The air in Chaldea's summoning chamber buzzed with tension as Ritsuka Fujimaru focused on the glowing circle before him. The command seals on his hand thrummed with power, and the anticipation of summoning a new Servant filled the room. "I hope this works," he muttered to himself, his heart racing. Each summoning was a risk, but the stakes had never felt higher.

With a surge of energy, the summoning circle erupted in a flash of light. Ritsuka shielded his eyes, heart pounding, as a figure materialized within the glow. As the light faded, a tall, striking girl emerged, her wild dark hair framing an assertive face, eyes sparkling with intensity. She wore a modified school uniform, complete with a flowing skirt that hinted at her martial prowess.

"Momoyo Kawakami?" Ritsuka breathed, momentarily stunned. He wasn't prepared for this—her fierce reputation as a fighter was legendary, but he had never anticipated her being summoned as a Berserker.

Momoyo crossed her arms, a scowl on her face. "What's the meaning of this? You're not Yamato!" She eyed Ritsuka with disdain. "I refuse to serve some random kid when my heart belongs to another!"

Ritsuka rubbed the back of his neck, taken aback by her outright rejection. "I—uh, well, it's not like I can control who gets summoned. You were called here for a reason. We need your strength to fight against the Threats to Humanity!"

"Yeah, and who cares about that?" Momoyo snapped, unfazed. "If I'm not fighting alongside Yamato, I have no interest in your little organization."

"Wait, wait," Ritsuka said, raising his hands. "Maybe you could just—"

Before he could finish, the room trembled as Quetzalcoatl, another Servant who had become a close ally, stepped forward, her presence radiant and powerful. "What's this? A new Berserker?" She beamed at Momoyo, her excitement palpable. "How about a friendly spar? I promise, it'll be fun!"

Momoyo's expression shifted from annoyance to curiosity. "A sparring match? With you?"

"Absolutely!" Quetzalcoatl grinned, her golden wings unfurling slightly. "Let's see what you've got! If you can handle it, maybe you'll reconsider your attitude toward this whole 'serving Chaldea' thing."

Ritsuka watched, a glimmer of hope sparking within him. If a friendly spar could change Momoyo's mind, it was worth a shot. "Okay, let's set it up!" He gestured toward the training arena, eager to witness the clash of these two formidable fighters.

As they entered the arena, the atmosphere shifted. Quetzalcoatl took a fighting stance, her confidence radiating from her. Momoyo, however, didn't back down; her eyes glinted with a fierce determination. "Fine. But don't hold back. I want to see what a goddess can really do!"

With a nod, Quetzalcoatl launched forward, the ground trembling beneath her feet. "Here I come!"

Momoyo sidestepped with agility, her instincts sharp. She countered with a flurry of punches, each strike precise and powerful. "You think you can just overwhelm me with speed? I'll show you!"

Quetzalcoatl grinned, dodging effortlessly. "Not bad! But can you handle this?" She spun mid-air, channeling energy into her wings, launching a series of golden feathers toward Momoyo.

The Berserker leaped high, using the momentum to deflect the feathers with a swift kick, her laughter echoing in the arena. "Is that all you've got? Let me show you true strength!"

Ritsuka watched in awe as the two exchanged blows, the power and ferocity of their combat mesmerizing. Momoyo's competitive spirit was infectious, her fierce determination igniting the air around them. Each strike echoed with the potential of their abilities, and he realized how lucky they were to have someone like her on their side.

"Come on, Kawakami!" Quetzalcoatl shouted, landing gracefully. "Show me your Berserker spirit!"

Fueled by Quetzalcoatl's encouragement, Momoyo's expression transformed into one of sheer exhilaration. "Alright then! Let's turn up the heat!" With a roar, she unleashed a flurry of rapid attacks, combining her martial skills with an almost reckless abandon.

Ritsuka felt a surge of pride. "That's it, Momoyo! You're doing great!"

As the match progressed, it became clear that Momoyo was relishing the fight. Her earlier reluctance began to fade, replaced by the thrill of battle. With each clash, she felt the weight of her past dissolve, replaced by the promise of new challenges.

Quetzalcoatl landed a kick that sent Momoyo tumbling back, but the girl quickly regained her footing, laughter bubbling from her lips. "Not bad for a goddess! You might just make me enjoy this after all!"

Breathless and grinning, Quetzalcoatl nodded. "I knew you had it in you! Welcome to Chaldea, Momoyo!"

With that, the final strike resonated in the arena, the two warriors standing side by side, exhilarated from their bout. Ritsuka approached, smiling broadly. "So, what do you think? Ready to fight for Chaldea?"

Momoyo's fierce demeanor softened slightly as she surveyed her surroundings. "Maybe… this isn't so bad after all." Her eyes glimmered with the thrill of battle and the prospect of new friendships. "As long as I get to keep fighting, I can see the appeal."

"Great!" Ritsuka grinned, relief flooding through him. "We're happy to have you here, Momoyo!"

"Just remember," she said, a playful smirk on her lips, "I'm not doing this for you. I want to find worthy opponents. And maybe, just maybe, if Yamato were here…"

Ritsuka chuckled, feeling the warmth of camaraderie grow. "We'll make sure you get plenty of fights. Welcome to Chaldea, Momoyo!"
