In the past, there existed a mysterious ritual involving seven Masters and seven Servants.
A war where seven Masters and seven Servants engaged in fierce battles, all vying for the Holy Grail— a legendary artifact said to be capable of granting any wish.
This war was not just an ordinary battle. Each Master was paired with a Servant, a heroic spirit revived from legend and history. They fought as one, relying on strategy, strength, and wit to survive until only one remained victorious.
Each Servant was summoned into specific classes that reflected their skills and identity during their lifetime. Generally, there were seven main classes in this war:
Saber—Swordmasters renowned for their speed, technique, and balanced combat abilities.
Archer—Expert marksmen with extraordinary accuracy, capable of attacking enemies from long distances with arrows or other projectiles.
Lancer—Spear-wielding warriors known for their swift and deadly strikes, with a broad attack range.
Rider—Combatants with exceptional skills in riding or controlling legendary mounts.
Assassin—Stealthy killers who move in the shadows, relying on cunning and lethal attacks from darkness.
Caster—Mages with extensive knowledge of spells and high-level magic.
Berserker—Warriors who sacrifice their sanity for raw, overwhelming strength beyond human limits.
Each class had its own strengths and weaknesses, making the war not only a battle of power but also a contest of strategy and intellect.
To achieve victory, Masters and Servants had to fight, form alliances, and even betray one another.
Only one could emerge as the winner of this war.
And for those who failed, the only certainty was destruction.
This battle was known as... The Holy Grail War.

"Ah… this is really troublesome…"
I let out a long sigh, trying to ease the fatigue creeping into my body. Fujimaru and Mash were still staring at me—curiosity and wariness clearly visible in their eyes.
"So, you want to know why I can use a bow… and even handle it quite well, don't you?" I asked, though I already knew the answer.
They both nodded in unison.
I sighed, leaning slightly against the ship's railing. If I thought about it, a Rider wearing a naval commander's uniform but wielding a bow with the skill of an Archer… it did sound ridiculous. If I tried to make an excuse, it would only seem more suspicious. Besides, sooner or later, they were bound to find out the truth anyway.
"Where should I begin?" I muttered, crossing my arms. "Ah, right. How about I start by explaining how I can create weapons?"
Taking a deep breath, I closed my eyes for a moment before extending my hand forward. The air around me trembled as mana particles gathered, slowly forming something.
In an instant, a long sword appeared in my grasp, its blade glimmering faintly under the sunlight.
Fujimaru's eyes widened, and Mash looked visibly surprised.
"This is one of the abilities I possess," I said, raising the sword so they could see it clearly.
"In short, this ability allows me to create weapons or specific objects… including replicating sacred artifacts and armaments."
I swung the sword lightly in the air before adding,
"Though, of course, these replicas will never be as powerful as the originals."
Fujimaru observed the sword with fascination, then, as if struck by an idea, he asked eagerly, "Then… can you copy Mash's shield?"
I gave a small smile and nodded.
Closing my eyes briefly, I focused my thoughts, envisioning Mash's large and distinct black shield. The sword in my hand vibrated, its shape shifting, and within seconds, it had transformed into a round black shield—identical to the one Mash wielded.
Mash's eyes widened in astonishment as she looked at the replica of her shield.
"What do you think? Pretty cool, right?" I asked, lifting the shield with a hint of pride.
Fujimaru looked impressed, while Mash remained silent for a moment before finally speaking.
"But… how is that even possible? Even many Casters wouldn't have an ability like this…"
I simply smiled faintly, resisting the urge to reveal everything at once.
"Well, that's a long story," I replied nonchalantly. "But for now, just consider it one of my unique traits."
Mash still seemed deep in thought, while Fujimaru gave a small, amused smile.
"That was really unexpected," he said, looking at me with a more relaxed expression. "But at the very least, I'm glad to know we have an ally who can do something like this."
I chuckled. "Don't rely on me too much. I have my limits too."
Before the conversation could fully settle, the communicator suddenly buzzed again—this time, Roman's voice carried a more serious tone.
"I can understand how you can create weapons, but something doesn't add up. Aren't you supposed to be a Rider? How can a Rider have an ability like this?"
I chuckled lightly, finding Roman's confusion quite amusing.
"That's because… from the very beginning, I was actually a Caster," I answered casually.
Honestly, if my character profile hadn't been updated, I wouldn't have even known that I had a class.
(A: At first I wanted her to have no class, but then because I was interested in making her participate in the Holy Grail war, so then I make her have a class)
As soon as I spoke, silence filled the air.
But after a few seconds—
"What?!"
Roman's voice came through louder, as if he couldn't believe what he had just heard.
"Didn't you introduce yourself as a Rider? Don't tell me… you were lying to us…!"
I shrugged, still with a smile on my face.
"Isn't that normal?" I asked rhetorically. "Besides, I didn't know if I could trust you either when we first met."
Silence filled the air for a moment.
"That… makes sense," Roman finally admitted, sounding slightly reluctant to acknowledge the truth in my words.
Fujimaru seemed to be deep in thought before finally looking at me with curiosity.
"In that case, since you told us about this… does that mean you trust us?"
I stared at him briefly, then nodded slowly.
"Yes. That's right."
However, before I could continue and explain further—
SPLASH!
The loud sound of water splashing came from behind me.
I immediately turned around, my battle instincts kicking in as I reflexively raised the shield I was still holding.
BANG!
A powerful impact slammed against my shield, forcing me to stumble back several steps.
"Ugh—!" I gritted my teeth, trying to withstand the force of the attack.
When I straightened myself, I saw the figure now standing on the ship's deck—her body drenched, her long green hair dripping with water, and her emerald eyes glowing sharply under the sunlight.
Atalanta.
She slowly rose from her kneeling position after landing, shaking off her hair and tail with a graceful movement, resembling a wild cat that had just emerged from the water. Her gaze immediately locked onto me, her expression calculating… but there was a flicker of confusion in her eyes.
"Hm…? A child?" she muttered quietly, as if speaking to herself.
Her eyes then swept across the ship quickly, and I could see how they narrowed slightly upon seeing my crew—young girls now standing tensely around me, their expressions a mix of fear and caution.
The tension in the air remained as Atalanta and I stared at each other. Fujimaru, still shocked by Atalanta's sudden arrival, finally mustered the courage to speak, his voice wary yet filled with curiosity.
"Who are you? I saw you running across the water toward this ship, so I assume… you're a Servant?"
Atalanta didn't immediately respond. Her sharp eyes remained fixed on Fujimaru, analyzing every inch of his figure with an unreadable expression. Silence. Only the sound of the waves gently rolling against the ship filled the air.
Then, after a few moments, she finally spoke.
"You… are a human?" Her voice was flat, almost like a murmur. "It's rare to find a human in a place like this…"
Her gaze swept over us again, her eyes quickly assessing the situation. I noticed how her pupils narrowed slightly when she saw Fujimaru standing beside Mash.
"Seeing how you stand beside her, I assume she is your Servant and you are their Master?"
Fujimaru nodded slowly. He seemed to want to ask more questions, but before he could open his mouth, I spoke first.
"Isn't it rude to suddenly board someone else's ship without introducing yourself?" I said in a casual tone, though my intent was clear—I wanted her to state her identity.
Of course, I already knew who she was—Atalanta, the huntress from Greek mythology and a member of the Argonauts. But for now, I had to pretend I didn't recognize her.
Atalanta stared at me for a moment, her eyes seeming to analyze me more deeply, before she instead posed another question.
"How did you end up in a place like this…?" Her tone was more serious this time. "You shouldn't be in this era."
Fujimaru and Mash exchanged glances before Mash stepped forward slightly and began explaining their situation.
"We are from Chaldea, an organization tasked with maintaining the balance of human history," Mash spoke calmly, ensuring her words were clear.
"Right now, we are trying to repair a Singularity—a distortion in history that shouldn't exist."
Fujimaru continued, "We were sent here because this era has deviated from its proper course. Our mission is to find the cause and restore it to its original state."
Atalanta listened intently, her expression remaining unreadable. However, her eyes narrowed slightly upon hearing the words Singularity and Chaldea. She seemed to be processing the new information.
"Singularity? Chaldea?" she repeated the words softly, as if testing them on her tongue. "I don't understand those things…"
She then looked at us again, this time with sharper intensity. "But one thing is certain—you want to correct this distorted era?"
Fujimaru nodded firmly. "Yes."
I remained silent, but I quietly observed Atalanta's reaction. I didn't know if this would end in negotiation… or another battle.
The tension lingered as I watched Atalanta, waiting for her response. She seemed to be thinking, her expression still cautious but not showing outright hostility. A gentle sea breeze blew, making her green hair sway slightly as she shifted her gaze around the ship.
"I see…?" she murmured softly before looking at us again. "Then, what are your names?"
Her tone was not threatening, but there was a sharpness in her eyes that made me feel as if I were being scrutinized.
Fujimaru, sensing that this was an opportunity to ease the tension, took a slight step forward and introduced himself.
"I'm Fujimaru Ritsuka, and this is Mash, my Servant," he said, gesturing toward Mash, who stood firm beside him, still gripping her shield tightly.
Atalanta shifted her gaze to Mash briefly, then to me and my crew standing behind me, still in formation, alert but not openly aggressive.
Fujimaru continued, "And he…" he glanced at me with slight hesitation before continuing, "is the captain of this ship. He prefers to be called by his class name."
I smirked slightly and nodded. "That's right, just call me Caster."
Atalanta observed me for a longer time than the others, her eyes narrowing slightly.
"Caster, huh?"
Her tone carried a hint of skepticism, which I could understand. After all, a Caster wielding a bow and leading a ship full of young girls was hardly ordinary.
I then dismissed the replica of Mash's shield, sensing that Atalanta held no hostility. She raised an eyebrow as she watched me do it but said nothing.
She then turned her attention to my crew—the girls remained silent, but I could tell they were carefully watching Atalanta's every move, as if ready to act if necessary.
"And the girls?" Atalanta finally asked, nodding toward them.
I glanced at my crew briefly before answering. "They are my ship's crew."
I crossed my arms, looking at Atalanta casually. "They might not look like it, but they're pretty tough."
Atalanta didn't respond immediately, but her eyes scanned the girls one by one again. I saw something in her expression—not just wariness, but also curiosity.
Then, she let out a soft sigh. "I see. A captain and his crew… and a Master from Chaldea." She looked back at Fujimaru.
"I still don't fully understand your purpose, but if you're trying to restore this era… perhaps we have a reason to talk further."
Atalanta fell silent, her expression showing that she was struggling with her thoughts. Her emerald eyes stared sharply at the ship's deck, as if contemplating something important.
I remained silent, waiting for her decision.
A few moments later, she lifted her head and looked directly at me.
"Navigate this ship to the island I came from earlier," she said firmly. "There is someone I want you to meet, and I will explain everything… there."
Her request left everyone on board momentarily silent. I could sense the tension among my crew, who were still hesitant to trust Atalanta so easily.
Fujimaru looked surprised, then glanced at me as if asking for my opinion. Mash remained cautious, though I could tell she was also curious about what Atalanta meant.
I stared at her silently, trying to read her intentions. Though her request seemed suspicious, I sensed no deceit in her voice.
I rested a hand on my hip before asking in a casual tone, "And why should I trust you just like that, hm?"
Atalanta frowned slightly but didn't seem offended. "You don't have to trust me," she said. "But I'm sure you also want to know more about what's really happening here, don't you?"
I let out a slow breath. She had a good point.
"Alright," I finally said. "But if this is a trap, I won't sit idly by."
Atalanta didn't look afraid or offended—if anything, she simply stared at me with unwavering eyes.
"I wouldn't waste my time on such things," she replied before turning toward the ship's edge, standing there as if waiting.
I smirked slightly before turning toward the helm, gazing out at the vast ocean ahead.
"Alright then, let's see what we'll find there. Shall we?"

Author note:
I'm thinking about making a side story... What you're thinking about it?
Well, if you're has questions just ask..
About Mc class I think that's maybe Foreigner is more suited her because she's not originally from proper human history.
But because Foreigner is a forbidden class that was sealed, so I think it's was impossible to sneak her to holy grail war without Alaya noticed and so I make her to be Caster.
