As the H/C haired teen ran forward, his thoughts of his friends came to mind, he was frustrated that he left his team back with Aku, but it was too late to turn back now as he gritted his teeth as he push forward.

Y/N: If they die on me, I swear I will kill them TWICE!!

Back with the Kamen Riders

The three teens kept their guard up, walking in different directions as they grew cautious of Aku.

Jack: Let's finish this quickly, we don't have enough time for this.

Aku: Aww, are you afraid of me being the best at making your lives hell?

Senkai: No, we just think that you're not worth the time.

Aku: Oh, you wound me.

He said as he laughed as Aku looked at them for a while.

Aku: Ryuga.

The same driver showed up on his waist as it blazes its black flames as Kado notices it.

Kado: Let's go guys. We need to catch up to them if we want to save Eri! Leangle!

A purple and gold belt appeared on Kado's waist as he was holding a card on his hand, putting it in the driver.

Senkai: Let's get this over with, I really hate messy fights like this! Snipe!

He said as the Game Driver appeared on his waist, pointing the Gaschat at Aku as he presses the button.

Gaschat: Bang Bang Shooting!

A game screen appears as barrels starts to fly out of the game screen, landing perfectly around the area.

Senkai: Tactics No. 2

Jack: This time, you're going down! Geiz!

He said as the Ziku Driver appeared on his waist, pressing the ridewatch as he twists it.

Ridewatch: Geiz!

Aku grinned as he made some hand gestures as well as the other 3 teens in front of him.

Aku/Jack/Senkai/Kado: Henshin!

Rouse Driver/Game Driver/Ziku Driver: Open Up!/Gachan! Level Up! Ba-Ba-Bang! Bang-Ba-Bang! (Yow!) Bang Bang Shooting!/Rider Time! (Electronic beat) Kamen Rider Geiz!

As the 4 riders transformed, they didn't hesitate as they started to charge at each other, throwing punch after punch at Ryuga as he dodges it perfectly.

Leangle: We need a plan, Senkai you'll be our eyes, predict his every move.

Snipe: Got it!

He said as he raises his Gashacon Magnum, shooting Ryuga down as Leangle and Geiz charges.

Ryuga: Still useless as ever.

He said as he draws out a card from the Advent Deck, placing it in his Blackdragvisor.

Blackdragvisor: Adobento!

Dragblacker appeared as he circles around the 3 Kamen Riders, waiting for Ryuga's orders.

Geiz: This isn't good.

Ryuga: Kill.

He ordered as Dragblacker started to attack, as Snipe gets to work. He started to fire down the dragon as it gains his attention, making a swift move at Snipe.

Snipe: I got its attention, so much for being the eyes. You 2 got this I'll distract his pet.

Leangle: Looks like we have no choice, let's charge head on Geiz!

He said as he takes out his Leangle Rouzer as Geiz takes out his Zikan Zax for a 2-on-1 assault. Ryuga noticed this as he draws out another card from the Advent Deck as he puts it in the Blackdragvisor.

Blackdragvisor: Sutoraiku Bento!

A dark version of Ryuki's Drag Claw appeared on his hand as he approaches the 2 riders, swinging their weapons at once as Ryuga blocked them.

Ryuga: Is that all you've got?

He asked as he kicks away Geiz as he punches Leangle away, making sure that he has the upper hand as Dragblacker as raining fire at Snipe, keeping him at bay.

Ryuga: The way I see things, this would be a glorious evolution that awaits us in the next era. Sadly for you lot, you're not here to even witness it.

Geiz: If that means people will lose their quirks because of a damned bullet, like hell it isn't an evolution to begin with!

He said as he charges right back, swinging his axe as Ryuga dodges it cleanly, punching him hard in his stomach as the wind left out of his system, stopping him from his attack.

Ryuga: How can you comprehend such things, it isn't my fault that Overhaul see things that way.

He said as he laughed, kicking Geiz away as Leangle charges back, swinging his polearm as Ryuga kept on dodging, picking his spots as he throws a punch at Leangle, kneeing him for a good measure as he kicks him to where Geiz was.

Ryuga: You should be at least grateful that I am keeping you alive just to see his plans turn into fruition.

He said as he uses the Drag Claw, extending his right arm as dark flames started to shoot out of it as it made its way towards the 2 teens, feeling the effects as they fall down.

Ryuga: Another boring fight, another bodies down. Let's end this shall we?

He draws his final card on the Advent Deck as he places it n the Blackdragvisor, the shades of their last meetup comes to view.

Blackdragvisor: Fainaru Bento!

Dragblacker started to drag Snipe towards Geiz and Leangle as it coils around them while Ryuga started to float up, extending his right leg as he started to float towards Dragblacker, dark flames started to engulf his foot as he delivers a rider kick, making a direct hit as he floats down.

Ryuga: Face it, even if you 3 combined forces, you wouldn't even have enough power to defeat me.

He stated as the fallen riders slowly scrambled to get up, grunting heavily as they feel the previous attack of Ryuga as they looked at him.

Snipe: It's no use! His power is on par with Y/N! We won't stand against him!

He said as Jack, now back on his normal form, slowly stood up, trying to disagree with his friend as he glared at Ryuga.

Jack: No! I won't just idly standby and let him win! I won't give up and let my friends lose! I have the power to protect anyone I care about!

Ryuga: Admirable, but pathetic. Your words mean nothing to them!

He laughed as Jack gathered his remaining strength to stand up as Ryuga is going for the kill.

Ryuga: You'll just be remembered as corpses!

He started to extend his arm again as dark flames started to shoot out of the Drag Claw as Jack wasn't moving, his fight isn't over, he believed that it wasn't over, that his will is stronger than ever before. Flames started to hit Jack as the 2 other riders stare at what their friend had received.

Orange flames started to appear as the spot of where Jack stood up started to fade as the secondary Kamen Rider looked at Ryuga.

Ryuga: What!!

Jack: I won't be beaten! I'll prove to you that our will is stronger than yours! Cross-Z Magma!

A bright orange knuckle started to materialize along with the Build Driver as an orange fullbottle was on his hand, placing the fullbottle inside the knuckle.

Magma Knuckle: Bottle Burn! 

He places the handle in front as he places the knuckle in the slots of the Build Driver.

Build Driver: Cross-Z Magma!

He slowly started to turn the lever of the Build Driver as he glares at Ryuga, who was still surprised at what is happening.

Build Driver: Are you ready?

Jack: Damn straight! Henshin!

Hot magma was poured down on a knuckle shape cement mixer as dragons started to emerge hardening themselves up as the knuckle started to punch them, breaking them down to reveal the final form of Cross-Z.

Having a bright orange colored armor that resembles like a dragon with obsidian black details that looks like hardened rock. Jack's will is truly stronger than ever as he unlocks his Final Form.

Build Driver: Gokunetsu kinniku! Cross-Z Magma! Achachachachachacha Acha!

Ryuga: No! This isn't happening!

Cross-Z Magma: Then you better start believing!

He said as he wasted no time in charging, having a new found will and power to destroy his enemies is now his strongest arsenal.

Leangle and Snipe followed suite, keeping his Advent busy as Cross-Z Magma attacks Ryuga.

Cross-Z Magma started to throw punches as hard as he could as Ryuga blocked them, making a good use of the Drag Claw to scorch him down, but to his surprise, it was no good at all.

Cross-Z Magma: Your dead!

He said as he kicks Ryuga on his knees feeling the power of his final form as Ryuga grunted in pain, throwing a desperate punch as Cross-Z Magma catches it, bending it to his will as Ryuga screamed in pain.

Back towards the 2 other riders, Snipe kept on shooting down Dragblacker as Leangle draws out 2 cards on his Leangle Rouser.

Leangle: Let's terminate this lizard.

Leangle Rouzer: Bite! Blizzard! Blizzard Crush!

He placed down his polearm as he jumps up and makes a twisted somersault as ice started to spray down out of Leangle as Snipe got ready.

Snipe: You're just a pain in the ass.

He said as he aimed his gun towards Dragblacker, pressing the gaschat on his side.

Gaschat: Kimewaza! Bang Bang! Critical Strike!

Ice started to engulfed Dragblacker as Snipe pulled the trigger, sending a massive shot at the dragon as Leangle performs a scissors kick, making sure to eliminate Dragblacker.

Cross-Z Magma kicked Ryuga away from him as he turns on the lever, having Ryuga staggered as he looks at Cross-Z Magma.

Ryuga: You think you've won? That's pretty cheap to think about it!

Cross-Z Magma: Say what you want, but our will, will never be broken!

Build Driver: Ready? Go! 

He jumped up as Ryuga, on his despearation strike, extends his arm again as dark flames started to shoot out of his Drag Claw, as Cross-Z Magma wasn't feeling its effect. He extends his leg as it started to engulfed in scorching flames.

Build Driver:  Volcanic Attack! Yeeeowch!

His kick connects as Ryuga flew a few meter away from him as he was now long gone. The 3 riders turned back to normal as they started to feel the fatigue catching up to them as they fall down on the ground.

Kado: Guess it's all up to Y/N now huh.

Senkai: Yeah. How are you feeling Jack?

Jack: Hot, like literally...

They let out a small chuckle as they slowly started to pass out from the exhaustion.

To be continued...
