A/N: People are interested I suppose. Then by your continued interest, I shall keep going. Like I said in the prologue, Robin's tomes will be explained in this chapter. I will also like to note that they have brought quite the amount of Second Seals and Master Seals. As a result, there may be changes to the characters. Every time there is a change to a character, I will note the respective changes at the end of the story in that A/N. Now then, let us begin!

Disclaimer: I do not own Fire Emblem or Highschool DxD.

Chapter 1: Devils and Fallen and Angels, Oh My!

The group of four flying people stared down at the eight Ylisseans. No one moved a muscle, as if time had been stopped in the immediate area. "Now that I think about it…", Robin thought to himself. He did a quick scan of the surrounding area. An empty park with a giant fountain behind them. "...No reaction? Not even a simple yell or scream?", asked the leader of winged people.

"Well to be fair, where we come from, supernatural creatures aren't anything new to us", Noire said nervously.

"Bah, that's boring. I was hoping for some sort of reaction", said the leader.

"Well, if you don't mind me asking, what are your names? I'm Robin."

"You may call me Panne."

"Uh, Yarne…"

"I'm Morgan!"

"Severa…"

"I am Inigo."

"My name is Noire…"

"Behold, my name is Owain!"

"Well, I suppose you'd rather know the names of who's going to be killing you. You may call me Raynare", said the leader.

"My name is Dohnaseek", said the male.

"Ugh, Mittelt", said the little girl.

"And I am Kalawarner", said the tallest woman.

"Raynare, Mittelt, Dohnaseek, and Kalawarner. Very well, since we are new here, I hope you don't mind me asking exactly what you are? As you could probably tell, we're not from around here", said Robin.

"You mean you've never heard of Fallen Angels? Surely you must have if you've dealt with the supernatural?", asked Kalawarner.

"Nope, I think I would remember seeing black angels flying in the sky back home", said Inigo.

"You guys say you aren't from around here, where exactly are you from?", said Dohnaseek.

"We are from the halidom of Ylisse!", said Morgan.

"Ylisse? I've never heard of a place like that in Japan, or anywhere else in the world for that matter…", said Mittelt.

"Japan? I don't remember any outrealms with the name 'Japan'...", said Severa.

"You mean we've jumped worlds and not just to another outrealm?!", said Yarne.

"Worlds… I think I know what's happened here. You all have been brought here through the Dimensional Gap", said Dohnaseek.

"Dimensional Gap?", asked Panne.

"A space that is home to the strongest beings in existence and a portal to a limitless amount of worlds. That is my only guess as to how you all arrived here", explained Dohnaseek.

"So we have achieved the impossibility of travelling worlds? Truly we have accomplished a magnificent feat!", said Owain.

"Not on purpose you idiot!", yelled Severa.

"So, is there a way for us to get back?", asked a hopeful Noire.

"If you wanna take a shot at avoiding Great Red and Ophis to go home, be our guests. You wouldn't last even a millisecond fighting them", said Raynare. "Of course, you'll be dying here, so you'll never get that chance."

"Ah right, you want to kill us. May I ask why?", asked Robin.

"Why should I explain myself to humans?", snarled Raynare.

"Actually, we're not humans", Yarne said pointing to himself and Panne.

"Now that I look at you closer, you two look more like Youkai. What are you two doing with this humans?", Dohnaseek.

"Why should we explain ourselves to people who want us dead?", countered Panne.

"Touche. Very well then, it seems the time for talk is over", said Dohnaseek said as the four fallen charged.

"Owain, you're with Morgan in taking out Kalawarner. Panne, you and I are going for Raynare. Severa, you and Inigo take out Mittelt. Noire and Yarne, you two go for Dohnaseek. Move!", Robin ordered as the group split into their pairs and charged their respective targets.

"So you aren't all talk after all. While I prefer you screaming and begging me not to kill you, I do enjoy a good fight from time to time", said Raynare.

"I've died already, it isn't pleasant. I'd prefer to stay alive this time around", said Robin as he took a Levin Sword. He began reaching for his tomes, but he couldn't feel anything. "...What?"

"Is something wrong Robin?", asked Panne.

"I can't find my tomes, but they were right here!", Robin said checking all his pockets.

"Tomes? As in magic tomes? You're a magician?", said Raynare.

"I wouldn't exactly call myself a mage, but yes I do know magic", Robin answered, continuing to search for his tomes. "Don't tell me I lost them when we were transported…"

"We can worry about it later, for now, we fight and survive", said Panne.

"I suppose you're right", said Robin as he pointed the Levin Sword at Raynare. Nothing happened.

"Was that supposed to do som-" Raynare was cut off as a lightning bolt struck her in the chest. She flew back on the ground with a thud since she was not prepared for it.

"Yes, it was", said a smirking Robin.

"Be careful you three! These people have tricks up their sleeves!", Raynare yelled to the other Fallen. "I'm going to enjoy wiping that smug look off your face."

"You can try. Only one person has ever succeeded in doing it and he's dead now", said Robin.

Raynare charged Robin, light spear in hand. Panne tackled Robin out of the way due to Robin's slow speed. "This is gonna be a long battle! Don't do anything reckless!", Robin shouted as he and Panne began fighting Raynare.

Noire and Yarne were fighting Dohnaseek in another area of the park. "So a Youkai and a magician make up the leaders of your little team. What are you two, the cavalry?", asked Dohnaseek as he threw a light spear.

"Nope, that would be Morgan", said Yarne as he dodged a light spear easily. "Though I have to admit, I don't know what a Youkai is…"

"Worry about it later Yarne, we have a fight to worry about!", said Noire as she fired an arrow at Dohnaseek.

Dohnaseek was decently fast as he made a dodge, so it absolutely surprised him when the arrow found its way into his leg. "What?! There's no way a normal human could have hit me like that!", said Dohnaseek.

"Guess that means I'm not normal then huh?", said a confident Noire.

"Impossible! Only a Hunter could land a shot like that!", said Dohnaseek. "And I know for a fact you're no Hunter."

"Hunter? What are you talking about?", said Yarne.

"Bah, no more talk", said Dohnaseek as he charged at Noire, easily seeing that she's the threat. Yarne pushed her out of the way.

"Thanks…", said Yarne.

"No problem, we can't go dying here now after all we've been through!", said a smiling Yarne.

Noire and Yarne weren't always this different. Through a lot of battles and talking, they've changed each other in a great number of ways. Yarne has found the confidence he needs to no longer be afraid while Noire has found the confidence she needs to speak up more. A thrown spear nicking Yarne's shoulder was enough to set Noire off.

"BLOOD AND THUNDER! YOU DARE HARM MY FRIEND IN MY PRESENCE?! TO THE ABYSS WITH YOU!", shouted Noire as Lethality activated.

The arrow found its way into Dohnaseek's shoulder and he screamed in pain. This shocked Yarne, since Lethality had always killed anything it touched. So for Dohnaseek to live through it, it must mean that their skills have been changed in some way by this world that they're in. "Guys! Our skills and weapons may have changed! Try and find anything new!", shouted Yarne as he and Noire continued fighting Dohnaseek.

"Our skills and weapons may have changed? What does that mean?", asked Inigo.

"I think he means that our skills and weapons may not work the same way as they did back in Ylisse", Severa said as she blocked a light spear thrown from Mittelt.

"Oh? That could be problematic…", Inigo said as he swung at Mittelt and hit her torso.

"Agh! Why won't you just sit still and die already!?", said an enraged Mittelt.

"Gee I don't know, maybe because we don't want to die?", mocked Severa.

Mittelt charged at Severa once more, this time with two light spears in hand. Severa blocked the first one, but the second one was going to hit her in the chest. Inigo took the hit with his own shoulder. "Inigo! You idiot, you could've died doing that!", yelled Severa.

"For you, it wouldn't be a bad thing", said Inigo as he swung his Silver Axe into Mittelt. The strike proved to be effective as Mittelt was knocked back super far. What surprised Inigo and Severa was that when the strike connected, Inigo's shoulder wound started healing on its own.

"What the? You didn't activate Sol though…", said Severa.

"So this is what he meant by our skills. In that case, Severa, try using Astra", said Inigo.

Severa ruched over to Mittelt as she was getting up. "I've had enough!", she said as she unleashed a whirlwind of sword strikes on Mittelt, knocking her back even further.

"I see now! Good call Inigo", Severa said.

"No problem, now let's wrap this up!", said Inigo.

Morgan and Owain were facing Kalawarner. Kalawarner started aiming for Morgan, seeing as how she was telling Owain exactly where and when Owain should dodge and attack. Owain rushed in front of her and took a defensive stance. Kalawarner thought nothing of it and hit Owain, but was shocked when Owain not only nulled the attack, but completely countered her too.

"I see! So my Counter is actually a counterattack now! Hey Morgan, try using Rally!", said Owain.

"Sure!", Morgan said as she activated Rally Spectrum. For a brief moment, Owain gained a rainbow hue before returning back to his normal self. "So the Rally skills are still buffs, but they're much stronger and don't go as far."

"Agreed, I feel way more stronger here than I did on Ylisse. Stand back as deliver justice to this Fallen Fiend!", Owain said as he charged Kalawarner.

"Nuisance…", Kalawarner said as she threw a light spear at him. Her light spear was driven off course by Morgan throwing a Spear at it, clearing the way for Owain.

"Abysmal Body Blow!", Owain shouted as he unleashed Astra on Kalawarner.

Kalawarner was blown back and hit Mittelt as they both collapsed in a heap, unable to continue fighting for the moment. "Nice!, Let's go hope the others!", said Morgan.

"Lead the way, Morgan!", Owain said as he followed her to help Noire and Yarne as Inigo and Severa ran to help Robin and Panne.

Robin and Panne were in quite a dangerous situation. Panne couldn't find her beaststone and Robin could only attack with his Levin Sword, so when Inigo and Severa blocked a thrown light spear for Panne, Robin was grateful. "Thank you both. It becomes kind of tedious when she expects lightning bolts from everywhere now", said Robin.

"No problem, Yarne has informed us that our skills and weapon don't work the same way as they did in Ylisse. So my best guess would be to try something new", said Inigo.

"Something new…", said Robin. He had a ludicrous idea, one that could only be tested. He raised his hand towards Raynare and shouted a simple spell. "Elwind!"

Raynare was caught by a blast of wind magic that sent her tumbling into the ground from her airborne position. "What?! I thought you only knew Lightning magic?!", said Raynare.

"When did I ever say that?", asked Robin.

"You've been using nothing but lightning spells!"

"...Oh yeah, but this is a lightning sword, and I explicitly remember saying 'Tomes'. Plural", said Robin.

"How troublesome…", Raynare said before rushing over Morgan, attempting to blind side her.

"Morgan! Behind you!", Severa shouted.

Morgan turned around to see Raynare charging at her, but she was in no position to dodge or counter. Something big blocked her view as Raynare's attack was blocked. "What?!", she said only to look up and realize she made a mistake challenging these people.

In front of her was a demonic looking rabbit about three times the size of everyone in the park. "You have made a big mistake, Raynare", the rabbit said in a distorted voice as Raynare was swatted aside like a fly.

"What is that?!", shouted Dohnaseek before a second rabbit swatted him in the same direction as Raynare.

One was wearing blue armor while the other was wearing purple armor. "Oh? You mean you don't recognize us?", asked the second rabbit.

All four Fallen get up to realize that two of the eight Ylisseans are missing. "You two are giant demonic rabbits?!", said a scared Mittelt.

"Nonsense, we are Taguel. A race of shapeshifters if you will and we are the last of our kind", said Panne.

All four Fallen get up and prepare to attack again, but another spell of some sort causes them to back away. Everyone looked to see a group of four people with a different set of wings than the Fallen. Like the Fallen, the group consisted of three women and one man. "I hope you didn't come here to cause trouble in my domain, Fallen", said the red head.

"Bah, Devils. There's no way we can fight both them and these eight. We're leaving!", ordered Raynare as the four Fallen took off, leaving the Ylisseans with the Devils.

"Well, that's one problem taken care of…", said Robin as he turned to the new group of four. "So I take it you all are Devils?"

"You talk as if you've never heard of us", said the red head.

"We're new here, that's all we're gonna say", said Severa.

The group of eight, while not exactly aiming their weapons at the Devils, still had them out in case they weren't friendly. "So five humans, a Magician, and two Youkai, quite the group you all travel in", said the red head.

"We're Taguel, not Youkai!", said Yarne.

"Very well, so what are you doing here in my domain? Depending on your answer, I may let you go", said the red head.

The Ylisseans took a good look at the four Devils in front of them. The red head, obviously the leader, had blue eyes and was what Inigo would say, "A total cutie". The black haired one must have been her second in command since she stood right next to her. She had purple eyes and a very scary look on her face, one that reminded Robin of Tharja if his shuddering was anything to go by. On top of that, when she saw Robin shudder at her sight, her face seemed to take a more sadistic look, ultimately scaring all the males in the group. The small white haired female looked like she couldn't have been anymore than ten, but the impassive look in her golden eyes seemed to speak volumes that she was a capable fighter herself, though once she looked at Inigo, she seemed to take a particular look, like she disapproved of him. Finally came the blond haired male of the group. He carried a sword in his hand and his bluish gray eyes showed that his was quite confident in using it. He also had a mole underneath the left eye. Upon looking at Owain, he saw started smirking, like he was itching to fight him.

"Forgive me for being a skeptic, but we were just attacked and a little on edge at the moment. What reason do we have to trust anything that you're saying?", asked Robin.

"If you're implying that we're allies of the Fallen, we are not. I believe the saying goes 'The enemy of my enemy is my friend'", said the red head.

"I'm currently having a hard time believing that", Robin said as he looked at Kiba.

"The red head followed his gaze and saw the sword. "Kiba, stand down."

The blond, Kiba, put his sword away. "I still don't know about these guys Buchou, they're more than a little out of place here."

The Ylisseans put away their weapons, but were still on guard about them. Yarne and Panne changed back into human forms once they realized that the Devils truly had no harmful intentions. "Very well, if you must know, we've come a long way from home investigating something that I believe came from here. I suppose you wouldn't have any idea of what this is?", Robin said showing the cut off black wing to the Devils.

All four of them tensed. "Why do you have a cut off Devil wing?", asked the red head.

"Well, I found it when I was doing one of my patrols back home. It was in front of our Outrealm Gate", answered Yarne.

"And you came here to find out whether you have friends or foes here, correct?", assumed the red head.

"More or less, we also came with the intention of helping out if possible, but it seems we cannot make our way back home at the moment", said Robin.

"I see. You haven't done anything particularly harmful and you acted in self-defense against the Fallen. Very well. Stand down guys, they aren't our enemies", ordered the red head.

Naturally, the tension in the park vanished when everyone calmed down. "Then if nothing else, allow me to introduce myself. I am Robin", he introduced himself.

"My name is Panne."

"Severa…"

"Behold, I am Owain!"

You can call me Inigo."

"I'm Noire…"

"Nice to meet you, I'm Morgan!"

"I'm Yarne."

The red head bowed as she introduced herself. "I am Rias Gremory. With me is my queen Akeno Himejima, my knight Yuuto Kiba, and my rook Koneko Toujou. As you may have guessed, we are Devils."

The three nodded respectively as she introduced them. "I hope we get along well", Akeno said a bit suggestively.

Robin stepped a bit closer to his wife while Yarne hid behind Noire. Owain just look a little uncomfortable, but Inigo seemed to like the way Akeno talked. "Well I suppose a cup of tea is the best way to get to know each other I imagine", said Inigo.

"You idiot! Now is not the time to be womanizing!", Severa said as she bopped him on the head.

"Actually, I think a cup of tea is a great idea. I would like you all to join us", said Rias, signaling them to follow her.

"...I don't know what to be more surprised at: The fact the Inigo's suggestion actually worked or the fact that we travelled worlds…", said Morgan.

"Well, your call Robin", said Panne.

"We should hear what they have to say. They are offering after all", said Robin as he started following the Devils.

"I mean, there's no reason why we shouldn't, so I guess it's okay", said Noire as she followed Robin and Panne.

"Devils and Fallen live in this mysterious world. What else awaits us on our inquisitive journey? I'm so excited!", said Owain as he followed suit.

"I suppose things couldn't be more complicated than this right?", said Severa as she was the last one to follow the group.

A/N: Severa, you have no clue what world you all got sucked into. There's the first chapter done! Chapter two will come after chapter 11 of Another Universe. I will be alternating the stories in which I update now. So if you want to know when either story will be updating, keep up with them both. I've been getting some pretty good opinions for Another Universe, so I say go check it out! Peace!
