Hey everybody Aquas1998 here and this is the first crossover of Senran Kagura/Warframe as well as my first fan fiction. I would like to thank FloppingPenguin for convincing me to write this story as well as revising and editing it. It comes to my surprise that no one has ever done it and I thought I could make this thought a reality. You'll probably find some punctuation and word errors while you read through the story and that's why I'll look at your reviews to see the mistakes I made in order to improve the story. Anyways, I hope you guys enjoy the story and I'll write the next chapter when I have the time of not being a lazy ass.

Chapter 1: New Allies?

Hanzo Academy training grounds. Noon.

Hanzo National Academy. A prestigious high school that stands in the Asakusa District of Taito, Tokyo. But, from what the public did not know, it's also where good Shinobi train to fight against those aligned to the darkness, the evil Shinobi otherwise known as Akunin and the their good counterpart, Zennin. In order for the Zennin's school to be kept in secret from the common eye, they masked it with another name, Mammoth CP Academy, as their front as a normal institution. For this reason, they are able to train in secret without any compromise.

In the woods of the school, a girl named Katsuragi, the perverted third-year tomboy, has long blonde hair with a thin blue ribbon across the top, knotted with two bows on each side of her head, bluish-green eyes and wears a Hanzo Academy uniform but in a rather revealing manner. The white shirt is unbuttoned as well as no bra, revealing her cleavage and her torso. Her lower part of her body is a blue plaid skirt and long white socks along with her signature weapon; her metal greaves colored in black and gold added with small blue tassels on each side of her boots, serving as her weapon of choice. This to her, is her Shinobi attire.

Ten feet in front of her, Ikaruga, Hanzo's third-year class representative, is a refined girl with long, straight black hair that passed her lower thighs and flat cut bangs resting on her forehead with blue eyes. Both knew each other during their first year in Hanzo, and despite their differences, they forged a bond with each other. For her Shinobi attire, she wears a white gold-trimmed jacket with six buttons and a few golden tassels strewn across as well as an armband pinned to her upper left arm. She has a short gold-trimmed white skirt and boots of similar colors to her jacket, accentuated by black tights underneath. In her hands, she holds her sword named Hien, a Nodachi that is the heirloom of her family passed down to her father.

"Prepare yourself, Katsuragi-san," she advises to the blonde tomboy, holding her blade in her combat stance, waiting for her to make the first attack.

Katsuragi chuckles with a smile as she is ready for another sparring session. "Let's go then."

Nearby them, two girls are watching them as sparks from their weapons collide from each other. One named Hibari, the upbeat first-year, has pink hair accessorized with three black ribbons that tie it into two pigtails with distinctive eyes colored in pink with the pupils shaped like a cross. The other, Yagyu, the stoic prodigy, has long white hair tied into twintails with a small shuriken holding it up with an eye-patch covering her right eye of red. Both of them are wearing the Hanzo student uniform consisted of a white shirt, a blue tie matching the skirt and white socks inside their brown shoes in contrast of how Katsuragi puts it on.

"Hibari doesn't think she can be better than Ikaruga-senpai and Katsu-senpai.", Hibari expresses with doubt, lacking of self-confidence in her that she believes to be inferior to them, even by a first-year standard.

"Do not worry Hibari-chan.", Yagyu reassures her, despite her monotonous cadence. "I know you can be the best as us.", this results in Hibari smiling that she can be as good as her senpais, giving her a bit of boost to her confidence in her ability as a shinobi

Katsuragi performs a flying kick, but Ikaruga slides under said kick. She lands on the ground sliding, leaving a trail from her grieves before coming to a halt, turning around to see the representative about to slash her with her sword horizontally. She jumped back and dodge every flurries of swing from her until she gets a better angle to counter-attack. Ikaruga swings it slantingly to her right, leaving her left side open for the kick. As the kick is about to connect, Ikaruga has managed to block it, only to slide back a good five feet with her sleeves torn from the impact as well as a little exposure of her well endowed chest.

Katsuragi chuckled, all the while doing a little limbering before any form of offense, or defense, "Nice save Ikaruga. But on the bright-side for me, I get a little beautiful view of your knockers there.", she tauntingly expresses her perversion, with the reason is being herself.

Ikaruga is unfazed at the fact some of her cloth of her jacket has shredded, focusing on the spar to her is serious. "Don't let the little things distract you Katsuragi-san."

"Ahh whatever. Let's keep it coming!", Katsuragi simply dismisses her words before proceeding to charge at her to attack.

"Secret Ninja Art: Flying Swallow Phoenix Flash Style One!" Ikaruga slashes rapidly with her sword as Katsuragi is close to hit her hit range, cutting off pieces of her clothes as tracing lines shown visibly in the air where she attacked. She sheathes her sword as the last bits of damage of her traced slices takes effect, causing most of Katsuragi's clothes gone leaving her only a white and blue bikini as she her face meets the ground. Ikaruga believes that she wins the match against her. But she thought wrong, as Katsuragi lifted herself up and is now on her feet, bent on one upping her.

"I still have more energy to use on you Ikaruga. Secret Ninja Art: Cross Panzer!" Katsuragi throws her arms to her sides and her head back. Her greaves begin emitting a green energy that spins around them like a whirlwind, suspending her slightly in the air. She charges towards the senior representative with great speed and launches into a fierce barrage of kicks, shredding Ikaruga's clothes with ease, ending with her jumping high into the air and slamming her foot down on her. But that last attack is a miss as Ikaruga dodged that devastating finisher. Ikaruga is left with tattered remains of her jacket and her tights, revealing her black bikini.

"Well put to your attack, but this is where it ends.", Ikaruga runs at her at full speed with Katsuragi mirroring her actions. As they are about to collide into a explosive finish, suddenly, a smoke bomb appears in both their sights in front of them. They unintentionally enter as their speed is making difficulties to stop, tripping them as they cough from the smoke. They got out of it while they're rolling, now the two being on the opposite side of where they were about to collide.

After the smoke has dissipated, a man, about 40 years old, with gray wavy hair and auburn colored eyes dressed in a black suit in the middle of the training grounds is the girls teacher, Kiriya. Recognized as one of the best shinobis of Hanzo, yet little is known of his past, it's stated that he is teacher that should be taught under his knowledge.

"Girls, you have been given an assignment.", he simply tells them with strict briefness in his tone of voice, emphasizing his experience of both shinobi and teacher.

The girls huddle up with each other as well as the first years, listening to their sensei. But before that, the third-years have to shift back to their uniforms since their current clothes is not suitable for any briefing.

"Alright! What's the assignment? Sabotage? Escort? Assassination?", Katsuragi's itching for what she is assign to do, since in turn, none of them have actually experienced a real mission, or real combat for the matter.

"What is it Kiriya-sensei?", Ikaruga asks, whom she is also brief just as Kiriya.

"Assignment?", Hibari chimes in the question at hand.

"Please do tell of it sensei.", Yagyu, waiting for what he has to instruct them to do.

"I want you girls to go into the woods Northeast from the school. We have heard complaints from the normal students about a mysterious figure being spotted going in and out of the woods. So far, the scouts were sent in and returned that there is a cave, that not even we knew about. The figure is not one of ours however. So, I need you girls to go and there and look for whoever it is."

"Mysterious?", the pinkette does not understand, as she slowly tilts her head. Her thoughts form into questions of why would someone enter a cave for, let alone how did they managed to bypass shinobi grounds.

"I do not know of it myself as well. But, it is vital to investigate before it goes cold. We cannot risk potential threats should this be left on its own."

"Yes Sensei.", all the girls said in unison, before they move out into the woods, to find the cave and see what holds that caught the Hanzo's interests.


10 minutes later in the woods Northeast.

They venture deep into said woods. But a certain blonde tomboy is already bored of this assignment from just a simple walk. "When are we getting to the caves?", she asks in a tired tone, hunched over as though she'll collapse at anytime.

"It is not far Katsuragi-san." Ikaruga replies, leading in front of the pack as their unofficial leader.

Katsuragi sighs, but she thought of something to pass the time. She lines up in a row and gets closer to Ikaruga from behind, and wrap her left arm around her neck and gropes her breasts.

"E-eh!", Ikaruga blushes as the blondes left hand harassing her chest. "Stop this at once, Katsuragi-san!" She did not do as she demands, rather that she continually fondle them.

"Come on, we need a little excitement on this boring walk." Katsuragi continues to harass the representative, until her eyes shift in front of her to see a massive cave in front of the them all, her hand letting go as she sees something that's not possible. They stopped to observe the cave that was covered by trees higher than itself. All the four looked at in amazement.

"This is impressive.", the representative approaches the cave in awe, surprised that this was never found at all in their territory.

"Let's go in then! This has to be it!", Katsuragi is tempting to go in to see what's inside.

"Wait.", Ikaruga stops her before she can do anything else, explaining to her, "Before we can, we must take a look outside first for traces of that 'figure' Kiriya-sensei has mentioned."

The blonde groans in boredom of her refined friend's carefulness. "Come ooon. Whoever or whatever it is, it's long gone. No way there's anything to tell us 'it' is here."

"We don't know that unless we are sure 'it' is, Katsuragi-san.", She persists on her suggestion to look around. While they're bickering on what to do to investigate, Hibari went into the cave out of curiosity. This causes Yagyu to look for her. She founds her already inside the cave before she is no longer sight. "Hibari!", the first year shouts her name in fear of losing her, before jetting in to get her back to the group. The third-years hear her shout, causing the blonde to grin and replies with, "Guess that settles it. Come on Ikaruga!" Both of them follow the two, a sigh from the representative in annoyance as they chase them from behind.

The pinkette is in awe, yet intimidated of how the insides of the cave looks. The sound of it is hollow, the shape is blunt and edgy with stalactites hanging as if they'll fall on her at any moment. But upon furthering into this lifeless solid vore, she finds something that made her forget the fear built up inside, with her jaws hanging at what she almost could not comprehend

Yagyu finally caught with her. "Hibari. You cannot just out of instinct to go and-...", her words were cut off at the sight in front of her and does the same thing Hibari did, mouths agape of something unbelievable.

The third-years, Ikaruga and Katsuragi, has finally caught up with the two. "There you are you two." Ikaruga infuriated by them for separating themselves from the group. But all that was gone when the blonde and herself sees what they are seeing. In front of them, are five strange pod like machines, standing, glowing blue from the glass chambers in front, holding five people with their arms crossed with their palm of their hands touching their shoulders. Four most likely males and the other a female, wearing bodysuits of some sort. Next to them each outside of their cryogenics chambers, are futuristic lockers. Both the pods and lockers have red lights on top of their mantles, indicating they're locked.

"No, way.", Katsuragi doesn't believe in what she is seeing, thinking that this is a mind game. "Is this for real? This is something from a sci-fi flick."

"I... I don't know how to respond", Ikaruga is loss for words at such a sight not possible, "This, was the reason for the figure to be here?"

"This is so cool!", Hibari is amazed on how the pods look, but Yagyu follows both third-years reactions. However, the mission has not changed, as now the girls are looking for what else can there be in this desolate underground. There is only one thing they did not notice, a computer connected to all the pods via long and thick cords, acting as their life support. Ikaruga takes a look at the computer to see if there is anything she can find out who these sleeping people are, though the design is significantly advanced, yet works the same as any other computer. Katsuragi is looking at the pods, mores specifically the people inside of it, interested as they look young, likely to be around their age. Hibari does the same thing with the blonde albeit wondering who are they, with Yagyu tagging along, observing them with caution. "Yagyu-chan~. Hibari wants to know why they're sleeping in these cold beds.", she places a hand on one of them, looking into their slumbering eyes, feeling as though she wants to save them.

Yagyu wants to know as well, replying to her, "I do not know Hibari. And yet, I speculate that these people must have been kidnapped and forced into something sinister. What had happened is what I want to find out." The pinkette nods at her wonder, now pulling her hand away from the pod. She then continues to the middle of the row, out of wonder who the person looks like. When she comes upon it, it suddenly starts to give out discharges, malfunctioning with smoke coming out of the sides on the top with electricity surging around said pod. The electrical current begins to make its way from the cords to the computer where the representative is, surprised as she gets away with her arms covering her face.

"Ikaruga!", Katsuragi shouts at her with stagger in her voice, looking to her direction to where she is with herself having one hand covering her eye to protect herself from the blinding electrical surge, "What did you do?!"

"I did not do anything! I was looking at the computer screen without as even touching it!" She exclaims, just as she narrowly avoids the stray electrical currents heading for her, only to hit the insulated rocky walls, yet left a blackened Lichtenberg.

The eye-patched girl is covering Hibari from the electric overload with her oilpaper umbrella she always carries with her. "Yagyu-chan! What's happening?!", the pinkeye is covering her head as she crouches down.

"It's some sort of haywire!", she explains, her umbrella insulating the electricity, gritting her teeth in hopes that it will hold out the lethal voltage from reaching to her and Hibari. When the malfunction has ceased, the computer shuts down but before saying, "Systems no longer in working condition. Emergency unlocking engaged." The pods open, just as the five people fall out of it and hit the ground, still unconscious from their frozen slumber. The girls without hesitation, rush to their shivering, yet comatose state, seeing them curling themselves up into a fetal position to preserve heat, their breathings shaky and irregular, trying to figure out what to do in this unexpected turn of events.

"Wha-what are going to do Ikaruga?! They just suddenly have one bad short-circuit and now they're about to die from their sleep!", Katsuragi is rushing her words as she never knows what to do in a rescue operation, or a sudden rescue.

Ikaruga has no choice, but to say this as her best solution in order to save them, "We have to get help. You three stay here and try to give them warmth as much as possible, while I will return to the school and tell them, this has turned to a rescue mission."

"Then you must move quick!", Yagyu tells her as she pulls out her shinobi scroll, then shouts out, "Shinobi Tenshin!", she raises it as streams of light coming out of it begins to cover her, her school uniform disappearing in the process. As the light covers her developed parts, she changes into her Shinobi form, which is a brown jacket over a long white long sleeved shirt, a red plaid skirt, calf-high black socks and brown dress shoes. She removes her jacket, revealing her pink frilled bikini top, to cover the frozen girl who's shivering the most. Her hands felt the absolute chills when she covers her, muttering, "How can they sleep like this?"

Katsuragi moves the frozen people to each other in order to get as much heat as possible with Hibari's support. "Is there anything else we can cover them with?", Katsuragi asks the first-years hurriedly, trying to look around for something warm.

"Hibari's jacket!" The pinkette realizes that there's another jacket. Unbuttoning the top of her uniform, it reveals a little bit of her cleavage, which the eye patched girl has a nosebleed upon sight, yet retains a calm demeanor. The pinkette's hand is searching through her immense breasts between to reveal a scroll of her own. "Shinobi Tenshin!", she raises her scroll as streams of light coming out of it begins to cover her as well, just like Yagyu's transformation. As the light covers her developed parts, it turns into her Shinobi attire reminiscent of a student in gym class. She has a light pink track jacket with the Hanzou emblem on the left chest area, dark blue biker shorts, black and white socks, and red and white sneakers. She unzips her jacket as she covers one of the boys, with her top being the same pink frill bikini top the same as Yagyu's, adding that it compliments her also large breasts.

"Hang on you guys, help is on the way.", Katsuragi said as she adjust the shivering people to be more comfortable. The muttering of their shaken voices are heard, yet too difficult to make out, but she understands that they feel as though they might die of hypothermia. "You'll be alright you guys. We got you."
