The Chaldea Library was a quiet haven filled with the scent of aged paper and ink, its towering shelves lined with knowledge from countless eras and realms. MoM hummed a cheerful, nonsensical tune as he trailed his gloved fingers along the spines of the books. His head swiveled back and forth like a curious bird, scanning for a specific kind of treasure.

"No carbon copy of the Book of Prophecies," he muttered to himself, pulling out a random book, inspecting it briefly, then sliding it back with an audible sigh. "What a shame. A library this expansive, yet it's missing the essentials."

Hans Christian Andersen, seated at a nearby table, adjusted his glasses and glanced over. "The 'essentials,' you say? That's quite the statement from someone who's just shown up and rifled through our collection like a child hunting for candy."

Across the table, William Shakespeare leaned forward with a grin. "Indeed! Pray, what 'essentials' does this enigmatic Moon Cancer seek? Stories of heroes? Tales of tragedy? Or perhaps," he smirked, "a tome of his own inscrutable musings?"

MoM chuckled, spinning to face the two authors with exaggerated theatricality. "Oh, my dear scribes of legend, don't flatter yourselves. I was merely hoping for something... profound. A narrative that pushes the boundaries of fate itself! A guide to weaving the threads of destiny into something new."

Ritsuka stood by Mash near the entrance, arms crossed. He sighed and leaned toward Mash. "They're expecting way too much from him, aren't they?"

Mash nodded slightly, whispering, "It's like watching three playwrights argue over a blank script."

MoM clapped his hands together suddenly. "Alas, I found no such book. And what I did find? Hmm." He turned a critical gaze toward Andersen and Shakespeare. "Let's just say... I expected more from two of history's most celebrated storytellers."

Andersen's eye twitched. "More?"

Shakespeare raised an eyebrow, his grin faltering. "How dare you, sir? My works have been praised for centuries!"

MoM raised a gloved hand, wagging a finger. "Ah, but longevity doesn't equate to perfection. Your tragedies lack a certain... unpredictability. And as for you, Andersen," he turned, causing the smaller Servant to bristle, "your tales could do with a little more flair. The endings are far too bittersweet. Where's the pizzazz? The spark of madness?"

Andersen snapped his book shut with a sharp thud. "Says the man who hums while pretending to look for books. Do you even read?"

Shakespeare chuckled nervously, though his pride was clearly wounded. "I'll have you know, my dear Moon Cancer, that my works are unparalleled in their craft! Perhaps you simply lack the intellect to appreciate them."

MoM laughed, twirling dramatically. "Oh, don't take it personally, gentlemen. I'm merely pointing out that your offerings are... quaint. I have a taste for the cosmic and chaotic, you see. Stories that rewrite the rules."

Andersen leaned back, arms crossed, grumbling. "This guy's more insufferable than a critic who hasn't read the book."

Shakespeare smirked, recovering his composure. "He may be eccentric, but I sense potential. A man who critiques destiny itself might yet write a tale worth telling."

MoM turned to Ritsuka and Mash with a flourish. "Well, Master of Chaldea, it seems your library fails to meet my impossibly high standards. Shall we move on before I bruise any more egos?"

Ritsuka groaned, running a hand through his hair. "You planned this, didn't you?"

MoM spread his arms wide, his voice dripping with mock innocence. "Planned? My dear Ritsuka, I merely follow my heart as my guiding key!"

Mash stifled a laugh as Ritsuka pinched the bridge of his nose. Andersen and Shakespeare watched the enigmatic Moon Cancer leave with a mix of irritation and reluctant curiosity.

"I hope we never cross paths again," Andersen muttered.

Shakespeare smirked, stroking his chin. "And yet... wouldn't he make for a fascinating protagonist?"

Andersen groaned. "You're hopeless."

As the group stepped out of the library, they were greeted by two smaller, yet no less intriguing figures—Nursery Rhyme and Jack the Ripper. The pair approached with wide, curious eyes, both intrigued by the new addition to Chaldea.

"Who's this?" Nursery Rhyme asked, tilting her head like a curious child. Her voice carried a playful tone. "You look like someone with lots of stories to tell!"

Jack tugged at Ritsuka's sleeve, her innocent expression masking her darker origins. "Mommy, what is this strange man talking about? Can I stab him?"

MoM gasped dramatically, placing a gloved hand over his chest. "Stab me? My, what sharp words for such a tiny killer! And did I hear correctly? You called Ritsuka 'Mommy'? Oh dear, oh dear—what an interesting revelation!" He leaned toward Ritsuka, his tone a mix of mock horror and curiosity. "Why didn't you tell me you were leading a double life as Chaldea's doting matriarch?"

Ritsuka's face turned crimson. "W-what?! That's not—Jack just calls me that! It doesn't mean anything!"

Mash struggled to suppress a giggle while Jack blinked up at Ritsuka, confused. "But you are my mommy," Jack said matter-of-factly, holding Ritsuka's hand tighter. "Right?"

Nursery Rhyme clapped her hands together with a bright smile. "Oh! Maybe he's like a mommy to everyone here? That makes sense!"

MoM rubbed his chin thoughtfully, his eyes twinkling with mischief. "Hmm, a nurturing figure in the heart of Chaldea, surrounded by an ever-growing family of eccentric individuals. Yes, yes, I can see it now—a parental figure guiding their unruly children toward salvation! It's all so poetic."

Ritsuka groaned, burying his face in his hands. "Stop making it weird!"

MoM waved a dismissive hand. "Weird? Why, I'm simply painting a narrative! Besides, I'm quite good with children, you know." He crouched to Nursery Rhyme and Jack's level, his hood casting an enigmatic shadow over his grin. "Now then, little ones, would you like to hear a story?"

Nursery Rhyme beamed. "Yes, please! Tell us something fun!"

MoM stood, adopting a storyteller's pose with one hand raised and the other behind his back. "Ah, let me think... Once upon a time, there was a mysterious scholar who ventured into lands unknown. He encountered countless strange and fascinating creatures, each more peculiar than the last. But one day, he met his match in the form of a little girl with a penchant for sharp objects!" He glanced at Jack with a playful grin. "Sound familiar?"

Jack tilted her head, her expression neutral. "That's not a real story," she stated bluntly.

"Ah, but isn't reality subjective?" MoM retorted, spinning on his heels. He launched into a convoluted ramble about multiverses, fated encounters, and the existential nature of storytelling. His voice filled the hallway like a chaotic symphony of cryptic musings.

Nursery Rhyme frowned, trying to follow along, but soon her eyes began to glaze over. "This doesn't make any sense…"

Jack pressed a hand to her temple, looking up at Ritsuka. "Mommy, what is he talking about?" Her innocent tone turned serious. "Can I stab him now?"

MoM gasped mockingly, feigning offense. "What barbaric tendencies! And to think I was about to tell you a secret story of the heart's guiding key! Truly, I am underappreciated."

Nursery Rhyme giggled at the theatrics, but Jack still looked unconvinced. Mash stepped forward, placing a reassuring hand on Ritsuka's shoulder. "Senpai, I think this is just how MoM operates. We should probably keep moving before he gives them an existential crisis."

Ritsuka sighed, patting Jack on the head. "No stabbing, okay? Let's just... humor him for now."
