The sterile atmosphere of the Chaldea control room was filled with its usual, comfortable hum—until it wasn't. The air grew thick with tension as the eerie sound of a summoning ritual filled the space. Gudako Fujimura stood at the center of the summoning circle, her orange hair slightly tousled from the intensity of the ritual. A wide grin stretched across her face, the thrill of another chaotic addition to her bizarre roster of Servants lighting up her eyes.

"Alright, come on, come on, what do we have this time?" she muttered, excitement gleaming in her gaze.

Mash stood nearby, her expression a mix of curiosity and concern as she watched the summoning unfold.

The summoning circle glowed an ominous green, and the lights in the room flickered as though Chaldea itself was uncertain about what was about to materialize. The ground began to tremble, and an unnatural hissing sound echoed through the control room. Slowly, a dark, sleek form began to emerge from the portal—black, sinewy, and terrifyingly large. It crawled out, its elongated head gleaming under the sporadic flickering lights.

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

The creature fully emerged, towering over them with an otherworldly presence—a Xenomorph, Assassin Class. Its sleek, dark exoskeleton, spiny tail whipping through the air, and eyeless, elongated skull radiated lethal danger.

Mash's eyes went wide as she took a step back, gripping her shield tightly. "Senpai… is that…?"

Gudako waved off her concern, arms crossed casually as she looked the Xenomorph up and down. "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 inner jaw, dripping with venomous saliva. Yet, Gudako remained completely unfazed. She crouched slightly, clicking her tongue as if coaxing a stray animal. "Come on, who's a good alien monster thing? Who's a good little space kitty?"

The Xenomorph cocked its head, seemingly confused by Gudako's lack of fear. In typical fashion, she sauntered right up to the towering 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, still pale with worry. "Senpai, are you sure that's safe? This creature looks incredibly dangerous!"

Gudako waved a dismissive hand. "Dangerous? Sure. But so was Berserker when we summoned him, and we survived that, didn't we?" Without hesitation, she tapped the Xenomorph lightly on its exoskeleton. "See? It's fine. It just needs a name!"

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

Mash exhaled slowly, still gripping her shield but slightly reassured by the creature's surprisingly calm demeanor. "So… what now?"

Gudako's grin turned devilish, her mind clearly already racing with ideas. "Now? Now we train it! Space cat's part of the Chaldea family now. Let's see how long Gilgamesh's ego holds up when I throw this thing at him."

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

Just then, an alarm blared, signaling the approach of enemy Servants. Gudako's grin widened even further, her eyes gleaming with excitement. 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 with surprising agility. 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. "Just gotta make sure we watch out for the tail."

With that, they marched into battle, their newest summon—a sleek, terrifying Xenomorph—ready to prove itself as the latest oddball addition to Chaldea's growing family.
