" Cheers to a fantastic performance ."

In the famous restaurant, Nabezo Shibuya Koen Dori in Tokyo Cho and Senji were sitting in a booth holding their respective drinking glass toasting in the success of the performance tonight. Senji see Cho is smiling at him making him feel weak and he is wondering how he was able to get a wonderful girl like Cho as finance.

Cho said," You are so amazing on the violin Senji." She smiled at Senji giving him a beaming smile.

Senji said," Thanks Ch-Cho."He stumbled a bit but he composed himself and he see Cho looking amused.

Cho grasps Senji's left hand and she rubs it then making Senji blush making Cho giggle but before Cho could do anything else the sound of the glass breaking gaining the patron's attention cased to see a monster is in the restaurant.

The monster with a crocodilian head with a crest. Its glaring face has two swivel-socketed green eyes, a snouted nose, no ears, and a tiny large-toothed mouth. Attached to its short, muscled bear-like torso are two insectoid arms ending in tentacle-fingered and hooved legs. Its whole body is covered with grayish warty skin. It has fan-like wings.

The creatures roared," Must have Cho Chang." The creatures let out a loud roar that caused the patrons to run away.

Senji said," You know this creature, Cho?" He looked at Cho who shook her head signaling no making Senji suspicious.

The Creature said," Must have Cho Chang! Must have Cho Chang!" The Creature was stopped by a blur causing it to be sent flying into a wall.

Cho and Senji see it was long, messy black hair tied with a bandage around the tips. She dresses in dark colors and tattered clothing, and her left arm is perpetually bandaged. Cho and Senji's jaw dropped when she saw the woman.

Senji thought " Who is this woman? Is she a Fangire?" He looked at Velvet Crowe in astonishment.

" Geez remind me not to make you mad Vel."

Senji and Cho turn to see in the doorway where Alfred holding his briefcase and he walks towards the scene making the couple wonder who is this mysterious duo. Alfred opens the briefcase revealing the shadow driver and he places it on his waist along with taking out his transformation card he presses the button on the left then insert the Transformation card causing the screen of the driver to show the Rider form

Alfred cried," Henshin!"He presses the right button causing the Driver to activate making Cho and especially Senji stunned.

"Chosen by Darkness! Blessed by Magic, Fate, Destiny, and Death! Lord of Serpents! Kamen Rider Shadow! (All hail Shadow! All hail Shadow! All hail Shadow!)"

The couple watches Alfred is covered in shadows casing him to form around him like it was the armor of some kind then as takes the form of his Kamen Rider Form. The helmet is a Mega man X helmet but colored black; Unicorn Gundam Unicorn Mode faceplate and vision but change the white to red and the green to gold; Add in the Strike Gundam's V-fin (It is attached to the red gem).

The bodysuit is Kamen Rider Chaser's bodysuit with the white change to black and purple is a change to silver with the Digimon Hazard symbol colored gold; The Bakugan Gauntlet minus the cardholder thing and it holds his deck of cards like the thing Yusei wears during a Turbo duel and It's primely color is silver while its secondary color is gold.

Cho said," By Merlin ?" She looked at the armored figure in the place of the American boy and she see Senji is stunned.

Senji whispered,'" A Kamen Rider ?" He looked at the new Kamen Rider in front of him and he wonders about this new rider.

Kamen Rider said," Embrace the shadows Kamen Rider Shadow!" He does a brief pose and he draws a card and he summoned his weapon. Kamen Rider inserted the card into the driver causing the attack to activate.

" Shadow Card! Slash!"

Cho and Senji watch as the sword part of the blade glow purple then the Kamen Rider charges towards the monster and slashes the beast making it scream in pain then Kamen Rider Shadow does a tornado kick that sends the beast flying out of the restaurant.

Kamen Rider Shadow said," Time to hunt down a monster!" He draws another card from his gauntlet and inserted it into his driver.

" Shadow Card! Summon Shadow machiner!"

Kamen Ruder flips in the air and he landed on his bike then he rides off to track down the creature leaving Velvet, Cho, and Senji alone in the restaurant. Senji wanted to know what was going on and he wanted answers now.

Senji said," Cho I am going after them ."He grabbed his instrument briefcase and he jogs after the new Kamen Rider.

Cho said," Be safe!" Cho looked at her lover with a smile on her face that reached her eyes making Velvet raise an eyebrow.

Velvet thought " There is something off about those two.'' She looked at Senji and Cho as she felt something strange about them.

Meanwhile, Kamen Rider Shadow is battling against a Shadow Beast with a crocodilian head with a crest. Its glaring face has two swivel-socketed green eyes, a snouted nose, no ears, and a tiny large-toothed mouth. Attached to its short, muscled bear-like torso are two insectoid arms ending in tentacle-fingered and hooved legs. Its whole body is covered with grayish warty skin. It has fan-like wings.

Kamen Rider Shadow punches the Shadow Beast in the face then he Shadow delivers a punch to the midsection of the Shadow Beast making the beast roar in pain. Kamen Rider landed a two punch combo that rattled the shadow beast.

Kamen Rider Shadow said," Time to finish this !" He draws a card from his shadow gauntlet and he was about to insert it into the driver.

" Ah crap !"

Kamen Rider Shadow paused as a brown instrument case landed near and he see a is a slim built young man of Japanese descent with ink-black hair that he wears a white headband under his hair and he has gold eyes wearing a black sweater with a black scarf around his neck and grey pants. He also have on a black trench coat.

Kamen Rider Shadow said," Here you go pal and you might want to get out of here ." He picked up the briefcase and he handed the instrument case to the young man.

The young man said,'' Thanks but I can take care of myself and I will leave when I defeat that monster ." He accepted the briefcase from Kamen Rider Shadows with a smile.

Kamen Rider Shadow thought "Defeat this shadow beast?" He looked confused as to how this average joe will defeat this shadow beast.

The youth cried," Kivat!" He got Kamen Rider Shadow's attention when he cried out Kivat because Kivat isn't real.

" KIVAT IZUKE!"

Kamen Rider Shadow eyes nearly threaten to pop out as he see a red and black mechanical looking bat flying towards the unknown young man before. Kamen Rider Shadow watches as the boy grabbed the bat and he brings him down to his hand.

GABU!

Kamen Rider Shadow sees glass markings that appeared on the boy's skin and he see blood-red chains wrapped around his waist and made a red belt with different whistles on the side. Kamen Rider Shadow couldn't believe this.

The young man cried," Henshin!" He thrust Kivat in the air. He placed Kivat on the perch upside down. Kivat gave off multiple sound waves as the boy's body was covered in quicksilver. His body then morphed before the quicksilver broke apart. When it did, an armored figure took the boy's place.

The armored figure has a full black bodysuit that consisted of red bracelets on his wrists which stretched over his forearms, black shoulders had spikes on them that jutted upwards. On his chest was a stained blood-red glass flower pattern. His lower torso with blood-red armor similar to Dark Kiva's lower torso. Finally, his head was covered with a black helmet with the visor with a red eyepiece which gave the resemblance to fangs, a black faceplate which was resembled bat-wings, and a smaller black bat-wings head crest with a small circular yellow gem. His mouth plate was silver framed with black fangs.

The new rider introduced," Wake up and break the chains of destiny Kamen Rider Neo Kiva !" He does a brief pose similar to Kamen Rider Kiva and he charges at the Shadowbeast with Kamen Rider Shadow watching.

Kamen Rider Neo Kiva lands a barrage of punches to the Shadow Beast then a sidekick that sends the beast flying to a metal pole. The Shadow Beast roared then it gets to its feet and the beast takes flight.

Kamen Rider Neo Kiva said," Not on my watch!" He grabs a green Fuestles with a fish's head. He placed it between Kivat's mouth and blew into it. The Fuestle then made the sound of a trumpet.

"BASSHAA MAGNUM!"

A green streak flew through the air as Neo Kiva dove into the water. The streak followed him and the pool water was bathed in a green glow. Kamen Rider Shaod watches in stun silence as he see a green meteor coming right at them. The green light hit Neo Kiva and he was now clad in scaly green armor that covered his chest and the entirety of his right arm with his forearm and shoulder had fins on them and his yellow eyes were now green. In his right hand was a strange green gun. This was Neo Kiva Basshaa Form.

Kamen Rider Shadow said," Holy shit!" He see Neo Kiva form and he always wonders what it likes to see a fellow Kamen Rider secondary form.

Neo Kiva red water projectiles at the Shadow Beast and Kamen Rider Shadow watch as some of the bullets hit the shadow beast but some missed because the creature dodges the bullets.

"Shadow Card! Attack: Rider Shot!"

Kamen Rider Shadow fired a blast at the creatures' wings causing the Shadow Beast to come crashing down to the ground making the two-rider regroup as they see Shadowbeast is weakened in front of them.

Kamen Rider Neo Kiva said," Hey Shadow let finish it!" He looked over at one another before nodding as Neo Kiva grabbed a clear whistle with a red top. He inserted it into the bat's mouth which the following blew into and Alfred inserted a card into his driver.

" Wake UP !"

" Shadow Card! Attack: Rider Kick!"

Neo Kiva crouch down, with his arms covering the front of the helmet. When he spread out his arms, Kiva stood up on his left leg while kicking up his right one high into the air. The bat broke off from his perch on the belt and flew around the chained appendage. As he did, the chains flew off and the metal opened revealing a blood red inside. The pieces of metal were still attached to the foot, and they looked like red bat wings. In the center of the boot were three large green gems.

Neo Kiva Jumping high into the air, Neo Kiva seemed to float in front of the red moon, and Shadow jumps towards the Shadowbeast with Neo Kiva who a flying front kick towards the shadow beast.

"Darkest Moon Break!"

The duo rider kicks landed on the monster killing the beast as well making it explode into million pieces then the two riders landed on their feet looking at the spot where the shadow beast was at then the two looked at each other.

Kamen Rider Shadow said," Okay that was awesome!"He was amazed by the double rider kick he performs with Neo kiva.

Kamen Rider Neo Kiva said," Indeed but now I am more curious about who are you." He looked at Kamen Rider Shadow.

Kamen Rider Shadow said," It a long story friend." He looked at Neo Kiva and Alfred takes off his driver reverting back to normal.

Kamen Rider Neo Kiva said," Take your time."Kamen Rider Neo Kiva takes off Kivat his belt casuing him to revert back to normal.
