So, this got voted on my , and here it is, the first oneshot featuring Issei as different Kamen Riders!

To keep it simple, I'm sticking with the Hesei and Reiwa Riders as I know them better than the Showa ones. Also, I'll be going in order, so we are starting with Kuuga.

Don't be expecting any detailed plots or anything like that. These are more like snippets where issei turns into a Kamen Rider and then fights.

Also, I will admit I rushed this a bit as well. With all the crazy weather in Texas, I wanted to, I don't know, get some sort of payback. Get something good out of all the trouble this is casing me. And as a teacher, the effect of this weather on my work makes it even crazier for me.

I hope its good enough for you guys.

I do not own High School DxD or Kamen Rider.

Kuuga

"Would you die for me?" Raynare asked, a coy smile on her face. Before her date Issei Hyoudou could respond, she jumped back, throwing away her Yuuma disguise and revealing her older more mature Fallen Angel form. With her wings out, she floated above the fountain, relishing in the look on Issei's face. Interpreting it as a sign of fear, she chose to gloat a bit more.

"This date was fun, like playing with a dumb puppy." She taunted, floating down so she was sitting on the fountain edge. "Consider yourself lucky to have asome good memories for your final moments." She released a chuckle. "Good for you." A spear of light materialized in her hands, and she pulled it back, ready to throw. "Any last words before I end your life as a pathetic human?"

She hadn't really expected Issei to say anything, or at least anything coherent. Maybe some pathetic blubbering, even some begging for mercy. It would have really put the cherry on top of her plan.

"Honestly," Issei spoke up, scratching his chin. "I'm feelings a mix of relief and confusion." This threw Raynare so off guard, she didn't think to attack while he was talking.

"On one hand, I'm glad to know that I was right when I suspected you of not being human." This made her jaw drop. He was aware of her true identity? How!

"On the other hand, I've never encountered something like you before, or heard of anything like you. I'm more used to my enemy looking more like monsters, not people with wings attached."

"Excuse you!" Raynare screeched, unable to take any more of this. "I'm a Fallen Angel you nitwit! Not some wimpy human with wings! And I'm going to kill you!"

"Well that would be problematic." Issei sighed, straitening his back. "I was hoping I could ask you some more questions, but I'd rather not die. There's stil a lot I can do the help the world out." He gave the Fallen Angel a smirk. "So I'll have to deny your request."

"As if you have a choice!" Raynare nearly screeched as she threw her light spear. Issei dodged to the side with ease and dodged the ones that came after. By the time her initial barrage had finally ended, Issei had increased the distance between the two of them.

"Well even if I don't have a choice," Issei said, standing upright and brushing himself off a bit. "I'll decide my fate myself!" He declared.

He brought his hands down to his waist, his fingers forming a triangle shape. All of a sudden Raynare detected a pulse of magic as a swirl of energy forms around his waist, solidifying into a belt with large circular sides and a large silver buckle with some lights on the side and an orb in the center. Then, he moved his left arm to the side, and extended his right arm diagonally palm facing forward.

And he uttered a single word.

"Henshin!"

His right hand moved over his left hand, and pushed it down, pressing on the circle on the left, which caused the orb in the center of the belt buckle to turn red. Raynera felt a wave of power as armor quickly formed over Issei's body.

In only a few sencds, and armored warrior stood in his place. Black body suit with red armor on the chest, shoulders, wrists, and feet.

The helmet was also unique. The mouthguard part looked like an actual jaw, with large red bug-like eyes. To top it off, a set of horns adorned the top like a sort of crest.

Raynare could not believe what she was seeing. Issei Hyoudou was supposed to be a normal human with a dormant sacred gear, not some transforming warrior with magical powers based on what she was feeling from him now. On top of that, she started to feel like he was still holding back, and that pissed her off. Not only did she fail to sense anything like this from him despite direct contact, it was as if he was saying that the power he was giving off now was enough to defeat her.

"Who the hell are you!" Raynare screeched, spears of light manifesting in both hands.

"Kuuga." Issei replied, his voice from the mask more confident and radiating its own power. "Kamen Rider Kuuga."

With that, Issei jumped forward, closing the distance between them so fast that Raynare barely had time to block a punch with one of her spears. She had hoped it would cut through his hand, or at least burn it, only neither one of those happened. Growling in frustration, he tried to stab with her other spar, only for issei to dodge the attack then counter with a kick.

This pattern kept repeating itself. Every time Issei struck first, Raynare either blocked or dodged, but her follow up was countered. Even when Raynare tried to go on the offensive, issei easily dodged her thrusts and strikes and took advantage of the openings to deal even more damage. After several repeats of this, all Raynare had to show for her efforts were cruises all over while issei barely seemed winded.

Growling in frustration, Raynare spread her wings and took off into the sky, throwing down her spears in an attempt to hit Issei from above while gaining altitude. However, that did not work out. Instead, issei jumped into the air himself. While he did not reach as far as Raynare did, he was high enough, and in just the right spot, to step on the spear of light, and jump again! By the time she realized this, Raynare had already thrown enough Light spears down for Issei to use as footholds and in moments he was actually above her. This position allowed him to spin in the are and deliver and axe kick right on her back where the wings came out, sending her crashing into the ground.

She landed so hard, not only did she create a small crater, her wings were broken. As she struggled to get up, issei landed on the ground a bit away from her, and turned to face her. He just stood there, watching the entire time as she forced herself to her feet. Raynare could hot help but growl in anger.

"Who the fuck do you think you are!" she screeched, spitting out blood as she spoke. "I'm Falen Angel, and I'm destined to stand by the great Azazel. A mere human like you, even with some fancy armor, can't hope to beat me!" with that, she put both hands tighter and started creating a Light spear larger than the ones from before. She planned to end things with one strike.

So did Issei.

He got into a stance, leaned forward on one leg, then charged forward, power radiating off his feet. When he got close enough, he jumped into the air, flipped around, and kicked towards Raynare. That was when she threw her charged spear of light at him.

Their attacks met right in the middle, Issei's kick hitting the tip of Raynare's spear, waves of power rippling across the air. For a moment, it seemed like an even match, and the Fallen Angel allowed herself to grin. This could give her a chance to escape!

But less than a second after that thought, Issei's kick tore through the spear like paper, continuing towards the target and hitting Raynare right on her exposed stomach, sending her slamming into the ground once again while Issei flipped backwards and landed in a crouched position.

As Raynare struggled to breath, she felt something wrong. It was as if some foreign energy was invading her body, deteriorating everything it touched as it spread. With great struggle, she managed to lift her head enough to see a strange emblem right where Isseis' kick landed, burning on her skin. From there burning veins of energy could be seen spreading over her skin, and Raynare could feel her end approaching.

"No!" She screamed. "This can't be happening!" She turned to Issei who was still in a crouched position, but facing away from her. "Please!" She pleaded. "Please spare me!" Issei did not respond at all. "Please!" She begged again, reaching out with her hand towards him only to see the destructive energy burn across it as well. "No!" She cried out, before the energy consumed her and she exploded.

When the explosion and fire died out, the only trace left of her were ashes, and black feathers.

Issei finally stood up, and the armor around him disappeared as he turned to face the spot where his date died. With a sigh, he rubbed the back of his head as if embarrassed.

"Why is it so hard to meet a nice normal girl?" He asked aloud before walking off.

Okay.

Hope you liked it. I just want to play around a bit with Issei as different Kamen Riders. Not really going to go deep on the story or anything like that. Just me having some fun.

That's it for now. Please Favorite, Follow, and Review. But most of all, thank you for reading!
