The halls of Chaldea buzzed with activity as BB stormed through. Her heels clicked sharply against the floor as she muttered, "Unbelievable! A new Moon Cancer waltzes in, wreaking havoc, and I'm supposed to just let it slide? No way! There's only room for one chaotic genius in this place, and that's BB-chan!" Her first stop was Jeanne Alter, who was still simmering with anger from her previous encounter with the Master of Masters. BB approached with a confident smirk, placing a hand on her hip. "Hey, Jeanne... Alter," BB began, dragging out the pause with a mischievous glint in her eye. "You've got that 'I'm-angry-at-the-world' look on your face. Did a certain hooded Moon Cancer happen to cross your path?"

Jalter's eye twitched at the mention, and flames almost visibly flickered around her. "That idiot? Don't get me started on him! If you're looking for him, I'd suggest you drag him straight to the Throne of Heroes so I never have to deal with him again!"

BB chuckled, leaning closer. "Ooh, spicy. He must've really gotten under your skin. Do tell, what did he do?"

"He had the audacity to stare, hum, and spew nonsense!" Jalter snapped, crossing her arms with a huff. "And he insulted my adorableness by comparing me to my stupid chibi counterpart. The nerve!"

BB's grin widened as she placed a hand over her mouth in mock surprise. "So he's already ruffling feathers, huh? Sounds like my kind of guy—er, enemy. Don't worry, Jeanne, BB-chan will take care of him. Nobody messes with my territory."

Before Jalter could retort, BB was off to her next target, this time cornering EMIYA in the dining hall. He was busy chopping vegetables but sighed audibly the moment BB approached.

"Let me guess," he said flatly, not even looking up. "You're here about the Moon Cancer."

"Wow, Archer-kun, you're as sharp as your kitchen knives!" BB teased, leaning over the counter. "So, where is he?"

EMIYA paused, glanced at her, and returned to his chopping. "Last I saw, he was running for his life from an army of Chibi Nobus. He's probably hiding somewhere. Good luck."

BB pouted. "Aw, no juicy details? Come on, he's stealing my spotlight here! Aren't you mad about that?"

"Mad?" EMIYA raised an eyebrow. "No. Irritated? Sure. But mostly, I'm just tired of cleaning up after his antics. He's your problem now."

Unfazed, BB skipped off, questioning several other Servants, each with mixed responses ranging from amusement to annoyance. By the time she reached Mash and Ritsuka, her patience was wearing thin.

"Senpai~!" BB called sweetly, clasping her hands behind her back. "You wouldn't happen to know where your new little troublemaker is hiding, would you?"

Ritsuka blinked, clearly caught off guard. "Uh, Master of Masters? I haven't seen him since—"

"He's not your Moon Cancer, by the way," BB interjected sharply. "I don't care what he calls himself; this is my turf. You better find him and tell him that before I do."

Mash stepped forward. "BB, I'm sure there's room for both of you here in Chaldea. Can't we all just—"

"Absolutely not!" BB cut her off with a dramatic pose. "The Moon Cancer class belongs to BB-chan! No exceptions!"

As she stormed off in search of her rival, Mash turned to Ritsuka with a sigh. "I think we're in for a long day..."

Ritsuka nodded with a tired sigh. "You're telling me..."

The vending machine hummed softly as the Master of Masters stood before it, his hood tilted in curiosity. He tapped the machine's display, muttering to himself. "Fascinating... so you press buttons, and snacks or drinks just fall out. But 2,000 yen for a soda? That's robbery!"

Before he could debate further, BB's voice echoed through the hall.

"There you are, faker!" she bellowed, pointing dramatically at the hooded figure. "BB-chan has found you at last!"

The Master of Masters nearly jumped out of his boots, clutching his chest. "Great darkness, lady! Are you trying to give me a heart attack?"

"Spare me the theatrics, old man!" BB shot back, stepping closer menacingly. "You've been prancing around Chaldea acting like some big shot Moon Cancer, but there's only one Queen of Chaos here, and that's me! So, I'm challenging you to a fight!"

He raised his hands in mock surrender, backing away slightly. "Fight? Oh, no, no, no. You've got the wrong Moon Cancer. See, I'm not much of a fighter. I'm more of a... thinker. And a lover of snacks, apparently." He gestured to the vending machine.

BB narrowed her eyes. "Don't play coy with me! You're just messing with me, aren't you?"

"Messing with you? Perish the thought!" the Master of Masters said, feigning shock. "I'm just a humble observer of chaos, not a participant. Also, I've got this thing where I really don't like taking my coat off. It's very... drafty."

The growing crowd of curious Servants began murmuring among themselves, intrigued by the exchange. BB, however, was running out of patience.

"Enough of this nonsense!" she snapped. "If you won't fight willingly, I'll force you to!"

The Master of Masters sighed dramatically, shaking his head. "Fine, fine. If you insist, I suppose I'll defend my honor." He stepped forward, standing awkwardly in what could barely be considered a fighting stance. "But let me warn you... I have no idea what I'm doing."

The Servants watching facepalmed in unison. BB's eye twitched in irritation.

"Tch! You're really asking for it now!" she growled, summoning her Moon Cancer armaments.

The Master of Masters raised a hand, halting the imaginary tension in the air. "Wait! Before we begin, I just remembered something very important."

BB cocked an eyebrow. "What now?"

"I don't have my Keyblade," he said nonchalantly, scratching the back of his hood. "I lent it to one of my apprentices... oh, forever ago. Totally slipped my mind!"

There was a moment of stunned silence before BB and the surrounding Servants all collapsed anime-style.

"You've got to be kidding me!" BB shouted, glaring up at him from the ground.

The Master of Masters shrugged with a cheeky grin hidden beneath his hood. "Well, guess we'll have to postpone this duel, huh? Rain check, BB-chan! Let's do lunch sometime!" With that, he turned on his heel and strolled off, humming a merry tune as the gathered crowd erupted into mixed laughter and groans of disbelief.

BB, still fuming, slammed her fists into the floor. "He's mocking me! That coward is mocking me!"

Nearby, EMIYA crossed his arms with a smirk. "Looks like BB finally met her match—someone even more annoying than she is."

BB shot the smug Servant with a sharp glare. "Shut up, Archer!"
