what if, you're get summoned as a servant in Chaldea

Author: I want to inform you something, before you're start reading this chapter first i want you to know that Charles I is going alone with Mash and Ritsuka. Since I'm can't have a better idea about who should be Accompanying Charles.

Well then I'll let you know that the Time has skipped into 7 day since Ritsuka complete Singularity 4. Since in the game itself the singularity is Has a time lag to reappear and be searched.

So it's fine though to skip day right? Well tell me if you know something about when will a new singularity appear when we're complete the previous one.

I think It's still not the time to write a chapter about Singularity 5. Well, I'm still remembering how the Singularity 5 story went, but not completely. I will make a chapter about singularity 5 when I am completely sure about how the story will goes and when I'm remembering completely how the story of singularity 5 went in the game.

Sorry if I talk to much, I'm just wanted to say my opinion.

Well enjoy your reading time!

The cafeteria, Chaldea

The atmosphere cafeteria at Chaldea was abuzz with activity, the cacophony of clinking utensils, boisterous laughter, and lively chatter filling the air. Many Servants gathered for breakfast, creating an atmosphere of barely controlled chaos.

At one corner of the room, Achilles and Astolfo were arm-wrestling on a table that groaned under the strain.

"Come on, Achilles, I've got this!" Astolfo grinned, his pink hair swaying as he leaned all his weight into his effort.

Achilles smirked, barely exerting himself. "Sure you do, Astolfo. You've almost—oh wait, no, you don't." With a flick of his wrist, he slammed Astolfo's arm to the table.

"Ahh, no fair!" Astolfo pouted, rubbing his wrist. "You didn't even try!"

"you're should not skip strength training, Astolfo." Achilles teased, leaning back in his chair with a satisfied grin.

At a nearby table, Atalanta glared at the duo. "Can't you two keep it down? Some of us are trying to enjoy breakfast without watching a display of your immature antics."

Astolfo turned with a sheepish grin. "Sorry, Atalanta! Want to arm wrestle instead?"

Atalanta sighed deeply, muttering something about "unbearable children" as she took another bite of her bread.

At another table, Gilgamesh (Archer) and his younger counterpart, Gilgamesh (Child), were locked in their own debate.

"Why are you eating grapes with a fork?" the child Gilgamesh asked, pointing at the older version of himself. "You're making it unnecessarily complicated."

"Because," Gilgamesh (Archer) replied with a smirk, elegantly spearing another grape, "a king must maintain dignity, even at the breakfast table. Something you clearly lack."

Child Gilgamesh scowled. "Dignity is overrated. Food is food. Watch this!" He grabbed a handful of grapes and tossed them into his mouth, smirking triumphantly as he chewed.

"Disgraceful." Gilgamesh (Archer) muttered, turning his attention back to his plate.

Meanwhile in another table, Iskandar and his younger self, Alexander, were exchanging notes on leadership while devouring their meals.

"You have to inspire your men with grand speeches!" Iskandar declared, gesturing wildly with a piece of toast. "Victory is in the heart, not just the sword!"

Alexander nodded, his eyes wide with admiration. "But strategy is important too, isn't it? Lord El Melloi II says so!"

At the mention of his name, Zhuge Liang (Lord El-Melloi II), seated nearby, adjusted his glasses and sighed. "Strategy and morale are both important. Now, could you please lower your voice? I'm trying to think."

Iskandar laughed. "Think all you want, but in battle, the roar of your spirit is what matters most!"

In the midst of all this, Nero was putting on an impromptu concert near the counter.

"Ah, my Praetorian Guard! Behold the beauty of the Emperor's voice!" she sang, twirling dramatically.

Caligula, standing beside her, clapped enthusiastically. "Magnificent, Nero! Truly divine!"

Nearby, Emiya, standing behind the counter, observed the chaos with a sigh. He wiped his hands on a towel, shaking his head.

"Every morning it's like this…"

As if on cue, a plate flew across the room, narrowly missing his head.

"Careful with the food!" Emiya shouted, his patience wearing thin. "Do you know how hard it is to keep this place running?"

But the Servants were too engrossed in their antics to listen.

As the noise continued to rise, Mash entered the cafeteria with a nervous smile, accompanied by Ritsuka Fujimaru.

"Senior." Mash said hesitantly, "maybe we should come back later..."

Ritsuka sighed, surveying the scene of chaos. "No, Mash. This is exactly what I expect from Chaldea. Let's grab some food before it gets worse."

The duo stepped carefully through the cafeteria, dodging flying objects and shouting Servants, fully embracing another morning of organized chaos in Chaldea.

Charles Room. Chaldea

Charles I lay sprawled on his bed, staring at the ceiling. He had been trying to fall back asleep for what felt like hours, but the attempt was futile. Something about the quiet hum of Chaldea's systems and the faint echoes of footsteps outside the Room kept him restless.

Letting out a sigh, he rolled over and sat up. His silver-white hair was tousled from sleep, falling into his eyes as he swung his legs off the bed. With a groggy stretch, he stood up and shuffled toward the mirror near his bedside.

As he looked at his reflection, he frowned slightly. The image staring back at him was that of a pale-skinned boy with striking blue eyes, his long white hair cascading past his shoulders. It was a face too innocent, too youthful, and far removed from the image of the imposing monarch he imagined himself to be.

"Ugh... Still looks like a kid," he muttered under his breath, tugging at a strand of his hair. The youthful appearance was both a source of irritation and embarrassment for him. It was difficult to be taken seriously as a Servant when he looked like he'd wandered out of a children's fairytale.

Yet, as much as it annoyed him, Charles couldn't deny the surreal beauty of his form. His sharp features and piercing eyes carried an otherworldly elegance befitting a king. His hair, though troublesome, gleamed like spun silver under the dim dormitory lights.

"I mean... not bad, I guess," he mumbled, tilting his head slightly to examine his appearance. A faint smirk tugged at the corner of his lips.

It was strange, being a transmigrator—an outsider now inhabiting the body of a long-gone king. The contrast between his memories and his current reality always left him in a state of quiet amazement. He reached up, running a hand through his hair as he considered how far he'd come.

"But seriously, couldn't it have been an older version? A little more... dignified?" he said, his tone caught between annoyance and amusement.

Still, as much as he grumbled about his appearance, Charles knew it didn't matter in the end. His strength, intelligence, and cunning were what defined him—not how he looked.

Turning away from the mirror, he stretched his arms above his head and let out a yawn.

"Well, if I can't sleep, I might as well find something to do."

He glanced around the room, considering his options. "Maybe I should check on the others... or find something to eat." A mischievous grin crossed his face. "Or maybe cause a little chaos to keep things interesting."

With that, Charles threw on his coat, his long hair trailing behind him as he stepped out into the hallway, ready to see where the morning would take him.

In Corridor, Chaldea

Charles I wandered through the corridor, his steps slow and deliberate. His mind drifted through a tangle of thoughts—his place in Chaldea, the strange reality of being here, and the secrets he already knew thanks to his prior knowledge of the story.

However, his musings were interrupted when he sensed another presence approaching. He glanced up and saw none other than Dr. Roman, walking a few steps ahead.

Roman appeared lost in his own thoughts, his pace unhurried and his expression distant. To anyone else, he might seem like the ever-distracted head of Chaldea. But to Charles, he was something much more—a man carrying the weight of an enormous secret.

'Solomon....' Charles thought to himself, a knowing smirk tugging at his lips. The grand reveal of Roman's true identity as the King of Magus from the game lingered vividly in his mind. It was surreal to see him like this, so unassuming, so... human.

Deciding to break the silence, Charles called out cheerfully, "Good morning, Doctor!"

His voice rang through the corridor, clear and sharp. Roman, startled, stopped mid-step and turned toward the source of the greeting. His expression softened when his gaze fell on Charles, a faint, tired smile gracing his face.

"Ah, Charles," Roman said warmly. "Good morning too. You're up early."

Charles chuckled, stepping closer. "Couldn't sleep. Too many things on my mind." His blue eyes glinted with mischief as he tilted his head. "What about you, Doctor? You look like you're carrying the weight of the world on your shoulders."

Roman let out a soft laugh, shaking his head. "You could say that. Though it's nothing unusual." His smile grew more genuine, though a trace of that hidden melancholy lingered in his eyes. "You've been settling into Chaldea well, I hope?"

Charles shrugged, his demeanor casual but his thoughts sharp. "It's an interesting place. Full of surprises. I can't say I've been bored."

Roman nodded thoughtfully. "That's good to hear. Chaldea can be overwhelming for newcomers, but it's also a place where bonds grow stronger. Everyone has a role to play."

Hearing this, Charles studied Roman for a moment, his smirk fading into something more subdued. There was a deep irony in hearing those words from a man who had willingly given up his throne and power for the sake of humanity.

"You're... an interesting person, Doctor," Charles said suddenly, his tone quieter now.

Roman blinked, a hint of confusion flickering across his face. "Oh? How so?"

Charles smiled, though it didn't quite reach his eyes. "You seem so ordinary, yet I feel like you're carrying something extraordinary. Like there's more to you than meets the eye."

Roman chuckled softly, though there was an edge of nervousness in it. "I think you're giving me too much credit. I'm just a doctor doing my best to support everyone."

"Hmm," Charles hummed, his gaze lingering on Roman a moment longer. "If you say so."

The two walked side by side for a while in silence, the quiet hum of Chaldea's systems filling the air. Charles tucked his hands into his coat pockets, as he glanced at Roman.

"Well, Doctor, I won't keep you. I'm sure you have important things to attend to." Charles said eventually, his tone light.

Roman nodded, his faint smile returning. "Take care, Charles. And don't hesitate to come by if you need anything."

As Roman continued down the corridor, Charles watched him go, his smirk returning.

"You really are something else, Doctor." he muttered under his breath.

With a shake of his head, Charles resumed his walk.

At cafeteria, Chaldea

It was already late in the morning, and the chaos of breakfast had passed. The cafeteria had grown quieter as most of the servants had already finished their meals and scattered to their respective duties. A few remained, finishing their food at a relaxed pace.

Charles I entered the cafeteria, his stomach grumbling, reminding him of the hunger he had pushed aside while lost in thought earlier. He spotted the counter where Emiya, now calmer and less rushed, stood cleaning up and preparing the last of the breakfast servings.

"Morning, Charles. Look like you're late as usual," Emiya remarked with a dry smile as Charles walked up to the counter.

"Mm." Charles responded with a tired grunt, not having the energy for any playful banter this time. His mind still carried the weight of the conversation he had with Roman. All he wanted now was to eat.

"Very well, as usual, I presume?" Emiya asked, eyeing Charles as he prepared his meal.

Charles simply nodded, confirming the usual choice without further discussion.

Charles then scanning the room for a place to sit. He spotted Jeanne d'Arc sitting alone, eating her breakfast quietly, her usual calm demeanor present.

Charles tilted his head for a moment, deciding to sit beside her. As he pulled out the chair and sat down, Jeanne looked up from her plate, her gaze meeting his.

"Good morning, Charles." she greeted, her tone light and warm, a faint smile tugging at the corners of her lips. She seemed used to his delayed appearances by now.

Charles, however, didn't feel like engaging in the usual playful exchange. His tiredness weighed down on him, and he only offered a silent nod in response. Jeanne raised an eyebrow, sensing something was off.

"You're rather quiet today... what happened?" she asked, her curiosity piqued.

"Just a bit tired..." Charles replied, his voice low as he glanced over at Emiya, who was finished preparing his breakfast and handed it to Charles, who silently took the tray.

"Enjoy your breakfast." Emiya said before walking away returning to his counter.

Charles didn't waste a moment. He dug into his meal, the hunger in him too strong to ignore. He ate quickly, savoring the comfort of a good meal, his tiredness momentarily forgotten as he focused on the food before him.

Jeanne watched him for a moment, amused by his eager consumption, before returning to her own breakfast. A quiet chuckle escaped her lips as she shook her head, finding comfort in the peaceful atmosphere of the moment.

After finishing his meal, Charles I leaned back in his chair for a moment, feeling the fullness of the breakfast settle in his stomach. The brief respite from the chaos had calmed his mind slightly, but the restless curiosity still lingered in his thoughts. He found himself wondering if it would be a good time to experiment with his Noble Phantasm again.

He stood up from his seat, giving a quiet nod to Jeanne as he made his way to the exit of the cafeteria. "Goodbye, Jeanne." he murmured, his voice barely more than a whisper as he left. Jeanne acknowledged him with a small, understanding smile, watching him leave with her usual calm.

Charles walked through the quiet halls of Chaldea, his footsteps echoing softly against the walls. He wasn't in the mood for conversation, and his mind was set on his experiment.

Battle simulation, Chaldea

The battle simulation room, usually configured to suit the needs of any combat training, was now an open expanse of blue flowers, their soft glow illuminating the area with an ethereal light. Charles I stood at the center of the simulation, his arms crossed as he contemplated his next move. Beside him stood Child Gilgamesh, his presence as calm and enigmatic as ever.

The young King of Heroes observed Charles with a curious glint in his crimson eyes, a small, knowing smile playing on his lips.

"So, you want to experiment with imitating other Noble Phantasms again, don't you, Carlie?" Gilgamesh teased, his tone light but tinged with interest.

Charles turned to face him, tilting his head slightly at the nickname but choosing to let it slide. "Right. Goldie, I want to see how far I can push this. Mimicking another Noble Phantasm isn't easy, but I've been making progress." He sighed, the weight of the task clear in his voice.

"Aha!" Gilgamesh exclaimed, his grin widening as he leaned forward, his eyes sparkling with curiosity. "Then tell me, what Noble Phantasm are you planning to imitate now?"

Charles glanced at him, a hint of confusion crossing his face. He had noticed how often Child Gilgamesh seemed to follow him around lately, always watching him with quiet fascination. Despite his initial reservations, he found himself growing used to the younger King of Heroes' company.

"You really enjoy tagging along, don't you?" Charles muttered, scratching the back of his head as he stared at the simulation field.

"Naturally," Gilgamesh replied with a soft laugh. "Observing others is one of my hobbies, and you, Carlie, are particularly interesting. A king with such an unusual Noble Phantasm, and one who seeks to mimic the abilities of others… How could I not be intrigued?"

Charles sighed, shaking his head with a small smirk. "Alright, Goldie. Since you're so curious, I'll show you. For this attempt, I'm going to try and replicate Jeanne d'Arc's Luminosité Eternelle. Her banner of protection and guidance—it's not purely offensive, but it's something I want to master."

Gilgamesh's eyes widened slightly, impressed. "Ah, a defensive Noble Phantasm meant to inspire and protect allies. I see your reasoning. But can you truly mimic such divine energy? I wonder..."

Charles took a deep breath, he extending his hand as he said his noble phantasm name softly.

"The valor of conquest."

the air around him shimmered. Blue and gold light began to swirl, forming the rough outline of a flagpole. It wavered slightly, unstable, before solidifying into a replica of Jeanne's banner. The energy it radiated was weaker than the original, but its presence was unmistakable.

"There," Charles said, exhaling deeply as he steadied himself. "It's not perfect, but it's a start."

Gilgamesh stepped closer, inspecting the banner with a critical eye. "Not bad, Carlie. It lacks the divine radiance of the original, but the form and intent are there. Your mimicry skills are improving."

"Thanks," Charles replied, a small smile creeping onto his face. "But this is just the beginning. I need to refine it further if I want to use it effectively in battle."

Gilgamesh nodded, his expression thoughtful. "Indeed. But do not overextend yourself, Carlie. Even the most ambitious kings must know their limits. That said, I look forward to seeing how far you can go."

Charles chuckled softly, glancing at Gilgamesh.

The atmosphere is lively even though it's just the two of them.

Author: well I'm just wanted to let you know that I wanted to improve Charles I mastered over his noble phantasm.

And about Charles nickname, well I'm just like to call him like that, well everyone else is calling him Charles but some of his best friend or close friends call him Carlie.

I know if this nickname should be king Charlemagne/Charles the Great had but since they're have a same name so it's fine though to call Charles I as Carlie.

Well I'm considering about add Charlemagne into Chaldea but I'm not sure about this though.

Btw about the conversation in the early chapter, Actually I want to add a lot of conversation and introduce the servants that has summoned in Chaldea in this fanfic but I think I want to focus more on developing Charles I mastery over his Np first.

I will eventually try revealed most of the servant that has summoned into Chaldea, When the story goes on.

Well The next chapter should be an a part 2 experiment with Charles' noble phantasm.

I want to take a nap before making new chapter...
