[Since you two want to compete in luck, I've prepared a compendium of Heroic Spirit Summon Rarity. Here, take it. No need to thank me.]
The system suddenly spoke up.
A radiant glow condensed out of thin air, transforming into a book that fell into Dracula's hand. He opened it and flipped through the pages, discovering that it meticulously documented the rarity of all Heroic Spirits—ranked by stars, with one-star being the most common and five-star the rarest.
As he leafed through it curiously, Dracula asked, "Where'd you get this thing?"
[While analyzing the data of this world—since, after all, I too must grow and evolve—I happened to overhear your little proposal. So I compiled this book. It ranks all Heroic Spirits in this world and across countless parallel timelines based on the number of times they've been summoned. The rarer the spirit, the fewer the summons.]
Explained the system.
"At long last, you've done something useful." Dracula nodded in rare approval.
At that moment, Kirie stepped forward. "Dracula-sama, I've finished memorizing the incantation. Shall we begin?"
"Alright!" Dracula was surprisingly excited about this game-like development. He stuffed the book into Jeanne's hands and said, "Here, Jeanne, you be our judge."
Jeanne took the book with growing interest and nodded. "Very well, Dracula-sama."
With high hopes, Dracula rolled up his sleeves and stood by the Heroic Spirit summoning circle. Stretching out one hand, he used his formidable magical power to forcibly connect with the Throne of Heroes.
He could feel it—a distant presence responding to his call, descending to his side from the Throne.
The summoning circle glowed blue. Then, emerging from the light… came a shining bald head.
"Ah, that complexion… that baldness—it's Darius III, a three-star Servant!" Jeanne exclaimed excitedly before the man had even fully emerged. "Looks like Dracula-sama's luck is quite underwhelming… This one's just a three-star—"
Boom!!
Before she could finish her sentence, Dracula stepped forward and stomped hard on the bald head, forcefully shoving it back into the circle.
Both Jeanne and Kirie stared at him in stunned silence.
Dracula clapped his hands nonchalantly, completely shameless. "Bit of a malfunction in the summoning array. That guy was a wraith, not a Heroic Spirit. Kirie, your turn."
"…Alright, but Dracula-sama, cheating is allowed only once," Kirie said, exchanging glances with Jeanne before stepping up to the circle.
She closed her eyes. A magical glow shimmered around her, and her twin-tails lifted slightly in the rising energy—giving her a distinctly divine aura.
Then, slowly, she began to chant:
"Fill, fill, fill, fill, fill.
Let each be turned over fivefold.
But when filled, be discarded.
Heed this proclamation—
Thy flesh shall be under my command; my fate shall be with thy blade.
Respond to the summons of the Holy Grail. If thou wilt follow this will and this reason, then answer me.
I hereby swear—
I shall accomplish all acts of good in the world.
I shall punish all acts of evil in the world.
Thou art clad in the three great words of power, bound by the seven heavens—
Come forth, guardian of balance, from the wheel of restraint—!"
As her final words rang out, a brilliant blue light once again flared from the circle.
A silhouette slowly rose. Clad in heavy metal armor, its face hidden beneath a horned helmet—
"Servant, Saber. Mordred. I come in response to your summons."
"That helmet…?" Jeanne flipped through the book, eyes lighting up. "That's a five-star Servant! Congratulations, Miss Kirie. Seems your luck is truly outstanding."
Kirie smiled and turned her head toward Dracula—who now stood off to the side, visibly deflated.
But before the joy could settle, things took a sudden turn.
Mordred's gaze locked onto Jeanne, who stood quietly off to the side, smiling. With a burst of rage, Mordred roared and drew her sword, charging straight at Jeanne.
"Arthurrrr!!!"
Jeanne barely dodged the blow and cried out, "Mordred! You've got the wrong person—I'm not your father!!"
"I don't care!! Die, Arthur!!"
Mordred went wild, swinging her royal blade with unrelenting fury. Jeanne had no choice but to manifest her spiritual armor and engage her in combat.
"Dracula-sama, do something!!" Kirie cried out.
But Dracula, still sulking, sighed deeply. "Kirie… are you showing off right now? You summon a five-star like Mordred, and now you're flaunting it?"
He shook his head, waving his hand. "Sorry, Kirie. Looks like you and I… we were never meant to be friends in this life."
Seeing him so despondent, Kirie ran up and kicked him square in the shin, shouting, "Dracula-sama, stop moping and break them up! Besides, you haven't even drawn yet!"
"…Oh, right." Dracula snapped out of it and with a quick flash step, appeared between Jeanne and Mordred. He reached out and grabbed both Jeanne's flag and Mordred's sword, blocking the fight.
"Alright, enough. Just a misunderstanding. Let's all calm down."
Jeanne immediately backed off. Mordred, however, kept struggling.
"She's lying! She is Arthur!"
Dracula leaned in close, tapping his finger against his temple.
"Use your head, young lady. Would King Arthur have a chest that big?"
"Dracula-sama! That's sexual harassment!!" Jeanne blushed furiously and crossed her arms over her chest.
Mordred froze. She glanced at Jeanne's chest… and awkwardly sheathed her sword.
"…Sorry. I made a mistake."
"Ah, it's alright. I forgive you," Jeanne said, face still flushed.
"You people from Camelot seriously judge identity by breast size, huh…" Dracula mused, stroking his chin. "How very… English of you."
"Alright! Now that the misunderstanding is cleared up, it's time for my summoning round!" With a grand flourish, Dracula returned to the summoning circle. "Come forth—my five-star destined Heroic Spirit!"
Mordred, still processing everything, stared at the glowing circle.
"…That's really how I was summoned?"
"Not quite." Kirie gently took her hand. "I made sure to recite every word of the incantation properly."
The circle lit up again. From within it stepped a girl with long green hair, two small dragon-like horns, and a graceful moon-white kimono—a striking beauty.
"Congratulations, Dracula-sama," Jeanne said as she checked the book. "Although Kiyohime is only a three-star Servant, at least she's a cute girl. That's a huge improvement over Darius."
This French holy maiden was surprisingly skilled at dealing out calm, devastating burns.
The girl walked up to Dracula, staring at his face with infatuated eyes.
"I have answered your summons. I am the Berserker-class Servant, Kiyohime. Are you the Master who will be with me for all eternity? Ah… such a handsome Master you are."
