I don't own Mahouka Koukou no Rettousei or Kamen Rider and they belong to their respected owners.
"They're just using you, Mibu-senpai," Tatsuya says.
"Shut up! I'm doing this for Weeds like us!" Sayaka cried out.
"Don't be pitful Mibu-senpai. Don't you have people that acknowledge?" Miyuki says.
"You just don't understand!" Sayaka as she pulls out a Dopant Gaia Memory. She then reveals her Connector on the bottom of his neck.
T-REX!
"Mibu-senpai don't!" Tatsuya tried to reach out to her but it was too late.
Sayaka inserted the Memory and soon transformed into the T-Rex Dopant, making a loud roar. She was about to be charged at the Shiba siblings but was knockdown by a young man in a green and black motorcycle.
"Sam-kun!" Miyuki smiled.
"What is it now?" Tatsuya raised a brow.
"I've been trying to find the answer from our last conversation," Sam says stroking his chin. "But why did you hit me?" raised his hand out to Tatsuya.
"Hmph," Tatsuya smirked as he grabs hold Sam's hand with his saying they forgive each other. "Lend me half of your power, Aibou."
Sam smiled as he gave back Tatsuya his Double Driver and his three Gaia Memory. Tatsuya grabs them as they went out to face Sayaka.
"Ready partner?" Tatsuya asked as he pulled out a strange device from behind him. It was red and looked like it could hold something. He placed the Driver on his front waist as a belt manifest from the device connected it to the man. The Double Driver appeared onto Sam's waist.
"Just who are you two?!" Sayaka growled.
"The two of us are single detective," Sam answered.
"Let's go, Sam," Tatsuya says.
Tatsuya narrowed his eyes as he pulled out his Joker Gaia Memory from his pocket as Sam brought out a Cyclone Gaia Memory. The two pressed the buttons on the Gaia Memories activating it.
CYCLONE!
JOKER!
"Henshin!" They both shouted as they posed before the monster side by side making a W with their body and arms. Sam placed his Gaia Memory in one of the open slots where it quickly vanished and reappeared on Tatsuya's Driver. Sam then fell to the ground in a faint as Tatsuya then paced his own Gaia Memory in the other slot. He pushed the two slots to the side as they formed a W on the belt and it spoke once more.
CYCLONE, JOKER!
The wind picked up tremendously as a small green cyclone started to spin around the man along with purple tribal marks started to spread over his face. The wind faded and in the place around Tatsuya and was replaced by an armored warrior. His armor was split in half. The color on his right side of his body was green and his left side was black with the purple tribal markings on the body and arms. A small silver cape fluttered in the wind on the green side of the armor and its red compound eyes shined bright. On the top of its head were two V's that combined to form a W. This is the two-in-one detective, Kamen Rider W.
"Saa, omae no tsumi o kazoero!" said both Tatsuya and Sam as they did their signature pose.
"Miyuki-san, can you take care of my body please," Sam said as the green side, eye glowed as he talked.
"Don't worry Sam-kun," Miyuki replied as she grabs hold of Sam's body and began dragging it away to a safe distance.
W charged at the Dopant and began fighting her with kicks and punches but it was hardly doing anything.
"Stop this Mibu-senpai! That Gaia Memory is corrupting you!" Tatsuya said as he dodged any of her incoming attacks.
"Shut up!" Sayaka roared as she began to sucked in the debris they had. Soon the debris began to form Sayaka a giant robotic T-rex body.
Debris flew to W but they destroyed it as they kicked it. After destroying the debris Sayaka chomped onto W's right side and threw him into a wall making Tatsuya grunted in pain.
"Let's change my side," Sam says as he pulled out Heat Memory.
HEAT!
"Alright," Tatsuya agreed as he closed his Driver and pulled out the Cyclone Memory. He placed the Heat Memory into the empty slot and pushed open the Driver forming a W once again.
HEAT, JOKER!
His right side is now red with golden orange highlights. Sayaka began charging at W while the Rider clench his fist. As the Dopant came closer, W gave her a fiery punch making her recoil back. W then began to proceed to give her fiery punches until he sends her rolling onto the ground.
"It seems we should finish this Sam," Tatsuya said.
"Yes, we have to use the Memory Break," Sam says.
"I know!" Tatsuya says as he replaced the Joker Memory with the Metal Gaia Memory.
HEAT, METAL!
W's left side changed to a grey with silver highlights as a quarterstaff appeared on his back. W takes out the Metal Staff and extends it.
Sayaka threw debris but W blocks the concrete debris with his staff. He then placed the Metal Memory into the staff's slot.
METAL MAXIMUM DRIVE!
W charged towards the T-Rex Dopant as they dodged the debris being thrown at his way. The top end of the staff ignites on fire.
"Metal Branding!" W cried out!
W then bash Sayaka with the flaming end of the staff hitting her and sending her back as she exploded in flames. Sayaka's body fell from where the T-Rex head was but W caught her in his arms.
"It seems you were going to help Mibu-san," Sam said. "Even calling your teacher's favor pathetic."
"I remembered I gave Boss my word that I will protect this city and her people," Tatsuya says as he carries the unconscious Sayaka outside the school.
AN: I did Irregular Joker so I thought I should do my Irregular Double. I have a question of what you guys prefer W or Double because they use both versions of the names or should I just use both. Either way, this is the one-shot and you guys may be wondering why this anime, why Tatsuya, and why replace Phillip's name with same and that's because it was never done before, he is the protagonist so why not, and Phillip is always used in W x anime crossovers so I thought why not use another name. I'll congratulate you if you guess where I got the name Sam from.
