The sterile atmosphere of the Chaldea control room was filled with a familiar, almost comfortable buzz—until it wasn't. The air grew tense as the eerie hum of a new summoning filled the space. Gudako Fujimura stood at the center of the circle, her orange hair slightly tousled from the sheer intensity of the summoning ritual. She grinned, always up for a new, chaotic addition to her already bizarre roster of Servants.

"Alright, come on, come on, what do we have this time?" she muttered to herself, eyes gleaming with excitement. Mash stood nearby, a mix of curiosity and concern written on her face.

The summoning circle glowed an ominous green, the lights flickering sporadically as if the very machinery of Chaldea wasn't sure what was about to materialize. The ground began to shake slightly, and suddenly, an unnatural hissing echoed through the room. A dark, sleek form began to emerge from the portal. Black, sinewy, and terrifyingly large, it crawled out of the circle, its elongated head gleaming under the flickering lights.

Gudako's grin widened even further as she clapped her hands together. "Oh, now this is going to be fun."

The creature fully emerged, towering over them with an otherworldly presence—a Xenomorph. The sleek, dark exoskeleton and terrifying posture screamed danger. Its spiny tail whipped the air with lethal precision, and its elongated skull tilted, eyeless, but clearly aware of the surroundings.

Mash, wide-eyed, took a step back, gripping her shield tightly. "Senpai… is that…?"

Gudako crossed her arms and gave the creature a once-over. "Oh, it's fine, Mash. It's just a big ol' space cat!"

Mash blinked in disbelief. "A… space cat?"

The Xenomorph hissed low, its mouth opening to reveal the second inner jaw, dripping with venomous saliva. Gudako, completely unfazed, crouched down slightly, clicking her tongue as if coaxing a cat out from under a couch. "Come on, who's a good alien monster thing? Who's a good little space kitty?"

The Xenomorph cocked its head, seemingly confused by the lack of fear from its new 'master.' Gudako, never one to show even an ounce of intimidation, walked up to the creature and scratched her chin thoughtfully. "Honestly, not what I expected when I hit the summon button, but we'll make it work."

Mash looked between Gudako and the Xenomorph, her face pale. "Senpai, are you sure that's safe? This creature looks incredibly dangerous!"

Gudako waved a hand dismissively. "Dangerous? Sure. But so was Berserker the first time we summoned him, and we survived that, didn't we?" She then reached out, much to Mash's horror, and tapped the Xenomorph lightly on its exoskeleton. "See? It's fine. It just needs a name!"

The Xenomorph's head tilted again, more curious than aggressive, and it lowered itself slightly, almost as if awaiting instructions. Gudako beamed triumphantly. "Look at that! It's already house-trained. We're totally keeping it."

Mash exhaled slowly, still gripping her shield but somewhat reassured by the Xenomorph's non-aggression. "So… what now?"

Gudako grinned even wider, clearly already envisioning all sorts of chaotic scenarios with her new summon. "Now? Now we train it! Space cat's going to be part of the Chaldea family. Maybe I'll summon it against some Servants. Let's see how long Gilgamesh's ego holds up when I throw this thing at him."

She crouched again, looking up at the Xenomorph's eyeless face. "First, though, we need to test you out in the field. Let's see if you can handle a few… guests."

Just then, an alarm blared, signaling the approach of enemy Servants. Gudako's grin grew, excitement flickering in her eyes. She turned to Mash and nodded. "Perfect timing. Let's give space cat a test run."

As they headed toward the battle zone, the Xenomorph slithered behind them, surprisingly agile for its size. Mash shot Gudako a nervous glance. "Are we really going to use that thing in combat?"

Gudako gave her a playful shrug. "Why not? Honestly, Mash, don't overthink it. It's a space cat." She winked. "We'll just have to be careful where it leaves its tail."

And with that, they marched into battle, with their newest summon—a sleek, terrifying Xenomorph—ready to prove itself as part of Chaldea's ever-growing family of oddities.
