A new idea! I just wanted a story where you have big-sister Reines. I had no choice but to create one myself, lol.

The time-line is after the Fourth Grail War. Shiro is still a young boy, while the MC is in England.

Pls Fav'N'Follow the story if you are interested!

HERE WE GO!

Chapter 1 The WORST wake-up call, EVER.

When you wake up, you don't feel like throwing up. At least, normal people don't.

I always minded my own business, doing my things, studying, working, exercising…you know the drill. I wasn't born different, no superpowers, nothing. I loved the Type-Moon franchises, though I wasn't a believer either.

Ok, ok. I know I'm spouting unimportant shit. What I'm trying to indicate here is that I'm just a random dude born in the 21st century, the age of science. Magic? That stuff only exists in the Harry Potter movies, Lord of the Rings, etc.

That was how the world supposed to be.

I remember drinking a lot last night, partially because I was stressed out, and partially because I was on holiday. I didn't drink too much-I know about health, and how drinking too much can cause serious symptoms such as brain damage.

Sad to say, that didn't explain why I suddenly fell unconscious, with my head stuck inside a toilet seat. Yes, gross. And no, I wasn't throwing up because of alcohol or any kind of chronic sickness.

That also didn't explain why a boy with blond hair and electric blue eyes were staring back at me from the murky water. Yes, my reflection from this cursed toilet seat. I felt something disgusting rush out from my mouth, burning my throat.

I was born as an Asian, my passport proved that. I also made sure that both of my parents were Asian people. Then why? Why do I look like this? Did somebody decide to drug me to operate a full-body surgery on me? No, first of all, why was my head in a toilet seat?

"Hah, our sleeping beauty woke up at last!", a squeaky voice jeered. High-pitched laughter joined in, hurting my poor, throbbing skull.

"Did you like our spa, princess?", another voice drawled.

I knelt on the ground as an excruciating streak of pain ran through my brain. It hurt so much. I felt the insides of my mouth bleed from the strength I was biting down. My hands balled into fists. Agony wracked through my every nerve, as if it was burnt with scorching fire.

'Remember.', voices echoed in my head. 'Remember who you are.'

I gasped for air, choking as a boy kicked my back. My forehead crashed into the toilet seat with a painful bang. Memories sprung to life, wildly chasing away my old ones and making way for the new ones.

My name is James El-Melloi Archibald, youngest of House El-Melloi, and brother to Reines El-Melloi Archisorte. Unlike my sister who was a prodigy, I had little talent in the ancestral magic; Volumen Hydrargyrum: Marrow of the Moon Spirit.

The most I could do was to morph the enchanted mercury into transformable weapons, and even at that, I wasn't proficient. I was the laughingstock of the Clocktower, and after Kayneth died in the Holy Grail War, there wasn't anyone except my non-biological sister who loved me.

"Hahaha! He truly is the trash of El-Melloi! He can't even fight back!", a voice mocked.

"No wonder House El-Melloi is suffering! With their astronomical debt…who knows, maybe Lady Reines would go open her legs for some rich lords?", another one guffawed stupidly.

I heard a crack run through my heart. My mind was clear and calm, like a silent lake. From their blind angle, I started to write runes onto the toilet. Runes that were on my mind for a long, long time. Theories I didn't even tell my sister.

"Hydrovolumen Hydrargyrum: Mirror of the Moon Spirit"

The chant came out in a soft whisper.

"Huh?", one of the bullies snarled. "What did you say, loser?"

I felt my mana activate. The water rippled. A smile broke through my face. I couldn't stop the chuckling that bubbled up from the depths of my stomach.

"I said this: How dare you inferiors talk about El-Melloi?"

Water materialized, gaining a metallic glow of polished silver. They erupted from the toilet, piercing into the bullies' beating heart. The curse ate through their flesh as it traveled through their blood, traversing into their very souls.

I stood up, swiping back my wet hair with a single fling of my head.

"My mage craft is now sealed within you. Try to reveal it, and your heart stops. You look at me wrong, your heart stops. From now on, you lose your right to refuse. You are nothing more but a puppet."

"What in hell are you-"

I moved a finger. The leader of the bullies-Tomas Gregory was his name-knelt down with a heavy thud. A horrible scream escaped his mouth as he began to quiver in pain.

I moved my finger again. Tomas's head slammed against the wet tiles, again and again. Blood seeped out of his skin, decorating the floor with splatters of red. The others looked at Tomas in absolute fear, frozen by the unbelievable sight before their very eyes.

"How…how could this be…!? This is, this is impossible!", one of the boys shrieked hysterically.

I inclined my head, an eyebrow raised.

"Oh my! Would you perhaps, want to demonstrate? To prove that this-"

I nudged my chin at the whimpering thing shivering on the floor.

"-Is all a dream?"

The boys turned impossibly white, frightened out of their wits. Some of them fainted before their bodies hit the ground, while others urinated on themselves. I felt my nose crinkle at the unpleasant smell.

"Clean this bathroom for me, will you?", I ordered. "Oh, and don't forget-"

I grinned at them, my teeth flashing white in the semi-darkness.

"-I'm always watching."

I turned and left, waving a lazy hand at them from my back.

"You are all dismissed until further orders. Do try to remember that failure shall result in your death."

I slumped against the wall once I was sure I was completely alone. Sweat poured from my forehead as my vision blurred. 'Physical depletion caused by Mana exhaustion.', I realized in my aching head.

No wonder I'm a failure. Only a few seconds of modification and control. Only a few seconds and I'm wasted. The tingling within my magic circuits was the testimony to that. Frail magus circuits that might overheat at any second. What a joke!

I limped out of the Clocktower after I changed my clothes, and headed home. Well, if you can call an empty quarter of the gigantic manor a home. My room was spacious enough, filled with books and devices needed for magical practice.

I was ready to leap into bed, until a voice stopped me.

"Hello, dearest brother of mine. I did tell you to come and visit me once you're home."

A young woman elegantly stood in the shadows, leaning against the wall with her arms crossed. She wore an expensive black evening dress made of fine fabric, completed with a blue rose pinned in her blond hair.

Her blue eyes danced playfully when she met mine, like a cat itching to play with her best chew-toy.

"Hello, Reines."

Before me, stood the next Lord of the Clocktower and prodigy of House El-Melloi. Reines El-Melloi Archisorte, my sister and my only family who genuinely cared about my wellbeing.

Reines flashed me a warm smile.

"Care to join me for supper, Dearest brother of mine?"

Aaaaaaaaaaaand wrap! Kinda short, but since this is a prologue it's kinda expected.

Pls drop a review if you are excited for more!

X-kalibuuuur, over and out!
