Fate/Grand Order: Where All Miracles Begin, SCHALE

Prologue (1/2)

"Sei—"

"Sensei. Wake up."

"Ritsuka Sensei!" The sharp voice raises its volume. And more importantly, as my first name was called, I instinctively woke up.

"..."

"..." In front of me was a composed, elegant girl. Her silken dark black hair cascaded down her back as it glinted in lapis blue when the morning sunlight shone upon them. She dressed in all white, nonetheless, the formal attire she wore did not dim her glow in the slightest. Her sharp azure eyes stared at me through the glasses. Now that I had taken a good look, she seemed very reliable.

"You fell asleep after I asked you to wait here. I even had some trouble waking you up... I didn't expet you to be so sound asleep."

"You must have been having a dream. Anyway, gather yourself and focus..."

"Let me explain the current situation again." She said as she tucked her hair behind her elvish ear.

Yes, I fell asleep, very deep too.

As for what was happening at the moment, Well— It all began when...

.

"Senpai."

"Hmm?" I answered as a soothing voice called out. Next to me, walking by my side was my underclassman who had been together since day one, Mash Kyrielight. Despite her cute and gentle appearance, she was a very hardworking and strong girl.

"Finally, to think that we'll get to return to Antarctica. This meeting we're going to attend will discuss a lot of details on what our roles are when we reclaim our home."

"Since the lostbelts are all erased and no alien god apostles are left, the operation has a high chance of encountering no hostile enemies and probably be successful!"

"Many battles and lives came before us to bring today. This time our journey is almost a its end... let's go, Senpai!"

"Mhm! Let's go!" I replied, my eyes warmly looking at her pink head bobbing up and down as we walked in the hallway.

"Senpai, looks like Kadoc-san and both Hakuno-san are already in the meeting room already. Let's hurry!" Mash said excitedly, her delicate hand grasped my sleeve as she quickened the pace.

Like Mash said, our next mission would probably lead us to the real conclusion of the grand order we'd been through for almost 3 years. My name is Fujimaru Ritsuka, a master of Chaldea whose role was to command servants in battles. Throughout these 3 years, we faced many unimaginable threats whether they were humans, gods, or even extraterrestrial beings.

Chaldea, wherever it was, had become home to me. Despite all hardship and dangers, all these people, from staffs to servants, gave me all the courage and determination to finish the Grand Order.

"..." Now that I thought about it, our organization had grown so much. From our first summon, Emiya, to hundreds of heroic and divine spirits, we had indeed come a long way. We even had more masters, Kadoc and the Hakunos. Tezacatlipoca even said Daybit, the previous and the last crypter, would join us before we entered Antarctica.

Hmmm If it's him, will he just appear on the storm border? Or do we need to pick him up somewhere?

Anyways, It would be great if the Grand Order would fini

"Ritsu! What takes you so long? —Aha, I know it. You want your senpai to accompany you right?" Cutting my thoughts, I felt a soft sensation as my arms were locked into a delicate pair of bodily pillows.

"H—Hakuno senpai?"

"Eh?! Ha—Hakuno-san?! Aren't you already in the meeting room?" Mash exclaimed, her eyes looked at our locked armed.

"Well, yes, but my adorable kouhai somehow still never showed up, so I immediately knew he needed my company." The girl answered happily. Her name is Hakuno Kishinami, previously was a master of the moon, now a servant in the Moon Cancer class.

'My relationship with Master... is it like we're rivals, best friends, and siblings? I could tell you how I feel, but I'm afraid it would just cause trouble for everyone else, so I'll keep quiet.' That's what she said. But now that she did that in public—

"I told you to not turn your eyes toward other servants. I am your only lover, ne?"

"—!" Without knowing it, my other arm lost its freedom. I could also feel a soft baby cheek on my shoulder.

"Tenochtitlan-san?!"

"My kouhai doesn't need a traitor to be his lover much less for his servant." Hakuno threw out the first jab.

"Well, who wouldn't have if it came with a land, a house, and an official marriage contract with all venues and honeymoons prepared?"

"You two—Please! Senpai needs to attend the meeting!"

Mash tried her best to stop this whole situation. Occupying my right was a stubborn, competitive senpai. Occupying my left was an Aztec city who never missed any opportunity. Mash—she was my only single hope to stop the conflict before it got out of ha—

Bump!Something suddenly attached to my back.

"..."

"..."

"..."

"I just heard someone had a lover, so I suddenly missed you sooo~ much."

"..."

"I'm weak against loneliness, I lack confidence, and I want to keep seeing you 24 hours per day."

"..."

"And if I'm left alone, I will start wanting to burn down the entire Chaldea..."

"..."Ah, here we go again, I thought as I also started to feel a rising temperature in the atmosphere.

However, it didn't come from the little dragon sticking with my back. Instead, it came from a corner of the hallway. Not so far away, a silhouette was engulfed in an eye-catching blue flame, her mouth kept mumbling nonstop.

"Burn... Burn inside a bell..."

After Grand Order, it looked like there were a lot of things left to sort out. Yes, my relationships. A spider would give me a run for its money if they were to be displayed in a diagram.

To be the master who housed so many servants, I subconsciously developed and honed my social skills to get along with everyone good or evil. But to think that their affections would reach this degree plus for a person who was weak against their advances, that was how I ended up in this mess.

"Calm down! Everyone! Pleaseeee—"

"Kouhai! Say it— You surely prefer a lovely and considerate senpai right?"

"Shut it, Tlamacazqui serves me! I'm a place he calls home!"

"Since lover and husband are two different categories, I already received the royal permission from the High Queen—!"

"I won't let you run... If we die together..."

"..." Thinking about it made my head hurt. Suddenly, dizziness clouded my mind as my legs gave out strength.This feelingagain!With this familiar sensation, my eyelids became heavy and I started to faint. With the remaining strength, I tried to outstretch my hand to Mash. However, with both my arms locked, I couldn't do anything but let my body fall.

"Senpai!—It's REM REM again! Sen—"

"Ehh! Ritsu! Is this my fault?!"

"Tlamacazqui!—"

"Call —the med—! Senpa— P—Hang in t—"

I heard their panic voices as my consciousness faded away.

And there it was, how I got transported into this world.

I also dreamt of the General Student Council president who happened to be there when I first woke up too. After we discussed a few topics, I spent a few days coping in my room, gathering and investigating lots of information. Without Mash who was generally a lot cleverer than me, I spent days and nights researching that I barely scrapped together sleep.

How many hours of sleep did I get last night? 3 or 4 perhaps?

I tried to force my eyes open despite all the sting when the brightness cut sharp against them.

"My name is Nanakami Rin, and I'm a General Student Council officer from Kivotos, the academy city."

"And you're a teacher that we have summoned here... or so it would seem."

"Pardon my uncertainty, but I only say that because I still don't fully understand how you got here."

"..." I nodded slightly as the girl introduced herself. It was expected that the details I shared with General Student Council (GSC) President were confidential, thus Rin did not know anything regarding my true identity and my goal.

Moreover, there had been a rumor going on around the city too. The GSC president had disappeared out of thin air, losing my accomplice in a few days was absolutely a great start.

"Welcome to Kivotos, Sensei."

"Kivotos is a massive city, home to thousands of academies. This is where you'll be working from now on."

In front of me was the vast expanse of the entire Kivotos, the modern city filled with high-rise buildings and towering skyscrapers. Their sleek glass surfaces reflect the clear blue sky, a river winded its way through the urban jungle, adding a serene touch to the bustling scene and vibrant pulse of life within the city. As the elevator went up, the cityscape looked even more beautiful.

"It's bound to be very different from the place you call home. You might find it difficult to fit in at first... but something tells me that you will adjust in due time."

"After all, you were chosen by the General Student Council president. We can leave the rest of the details for later."

"Thank you, Rin. I appreciate your concern and your warm welcome." I responded.

Guns, Halos, Students,... As a Master of Humanity whose role was to resolve a singularity, there were so many mysteries in this city. To begin with, the number of academies here skyrocketed, it was not even exaggerated to be shocked by how many they have. It was a weird glimpse but—why did it look like the city was trying to mass-produce students?

Secondly, what are 'students'? As far as I was concerned, there were no normal human being in this world. The closest to the human species are the 'students'. They even had halos. They knew their existence but never knew what their halo or other looked like.

But I could see it.

"..."

"..." A blue ring of light rested gently above the girl's head. With its crown pattern, it gave the elvish girl an air of authority and grace, contrasting perfectly with her sharp and elegant demeanor.

"..."

"Is there something on my face?"

"Ahh.. No, it's nothing." Perhaps, I had stared at her halo for too long. Nonetheless, throughout our conversation, I had always felt a sharp gaze piercing me. Rin had been assessing me heavily as expected.

DiiingEchoed the ring sound as the elevator came to a stop. I walked with Rin as we went straight to the reception room, only to be greeted by 4 newcomers.

"There you are, Acting President! We've been waiting! Get the real president in here already!"

"I've been waiting to see you, Chief Officer."

"I'm here to meet with the General Student Council president. The head prefect has terms she would like to discuss." Not giving any spare second to react, Rin was immediately bombarded with questions.

"Well... This timing is rather inconvenient." Rin said with an annoyed sigh. I could even sense her calm and collecting aura dispersed, replacing with a cloudy one of course.

"Hello, guests that represent neighboring academies' student councils, disciplinary boards, and those who otherwise have too much time on their hands." Rin continued, her slender fingers tucked the jet-black hair behind her ear.

"Well, I'm aware why you irksome—I mean, important representatives have come here today."

"You're here to blame us for the fuss happening in the academy city, isn't that right?" Rin concluded with a little smirk.

"If you're well aware, then do something! You represent the General Student Council after all! Thousands of academy districts are in a panic! Our academy's wind generator shut down just a few days ago!" The first girl whined. Soon, more issues were voiced by the others.

Letting them verbally engage, I quietly listened. More illegal distribution of wartime equipment and a sharp increase in public assaults.

Haa—No matter if one looked at it, this city was indeed weird. The students were the core of the city, they took the role of management themselves.Isn't this too much for them? What's the deal with concepts of this world?There were no normal humans, they became historical figures and only appeared in texts and images. The city was only filled with demi-human and AI robots, the students also had lots of distinctive traits.

And they also carry real guns...

Ever since I appeared here, I swearI have always felt the Moon Dubai's vibe all over the place.

With lostbelts and singularities experience, I could make an educated hypothesis in an instant... Humans lost their place as the prime species and disappeared from the surface of this planet.

"Sensei here is the answer to our problems."

"?!"

"..!"

"This person?" The four girls followed Rin's hand and looked at me in surprise. The disappearance of the GSC president, the appearance of a man of unknown origin, and the man himself suddenly became the key to the city's lost authority. Well—maybe it was a little too much to take in for them.

"Hold up. Who is this 'Sensei' you're talking about? What is he doing here in the first place?"

"Whoever he is, he doesn't seem to be from Kivotos."

They all looked at me, their eyes scanned from head to toe.

Humanity's last master was bad enough, now I became Humanity's last human?

"This is Ritsuka Sensei. Not only is he going to be teaching in Kivotos, but he's also been personally selected by the General Student Council president." Rin introduced, this world went with the first name basis.

"The president chose him. The one who's now missing? Things are making less and less sense..." A girl mumbled with a sour face.

"Hi, everyone. I'm Fujimaru Ritsuka, glad to meet you all." I happily greeted them, their openly confused faces were indeed pleasant to the eyes. They might have put up some serious acts but they all looked very innocent to me.

"R—Right. It's good to meet you, Sensei. I'm Millenium Science School's... I—I mean! Why am I even bothering to introduce myself right now?!"

"Don't worry about that annoying girl. Let's just move on—" Rin cut in with a devilish smile.

"Who are you calling annoying?! I'm Hayase Yuuka! You should remember that name Sensei!" The girl who flinched just a second ago now was cutely stomping her little feet up and down in frustration. Her twin tails flutter, and her black and white suit-liked uniform create a striking contrast with her adorable face. From the first impression, she looked very—very tsundere. If I were to compare... Ishtar? But more serious and less problematic.

"Well.. It's nice to meet you, Yuuka."

"You're here to serve as the advisor for a club that was formed by the General Student Council president."

"The Federal Investigation Club: S.C.H.A.L.E." Rin explained, including the details on SCHALE's authority over any organization. I could only smile dryly and thank the GSC president for aiding me in investigating this world... or perhaps, a singularity.

Just when Rin was about to call for a transporting helicopter, her colleague over the phone reported her wreaking havoc by an escaped student from the Correction Bureau. Several thugs and a tank were rallied in the area, they were trying to occupy the SCHALE Building.

"..." With both eyebrows joined, Rin sighed annoyingly.

"Are you okay? Deep breaths, Rin. Deep breaths." Standing next to her side made me overhear their conversation. I gently put my hand on her shoulder, reassuring the poor girl.

Although It had not been many days since I came to this world, I could see where it was going. I just couldn't accept it, a girl of her age should be enjoying her school life, not the responsibility of an organization much less an entire city.

But... to rob her of the position was out of the question, it would also harm her pride.

What I could do, was to assist her. With the officially announced 'Teacher' role, to assist the students.

"I'm fine... It's just a minor setback. No problem at all." Rin replied, trying her best to control her stress. The past few days without the GSC president must be a ruckus.

"..."

"...?"

"What? Why are you looking at us like that?" Yuuka stepped back, noticing Rin's mischievous stare. The latter's mouth curled up into a slight grin.

"It's so reassuring to have you trustworthy academy representatives here with us."

"Huh?" Yuuka cried out in an instant, Rin's eyes focusing on her couldn't feel more wrong.

"We are going to need your help to bring peace back to Kivotos, Let's go." The elvish girl answered, turned around, and walked away. Each of those took one second.

"Wait, what? Where are we going?!"

With that, Rin forcefully led the crew to the crime scene...

BOOOM!Bang Bang Bang Bang!

Bang Bang Bang BangCRAAAASH!

"Wha—What's going on?!"

Bang Bang Bang Bang!

"Why do we have to be the ones to fight them?!" Under the gunfire noise, Yuuka rebuked. Following Rin's direction, we were now at the outskirts of the District of Utnapishtim. However, the area was off—limited as a group of thugs were rumbling around with machine guns.

"Rin said defending the club room is paramount if they're to regain control of Sanctum Tower."

"I get that, but I belong to my school's student council! Why is a busy work like this falling to me?" Yuuka continued to throw tantrums.

Bang Bang Bang Bang!

"Ah, that's smarts! What the heck! Are they using JHP rounds? That's cheating!" The whiny girl yelled in vexation as she got a direct hit when she peeked out of the cover.

"..." I let out a relieved sigh. From my research, students in this city brawled with guns and literal bombs. The situation in my vision significantly proved it. Plus, a student could really tank bullets. There was no blood, just a little red skin and a scratch that instantly healed.

As if... the damage is transferred to the halos.

"We need to remember that Sensei is here with us. His safety is our top priority. Reclaiming the building will come second."

"Hasumi is right. Sensei isn't from Kivotos. Unlike us, a single bullet could put Sensei in grave danger. Don't forget that!" The girl in red medic attire argued after the girl in black uniform.

"I know that! You can't join us on the battlefield, Sensei, so stay put while we take care of this!" Yuuka and the other two looked at me behind them.

In front of me were the four girls who visited the office, they were taking cover while returning fire to the thugs. With a pistol in hand, Rin crouched beside me while busily requesting reinforcement.

"Rin, it's okay—You can relax."

"Sensei?" Our gazes met. Despite her cool, strong upfront, I could still see worry and confusion in her eyes.

Even though these thugs had dangerous firearms, it was not like I had not encountered a situation like this either. The Shinjuku delinquents were a lot more wild and menace.

"I'll take command. Trust me."

END.

Author's notes

In the end, I decided to have both Hakunos in Chaldea. I found the female Hakunon and Master a very god pairing. The strongest polygamist in history vs the strongest polygamist of today. Lol. See you next chapter!

Explanation

- Tenochtitlan called Fujimaru 'Tlamacazqui' which means 'priest'. As a personification of Aztec city and the divine spirit Tlaloc, she indeed needs a priest (lover).
