Shortly before Asia got the game disease…

"I don't know what it is about that blonde nun… but something attracted my attention…" Saki, who had been curious about Asia and had followed her, muttered and watched her from behind a tree.

"Saki, what are you doing here?"

"Graphite, there's a girl I'm a little curious about…"

"What do you mean you're curious about… that's! Snipe!? Oho, interesting!"

"Hey, wait a minute, Graphite, let's observe a little more."

Saki stopped Graphite when he tried to intervene in the fight after seeing Snipe.

"Uuh… m-my head… it hurts… my head… n-nooo... AAAAAAAAAH!"

At the same time as Asia screamed, a large number of particles appeared from her, and those particles turned into Aranbura Bugster.

"That's… our comrade!?"

"I see… I don't know why exactly, but the virus is mutating… I'd say Level 5-7… well, that's it, Graphite, what do we do?"

"What is known, let's go, Saki, let's welcome our new brethren."

"Huh, that's the spirit."

Saki then snapped her fingers, changing her appearance from the plain clothes she had been wearing to a purple skirt and a light blue shirt under a knee-length asymmetrical coat that looked like a female version of Parado's outfit.

"What's with the getup?"

"If I keep dressing like earlier, people will know who I am. And Graphite, while I'm in disguise, please don't call me Saki."

"Okay… then what should I call you?"

"About that… then…"

Saki put on a red and blue mask and said, "You can call me Paradox for a while…"

Present

"What the hell is she…?"

"What!? What is going on!?"

"Kamen Rider Para-DX Level 50…"

Issei and Raynare both screamed in confusion, while Garagaranda, who knew the Kamen Riders, muttered when he saw Para-DX.

"Well then, Kamen Riders, let's play." Paradox said, and was about to start attacking.

"Wait! I won't let anything happen to Asia!"

"Let's become allies for now!"

Garagaranda and Issei stepped in and told the Kamen Riders. At the same time, Issei's left arm glowed and a red gauntlet appeared.

"Ooh, Issei, your Sacred Gear… it's the Boosted Gear, I heard it's a dangerous Sacred Gear, but it doesn't matter!" Raynare said, looking at Issei's gauntlet.

"Yeah, that's right! But I'll protect Asia!"

Meanwhile, while he was talking…

"Heh? UAGH!"

"H-hey! Ugh!"

Issei and Garagaranda were both grabbed by Brave and Lazer respectively and thrown backwards.

"W-what's the deal!?"

"Get out. I'm not letting some amateur interfere with my operation."

"But we…!"

"Oi, oi, did you forget what I told you the other day? I told you that you would fail if you acted on your emotions, and to listen to adults, right? You had one job, kids, one job."

Brave and Lazer berated them.

"Yeah, well, you two are getting in the way of the game, so… I'm afraid I'm going to ask you to leave." Para-DX said and held up one hand.

Then…

"There's energy items in the air…"

"What's the meaning of this…?"

"What the hell is going on…?"

Brave, Snipe and Ryugen muttered as a large number of energy items floated in the air. Para-DX then began to move them around like a puzzle.

"Let me explaining my power. Perfect Puzzle allows me to manipulate and combine things and energy items in the Game Area at will, just like this!"

Teleport!

Teleport!

Then two energy items flew towards Para-DX and popped in front of her. Para-DX pointed her fingers at Issei and Garagaranda.

"You."

"Me?"

"You."

"W-what?"

"Get out…"

As soon as she said that, Para-DX snapped her fingers. Then Issei and Garagaranda vanished instantly.

"W-what the!?"

"Those two are gone…?"

"Yeah, I just used the energy item to teleport them to another place."

"What?"

""WAAAAAAAAAAAHHH!""

Issei and Garagaranda were teleported to the top of Kuoh Academy's pool, and the two of them fell straight into the water.

"Well then, let's get this show on the road."

"All right, now that they're out of the way, we can concentrate on the operation!"

DRAGO KNIGHT HUNTER! Z!

"Examiner, Schoolgirl, I need your help!"

At Brave's words, two virtual Gashats appeared.

"Of course! Now we're revving it up!"

"I don't like you, but…"

BLADE!

CLAW!

GUN!

"Skill Level 5!"

"Fifth Gear!"

"Tactics Level 5!"

Gachan! Level Up! Do-Do-Drago! Na-Na-Na-Knight! Dra-! Dra-! Drago Knight Hunter!

Brave!

Lazer!

Snipe!

"We will now begin the operation to remove the Bugster."

"Let's start!"

"I'll crush you first before going to Graphite!"

"Let's go!"

Brave Level 5, Lazer Level 5, Snipe Level 5, and Ryugen shouted as they headed towards Para-DX.

And then…

"HYA!"

"ORYAA!"

Brave attacked Para-DX with his Drago Knight Blade and Lazer with his kick, but she easily caught the attack.

"HA!"

"GAAH!"

Brave was hit.

"Whoa!"

"Crap!"

Lazer was kicked and knocked backwards.

"HAA!"

"ORAA!"

Next, Snipe and Ryugen tried to shoot at Para-DX. However…

"Useless."

Steeling!

Para-DX chose the steeling energy item and defended herself against their attacks.

"Well, let's see… errr, this and this."

Muscle Up!

Speed Up!

Jumping Up!

"Okay, now's your turn~"

With that, Para-DX headed off to attack Snipe and Ryugen. The two attacked back, of course, but…

"S-she's too fast!"

"She's using high speed energy item!"

All of their attacks were avoided.

"UAAH!"

"KYAA!"

"GAAAHH!"

Ryugen, Snipe, and the nearby Lazer were blown into the air by Para-DX's high-speed attack.

"It's finisher time."

Para-DX turned the dial on her Gashat and activated the finisher.

Kimewaza! Dual Gashat! PERFECT CRITICAL COMBO!

"Ha!"

"UAAAAAAAAAGH!"

"AAAAAAH!"

While Snipe, Lazer, and Ryugen were blown midair, she unleashed a series of kicks while moving freely and fast in the air, forcing the three of them to untransform.

"No way… she's completely beyond the power of us fallen angels…"

"Heh, way to go Sa-, Para-DX, you're no match for those Kamen Riders…"

Raynare and Graphite commented as they watched the fight in front of them.

"Damn! So this is the power of Level 50…"

"She's too strong…"

"I mean! Using energy items at will, that's cheating! It's too unfair!"

On the other hand, Kiriya, Mitsuzane and Nico were struck by the power of Level 50 and cursing to themselves.

"No, no, I think you guys with Cronus on your side are cheats enough." Para-DX deadpanned to Nico, and then turned to Brave. "Now… Brave, it's your turn… that's…"

Para-DX stopped and stared at the Gashat that Brave was holding and muttered to herself.

"If you're going to do that… then I'll play my trump card…"

In Brave's hand was a pure white Gashat.

"What's that Gashat?"

"That's Taddle Legacy… no, Prodigy! You're not ready to use it yet!"

Nico and Kiriya gasped at the sight of the Gashat.

"Hahahaha, I didn't expect to see a Level 100 Gashat so soon. Okay, Brave, you can use it, because the harder the game is, the more it gets exciting~"

"Fine, then… Skill… Level 100!" Brave shouted, and was about to press the activation switch of the Gashat.

But then…

Lock On! Melon Energy!

"Uh? AAH!"

With the announcement, an energy arrow struck Para-DX, and at the same time, Zangetsu Shin and Duke appeared in front of the Riders.

"Brother!"

"Mitsuzane, you've done well, leave the rest to us."

"A Level 50 Rider… how curious."

The two of them said.

"Zangetsu Shin… Duke… I'm not excited…"

And with that, Para-DX turned the dial on her Gashat Gear Dual the other way.

KNOCK OUT FIGHTER!

…The strongest fist! Round 1! Rock and fire! …The strongest fist! Round 1! Rock and fire!

"Dai Henshin."

Dual Up! Explosion Hit! Knock Out Fighter!

Para-DX's helmet twisted, the pattern on her chest changed to displaying a fiery pattern, and finally the armor on her shoulders detached and reattached on her arms to form giant red knuckles.

"She changed form?"

"Fighter Gamer Level 50… come on, you've made my heat boiling… you'll be my opponent!"

"Hiiro-sensei! We'll take care of her! You fulfill your mission as the doctor!"

"Understood…"

While Zangetsu Shin spoke to Brave, Para-DX closed the distance towards him and Duke. Para-DX, who had set her sights on Duke first, approached him while dodging Duke's Sonic Arrow, and was struck the moment she stepped right in front of him. He was startled for a moment, but Duke still got up and tried to slash Para-DX with his Sonic Arrow.

However, Para-DX easily blocked the attack with her knuckles. But still, Duke put a lot of power into his attack and yelled, "The power of my Driver is the power of the world! It cannot be defeated by the likes of you… the Bugsters! My invention is the truth of the world!"

"That kind of power is just a theory, the real power is within these fists!"

Para-DX then hit Duke with a series of powerful blows that sent him away.

"No way… what destructive power…" As Duke crashed into a nearby fountain and untransformed, Ryoma muttered before fainted.

"Ryoma!"

"You're next… Zangetsu!"

Para-DX then rushed at Zangetsu Shin and tried to hit him with an attack.

"You might have defeated Ryoma in an instant… but it's not the case for me!"

With that said, Zangetsu Shin skillfully avoided Para-DX's punches, and when he saw an opening, he fired an arrow from his weapon. Para-DX also managed to avoided Zangetsu Shin's strike by a slim margin, and the battle was truly even.

"I'm supposed to be superior to him in terms of performance, but… as expected from Takatora Kureshima, even though it's from another world… what he lacks in performance, he more than makes up for in skill…"

"So this is the power of Level 50… the numbers are justified…"

The two of them muttered as they sizing up each other.

Meanwhile

"Bugster, I'm cutting you down!"

"Hmph, let's see if you can do it!"

Brave, in order to fulfill his mission as a doctor, was about to perform an operation to remove Aranbura while Zangetsu Shin was stalling Para-DX. Then…

"Brave… I'm not letting you harm my brethren!" Graphite declared, standing in front of Brave to defend Aranbura.

"Graphite… I don't have time for you… but if you try to interfere with my operation I'll cut you too, even if it costs me my life!"

"Interesting! I'll be your opponent!"

Graphite took out his Bugvisor and tried to transform.

However…

"Gah! What the!?"

"This attack… it's him!"

Zangetsu Shin and Brave, startled, looked at the direction the attack came from.

"Ladies and gentlemen, I apologize for the excitement, but we must suspend the battle."

There was Genm, carrying Asia. He looked at Raynare and spoke.

"I know what you're up to, fallen angel, and your plan is something we can help you with."

"Ha!? I don't know who you are, but you're talking to me, a supreme fallen angel—"

"SILENCE!"

Genm fired an energy bullet that grazed Raynare's cheek.

"Which is it!? There are two options for you! We can easily deal you here! Come on! Choose! Either you let me delete you right here…! Or you can carry out your plan!"

"A-alright… I'll take your help."

"Good!"

Raynare decided to go along with Genm's offer.

"Hmpf, disappointing… Oh well, Brave, next time we meet, you better use that Level 100 Gashat properly."

And with that, Para-DX turned into particles and disappeared.

"Let her go!"

"Wait! Let go of the patient!"

Brave shouted to Genm, but at that moment Genm fired a barrage of energy bullets into the area, stopping him in his tracks. And when the dust dissipated…

"They're gone…"

Genm, Graphite, and Raynare were all gone.
