Author's note:

I was originally going to include this part in the last chapter, but it would have made the chapter too long. Not to mention I didn't want two reveals to be made in the same chapter. So think of this as an extra chapter, extra material that couldn't be included in the season finale. Also, since this chapter is being published a day later, I might not be able to include all reviews but I will read them!

Reviews:

Guest DCDGojira: Happy you liked it!

lordri25may2001: I'm happy you liked it! As for Abyss' identity, don't worry that will be revealed soon. Whether it's Kuroiwa or not, I can't say, but I can tell you now that I haven't forgotten about him. He'll show up. Right, since these guys are going to be the villains of the next season, they'll have connections with Carol and her group, that's why Abyss referenced Garie. I like the suggestion about the demon slayer thing, but I think I like the Einherjar thing way more since it aligns with something I'm planning later on in the seasons. Something that needs Symphogears' songs to stabilize the power. Or something like that, I haven't thought of the details yet since we're way too early for that. I was thinking of some girls being into Hajime and him just being freaked out by it. He's not dense but he doesn't know how to respond, given how long it took him to confess to Hibiki. We'll see who. But yeah, I'll try to finish the story. We're already 2/5 done and I plan to make it to 5.

Slimereader11: I'm happy you enjoyed it. You won't be disappointed with GX.

Nexus240: I'm glad you think so. I try to make it a bit more dramatic and engaging to make it more interesting than simple good vs evil. What happened to Ryuga and Femme? Well, here's your answer!

Lost Files - One
The Divine Disasters of Valhalla

The first thing he felt was a numbing pain in his body. The second was whatever hard surface he was laying on. But that couldn't be right. The last thing he remember was a sphere of fire inches away from killing him. He sat up with a gasp, frantically glancing around.

Terunosuke instantly flinched, holding his aching sides. From what he saw, he was in some sort of a cave, with a huge hole in the ceiling letting some sunlight in.

"Hey. You. Finally awake?"

The black-haired man turned to see a young man with a feminine face laying next to him. He was leaning against the wall with his leather jacket over his legs, leaving him only with a plain white shirt."Who...?"

"I'm surprised you didn't die back then." Allister mused, his own body covered in bruises."I thought you had killed yourself back on that cruiser or drowned."

"You're...you're Ouja!" Terunosuke stirred and winced in pain, the sudden movement causing his wounds to act up.

"Calm down. Feel free to call me Allister Albedo. No need for a professional name this time. Also, you were trying to kill me too." Allister quirked a brown, stifling a chuckle."Besides, we're already dead. This is hell."

"Huh?" Kuwana perked up at that."We're...dead?"

"Sure. I mean, I know I died, courtesy of Section Two's Riders." Allister patted his left cheek."I mean, how else would you explain us ending up in this unknown place, when we were so close to death?"

"B-but...I can't be in hell! I did nothing wrong!" Kuwana crawled over to Allister, grabbing him by the shoulders."Did Jades die?! Did he cry in despair as his life was ripped away from me?! Did he suffer a slow and painful death?! Did you rip him to pieces like he deserves?! Did he-"

Allister grabbed a pressure point on his shoulder, prompting Kuwana to release him and fall on his rear upon feeling the paralyzing pain."Sheez. I don't know how you did it, but you seem so pitiful that I can't lie to you. Calm down. We're not dead. As for whether this is hell or not, that has yet to be seen."

"So...we're not dead?" Terunosuke blinked, puzzled."Then, how did we-"

"Hey, he's awake now! Why don't you explain everything to him?"

"I'm not explaining that whole thing again, damn it!" A loud voice echoed through the cave. They waited for a female to make her way toward them, her appearance becoming visible as she got closer to them. A young girl with short lilac hair, mustard-colored eyes, and a Lydian uniform, swayed her hips as she approached them, a deranged smile on her face."I only told you because I was bored. But repeating myself...isn't very tempting..."

"Who the hell is this bitch?" Terunosuke asked Allister, only to have her grab his chin, forcing him to look into her eyes."What the fuck?!"

"Did you forget about me, Onii-san?" The girl's eyes dilated, licking her lips."Should I call you Ojii-san instead since you're quite older than I expected?"

"You're...that girl pretending to be me! You're Femme!"

"Ah~! I'm so happy!" She squealed in delight, her cheeks flushing."You remembered me! I love it when people remember me! But you guys can call me Nakahara. Nakahara Chiaki. At your service. But I didn't pretend to be you. I just...used your MO to cover up my killings."

"So that serial killer...it was you all along? A little brat?"

"You shouldn't be so surprised, Kuwana-san." Allister quipped."You started your killing spree when you were fairly young too."

"Apparently that's become public knowledge now." Terunosuke sneered, his gaze shifted to the girl and glaring at her skeptically."So, you saved us? For what?"

"No, I didn't..." Her voice suddenly lowered in pitch, her energy gone."I am just...here to take you to my master..."

"Master?" Terunosuke parroted.

Allister stood up, moaning as his sore body was forced to move again."Going to sleep all day? Or do you want to get some answers too?"

Chiaki offered her hand for Terunosuke to take.

"Like hell I'll let this stop me." Terunosuke snorted, swatting her hand away, getting up on his own with great difficulty.

"So cool." Chiaki giggled before she scowled."Don't act like you're tough shit, you dog!"

"What's up with her?" Terunosuke asked Allister, who shrugged in return.

"She's very interesting. Her emotions are all over the place. I genuinely can't get a read on her." Allister rubbed his chin."Fascinating. She's brimming with emotions of all different colors."

"Colors...? Great, I'm surrounded by freaks." The group descended their way down a set of stairs that took them deeper underground.

"You say that, but you're a freak yourself." The lilac-haired girl retorted."Willing to go with an organization where they were experimenting with children just because you wanted to be special? That's just plain sad."

"Shut your mouth! I worked very hard for my accomplishments!" Terunosuke exploded."I'm the best! I'm supposed to be the one!"

"Shut the fuck up, you whore!" Chiaki barked back, baring her teeth."If you talk to me like that again, I'll bite your fucking spleen out!"

"Now, now." Allistered step in between them, separating them."Kuwana-san, why don't we listen to what she has to say?"

"Her? You mean this master of hers." Terunosuke scoffed. After a few minutes, they finally made it to the bottom of the stairs, entering a gigantic area underground. The stairs led to a giant rock platform in the form of a circle. There were carvings on the walls that made no sense. Just things that looked like monsters or demons. The painting of a snake covered all the walls, eventually connecting to what looked to be the sun as the snake was about to devour it. Next to it was the painting of a giant dog and what looked to be a human. Though the person in question was divided into two. One side looked human while the other looked like it was decaying.

"I brought them," Chiaki announced to the figure ahead. Hazuki Kaburagi was standing in front of an altar containing a huge black sphere. He looked over his shoulder, one of his eyes gold. He wordlessly made his way over to the group, holding what looked to be a stuffed penguin in his hands.

"Good work, Chiaki-chan." The boy nodded at her, prompting her to fidget in place. He regarded the duo in front of him with a smile."Welcome, my brethren. I've been expecting you."

"What the fuck is this?" Terunosuke looked stupefied."What, is this a joke? This is the person who saved us?! Another kid?!"

"That "kid" is Kamen Rider Ryuga." Allister's lips thinned in a line."And yes, it's him."

"Let him explain..." Chiaki muttered, though her eyes looked like she wanted to tear Terunosuke apart."Loki-sama is talking."

"Loki?" Allister quirked a brow.

"At ease, Chiaki-chan." Loki, who was possessing Hazuki's body, rose a hand."I know you're all confused as to why I saved you. And how I saved you. Well, let's start with the how. I was present in the battle on those carriers. I was fighting against Miku Kohinata, who had been forced to use the Shénshòujìng. But after freeing her, I made my escape. Though I never really left. I stuck around, watching from the shadows. I watched as you two were cornered by Section Two and the Nephilim. I apologize for waiting until the last minute to warp you. I didn't want them to realize that you were saved."

"Warp?" Terunosuke repeated. Loki manifested a portal in front of him, passing his hand through it. A portal opened up in front of Terunosuke and from it, Loki's hand came out, waving at him."You can teleport..."

"It's not absolute quite yet. I can only teleport to places I've been. Which is why it took me a while to act." Loki pulled his hand back, closing the Calamity Gate."That's how I saved you. And now Section Two thinks you're dead, which will let you move freely for a while."

"Those portals are incredible. Gave me quite the trouble when we first fought back then." Allister said with fascination."Not that we're ungrateful for your assistance, but why save us? Unless you have something planned for us."

"If you think I'm in your debt because of that, you're dead wrong." Terunosuke seethed."I'm done working for organizations."

"Work for? Oh, please. None of that." Loki chuckled."I saved you, yes, but not because I want to use you. I want to work with you. Work together for the ultimate goal."

"Work with you?" Allister asked."What do you mean?"

"I haven't introduced myself yet, have it? Allow me. My name is Loki. But I am currently using my partner's body. His name is Hazuki Kaburagi, but you can call him Haz. He's my human host as well as my closest associate."

"Wait...what?"

"Let me show you." Loki set the plushy down, concentrating and injecting his essence into it. The plushy came to life, his eyes shining in gold. Hazuki sighed, his eye returning to his normal pink."See?"

"How...?" Terunosuke gaped. Even Allister was taken aback, unfolding his arms in shock.

"I am a God. Loki, the God of Mischief. Among other things I'm sure you've heard in your history classes or whatever." Loki flapped his cotton wings."This here, as I said, is my partner. He's Ryuga."

"I was shocked to find out Ryuga was a high school student." Allister commented."You have quite the record of killings. I heard you wiped out all of the Yakuza in Japan."

"I helped too." Chiaki rolled her eyes.

"Someone had to kill those criminals." Hazuki grumbled with disdain."I just happened to be the one to do it."

"What the fuck?!" Terunoke yelled, catching them by surprise."How are you so acceptant of this, Albedo-kun?!"

"Are you serious right now?" Allister arched a brow."You do realize that we're fighting using supernatural abilities to get a wish granted by a being known as Odin, who also happens to be a God. This shouldn't be so surprising."

"I'll tell you all about that later. It's complicated" Loki said."Aren't you more eager to know why I want you to work with us?"

"Work with you how? And why?"

"Because our goal is to eradicate all evil from this world." Hazuki chimed in."To purify it and cleanse humanity and save them from eternal damnation."

"Eradicate evil?"

"Humanity is destined to die by their own hand." Hazuki continued without missing a beat."It's too late to save them. Because everyone has the potential to be evil. All the atrocities going on in the world is because evil has such a strong grasp on humans that it's become normal. It's too late to stop it. People will continue to die because of evil and humanity will suffer slowly for centuries before they die off completely. Kids are dying every day without ever realizing their dreams. Adults are watching their children die without being able to save them. People kill for the fun of it and even pay for it. This world is rotten to the core because humans are destined to be evil, because of the Creator. And the Curse of Balal.

"In the United States alone, home of the brave and the privileged, approximately 597,689 people will die from heart disease. 574,743 will die from cancer, 138,080 will die from respiratory diseases, 129,476 from stroke, 120,859 from accidents, 83,494 from Alzheimer's..."

Chiaki flinched slightly, but Allister had seen it from the corner of his eye. He decided to dismiss it and listened to Loki.

"69,071 from Diabetes, 50,097 from Influenza and Pneumonia, and 50,097 miscellaneous syndromes. Not to mention the ones killed by the Noise." Loki finished, taking a deep breath."This is according to our calculations, of course. As you can see, a lot of people are dying in America alone due to disease. Their lives are being cut short for things they can't help. Ending their dreams. But what about things caused by humans? Like the Superstar said, people killing others. 16,259, if I'm not mistaken. But what about the ones that slip through the cracks? What about people who see no other choice in life but to end it? Starvation, wars, natural disasters. People kill each other for power, religion, resources, money, land, politics, and simple pleasure. Humanity is well on its way to its ultimate demise."

"But this process will take centuries." Hazuki picked up where he left off."An agonizing end for the human raise. And things will only get worse."

"So let me guess, you want to be the heroes who saved humanity?" Terunosuke didn't seem amused."That sounds like childish aspirations. There's no way to do that. Humans will continue waging war with each other and people will still die. Do you even have a plan for this so-called ambition of yours? How do you plan to prevent humans from killing each other and eradicate evil as you say?"

"Of course. A goal with no plan is merely a delusion, after all." Loki chuckled upon hearing that."And the solution for that is to wipe out the entire human population."

"Wiping out...the whole human population?" Allister's eyes widened.

"Wait, so your solution is global genocide?!"

"I mean, it's not like they'll stay dead forever. They'll be revived. Like we said, humanity is doomed. There is no salvation for them. So the best thing to do is put them out of their misery and cleanse their souls with death. However, this is necessary for them to be purified from all evil and be reborn in our new world."

"The world we'll create using the wish granted to us by Odin." Hazuki carried on."Once all humanity has been reduced to nothing, we'll use that wish to create a new world. One freed from the chains of God and where humans can be truly free and be happy. Where no pain or suffering exists. A perfect world reigned over by a single, undeniable, ultimate good. A perfect world free of all evil."

"You...you guys want to rule over that world?" Terunosuke whispered, but they were able to hear him.

"To make sure evil does not arise again, the Ultimate Good will rule over the people and keep them safe from temptation." Hazuki placed a hand over his heart."I will make sure that everyone gets to live the life they want. Where they don't have to lose loved ones or suffer. But for that, we need your help."

"But by normal standards, we're evil." Allister pointed out."Anyone you ask will tell you that. We've killed people for money, pleasure, and revenge. And you want us to help you achieve this...perfect world? Kind of weird, don't you think?"

"I realize that good alone is incapable of making that dream a reality." Hazuki stared down at his hands."I've also committed countless murderers with my own hands. And if this plan works, then I'll have the whole world's blood on my hands. But I'm willing to do it if it means saving humanity from eternal damnation. I chose you guys because, like me, you stop at nothing to achieve your goals. This plan requires people willing to do what it takes, no matter how immoral it seems. Sometimes to do some good, you have to be the bad guy. Also...I can understand you and your motivations."

"Understand us?"

"Allister-san, you want to see the strongest emotion created by the strongest goal. Because you lack human emotions. Kuwana-san has a vendetta against his siblings. But all of that happened because of things out of your control. But imagine a life where none of that happened. Where you're happy and you can do whatever you want. I can make that happen. I can make you get the things you want in our new world. And you can be part of that change."

"Hold on. For that, you have to get that wish." Terunosuke cut him off."And Odin said that the Rider War will only end when only one Rider stands at the top. Are you suggesting for us to just let you kill us?!"

"Think of it as a necessary sacrifice." Loki reasoned casually as if he were talking about the weather."Of course, we're not asking you to just die now. No, no. We'll save that for later. You guys have targets, right? People you want dead. One last trip on the sinful train before all evil is vanquished. But don't worry. Because once the plan is fulfilled, you'll be revived along with all the people you care about. You'll be reunited with them. You'll get to live the likes you WANT. Not the ones dealt to you by this cruel destiny."

"I'm in." Allister rose his arm."Back when I was facing that blast...I could feel the emotions radiating from that boy, Hajime Adachi. His powerful emotions were so strong, they were more blinding than the attack itself. But when I look at you, Haz-kun. I see an even stronger emotion. And it's directed toward a great goal. You are willing to kill all of the human race to save them. It takes an incredible amount of determination to do that, to say the least. I want to see more of your ambitions. And see where your emotions take you."

"Are you serious...?" Terunosuke watched in awe as Allister and Chiaki stood next to Hazuki and Loki."You can't be serious! I'm not just going to die for your damn dreams! This...this is just-"

"Don't you want to see Serena again?" Loki asked, silencing the young adult.

"W-what...how do you-"

"I can demonstrate to you that we're not playing around. Superstar, if you would."

Hazuki took Loki's essence back into his body, his left eye turning gold. He made his way over to the black sphere in the center of the altar, touching it. The sphere began to glow in a blue light, showing countless souls moving inside of it."This is what we're using to collect human souls. You see, for us, there is no consequence in death. Every time someone dies, this artifact absorbs their soul and absorbs it. For the most part. There has been something pulling souls from us for quite a while now but we have yet to determine what's causing it. So, unfortunately, not everyone will see the new world. But we can worry about that later. Anyway, when a person dies, their soul ends up here, the Sea of Souls. It also works as a reactor of sorts. Once we fill it with enough souls, we'll be able to start with our plan immediately. But human souls can only power it so much. However, as it turns out, Kamen Riders and Symphogears power it up even more."

"All of those...things..." Terunosuke's eyes were glued to the giant sphere, watching as countless souls swam around."Are people...Wait, you said Symphogear-"

"Their souls. Not their consciousness." The God corrected, abruptly cutting him off with a sly smile."Can't have a consciousness without a body, after all. We've been collecting these souls for almost 10 years now. So I'm sure you'll like what I got in store."

From the sphere, one of the souls began to take the shape of a young girl all too familiar to Terunosuke."Serena!"

The holder of the Gai Deck rushed, his hands trying to reach out to Serena, but the glass kept them separated."Serena!"

The girl attempted to touch his hand through the glass before her figure was submerged back into the Sea of Souls. Terunosuke fell to his knees, defeated.

"You can see her again." Loki marched up to him."In the new world. I promise you, if you dedicate your life to our cause, you will be reunited with her. You'll get to live the life you want with her. She won't have to die by something out of her control. She'll live her life as she wants to."

Terunosuke's forehead rested on the glass, his eyes shut as tears streamed down his face.

"Or you can just turn away from this. I can warp you back to your home. But we'll be forced to kill you nonetheless since we'll be enemies. Either that, or you'll be caught by Section Two and most likely executed anyway. Remember, you are a wanted fugitive now. And Section Two has now 6 Kamen Riders and 6 Symphogears. Do you think you can fight that amount of enemies?"

Loki whispered in his ear."And I can give you power. The power you need to get revenge on the person that outshined you. You'll be strong. Stronger than your enemies. All you need to do is accept my deal. What do you say? I'm sure Serena will thank you for it."

"Serena...Looks like I'll have to make a deal with the devil after all..." He muttered to himself before looking Loki dead in the eye."Fine. I'll do it. I'll help you change this world. Because that's what Serena would want. And she deserves more than this."

"Good." Loki smiled widely."Then I'll grant you power. Allister, come here too."

Allister stood next to Terunosuke, as both of their heads were touched by Loki's hands. They felt a sudden surge of power, subsequently followed by agonizing pain that forced them onto their knees. They both screamed in bloody murder, black veins forming across their bodies and their scleras turning pitch black.

Once the process was done, they were both panting for air, their chests heaving, holding their heads as they felt they would split open.

"I gave you a "Seed". It might not seem like much, but with care and time, they will bloom along with your powers. You'll get stronger over time."

"How the hell do you even plan to wipe humanity out anyway?" Terunosuke's already dark eyes, mixed in with his black sclera, made it look like he had no eyes.

"Even with our powers as Kamen Riders, it's still only 4 people against the world." Allister pointed out."It will take a long time to kill every single human. Probably well beyond our life span."

"Which is why we need to grow stronger and collect more souls to fuel our ambitions." Loki's essence flew back into the plushy."We'll start slowly to not get unnecessary attention, working in the shadows."

"Loki, are we finally going to get started?" Hazuki asked, receiving a chuckle in response.

"Yes. Now that we have a group together, I believe so." Loki addressed the four people in front of him."Today marks the birth of our group, the Divine Disasters of Valhalla. And we'll guide humanity to purification. The four of you will be the paladins that bring about the end of this miserable world."

"Chiaki Nakahara, Kamen Rider Femme." Chiaki smirked maniacally.

"Allister Albedo, Kamen Rider Ouja." Allister adopted a far smaller smile.

"Terunosuke Kuwana, Kamen Rider Gai." Terunosuke folded his arms, his brow furrowing.

"And Hazuki Kaburagi, Kamen Rider Ryuga." Loki placed a hand over his chest."Of course, like Terunosuke said, we'll need more to accomplish our task. We'll need political power, influence, and connections."

"I can help with that." Allistered offered."I can cash in a few favors from my various clients. Plus, since we'll be in Japan, I know just the man that can provide us with a base of operations without the government finding out. Of course, I doubt he'll take it well that we'll destroy his precious Japan, but he doesn't need to know that, does he?"

"Perfect! Now, let's set the stage for the event that will drive humanity to its ultimate destruction...Let's bring forth Ragnarök!"

And that marks the end of the Lost Files Chapter 1. This will be a small mini-series, probably at the end of each season going forward, if I deem it necessary.

What story with Loki in it would be complete without Ragnarök? The Divine Disaster of Valhalla has come together to accomplish this and will face off against Section Two in the next season.
