It was another day in Chaldea, and Ash and Pikachu were taking a casual stroll through the facility. After everything that had happened recently—from learning about Servants to dealing with Cú's antics and Gilgamesh's pranks—Ash was finally starting to get used to this strange new life. Sort of.

"I wonder what kind of crazy thing we're gonna run into today, buddy," Ash muttered, glancing at Pikachu.

"Pika-pi," Pikachu responded with a shrug. The Pokémon seemed just as wary of surprises as his Trainer.

As they turned a corner, a powerful yet cheerful voice boomed through the hallway. "Ah! So this is the new Master everyone's talking about! Ash, right?"

Ash looked up and froze in place, his jaw dropping. Standing before him was an incredibly tall, athletic woman with tanned skin, long golden hair tied with ribbons, and a radiant smile that exuded pure joy and energy. She wore a vibrant, colorful outfit reminiscent of ancient Mesoamerican culture, complete with feathered accents and a shining sun emblem on her chest.

The sheer presence of the woman was overwhelming, but it wasn't intimidating—it was warm and inviting, almost like a sunny day. Pikachu blinked, equally stunned, as the woman stepped closer with an excited bounce in her step.

"You must be the new Master! And who's this adorable little guy?" she exclaimed, crouching slightly to get a closer look at the two of them. Her eyes sparkled as she clasped her hands together. "Oh my goodness, you're both so cute! It's like meeting a pair of little brothers!"

Ash, still staring, managed to stammer out, "Uh, yeah, I'm Ash... and this is Pikachu. Uh, who are you?"

The woman's expression lit up even more (if that were possible), and she struck a dramatic pose, placing a hand on her hip and pointing to herself with her other hand. "I am Quetzalcoatl, the great Feathered Serpent of Mesoamerican legend! Rider-class Servant at your service! But you can just call me Quetz! Nice to meet you, Master Ash!"

Before Ash could say anything else, Quetzalcoatl reached out and ruffled his hair affectionately, laughing as Pikachu let out a small squeak of surprise. "You're even cuter in person than I expected! Look at this boyish charm! So innocent and full of potential! Ah, it makes me want to spoil you rotten!"

Ash's face turned bright red, and he waved his hands in protest. "H-Hey, I'm not that young! I've been on all kinds of adventures! I'm a Pokémon Trainer, you know!"

"Really?" Quetzalcoatl asked, her interest clearly piqued. She crouched to get closer to Ash's level, her intense gaze locking onto his. "That's amazing! No wonder you've got such a strong, determined look in your eyes. You're like a little hero in the making!" She giggled. "But don't get too ahead of yourself, pequeño—I think you could use a bit of training. You know, to build some muscles!"

Ash blinked. "Muscles?"

Quetzalcoatl gave a hearty laugh and flexed her own biceps, which were impressively defined. "Of course! A strong body leads to a strong spirit! And a strong spirit makes a great Master! You've got a lot of potential, Ash, but you're a bit on the skinny side. Let me help you bulk up a little, okay?"

Ash sweatdropped, glancing at Pikachu, who tilted his head in confusion. "Uh, I'm not sure that's really necessary. I mean, I'm more about strategy than strength..."

"Nonsense!" Quetzalcoatl declared, grabbing Ash by the shoulders. Her grip was firm but gentle, and her enthusiasm was contagious. "You can have both! Strategy and strength! Trust me, little hermano—I'll make sure you're the strongest, cutest Master in all of Chaldea! You'll be unstoppable!"

Ash's face turned even redder, and he waved his hands again. "I-I appreciate the offer, really, but—"

Before he could finish, Quetzalcoatl scooped him up in a playful hug, lifting him off the ground like he weighed nothing. "Oh, don't be shy! We're going to have so much fun! First, I'll teach you some basic exercises, and then we'll move on to advanced techniques. And after that, we'll celebrate with tacos and dancing! Doesn't that sound amazing?"

Pikachu stared up at the scene in disbelief, his ears twitching. "Pika...?"

Ash, still flustered and dangling in Quetzalcoatl's embrace, sighed in defeat. "Why do I feel like my life just got a whole lot crazier?"

Quetzalcoatl laughed, finally setting him down but keeping her hands on his shoulders as she beamed at him. "Because it did! But don't worry, hermano—I've got your back! From now on, think of me as your big sister. I'll take care of you!"

Despite his embarrassment, Ash couldn't help but smile a little. There was something undeniably comforting about Quetzalcoatl's presence, even if she was a bit overwhelming. "Thanks... big sis, I guess."

Quetzalcoatl's grin widened. "That's the spirit! Now, let's get started! Push-ups first!"

As Quetzalcoatl led Ash and Pikachu toward the training area, her laughter echoing through the halls, Mash watched from a distance, smiling softly. "Senpai really does attract all kinds of people... or, in this case, Servants."

The day had been nothing short of grueling for Ash and Pikachu. Quetzalcoatl, with her endless enthusiasm and boundless energy, had pushed them through what felt like an Olympian-level training regimen. By the time she finally declared their session over, Ash and Pikachu were both drenched in sweat and utterly exhausted, barely able to muster the strength to trudge back to Ash's room.

Ash stumbled into his quarters, flopping onto his bed face-first with a groan. Pikachu, equally spent, climbed onto the bed and collapsed beside him, his tiny body heaving as he panted.

"That... was insane," Ash muttered into his pillow, his voice muffled. "I didn't think anyone could have that much energy."

"Pika...chu..." Pikachu agreed weakly, his ears drooping.

Ash rolled onto his back, staring at the ceiling as he caught his breath. His arms felt like jelly, his legs felt like they'd run a marathon, and his entire body ached in places he didn't even know existed. Quetzalcoatl's training was no joke—there had been push-ups, sit-ups, squats, sprints, and even a bizarre wrestling match with her that had left Ash completely humiliated (though she'd cheered him on the whole time).

As he lay there, his thoughts drifted back to Quetzalcoatl's cheerful smile and encouraging words. She'd been relentless, sure, but she'd also been incredibly supportive, constantly cheering him on and reminding him of his potential. It was a different kind of training than what he was used to, but it had reminded him of his days traveling with his Pokémon—of pushing through tough battles and growing stronger together.

The door creaked open, and Quetzalcoatl peeked her head in, her face lighting up when she saw Ash. "Ah, there you are, pequeño! How are you feeling? Tired? Sore? Invigorated?"

Ash gave her a weak thumbs-up. "All of the above..."

Quetzalcoatl laughed heartily, stepping inside with a plate of food in her hands. "Good! That means it was a great workout! And look—I brought you some snacks! You'll need to refuel after all that hard work."

Ash's stomach growled at the sight of the food, reminding him that he hadn't eaten much during the day. "Uh, thanks," he said, taking the plate from her. It was piled high with colorful, delicious-looking tacos, and the smell alone made his exhaustion fade slightly.

"You did great today, hermano," Quetzalcoatl said, ruffling his hair affectionately. "I'm proud of you! Keep this up, and you'll be the strongest Master in no time."

Ash's cheeks turned a little pink, but he smiled despite himself. "Thanks, big sis. I'll do my best."

"That's the spirit!" Quetzalcoatl declared. "Rest up, okay? Tomorrow's another big day!"

Ash and Pikachu exchanged a horrified glance. "W-W-Whaaaaaaaaaaaat?!"
