I'm gonna keep this short so no time is wasted.

There will be an OC, and there will be some OC x Reimu. Before you leave, let me say that the relationship won't be prominent, Reimu won't be doting on him, and the OC won't be showing up often, if not simply rarely.

Oh, also memes incoming.

That's all.

Are You My Master?

"Yo Reimu!"

Reimu sighed and looked at the shrine entrance, where a witch dressed in black and white stood, grinning.

"Hello, Marisa," Reimu said dully. She was tired from dealing with the fairies earlier that day and tried to convey her tiredness into her voice.

Of course Marisa didn't care.

"Check this out!" she said proudly, holding out something for Reimu to see.

A rainbow-colored crystal, pointed on all sides. It looked to the shrine maiden like a toy.

"Cool rock," Reimu grunted.

Marisa huffed, put her hands on her hips, and said, "It's not a rock, Reimu. It's a Saint Quartz."

"Cool."

"I got it from Kourin! He said that Saint Quartzes summon famous people from the Outside World, and they will become our Servants and us their Masters! Granted, in the Outside World you need a 'catalyst' or something yadda yadda Saint Quartzes are how we get them here!"

Reimu gave Marisa a sideways look and asked, "Why do you care so much?"

"You didn't see the Servant who was standing next to him... I think he said his name was 'Sigurd' or something."

Submitting to the fact that Marisa was not going to drop the subject, Reimu asked, "So, what are you going to do?"

Marisa pulled chalk out of her bag and said, "Summon a Servant, ze!"

She drew right on the ground, and Reimu felt a jolt of alarm.

"Hey, don't draw on the floor!" Reimu screeched.

Too late, Marisa drew a circle on the Hakurei Shrine's floorboards and tossed the chalk behind her. She then raised the Saint Quartz above her head.

"Now, to summon a Servant!" she shouted and tossed the Saint Quartz into the middle of the circle.

It made a thunk sound against the floor.

And a girl crashed through the roof and onto the circle.

Both Reimu and Marisa stared at the girl who had just suddenly been 'summoned.' They then looked at each other before turning back to the unmoving girl.

Blonde hair pulled up into a bun, a blue European dress covered in English plate armor, and a gold and blue sword in her hand.

Not a Gensokian.

Slowly, the girl got up, groaning. She rubbed her head and looked up at both Reimu and Marisa. Then she spoke.

"You're not my Master."

.

Girls do their best now and are preparing. Please wait warmly until it is ready.

.

She went by the name "Saber," which was apparently her 'Servant class.'

"My Master had been taken, and now I must return to my own world to find him," she explained simply.

"You mean the Outside World?" Marisa asked.

Saber nodded, and then turned to the fuming Reimu.

"Is something wrong?" she asked.

Reimu gave a sarcastic laugh before responding, "No, it's not like you broke my roof and my floor!"

"I'll find a way to fix it later."

"Why later?!"

Saber's stomach growled. Reimu growled back. Saber's stomach didn't like that and roared.

Marisa put her hands up and said, "I'm outta here, ze." She walked around the crater, walked outside, and then shouted, "Oy, Reimu! I could use some help here!"

Unhappy at how her day was going, Reimu walked outside to assist Marisa, and her day got even worse.

"Hello there, Hakurei Shrine!"

Seija Kijin was floating upside-down in front of the shrine gates, arms crossed and grinning. Standing two steps behind her was a man covered in Outside World combat equipment, his face obscured by his red hood.

"Oh, come on!" Reimu cried angrily. "I've had a bad enough day, so will you just get out of here?!"

Seija's grin grew wider, and it was clear that Reimu's complaints only made things worse. Clearly wanting to ruin Reimu's life, the amanojaku flipped back to her feet and casually strolled onto the Shrine grounds, the man with her following a few paces back. Glad to have an excuse to get rid of Seija, Reimu drew out her miko stick, and the unnamed man drew something from his belt and pointed it at her. Rinnosuke had something similar to it in his shop. He called it a 'gun.' It was a projectile weapon that fired metal objects called 'bullets.'

If one went through your skull, you would die immediately.

"Don't make Assassin have to get nasty," Seija said tauntingly, as if wanting Reimu to give the stranger an excuse to kill her. "Let me put this simply: that bullet flies faster than you."

Reimu narrowed her eyes at Seija, who was really starting to piss her off, and spat: "I thought you wanted all people to hate you."

Seija glanced at Assassin and back at Reimu before replying: "Yeah, but it sure is nice to have a Servant to help you out."

Reimu turned to Marisa, who was reaching for her Mini-Hakkero, and asked her, "When did Rinnosuke start selling these Saint Quartzes?"

"I got mine three days ago," Seija put in.

"Eh... he said last week, ze," Marisa responded.

"You didn't know?" Seija asked. "Everybody's been getting their own Servants for a while now."

No, Reimu didn't. Today was the latest she'd been out of the Shrine's grounds. Before then, she had been spending time trying to fix her roof.

Speaking of her broken roof...

Saber was pointing... mist at the Assassin. Her hand was firm, and her gaze was hard.

"You there!" she called. "What is your True Name?"

The Assassin didn't move at all. Though Reimu couldn't see his lips, it was clear that he hadn't said a single thing.

Saber's hold on her mist didn't waver. Nor the Assassin's on his gun.

"Seija Kijin!"

The sudden shout boomed through the Shrine grounds, and the blades of grass shook like a strong gust had met them.

"Move aside at once! Or do you wish to fall deeper into the black?"

Seija turned around, ready to give some witty comment of some sort, but then her face fell like... Saber through Reimu's roof.

Turning to Reimu, she flipped the bird before walking down the shrine steps. Assassin said nothing as he put his gun away and followed her.

Shiki Eiki stood there, her Rod of Remorse gripped tightly in her hands. Next to her was a tall, buff man in knight armor holding a sword at his side.

Saber clearly recognized the man next to Eiki, because her eyes widened as she said incredulously, "Sir Gawain? Is that you?"

Gawain smiled and bowed before replying, "It's good to see you, my king."

Marisa waggled her head in disbelief before spewing out, "You're a king?!"

Eiki clearly did not care about the conversation that was occurring around her, because she immediately told Reimu, "Reimu Hakurei, as the defender of Gensokyo, it is your duty to solve this chaos!"

Reimu could only blink, confused at what Eiki meant.

Eiki stared her in the face firmly before continuing, "There are multiple youkai, and fairies, I suppose, who have summoned Servants and have been creating chaos all over Gensokyo!"

The Shrine Maiden knew for a fact that she shouldn't be snapping back at the Yama who her teacher feared, but she still replied: "Then why don't you do it?"

"I'll fix your roof if you do."

"Deal."

Eiki seemed satisfied. Then she got out a roll of paper and said, "Okay, here are the youkai who need dealing with: First, Sekibanki the Rokurokobi, who has been terrorizing the outskirts of the Human Village. Then the ice fairy Cirno, who has been creating rather violent pranks on her fellow fairies. After her, you must deal with the Komeiji clan, who apparently has sent an army of Servants to tear down the plant life around their mansion. It's not pretty. Finally, Yuyuko Saigyouji has to be fought for... 'stealing an endless supply of food.' There. Are you up to the task?"

"If it means fixing my roof for free."

Saber spoke up and said, "I suppose I should accompany you, Miss Hakurei. I am experienced in fighting Servants."

Gawain added, "She is my king, and for good reason."

Reimu's gaze narrowed at Saber and she pondered for a bit. Then she finally decided, "Fine, but don't expect me to call you 'Your Majesty.'"

"I wouldn't have it any other way," Saber agreed.

Marisa puffed her chest and asked Eiki, "So, I gotta go too? Beat some baddies and crack jokes, amiright?"

Eiki stared at her before laughing.

"Goodness, no!" Eiki cried after laughing. "You'd probably destroy everything in the process."

The witch put her hands on her hips, wanting to argue but not finding anything good to use to shoot back at her.

Eiki looked from the witch, to the shrine maiden, to the Servant, and then nodded. "Good luck to all of you."

She then disappeared on the spot, and Gawain nodded to Saber before doing so as well.

Reimu turned to Saber and asked, "Shall we get started?"

Saber nodded.

Reimu took to the sky and began to fly towards the Human Village. Saber, though grounded, followed closely behind her.

Twiddling her thumbs for a bit, Marisa sat there in boredom before finally getting on her broom and flying away to buy groceries.
