaro gave him and his Nexus Driver. "Okay , Shadow. Lets see what you can do." He puts the Nexus Driver on his waist and opens the slot and puts the Shadow Nexus Card in it.

[RIDER CARD!]

"Henshin!" He closes the slot down as crimson cards surround and turn into armor.

[LETS RIDE : GAIA SHADOW!]

A japanese flute plays as the cards turn into armor and attaches to Sean's body. The armor was black and red and had a ninja design to it. Gaia grabs Gaia Blade from his left side and gets in a low stance. "Game...start!"

(Wagakki Band-戦 Ikusa plays)

Gaia jumps in the air and throws multiple kunai and shuriken at the oncoming Carddroids , taking out a good few of them as he lands back on the ground and does a spinning side kick to another Carddroid , sending it flying.

Kage growls in rage , seeing many of his allies getting cut down by this...this damn human! He charges to Gaia as fast as he can and swings wildly , making it easy for Gaia to dodge.

"Got you!" Gaia grabs Kage by his arm and slices a X on his chest and kicks him back. Skylark jumped from Crusher's shoulder and plants Skylark Talon to the ground , creating a massive shockwave. "Miguel , now!"

"Gotcha!" Miguel summoned his weapon , Crusher Driller, a yellow and silver gauntlet with two drills on it , as it appears on his right arm. As he jumps in the air , he opens the slot of his Nexus Driver and presses on the R button on it.

[HISATSU! (CERTAIN KILL!) ]

The drills start to spin rapidly as yellow energy swirls around them , debris swirling around it. Crusher dives down , closing down the slot of his driver.

[FINAL RIDE : CRUSHER!]

Crusher dives to the Carddroids and throws a big hook , the energy from the drills of Crusher Driller cuts through the Carddroids , one by one as he lands on the ground.

"Another on bites the dust."

(Song ends)

Gaia punches Kage in his stomach and spins kick on his head , causing him to fall to the ground. Kage gets back up , staggering , still holding to his Katana. "You're still going? Damn , don't you Carddroids even know when to give up?"

"For my lord...I will s-"

'Kage. Get back here. Thats enough for today.' Jin said via radio.

"Tch. Time for me to go..." He sheathes his Katana and turns back into his human form. "Looks like a draw this time , Gaia. But next time , I'll have your head." He turns around and disappears in black smoke.

Gaia sighed as he pushed the slot of his driver , takes the Shadow Nexus Card of it and closes it , dehenshining.

"You know...its pretty cool being a ninja."

"Sean , are you alright!"

Sean turns around to see Kayla , Ana and Cameron running to him and sees Robert and Miguel walking to him , already dehenshined.

"Are you okay , Sean-kun? Did you get hurt?" Kayla asked , worried about her best friend and love.

"Yeah Kayla. I'm okay." He smiles as he pats Kayla's head.

Ana smiles at Sean and hugs him , resting her head on his chest. "I'm just glad you're okay , Sean."

Miguel and Robert smiled at the scene as Cameron chuckles.

"Well , Aniki , atleast you're now closer of getting a threesome."

Sean's eyes widen as Kayla and Ana blushed red. 'Mmmmm...Threesome with Sean and Ana...' Kayla thought seductively and licked her lips as Ana squeaked and hides her face with her hands.

"Cameron...Remind me to smack the hell out of you with a frying pan." Sean said still blushing. But , maybe a threesome would be great.

"Thats enough data..." Jin smirks as puts the finishing touches of his new driver. It was a red bulky driver that looked like a Nintendo 3DS that had a silver handles on both sides of it. "The Stylus Driver is complete. And the one that shall use it is..." He grins as he sees Ryūtaro entering the lab. "Sakaguchi-kun."

"Is it done?" Said Ryūtaro as he looks at the bulky driver in Jin's hands.

"Yes it is , my friend. And now , time to let some more players join this little game of mine." Jin walked over to a table that had multiple Nexus Drivers on it. "The real game begins..."

Meanwhile , at a unknown forest...

A man in black ancient loose armor

and short black hair walks around , looking confused of where he is.

"Where...am I?" his eyes flashes red as he looks at a blood red full moon.
