戦姫絶唱シンフォギア：戦姫と勇者

Infinite Stratos x Senki Zesshou Symphogear x Saijaku Muhai no Bahamut

Episode 1: Durandal

In hindsight, he should've expected something like this to happen. Even a young boy barely entering his teenage years like himself, Orimura Ichika, knew that he was kidnapped because of his sister. It happened in TV shows and movies and manga though admittedly, watching a kidnapping in a TV show and being kidnapped yourself in reality are two very different things.

The last thing he remembered before waking up in an abandoned building somewhere was opening his front door after someone rang the doorbell. Not a smart move but he is just a kid so it's not like he knew that a kidnapper will walk up to his front door and press his doorbell before putting him in a bag… not that he's sure there's a bag involved. He was knocked out the second after he opened the front door.

"So we got the kid with no problems. Now as planned by our client, it's time to call Orimura Chifuyu."

Ichika heard men in suits wearing dark shades and fedoras looking like mafia goons from the movies talking to each other. While his head still hurts, he did hear the men mentioning his sister. Hearing his sister's name being mentioned, Ichika's brain immediately went into overdrive as he tried to get free.

The boy struggled but the ropes that tied him to the one of the building's pillar are just too strong and tied in multiple strong knots. His struggles though did attract the attention of one of the men who kidnapped him. The mafia (because he didn't know how else he could describe them) walked up to him and grabbed him by his hair, forcing him to look at his eyes.

"Look kid, I don't want to hurt you and I'm sure you don't want to be hurt so let's make this easy on the both of us and keep quiet until your hot sister arrives, capiche?"

The mafia spoke in accented English that Ichika did not understand. He didn't sound like any American, British or East Asian trying to speak English either, although admittedly Ichika only knew how American, British, and Japanese spoke English with the last one being the worst.

Ichika knew it's not a good idea but being frustrated as he is and wanting to punch whoever this mafia goon but couldn't due to being tied, the boy did the next thing he could think of as some sort of come-back; he spat on the mafia goon's face.

The mafia wiped the spit off his cheek and sighed. Then he smacked Ichika across the face, hard. It was a testament to his stubbornness and bravery that he did not cry despite the pain… that or he's used to being hit on the head by Chifuyu that his tolerance to pain is already much higher than a normal boy.

"Oi, try not to harm the kid! We still need him!"

Another mafia goon yelled. The mafia goon who spoke to Ichika appeared to have rolled his eyes and was about to leave when the building suddenly shook.

"What was that? It couldn't be that Japanese bitch. We haven't even called her yet."

"You, go check out what it is."

One of the mafia goons pointed at one of his friends. This mafia goon wore a scarf and his suit looked even more expensive so Ichika guessed that this was the leader. The mafia goon who received the order nodded and pulled out a handgun from inside his suit. Before he could exit the room though, the building shook once again.

"I don't remember any demolition work happening ar-"

The mafia goon who spoke didn't get to finish what he was saying when the floor under him burst and something –someone- slammed onto the ceiling. The person, and something else, a briefcase and a sword, fell onto the floor, surprising the mafia group. They all pulled out their guns and point at the person that Ichika saw was a girl. The girl was about a year or two older than him. She had long blue hair with a part of it being tied into a side ponytail that reminded Ichika of a musical note and she's wearing some kind of strange armour and a blue, black and white skintight suit.

'A failed IS test flight?'

Ichika thought. But that thought was soon forgotten when he heard some inhuman voices as three… things appeared from the hole that the girl crashed through. Ichika's eyes widened in fear when he saw three black humanoid things with wings and no eyes flying through the hole.

Demons, that was the only word that came to his mind when he saw them; demonic beings that came from the deepest fiery pits of hell, and they proved to fit that description as the three humanoids saw the mafia goons and began to attack them.

The mafia goons fired their guns, but their weapons did nothing apart from bouncing off the beasts' bodies that seemed to be made of something that didn'tappear to be skin and flesh. The mafia goons screamed as the beasts bit into their necks and rip them apart with claws and teeth. Now Ichika is really scared as bits of flesh and blood flew all over the place, some even got on his face.

A man's corpse was thrown near him, an expression of terror perpetually marring his face after being killed by having half his head eaten. That is not how a human dies, Ichika thought.

He then heard a groan and saw that the girl had regained consciousness, if she was even knocked out in the first place. Ichika now noticed that the girl wassporting several minor injuries.

"Psst, oi you."

Ichika tried to get the girl's attention. The girl got up and shook her head. She saw Ichika tied to a pillar and was surprised.

"What is a civilian doing here?!"

She asked. She then heard more screams and saw another mafia goon getting killed by having half his body being blown away by the demons. The girl clicked her tongue and pull out something from her leg armour that looked like a sword hilt. To Ichika's surprise, a solid blade shot out from the hilt and it didn't look like a retractable blade at all.

"I don't know what you're doing in here but you have to run! This place is not safe!"

The girl told him. She then threw a knife that she got from… somewhere and cut the ropes tying Ichika. She immediately turned away and went to face the monsters. Ichika who is now free watched as the girl tried to save the mafia goons, not really knowing that they are actually with the Mafia.

Ichika saw her fighting against the monsters. She appeared to be able to fight them with her sword and keep up with their monstrous power and fast movements comparable to an IS but she was definitely struggling. While she could match one of them, two seemed to be the most she could handle while being on the defensive. Fighting three of them at once…

"What are you doing?! Get out of here!"

Ichika then heard the girl's voice yelling at him. The boy realized that he had barely moved from the pillar that he was tied to before. That split second of lost focus cost the girl as she was blasted by some kind of energy-based attack, though it appeared the monsters are not done with the girl as they went after her, showing that she was indeed fine when she emerged from a pile of rubble that used to be a wall with her katana brandished at the monsters.

"Run!"

The girl yelled again as she blocked a claw that wanted to impale her. Ichika was rooted to the ground. He didn't know what to do and his body was not moving due to some reason; whether it was from fear or something else, Ichika was not sure.

But he should've run like the surviving mafia goons did after the girl got the attention of those monsters because now the third of those demonic things noticed him. The monster flew at him and only his desire to survive made him move from where he stood, barely avoiding his own death and instead saw the pillar he had become acquainted with earlier be cut into pieces by the beast's claws.

Ichika rolled as he fell after jumping to a random direction. He landed just a few inches from the large briefcase that the girl dropped when she crashed into the room.

The monster that attacked him turn towards him, eager to finish the job if the feral look it had were of any indication. Ichika tried to crawl away but the beast had already crossed the distance between them in what felt like near instant.

When Ichika who was now on his back saw the beast ready to ram its claws into his body, he no longer felt fear. The boy instead felt disappointment… and anger.

'No… I can't die here. Chifuyu-nee… what will happen to Chifuyu-nee if I die here? I… if only… if only I have power!'

Ichika cried out in his mind. And then something surprising happened. A burst of energy came from behind him and blew the beast back but did absolutely nothing to him, surprising Ichika. The boy got up and looked behind him. He saw an open briefcase and… floating over the briefcase was a sword, a golden sword that radiated power. Ichika is awed by the sight, but more than anything, he felt that he is drawn to it. A word came to his mouth as he reached out to the sword.

"…Durandal."

Ichika grabbed the sword and felt power flooding into his body. Smiling to the fact that now he now has something to fight with, he turned to face the demonic thing that had attacked him and slashed at it. An enormous blast of energy was fired from the sword, destroying the monster. Ichika smiled as he felt his strength leaving his body. Now feeling very weak, Ichika passed out from releasing so much energy in one move.

Kazanari Tsubasa was wide-eyed as she saw the civilian boy somehow activated the relic that she was transporting and used its power in a single attack that blew half the building as well as the Abyss that had attacked her earlier.

She had expected to be attacked when transporting the relic from the EU and indeed, they had been attack when they set foot in Japan and was about to return to SONG HQ with Durandal. She had been separated from her senior who is fighting a number of much more powerful Abyss.

She had only just begun her training and is nowhere near her senior's level in relic output and skill. Just facing three weaker Abyss already gave her trouble while her senior could beat dozens of this type of enemies in a single slash of her armed gear. While her sword skill alone would've allowed her to beat these three Abyss, the problem was her power output. As she had just started out, she wasn't so sure about the 'singing while fighting' part of the relic that took on the form of equipment known as Symphogear.

This doubt and inexperience made her gear output suffer and thus she did not gain enough power to allow her weapon to cut through the Abyss' defences. This wasn't a good day for Kazanari Tsubasa. And now a civilian had awakened and used Durandal to defeat one of the Abyss.

After unleashing Durandal's power for the first time, the boy collapsed.

"That was impressive."

Someone commented. Then suddenly the two Abyss she was fighting was cut into pieces as her senior arrive at the scene. The senior is a teenage girl around fifteen years of age. Like Tsubasa, she wears a Symphogear armor like Tsubasa with her color being white, black and orange and she wields an enormous white and golden lance. She has long fluffy red hair reminiscent of a feather and is currently the oldest active relic user on the field.

"Kanade-san."

Amou Kanade grinned as she went to pick up the boy and Durandal.

To think that the next person to be able to use a relic is a boy, this is an interesting development. While relics are not strictly limited to females like those Infinite Stratos are, so far Kanade had only seen females using relics so this is quite a surprise. Plus she doesn't mind having a male as her junior.

"Let's head back. The commander would love to hear about this."

So here is my newest crossover which I will also credit to RedWolff from Spacebattles in its creation. I have always wanted to write a Symphogear crossover since I love a series with good songs and since my Macross x IS idea won't be coming true anytime soon due to... stuff. So here we have Ichika during that kidnapping incident which I changed somewhat which will definitely change things in IS canon eventually. Ichika got himself a relic to use and it is Durandal from Symphogear S1. I'm not sure if there is a rule in Symphogear that says only girls can use relic but in here, it is not limited to girls but through compatibility and potential. Also, this is not just a crossover between IS and Symphogear since some of you probably noticed that instead of Noise, there is Abyss like the one in Saijaku Muhai no Bahamut. This is a triple crossover between Infinite Stratos, Senki Zesshou Symphogear, and Saijaku Muhai no Bahamut.

Also, I feel some sort of fate or karma that it is Durandal that Ichika use since my favorite character and permanent waifu is Xenovia Quarta from DxD who uses Durandal.

I should mention this that pairings are already decided and it will be single pairing with little chance of developing a harem.
