An Unexpected Summoning - Part 2

The sun just began to rise over the roofs of the Shinjuku District, which had been rebuilt and maintained by the Japanese Imperial Demon Army, or JIDA for short, as the first rays of sunlight entered Yuichiro Hyakuya's room. That however was not enough to wake the sleeping black haired teen up. He sometimes got berated for being sleeping too long, but he mostly didn't care. What he cared for and what his superiors wanted from him to care for were mostly two different things, leading to a some conflict in any case. Basically, Yuichiro was not suited for being a soldier, because he did waht he wanted to anyway.

"KIYAAAAHHHH!?"

"WHAA!"

What made him jump up and fall out his bed was the scream of his female squad member (and technically superior) Shinoa Hiragi, which echoed through the entire dorms. Rubbing his chin in pain, Yuichiro opened his eyes as he pushed himself off the ground, his legs still entangled with the sheets of his bed. His head throbbed in numbing pain as he tried to make out anyting through his still blurry eyes.

"Ugh! What the hell is wrong with Shinoa today?" Yu grumbled as he turned to his nightstand to find the clock reading 6 in the morning, which was usually still too early for him to stand up. However, his mind got distracted as he noticed movement in his bed, when suddenly a certain girl about his age with long black hair rose up from her sleep. Her hair mostly flowed down perfectly from her shoulders to her waist, but a few bangs and strands were out of place, springing out the mass like twigs from a bird's nest. She scowled as her red eyes looked around.

"Is it truly impossible for you People to respect an emperor's sleep? What a pain. I just want to sleep a bit longer." The girl said as she let herself fall back on the sheets, not even bothering to pull them over her body again, which was only covered by one of Shinoa's black nightgowns. Why did Shinoa have such an article that was on the borderline to being a bit erotic was something Yuichiro didn't knoew, didn't care and was not affected at all by the state of that Girl sleeping in his bed. "Yuu... find out what's the matter with her." She said weakly as made a last gesture with her hand in Yuichiro's direction as if dismissing a servant, which annoyed the teen a lot.

However, even though he wasn't the brithest candle in the candelier he knew to not mess with this girl. For this unassuming person was none other than the famous historical figure Oda Nobunaga or Archer as she called herself.

At the beginning of the master/servant relationship, Yu and Nobu (a nickname given to her by Shinoa) didn't get along at all, always arguing with one another over the smallest things. However with the time, the two got along a bit better, though it was not much as they only agreed on one thing. Nobu proved to be quite a handful with her nonchalantly personality and her holier than though attitude. She referred even to other people in the JIDA as her subordinates, showing no respect to the Hiragis or anyone. Even Yu's superior Guren Ichinose tried to make her behave a bit better and ended up having almost his guts spilled out from a large hole in his torso and his head impaled on a sword just to show the other people how much Nobu didn't care about them at all.

Yu of course had been mad at her for that, but Nobu simply waved his arguments off as if he was just air to her. He was tempted to use a command seal, the strange symbols on the back of his left hand. However, to anger Nobunaga was like poking a lion, who had not eaten in weeks, with a really short stick. She even threatened him to get her point across. Quite weird when she had told him that his 'prana' was keeping her in this world to fight by his side, though it looked more like It was the other way around and Yu would slowly become Nobu's footsoldier. Not just because of her not respecting Yu as her master, but her combat style.

A few times she and the Shinoa Squad had been hunting vampires already and Nobu was just even more straightforward than Yu. The black haired boy was known for ignoring orders and charging in blindly, but Nobu just put that on a whole different level as her attacks were way more destructive and she never got wounded in battle with the ordinary vampires, only adding fuel to the fire. After a battle with the demon emperor the scenery had changed most of the times from a post-apocalyptic city to a battlefield of destruction as colateral damage was really nothing to the demon archer.

And right now that demon emperor slept in again, snoring slightly in his bed.

Sighing, Yu changed into his JIDA uniform as he left the room with his cursed gear Asuramaru on his hip. The sentient demon inside the sword didn't like the archer really. Not for her personality, which he had already gotten used to thanks to be Yuichiro's weapon, but rather the fact that she could see him and threatened him as well. Asuramaru didn't knew whether she was bluffing or not, but all his senses screamed at him in panic as he could feel her power. What destruction she brought upon by simply hunting vampires was already terrifying for the JIDA, but that was simply the tip of the iceberg. Asuramaru could feel that and that was something that made him actually not voice out his opinion to Yu. The last time he did, she appeared in their shared mindscape, that desolated endless plain with only white gravels covering the ground, and actually beat him into submission. Sure it was basically impossible for a human and Yu didn't raise his hand against Asuramaru ever before, but Oda Nobunaga had nothing of a disobedient demon that dared to talk ill about her.

So she kicked him in the crotch really hard. Even Yu recoiled at the high pitched scream and the sickening cracking sound from his cursed gear's pelvis. Since that day Asuramaru was basically backing off with his control over Yu's Body whenever the Archer class servant was present.

Other than the death threat of Nobunaga, the Yu and her got along very well. After all they shared a common goal.

The Liberation of Japan from the vampires. When Yu and the others of the JIDA had explained this to her, Nobu almost began to assemble a force to lead an attack out into the destroyed city. To say she was ambitious was putting things lightly. She as the late emperor of Japan simply wished for one thing and that was conquest. It was basically contagious as even Yu in his density felt like they could do it. With other words, Nobu was someone who could move the masses with her charisma and aura alone with just words and she was a complete battle maniac. A very explosive combination. Of course Yu wanted to kill them all around the world, but the servant would agree on that if it meant her conquering territories beyond Japan on the mainland and annecting them to her nation.

Yu quickly found the reason for Shinoa's earlier scream leaning against the wall with only a towel around the waist. Pink hair and a delicate face made the man look quite feminine, but the lack of female feature on his bare chest was more than enough evidence to determine his gender.

"Oh hey Yu-kun." The servant Rider greeted the black haired boy, while still leaning against the wall. Astolfo as he was called was someone who Yu immediately got along very fast. His joyful, happy go lucky persona made him easy to approach and even though Nobu understood Yu's motives and feelings better, Astolfo was the Kind of Person that could turn a room as gloomy as a funeral with enough time into a lively party.

Which left one question in the room...

"Why are you outside Shinoa's room?" Yu asked, making Astolfo smiling sheepish at him.

"Well I wanted to take a shower, but Shinoa was still asleep so I snuck out the room. When I came back I was about to change back into my clothes when she woke up. And then she threw me out for no reason really." Astolfo said, smiling the whole time, while Scratching the back of his head. Yu however had an idea why Shinoa flipped out like that. It probably was because Shinoa had not known until now that Astolfo was actually a man. He didn't blame her for that one. After all, Astolfo looked very feminine with his slender body, limbs and his pink hair. "Oh well. I'll just wait until she cools off." The rider servant said as he grabbed the towel around his waist and put it around the back of his neck.

"Hey can't you be a bit more quiet?" An annoyed voice said behind Yu as he turned around. It was Mitsuba Sangu, also a member of the Shinoa Squad and apparently she was not a in a very good mood. Probably she was woken up by Shinoa as well.

"Oh hey Mitsuba. Nice meeting you this early." Astolfo said as he greeted the blonde haired girl. Time seemed to slow down as the rider took a step to the side to greet her. Until now Yu had blocked Mitsuba's view on the servant, but now she got the full view. Mitsuba's face turned crimson within a millisecond as Astolfo still had the towel around his neck and not his waist anymore. "Mhm? Is something the matter?" The servant asked perplexed by the girl's face expression. Meanwhile Mitsuba's eyes went down and down to a certain part of the servant's body. Until all that tension in the air was released.

"IIIIAAAAHHHH!?" Mistuba's scream reached even Guren in his office. After that everyone in the JIDA HQ was probably awake.

In the next moment the door to Yu's room was slammed open as a fully dressed Oda Nobunaga was Standing there with her sword on her shoulder. And boy she looked pissed.

"SHUT YOUR DAMN TRAPS ALREADY! THIS EMPEROR IS TRYING TO SLEEP!" She roared. Her red eyes seemed to glow as she turned her head to the other people in the hallway and quickly pieced together the reason for the disruption of her wellearned sleep. Summoning a multitude of guns in the air around her to the point where behind her a wall of gun Barrels seemed to have formed she glared at the naked Rider, the furiously blushing blonde and the dead pale boys. Then the guns charged up. quickly the three tried to run away but in a straight hallway that was basically impossible.

BOOOOOOM!

"AHHHH!?" Rider yelled as he was launched out of the building with the explosion, that left a large gaping hole in it. As for Yu and Mitsuba, they were tightly pressing themselves against a wall, ending up with Yu being in front of the blonde as if he could have shielded her from the explosion. The large explosion rang through the JIDA HQ upon Archer using her noble phantasm. Now not only all of the JIDA HQ must definitely be awake, but most likely all of Tokyo must as well. And it was just a normal morning in this destroyed world.

Yu only hoped he was not the only one with a troublesome servant.

Mika was frozen in shock at the picture before him.

Several vampires were pinned against the walls around him with several cut wounds on their bodies. Their clothes were removed and their bodies mutilated in horrible manners. Fingers were cut off, tongues removed, teeth smashed in. Some parts of flesh were scorched black, revealing burnt muscle tissue. Several iron pins kept the victims on the wall like preparated insects. Some of the pins were bloody but held no more victim as a small pile of ash on the ground beneath told Mika what had happened with them. Bloodied torture instruments laid scattered across the ground ranging from scalpels and pliers to burning irons and those pins. The majority of vampires were male, but there were also some women among them. In general was the ratio more shifted in favor for male than female individuals among the vampire's ranks.

And then there was the blood. It was everywhere. On the floor, the walls and all around him the iron stench of blood engulfed Mika like a thick fog, clouding his senses by simply breathing. The small rivers of blood converged into one single place: Lancer's bathtub. The servant seemed to have no shame at all as she was currently laying back in her bathtub full of blood as she scrubbed her body with the red liquid, humming innocently to herself. The sponge was drenched in the blood of those she had killed, making streams of the crimson liquid pour out like small waterfalls, before scrubbing her body again. Her tail with the split end was peeking out the bathtub as well in a not caring manner. The blood on the dark scales almost gave Mika the impression of a sea serpent, but the split, violet colored tip made it look like the tail of a mermaid.

Almost unconciously Mika approached the lancer, though his mind screamed at him not to. But he could not help it. All that blood running down her shoulders and dripping from her hair made the sight before him only more alluring. It was as if a switch in his brain was flipped and his rational side was shutting down, leaving him with his instincts. Lancer looked back at him and shot him a smile. Mikaela's mind screamed at him not go any further, but he was already standing next to the bathtub as his hand reached out for the servant.

And then Mikaela woke up with a startle. He panted a lot as if he woke up from a nightmare. A hand gripped his chest where his heart used to beat, but it was a habit that simply didn't die that easily.

"I see you are awake." A familiar voice next to him. Turning to the voice, Mikaela saw Krul with a frown on her face. Only now Mika realized that he was laying inside a bed in a room he didn't know.

"What... happened?" Mikaela said. Krul sighed at the pitiful state her pet was in as she sat on the edge of the bed.

"After we found you and Lancer you got knocked unconscious at some point. Unfortunately she managed to Escape." Krul said with Irritation in her voice clearly visible. "You really should discipline more unless you want her to do that again. She killed several good fighters among our ranks just for that bath of hers." Krul said.

"So that was not just a nightmare…" Mika's hand landed in his face as he tried to force the thoughts back from that dream, no that memory of his servant having killed several low rank vampires for a literal bloodbath.

"Unfortunately no." Krul sighed. "Well since she is your servant we'll have to punish you though. We can't let her act as she pleases and since she's too strong for us to handle we'll have to use you." The queen said as Mika cursed his bad luck. But then something stirred beside him under the sheets. After some shuffling a certain servant's head peeked out from the covers and looked at Krul.

"You're noisy. Be quiet." She said annoyed. Krul and Mika gaped at Elizabeth for a moment as the information before their eyes sunk deep inside their brains as the wanted lancer servant Elizabeth Bathory was laying next to Mika the whole time and given how she was covering herself with the blanket as she sat up, she was butt naked. Immediately the faces of the two vampires turned crimson. One from anger and one from embarrassment.

"W-What..."

"WHAT THE HELL DO YOU THINK YOU ARE DOING HERE LIKE THAT?!" Krul cut Mikaela off as Elizabeth chuckled. An evil glint was in her eyes as she wrapped one arm all around Mikaela's shoulder, while tracing one claw over his chest in small circles, causing Mikaela's blush to deepen. it didn't draw blood but the fact that Elizabeth's digits were all sharp claws as well as being surprisingly cool, made the blonde hiss a little as the edge traced across his Skin.

"Ah~ What's wrong Krul? Are you jealous? Such an unbefitting behavior for a queen." The servant giggled as she pressed herself more against Mikaela and Krul's face began to glow redder than before as well. The servant's tail slipped around Mikaela's thigh as it created a visible uplift of the blanket.

"You dare to hide here after what you have done? I should kill you right here and now!" Krul said Ready to pounce on Lancer. The tension however was disturbed by Chess Bell entering the room.

"Elizabeth! You said we are going to meet like a minute ago!" The bluenette vampire said. The servant giggled as she suddenly stood up and threw the blanket away. Mika was suddenly flipped on his stomach by the tail coiled around his thigh as he groaned. On his back stood a somehow fully dressed Lancer in her usual black idol dress before she jumped off the bed, using Mika as a launching pad and landing between the door and the bed. Not that Mikaela was not happy for Lancer to at least get along with one vampire in the city. So far her interactions always ended like in a weird cartoon.

Whenever Ferid tried approaching her, she almost killed him. Probably due to Ferid being a creep.

When Crowley tried to be nice to her, she called him a pig, which she Apparently did with all male individuals including Mika. Horn even tried to attack her, only to be almost beheaded by the lancer. Crowley simply shrugged it off and still acted like a Gentleman, thugh Mika could tell he was annoyed deep down.

And when Krul gave her orders it would always end with the two fighting on the ground, pulling at each other's hair and throwing insults left and right to the point where Mika didn't even try to separated them anymore as he'd only receive a kick in the chest or against his chin. So instead of staying there to 'see the show' as Ferid called it, Mika simply acted mature, turned around and walked away, leaving the vampire queen and the servant to clash it out themselves.

But when she met Chess the two got along so fast, Mika could have mistaken them as normal human girls that have been Friends since childhood. Also it might have something to do with both of their normally childish behavior and Chess' newfound love for Idols, which made the lancer basically a role model for herself.

"Sorry, but it seems like this Idol Needs to assist her kohai.

"Huh! But I don't wanna be he kohai!" Chess said in protest.

"Lancer, what you did was not okay at all. So you will not run away and cause more Trouble for everyone." Mikaela said as he tried to show some dominance when he stood up from the bed. However the moment he did he noticed something very important. Or rather something very important missing. The three Women's eyes looked at Mikaela, before trailing downwards like Mika looked down himself.

Krul's face became one of annoyance as she clenched her hand into a fist forcing a strained smile on her lips.

Chess' cheeks were heating up at this point where they were matching her eye color and her mouth seemed to try to say something, yet was unable to bring any real words out through her mumbling to herself.

And much to Mika's Horror, Ferid suddenly stood next to Bell in the door as both the progenitor and the servant with the shared family name looked at the same spot as everyone else with a cunning smile and an mischievous glint in their eyes, while putting a hand on their chins.

"My, my~ Didn't thought master/Mika-chan was hiding something like that." The two Bathorys said in perfect sync as Mika finally realized that he was not wearing underwear.

"Eh? What the-" Mika was silenced by Krul's fist slamming into his face.

"YOU PERVERT!?" Krul's shout shook the entire city as Mikaela was knocked out for good again. Mika asked himself what he did wrong in his last life to deserve this as he was sure he had done nothing wrong in this one yet. He just hoped Yu was fine.

Yu was rubbing the red imprint of Mitsuba's hand on his cheek after she slapped him in the face that morning. It turns out that shielding a tsundere like her like he used to only caused her to blush, scream and slap him only to hide her own embarrassment. And as for Rider, he was surprisingly fine after falling out of the 3rd Floor. Shinoa was nice enough to let him get back in the room to put his clothes back on, though she still shot her servant a glare that said as much as "Don't get anywhere near me, you creep." or something like this. Astolfo for his part shrugged it off as well as Nobu's attack as he stll laughed about it.

And as for Oda Nobunaga, she had to explain to Guren why she did what she had done, though it was more like her telling her side of the tale instead of a formal report as she refused to see Guren as he superior, something that angered the Guren Squad or rather the three women in it, but since Nobu was the kind of person that would keep acting the way she was until someone pushed her back, there was literally nothing the girls could do as Nobu would simply have shot them into pieces if they did as much as lift a weapon against the demon emperor of Japan.

"Say Shinoa," Yu asked as the 3 members of the Shinoa Squad or the "Crimson Squad of the Demon Emperor" as Nobunaga would call it were walking in an awkward silence through the HQ of the JIDA to get the Kimizuchi and Yoichi while the two heroic spirits tagged along in the back. "I know we summoned Rider and Archer, but how exactly did we do it? My memories seem to have holes about what I did." Yu said. Shinoa put a finger on her chin as she hummed to herself.

"Well we were at an abandoned museum when we were looking for any clue of vampire activity over there. Then we stumbled over a collection of objects within the cellar and when you were looking around for something you somehow managed to knock over all shelves. The next thing we know is Rider and Astolfo being there." Shinoa summarized as Yu listened to her with one ear.

"Why must my master be someone who summons me the great Oda Nobunaga per coincidence?" Nobu sighed as she materialized next to Shinoa. Then suddenly she stiffened up and jumped over Yu and Mitsuba in the front as she blocks the way.

"Archer?!" Yu looked shocked and confused at his servant. Before he could continue, Astolfo materialized next to Shinoa.

"I can feel the presence of another servant. It must have been summoned just now, because the amount of prana it emitts is enourmous." Astolfo said as he drew his Sword.

"Things finally get a little more interesting in this unusual grail war. But if that servant looks for a fight, I'll be happy to be its opponent." Archer said. As if on cue, the door of Yoichi's room at the end of the hall suddenly flew out its hinges and smashed against the opposite wall, exploding into splinters. The Shinoa Squad drew their weapons as they suddenly felt a dark and suffucating presence. It was like a thick fog, which literally crawled out of Yoichi's room as it clung to an unusual being.

Clad from head to toe in a medival looking knight armor and having a single visor that glowed in a deep red color, the servant stepped towards the squad, while a deep growl escaped its throat. Yu, Mitsuba and Shinoa immediately felt the difference in power between them and their opponent. This one was not someone to be taken lightly at all.

"Ha... Just our luck." Rider said.

"Astolfo-cha... Rider, what do you mean?" Shinoa corrected herself.

"Simple. This guy is a Berserker class servant. The strongest kind of servant when it comes to raw power. And it looks like he's Looking for a fight." Oda said as she drew her sword. The Berserker meanwhile stood in the hallway unmoving. It was unsettling as the deep red visor would have made anyone sane uneasy. It was like a predator observing its prey from afar.

"AAAAAARRRRRHHHHHH!" Berserker let out a roar/howl of rage as he dashed towards the Shinoa Squad in a blind rage, destroying the walls in the hallway by simply running in it with its big and broad armor. Archer and Rider were ready to protect their masters when...

"Berserker, stop!" Yoichi came out of his room and thrusted his right arm at the servant. A red wave was emitted from one of the command seals as it vanished. Berserker stoopped dead in his tracks as he glared or just looked confused at his master. It was hard to tell with the helmet on. Following Yoichi was Kimizuchi who looked quite unsurprised to see Yu among the people Berserker wanted to kill. There was quite the awkward silence in the air again.

5 minutes later they were all inside Yoichi's room.

"So you summoned him by accident as well, but you wanted to ask Kimizuchi for advice instead of asking us?" Shinoa concluded what she just heard.

"I'm very sorry." Yoichi looked down.

"Don't be. This is still uncharted territory for all of us." Yu said.

"So does your servant have a name except his class?" Mitsuba asked. Then Berserker glared at the blonde as if he wanted to behead her with his eyes alone, making Mitsuba recoil visibly under his gaze.

"It's fine Berserker. He didn't tell me his name yet, but I'm sure he must be some legendary hero if he got summoned as a servant." Yoichi said.

"A servant that doesn't tell his master their true name? Looks for me more like someone not trusting you boy." Oda said, earning her a glare from Berserker, which she countered with an arrogant grin.

"Hey let's not fight now. We still are on the same side and when he's a hero then I have no reason to fight him anyway." Astolfo said thrusting his fist into the air. The others of the Shinoa Squad could see why Shinoa had thought that Astolfo was a girl. "So welcome to this Family of misfits, Berserker!" The rider said. Berserker didn't react at all, much to the amusement of Oda Nobunaga and the sadness of Astolfo.

In that moment the Shinoa Squad asked itself, whether they could manage to survive with this colorful mixture of servants or not. And who the other masters and servants might be.

At the same time something was going on somewhere far away that would leave most people terrified.

Deep down in the subterrean labs of the JIDA was a person restrained against a wall. The machine in front of it hummed to life as archs of electricity reached out to the being. It was a young woman, which remained stoic at the discharge, which would kill normal human beings. But this being was neither normal nor was it human. Her hair had a pale shade of platinum blonde, which was tied in neat bun. Her body was covered in black armor and a black and red visor covered the upper half of her face. And her skin had a unhealthy looking pale color.

Silently she cursed the man she had to call her master, a black haired man flanked by a blonde woman who stood above the platform she was one as they looked through a bulletproof window at her as the experiment continued. Next to them, people sat on consoles and computers, operating the machine and observing the experiment for any changes of the subject that was her.

She didn't know why they wanted her to undergo these experiments. She didn't know why he performed them on her in the first place when there was nothing to gain from it except her scorn. But she knew only one thing for certain.

Once there was the possibility at hand, she would slay the man that had chained her down here like a beast and experimented on like a lab rat. She may had been restrained by a command seal, but her anger burned stronger than this. She who had endured all kinds of battles, far more horrofying than what the world was like now, was not going to cave in from such weak attempts to break her. She was already used to betrayal by now. But she would never forgive anyone who betrayed her and so she'd end this man. That she swore by her honor as a knight and as a king.

And that's it. The twoshot is over. Now Zelretch has actually something new to observe.

Hey guys, that was the last chapter of this OnS/Fate twoshot. I had expected it to get together sooner, but it simply didn't want to be. Originally it was supposed to be a Yu and Oda Nobunaga solo part like the first chapter with Mikaela and Elizabeth, but that would have been too short so I added more unused material into the mix here.

Ireceived more reviews than I had expected to be honest and I want to thank all the people that made those suggestions. Because that shows me that you people actually got inspired and thought about possible constellations of potential masters and servants. And basically that is the whole purpose of it all.

For you see, I actually would love to see a good Fate/Seraph of the End crossover that is taken seriously to the end of the story, but unfortunately I have not found that many crossovers of this at all, which surprised me to be honest. And that got me thinking. Why instead of making a challenge, not make a oneshot that is a) read by more people and thus have a higher chance of infecting someone with that idea (Insert Inception music) and b) is far more fun to write than a simply list of arguments for a story?

And it worked review-wise better than I had hoped for it to do. The servant and master pair for this story were already made before so the fact that Yoichi got Lancelot and Shinoa got Astolfo (of all people) has nothing to do with someone suggesting anything. I simply thought it was funny.

I hope you enjoyed this second installment and the character interactions with one another. I must confess a lot of it is on crack and OOC, but it was still funny to picture when I was writing this one down like the female vampires' (and Ferid's) reaction on a Mikaela without pants. I hope I managed to inspire the one or two of you to write your own Seraph of the End/Fate stories and again thank you for all your ideas and partaking in this small project of mine.

So until next time, have a nice day.
