Hello, dear reader, and welcome to this crossover between Highschool DxD and Furi. Now, first things first, HUGE SPOILER WARNING!

THIS FANFIC SPOILS THE ENTIRE STORY AND MOST OF THE GOOD QUOTES FROM FURI AND YOU SHOULD WATCH IT ON YOUTUBE OR PLAY IT YOURSELF FIRST.

Now that that tiny detail is taken care of, the reason this story came to be is simply the severe lack of Furi stories in general. So why not combine it with the only anime that's heavy on both plot and PLOT, if you know what I´m saying (wink-wink-nudge-nudge).

So, without further ado, let´s get going. Enjoy!

Rider looked at the Free World, taking in its beauty from orbit. He had fought hard for his freedom, and now, at long last, he could return to the Mothership. He found it rather hard to break away his eyes from the planet below, but once he managed to turn around, he saw it there, blotting out the sun. He started the thrusters on his gear, and flew right toward it. He looked around as he approached the opening of the core, and saw, in millions of tiny chambers, his brothers and sisters. Well, technically they were all the same, an unstoppable army made up of clones of the strongest warrior to ever have been born in their history. He arrived at the Core soon enough. As he entered, a big holographic head came into view. While floating before it, he saw a warm smile form itself on its face.

"Welcome back, Rider." The ship´s AI spoke, it´s voice echoing from the iron walls. Rider felt relief as those words registered in his mind, shaking him out of his thoughts. His long mission was over. In a few minutes, he would be allowed to rest.

"Uploading report…"

Rider closed his eyes and braced himself for the numbing sensation that usually follows those words. He waited. And waited. But nothing happened. Then the voice spoke again.

"Upload failed. Please confirm manually."

Rider´s eyes shot open. The upload failed…? That was impossible. He was part of the hive mind. The link between his mind and the Hive´s was…broken? He felt no connection. What had happened? Then it dawned on him, the fact that the rabbit was right. He had changed. No longer was he a mindless drone, seeking nothing but the completion of his assignment, but instead a truly independent being. It felt burdening in a way, knowing that he now had to bear responsibility for whatever he did. And yet for that very fact, he was thankful. He wanted the rabbit to live.

Rider now had a choice to make. Either he started the invasion to continue living with the Hive, destroying the rabbit´s life in the process, or he canceled it, making him the enemy of the Hive, the being(s) that birthed and raised him.

He was conflicted. On one hand, he had the Hive to thank for his life, but it was rather selfish, uncaring about him. He was just a foot-soldier, after all. To the Hive, he was disposable, if he stayed, he had no identity. On the other hand, the Guardians had locked him up and tortured him for who knows how long to give him the very identity he now possessed. After his talk with the rabbit in the Free World, and the trust he had shown in Rider, he knew he couldn´t just betray him. Him or his daughter. But still, he didn´t know what was right. As he thought on what to do, he remembered something. What that rabbit told him just before they escaped prison.

"We all have choices to make. We all have to decide what´s worth fighting for."

As he remembered those words, all of his doubts were washed away. He readied his weapons.

"Rider malfunctioning. Readying security protocols."

He would fight the Hive. Because the trust the rabbit had shown him was something he would want to fight for, to live for, to die for. The hologram had a frown on its face as two pairs of drones floated in, but Rider wasted no time. He immediately fired his energy beam from his right cannon, it´s light encompassing all four machines, instantly destroying them. The AI quickly activated it´s shields, preventing the core from being damaged, the bright energy being dispersed seemingly with no effort. Rider grimaced; that should have been the end. He couldn´t last very long against the huge arsenal the security system had installed, and its shield around the core was nigh impenetrable by any kind of weapon they handed out to their soldiers. He was interrupted in his thoughts by a barrage of bullets, which he quickly dodged with a dash right through them. Immediately following the first, another barrage was sent his way, leaving no time for strategizing.

"Why would you do this, Rider? We have always been here for you." the head spoke, though Rider ignored it, instead trying to figure out a way to disable the shields. Its power source was out of his reach, behind the shields itself, so destroying it was not an option.

"Why is their world worth more than ours?" it continued, as Rider continued to ignore it, focusing on another set of drones that had appeared.

"Do you think they would welcome you? No. To them, you will always remain a stranger. A danger." As his foe droned on, Rider realized what he had to do, and he readied his beam, aiming straight for the cooling system, which was right beneath him. He pulled the trigger, hoping that the Hive had not built another shield generator in the time he´d been locked up.

"You disappoint us, Rider." He blinked. The cooling system was undamaged, albeit not because of another shield. His shot had actually been intercepted by multiple other beams which easily overpowered his own, forcing him to dodge it at the very last second, feeling how it singed part of his hair. He had no chance anymore. His only way to destroy the core was gone, and his gear was running out of power, judging from the difficulty he had steering it. The beams were fired again, and he evaded them once more, though it was a very close call, one managing to hit the right wing of his gear, completely removing it and his arm encased in it from existence. He cried out in pain, twisting his face into a grimace as the AI smiled serenely.

"This is the end, Rider." it declared, no, stated as fact. Rider´s mind started to race. How could he get out of this situation? If he did not stop this right here, right now, the Free World would be destroyed. He thought back to all his past experience. He beat all the Guardians, in less than a day completely exhausted from the torture, he should be able to handle this!...right? Hold on, the Guardians? He remembered his struggle against the Burst, and realized that all walls crumble if hit by a big enough amount of energy. With a determined expression, he curled his functioning arm and raced toward the shields in a suicidal attack, prompting the cannons to adjust their aim. They fired. In that instant, Rider dashed away. Then, right as the beams hit the shield, he fired his own beam straight onto it as well, completely draining the last bit of power in his gear. As he fell, he saw the shield collapse and the core taking severe damage.

"Rider, we will annihilate you." he heard, and saw his opponent still floating there, preparing to fire a huge barrage of bullets, beams, every last thing in their arsenal, seeing as the cannons on every surface of the inside of the ship was currently pointed right at him. He was honestly surprised that they hadn´t activated the other clones yet, but even so, he would never be able to survive all of that, not without any energy in his gear. So he did the only thing he could think of. He pulled his right arm out of his broken wingsuit, having already regenerated, grabbed his pistol from his belt, and aimed carefully. Just as the first bullet was about to be fired, he pulled the trigger. And hit the exposed core with enough power to cancel any attack that might´ve been planned. He let out a breath he did not know he was holding, and watched as the ship started to explode. He felt tired, incredibly tired indeed after today, and just wanted to finally rest. He closed his eyes.

"You might have saved them this time."

Only to open them again in shock. His opponent was still alive, and even though the AI could no longer fight without its power-source, he was still on guard.

"But who will protect them next time?"

He blinked. That was true. He would have to take over that role as the protector next time, too. He raised his head, looking at his former superior with defiance.

"Because if you think that we will allow you to interfere again next time…"

Rider´s rebellious look turned into one of confusion. What was it talking about?

"…then you truly are a failure."

At that moment, he realized the cannons were still pointing at him. He would not be able to dodge that. In that moment, Rider accepted death. He waited.

"Rider, we will not kill you."

He was, once again, confused. He looked at the big face, which was starting to sound more and more static with every word, its flickering matching the sound.

"We cannot kill you. We will remove you from the equation differently. Farewell, Rider. This is the last time we speak."

Gone was the disappointed frown on its face, now replaced with an expression that truly scared him. One that was smiling weirdly, there was an emotion that he couldn´t decipher in it, yet, it was still so very neutral. Rider heard the cannons fire, and saw a blue substance quickly approach. He was not able to dodge it, and braced himself for the impact. As it hit him, he felt like he was ripped apart from the inside out, bit by bit. It hurt. It hurt so much, unlike anything he had ever felt before. Losing his arm felt like being bitten by a kitten compared to this. He couldn´t even tell how long it took for him to be whisked away, the pain completely numbing his senses.

A man with a rabbit mask looked up to the sky, seeing a huge detonation, and smiled. His trust had not been misguided, it seemed. He gently took his daughters hand, and went home. He would have to tell the others about their saviour.

As Rider opened his eyes, he was greeted by the sight of green all around him. After taking off his wingsuit, with some difficulty, he stood up. Looking around, he noticed that the floor under his feet seemed to crack and wither. He frowned. Was he back on the Free World? That can´t be right. He travelled across the whole planet to investigate its suitability for invasion (time very well spent now that he had rebelled), and he would have noted a forest with trees as odd as these. Then he noticed a large stone structure, with large wooden doors that were cracked open. Yep, this was most definitely not the Free World. He picked up his gear and ran inside, not wanting to corrupt the world he had just arrived on. From what he could tell, it was nighttime, anyways. As good a time as any to sleep.

Rider decided to sit down on one of the large benches that littered the interior. Everything that had happened today had worn him out to no end, like wringing the last drops of water from a dry towel. He needed to rest for a while, perhaps/absolutely longer. The second his body touched it, the bench turned black, however, Rider was too tired to notice, and fell asleep the second he closed his eyes.

Aaaaaand cut! That´s the first chapter all wrapped up. In the next one, I´ll have our friend Rider meet the cast of Highschool DxD, so stay tuned!

Since this is the first time I write a story, I would appreciate if you left a review. If you think it´s garbage, please tell me what I could improve.

Anyway, thank you for reading up to this point, and I hope you´ll return for more as the story continues! Bye!
