So Far on HyperDimension Decade

?: Defeat Decade but don't kill him

Ace: This Lastation

Uni: I'm Uni.

Underling: What the hell?!

Uni: Nepgear… you're a…

Nepgear: Could you please help us?

Uni: I never want to see the both of you again.

Eternal: Prepare to fell Hell itself

"Henshin- whoa!" Ace shouted as he narrowly avoided a strike from Eternal.

Kamen Ride: Decade

Decade pull out his ride booker and put it sword mode as he clashed with Eternal's dagger, the Eternal Edge. Eternal merely kicked Ace back before he blocks Nepgear's sword strike.

IF went on the offensive as she slashed Eternal but the white rider merely blinded her with his cape. Eternal then slashed IF before taking out a Gaia memory.

Unicorn

Eternal then placed the memory in a maximum drive slot near his arm.

Unicorn: Maximum Drive

"RAAAAAH" Eternal yelled as he delivered an energy drill punch at IF, who was just nicked by it but the force of the punch sent her flying near the each of the platform. Decade and Nepgear tried to slash him but found it hard to even hit him.

"Hold still you!" Decade shouted as he tried to slash Eternal. The white rider decided to counter attack Decade and Nepgear with multiple slashes.

"RAAAAAH" Eternal roared as he sent Ace and Gear flying backwards. Nepgear tried to get up but froze upon seeing Eternal, with flames surrounding him like he was the devil's incarnate, again as his image was replaced with the person who defeat her and the CPU's years ago.

"N-n-no stay away" Gear begged crawling backward.

"It ends now" Eternal said as he pulled out his Eternal memory and placed it in the Maximum Drive slot on his side.

Eternal: Maximum Drive

Eternal had his leg blaze with blue flames before he jumped for a rider kick.

"NEPGEAR NO" Decade yelled as he ran right in front of Eternal's Rider Kick and Nepgear crossing his arms.

"HAAAAH" Eternal roared as he hit his mark as the kick pushed Ace back as bit as he growled trying to stand his ground before he was sent flying.

"ACE" Nepgear screamed in horror.

"Now enjoy Hell." Eternal said turning away giving a thumbs down while an explosion occurred behind him.

"GAAAAAAH" Decade yelled as he was sent flying again from explosion of the finisher before ending up on his back, automatically powering down, beaten, battered, and bruised like hell.

"Ace!" Nepgear screamed as she ran toward Ace, who was barely conscious by the finisher.

"It's your turn next." Eternal said as he went forward when something hit him. Eternal looked behind him to see something.

"Auto… Vajin" Ace got out as he saw it ram Eternal into the ocean and transformed into a familiar bike, Decade's bike to be exact the Machine Decader. IF saw this and knew this was their chance to retreat, so she hopped on the bike as it drove toward Ace and Gear.

"Nepgear, we're getting out of here." IF said as Compa hopped on the bike too.

"R-right" Gear said as she picked up Ace onto her back and began to fly away.

"Iffy do you known how to ride this?" Compa asked.

"I have my own bike buts it's in repair shop right now. Let's hope this thing can ride well." IF said before revving up the Machine Decader, as she and Compa raced away from Eternal with Nepgear flying.

"Ace please hold on" Nepgear pleaded as Ace fell unconscious from all his wounds.

Eternal, who jumped out of the ocean, glared as he prepared to follow them but got blasted from behind he turned to see someone in the shadows with lens lit up, holding up a gun but couldn't what the thing looked like.

"Sorry I can have you follow him so you can play with me instead." The figure said as he brought out a small orange mini car.

Cue Journey through the Decade

(Instrumental) The destroyer of Worlds; Decade what will he see as he travels to save one. Card flew out of the picture of the last scene as they flew into Decade's mask, who stood in a white area with data codes in the backround and picture films.

(Miageru Hoshi) Ace is seen walking down an alley in Planeptune's main city holding the Decade card.

(Sorezonere no kishi ga kagayaite) Ace looks at the card before it flashes to the other Kamen riders from Kiva to Kuuga. Nepgear is seen looking at the sky from the Basillicom as she remembers her sister.

(Seiza no you) IF is seen by her bike with Compa as their other allies are seen flashing on screen.

(Sen ga musubu shunkan hajumaru legend) Uni, Ram, and Rom and the Oracles for each land are seen looking at the entrance of Planeptune's main city as darkened images of the Heisei riders are seen with only their eye pieces in color.

(Oorora yurameku jikuu koeta) All of the CPUs are seen held captive ASIC commanders appear in front of them at the graveyard.

(Tobikomu meisou suru Parallel World) Ace freezes up as he falls into nothingness while the suits of each rider appear on his right side before it ends with Decade. The scene switches to Ace preparing to transform with the other CPU candidates.

(On the road Daremo tabi no tochuu) Decade stands with the IF, Compa, and Nepgear (in HDD form) weapons out as they are surrounded by monsters as Decade charges forward with his Ride Booker in sword mode.

(Journey through the Decade) The two ride into a silver veil as it shatters with the 9 Hesei riders in battles pose behind them before they go in clockwise order with the four CPUs in the separate corners of the screen as the title appears

The Rider From Hell.

IF, Compa, and Nepgear had finally got away from Eternal and immediately brought Ace to a hospital. The doctors saw how bad Ace was immediately put him on a stretcher.

"Please wait here." The doctor said as they took Ace inside. Nepgear, meanwhile, was looking at the doors as tears began to well up.

"Ge-Ge" Compa said as she saw her CPU candidate friend in emotional pain first she lost Uni then Ace had taken a blow for her.

In the operation room the doctors were producing all the healing items they had and stopping the blood from bleeding out of his wounds while Ace's hand twitched bit.

(Meanwhile with Eternal…)

Daido growled as he limped away from an area, he was fighting Decade before suddenly someone interrupted his fight what was worse was that he only had his Eternal, Unicorn, and Zone memories but couldn't go into his final form for some reason, in short he had to flee from the other rider that appeared.

"I see you noticed" the white rider looked behind him to see someone in a black coat. "You feel that your power is weaker than before well that is because of me, I can have you disobeying me Eternal." The man obviously pissed off the NEVER subject who brought out his Lost Driver ready to kick his ass but the man suddenly vanished before appearing before his face and sent him flying backwards with a single punch. "You will listen to me Eternal, and you will obey or I will make your life a true hell." The man brought out the Eternal memory.

"Now then, do we have a deal?" The man grinned wickedly at Eternal who growled and nodded "Good now then I want you to draw out Decade and don't worry about holding back just make sure I see him." 'And soon his powers will be mine.'

Ace groaned as he felt like he had a bus dropped, he stood up as he looked around only to see fog all around him "What happened?" the last thing he remembered was fighting Eternal and then…

"Gear" Ace looked around all panicky "Where Nepgear?" Suddenly Ace remember what happened, he took the hit for Nepgear. "That's right I took the hit for Gear, but Eternal he's still out there." Ace looked down how could he be Decade, he was supposed to be the strongest rider out of all the Heisei Riders but still he was newbie compare to Eternal and the other riders.

"What chance do I have?" Ace looked himself he was no Tsukasa, nor Gaim, W or even Drive. Suddenly Ace heard footsteps as he looked to see 7 silhouettes staring at him. "Who are you?" Ace asked when six of them took out some items and threw them to Ace as he caught them. "What the…"

Ace was now holding 6 items in his hand.

A black USB with a J on it in purple flames: the Joker Gaia Memory from Kamen Rider W.

A red medal with the image of a hawk on it: the Taka (Hawk) Core Medal from Kamen Rider OOO.

A switch with a button up top and a number 1 on it with the image of a rocket: the Rocket Switch from Kamen Rider Fourze.

A ring with a red ruby also having a little piece that looked like goggles for it: the Flame Style Ring from Kamen Rider Wizard.

A pad lock with an orange image on it with the code LS-07 on it with the black lock on it: the Orange Lockseed from Kamen Rider Gaim.

The last one was a red toy mini car with white lines and yellow lights on the front: the Speed Shift Car from Kamen Rider Drive.

"These are the…" Ace realized they were transformation Items for the Neo Heisei Riders, but as soon he knew that the people began to leave, "Hey wait, what do I do with these?"

"Use them to carve your future." Someone said as the silhouettes disappeared.

"No wait" Ace yelled as the area became pure white.

Ace sharply opened his eyes as he groaned sitting back up, he saw that he was in a hospital he groaned as he got up weakly from the wound he received against Eternal and felt his hand gripping something and saw 6 cards in his hand, the cards were sealed like the other ones but he could make out the riders.

"W, OOO, Fourze, Wizard, Gaim, and Drive cards." Ace said seeing the head outlines, he didn't think that he could use the Neo Heisei riders' abilities he was also surprised with Drive being in his card collection considering he was taken from Earth when Drive had just achieved type Tridoron in episode 33.

"Ace." He heard Nepgear say as he looked to see her, IF, and Compa at the entrance of the room.

"Gear girls." Ace groaned as he propped himself up.

"ACE" Nepgear yelled as she ran and brought him into a hug.

"OW OW OW OW OW OW. NEPGEAR PLEASE MY WOUNDS!" Ace yelled in pain.

"Sorry." Nepgear said easing up on the hug but didn't let go. "But you had us worried for goodness sake."

"I'm sorry girls I just move when I saw… ETERNAL! Where is he what happened?!" Ace realized in panic that he was still out.

"I don't know he didn't follow us when we fled?" Compa said as Ace began to force himself out of bed after Nepgear had let go. "What are you doing Ace?"

"What does it look like I going to search for Eternal." Ace but winced after felling pain in his arm.

"Not with those wounds. You need to rest." IF pointed out. "Doctors orderssaid that you can walk but you need to take it easy to fully heal."

"But Eternal could…" Ace could finish as Compa gave off a dark aura.

"Doctor's orders if you want Nurse Compa to try and experiment on ways to make you heal faster I'll be glad too." Compa said sweetly as the other shook in fear of the aura she was giving off. Ace also didn't want that huge needle in who knows where since IF told him Compa was a bit of a clutz.

"Ok I'll stay, I'll stay, just keep the needle away!" Ace yelped as he got back in his original position.

"Ace why did you want to go after him, he's dangerous I think we should avoid him for now." Nepgear said. She was still traumatized by what happened 3 years ago and Eternal just somehow brought it all back.

"I can't I'm the only one who can stop him." Ace said. He had the power of one of the most powerful Kamen Rider in the Heisei line up next to the Neo Heisei ones like Gaim and the rider lockseeds so Decade was the more likely one to defeat him and the fact that Eternal was powerful even without all his T2 Gaia Memory, just a couple could make him even more dangerous and deadly.

"Ace you can't just go after him when you just got wounded in battle, besides I bet Eternal is just as tired." IF said but got stares from Compa and Nepgear. "What"

"Iffy I think you may have said something to invoke Murphy's Law." Compa said.

"Really Murphy's Law I don't believe in that…"

KAAAAAAAAAAAAAAAAAAABBBBBOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM

Suddenly a giant explosion occurred near them shaking the building they were in, IF gave a look at the trio. "Don't you say a word," she simply said

"Look outside!" Nepgear said as they saw out the window was Eternal attacking from the roof of a building.

"Eternal seriously" IF growled why did Murphy have to come at them full force.

"What do we do Iffy?" Compa asked.

"Only thing we can do, stop him from destroying the city."

"AHHHHHHH" Nepgear screamed as the two turned to see Nepgear looking at Ace's bed which was now empty.

"Ace is gone!" Compa yelled in shock.

"Idiot! He must be going after Eternal then." IF growled, Ace was obviously the type to think about others before himself in a situation like this.

"We have to hurry before he get himself hurt or worse." Nepgear said not wanting to think of what would happen if Eternal wasn't merciful on Ace's life.

Ace ran, ignoring his wounds, as he saw people run with Eternal blowing things up one by one, he knew why Eternal was attacking, to draw him out. As he ran to where Eternal most likely was IF, Compa, and Nepgear all running after Ace to stop him from doing something stupid.

"Come out Decade or everyone here will see hell!" Eternal said.

'I have to do this no one else should get hurt because of me.' Ace as he took out his driver attaching it to his waist while taking out his card when Nepgear suddenly grabbed his wrist.

"Please Ace don't do this." Nepgear begged. "Please let us handle it while you rest."

"Nepgear I have to do this. I can't let anyone die, because I'm a Kamen Rider now." Ace said with determination as he removed Gear's hand from his. "Now stand back all of you."

"HENSHIN" he shouted.

Kamen Ride: Decade

In a flash Decade had appeared again running right at Eternal sword drawn and ready as Eternal, hearing the transformation, ran right at his target. The two clashed sword and dagger multiple times before Eternal pulled out another two memories.

Heat

Cyclone

The two memories that Philip would use for his side of W was equipped on Eternal's maximum drive slots near his arm. Eternal then punched Decade with an added effect of a fire and wind forcing him back.

Decade brought out his Ride Booker in sword mode before charging as Nepgear kept watching with awe and concern. Ace refused to back down even with his wounds, he felt it was his duty to protect people. She was a CPU candidate it was her job to look after her nation yet she was scared of this rider yet Ace wasn't and he was fighting him.

She watched as Ace clashed with the dark Kamen Rider as they battled sword for dagger. Ace tried to deliver a head butt but Eternal jumped back as the magenta rider tried to rush him but his wounds prevented that as he winced in pain Eternal pulled out another memory.

Accel

Eternal began to move faster with the new Accel memory as he delivered multiple punches at Ace. Ace pulled out a more recent card in response to the Accel memory boost.

"Better end this fast." Ace said inserting the card.

Form Rider: Faiz Axel

In a flash of photon lining Ace became Faiz Axel form his fastest one for now. This one had a stop watch on his wrist as Ace start button on it.

Start Up

Immediately Ace ran faster than Nepgear's eyes could register almost at the same speed as Eternal was moving making them look like blurs. Meanwhile in Ace's eyes he felt like he was moving at the same speed as Eternal now.

D-Faiz tried to strike Eternal with a sidekick but got caught by the white rider as Eternal attacked Ace's leg but the magenta rider used his other leg to get free from Eternal. With Nepgear she saw only blurs as if they were clashing for only a second before flying past each other at blinding speed.

"Waaaaaah" D-Faiz and Gear both saw a little girl crying all alone. Eternal got his weapon out again and put in the HEAT memory.

Heat: Maximum Drive

"RAAAAH" Eternal yelled as he delivered a flaming energy slash right at D-Faiz.

"Crap" Ace swore, if he moved the girl would get fried and killed, immediately D-Faiz ran back and covered the girl as the attack stuck him in the back.

"GAH" he yelled as the flamed stuck him hard.

Time Out.

Soon D-Faiz was Decade again but the girl looked at him seeing the warrior protect her in shock and awe.

"You ok?" Ace smiled under his mask as the girl nodded. "Go find your mommy, K." the girl nodded as she ran off as he saw the girl's mom who took her away from the fighting., Decade winced in pain of the attack.

Nepgear looking on as Decade stood up and charged at Eternal again, Ace was fighting as if it was his last and was protecting people instead just trying to only beat Eternal.

"I can't let anyone die."

"A Kamen Rider fights for Humanity's Freedom."

"I refuse to let someone be hurt because I couldn't do anything!" Ace was working to make sure no one was hurt and trying to live up to the title he had now been given. Gear knew now she couldn't just let fear rule her now, she immediately ran forward

Decade skidded back as Eternal walked towards him calmly before Nepgear suddenly appeared in front of him and tried to slash to him but the white rider jumped back.

"Gear what are you doing?" Decade said in shock

"Ace I'm fighting too now." Nepgear declared.

"I won't let you take on the burden alone now Ace I'm a CPU and I have duty to stop ASIC and these Dark Riders," Nepgear said holding out her sword. "I refuse to let you have this burden alone and I don't want to lose my friend either."

"Gear" Decade looked as Gear had regained her courage again.

"So please let me help." Gear said.

"Your right I'm an idiot I forgot I'm not in this alone I have you, IF, and Compa by my side." Decade said as he stood up. "So this time let's fight him together and show him what our power can do."

"Right" Gear smiled before a light shined from her body. "What the goodness." Suddenly the light came out of her body to form two cards for Decade.

"These are…" Decade looked at the cards the floated into his hand one with a yellow N symbol another card holding Nepgear's image of her human and CPU form while on the upper part of the having Nepgear's Gunblade on it and the card reading "Nepgear Gunblade". Ace immediately took the latter of the two and put it in his driver.

Final Form Ride: N-N-Nepgear

(Cue Ride the Wind by Masahiro Inoue (Tsukasa Kadoya))

"Nepgear this gonna tickle a bit." Decade said getting behind the CPU candidate.

"Ehh" Nepgear questioned before Decade SHOVED HIS HANDS INTO NEPGEAR'S BACK! "WHAT THE GOODNESS?!" she exclaimed.

"GE-GE?!" Compa exclaimed as they watched.

"WHAT THE HELL?!" IF exclaimed in shock.

Decade spread his arms out as if opening Gear's back as white machinery appeared on her back as Nepgear suddenly jumped into the air before suddenly changing into a larger version of her HDD gunblade. (Think of the Neptune's Nepgear HDD from Neptunia V)

"Ace what is this?!" Gear exclaimed in shock from her Gunblade form.

"This is… our new power." Decade said grabbing hold of the blade as he got used to the weight of it before charging at Eternal swinging the blade causing major damage. Eternal tried to use the Accel memory speed to get away but Decade fired energy shots from the blade causing him to be sent back. Decade rushed forward as he swung the blade at Eternal forcing him flying backwards.

"Try this now!" Decade shouted as fired lasers at Eternal who yelled in pain. "Ready to end this Gear?"

"Yeah" the gunblade said.

"All right then, Eternal!" Decade yelled as the weaken Eternal looked to see Decade holding a card with a large N on it with the words Gear written on the N. "Let this be a lesson, the dead have no place among the living."

Final Attack Ride: N-N-Nepgear

Energy gathered at the tip of the blade it glowed bright magenta while one card was in front of Decade a few feet away.

"Decade Severance" Nepgear and Decade shouted in unison as the gunblade finished charging and fired an energy blast that went through the final attack card causing it to split apart and converge onto Eternal from multiple sides.

"GAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH" Eternal screamed as the lasers pierced his body while his body spark with electricity and…

KAAAAAAAAAABOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM

Decade saw the explosion occurred where Eternal was standing as the Eternal Gaia memory flew out of the explosion before shattering into pieces before even falling to the ground. The Lost driver looked beyond repairs as well. Decade threw Gear into the air as she unfolded in midair.

End Song

"Whoa whoa whoa WHOA" Nepgear stammered as she fought to gain back her balance as Decade powered down as Gear fell on her butt. "A little more warning next time Ace!" Gear snapped.

"Sorry, did warn you it would tickle." Ace shrugged as Nepgear suddenly hugged him. "Gear"

"You're not alone Ace I swear I won't let you fight alone." She said honestly as Ace hugged back touched by her words. The two stood for a while just taking in the peace before...

"Excuse me, lovebirds are you done now." IF said as Ace and Gear opened their eyes wide to see IF and Compa looking at them making them separate and look away from each other blushing.

"We may want to get out of here before people start asking questions." Ace said seeing the damage from the fight before wincing as he began to feel his legs lose their ability to stand before he fell.

"ACE" Nepgear yelped as she grabbed him before he can hit the pavment.

"Sorry I think I used up all the energy I had left in that fight."

"(Sigh) Looks like it's back to bed with you." IF sighed. "Gear carry him back will you."

"R-right" Gear said.

"Don't worry Ace I'll be sure to take good care of you Nurse's honor." Compa said.

'It's what you are going to do that makes me worried especially with that needle.' Ace thought in a panic.

"Ace thank you I mean it." Gear said as they walked away.

"I know Gear and thank you." Ace said as he looked at the Nepgear cards he had now along with the Neo Heisei ones. "My own future huh."

Unknown to the group a red two doored car with black sides, padding, a square top, white lines that went to the headlights, two extra wheels on its wings, and a police emblem on it drove up to the place where Eternal and Decade fought as the driver car door opened up to reveal a Kamen Rider with red armor that resembled a race car, a black bodysuit, red gauntlets and boots along with silver knee pads, silver wristbands, two white lines on the helmet, the eye pieces resembled car headlight and he had a silver mouth piece. His body had a tire with a red line across it saying Type Speed on his left wrist was the shift brace and Shift Speed and across his waist was the Drive Driver.

"He did Belt-san." The man said.

"Yes but Eternal is just the beginning of what is to come now." The belt said with a glowing red lights that formed a face.

"Right looks like it's time to get into Top Gear." He said.

Yes Kamen Rider Drive knew what he had to do.

The Image of Drive freezes as the Decadriver appears around it before closing with the Neo Hesisei rider Symbols on it the driver as Drive's symbol glowed.

Next time on Hyperdimension Decade:

Ace: I can't believe that Oracle would be more concerned about business then her own goddess and the Mascot!

?: I see you need help the name is Tanikaze Hiro.

?2: Start your Engine!

Nepgear: No way?!

IF: He's a…

The whole team: Kamen Rider?!

Hiro: You're under arrest!

Who is this new Rider?

Kamen Rider?: Let's go for a ride.

Destroy Everything to Connect All

Omake 3: All in the cards

Decade, Ryuki, Blade, and Gaim all sat at a poker table as they played Texas Hold'm with Decade and Ryuki on one team and Blade and Gaim on another.

"Three of a Kind." Gaim said showing his hand.

"Straight Flush" Blade smirked showing his hand as Decade and Ryuki looked at each other nervously before Decade gave a nod the Dragon Knight who took out a card and put it in his Drag Visor.

TIME VENT

Decade, Ryuki, Blade, and Gaim all sat at a poker table as they played Texas Hold'm with Decade and Ryuki on one team and Blade and Gaim on another. Wait a minute.

"Does anyone feel like we gone through this already." Blade asked.

"Nope" Decade and Ryuki said as the saw their hand now that Decade used Faiz Axel to get them a better hand.

"Whatever we got this." Blade said.

Two minutes later.

"ARE YOU FREAKING KINDING ME" Blade yelled in shock he and Gaim lost all their money to Ryuki and Decade who had a full house in their hand.

"How did you do it." Gaim asked depressed.

Just got to have a trump card at least." Ryuki smirked as Decade snickered a bit.
