Clash of Titans

Jibril's fascination with Riku's sword was undeniable. Her eyes sparkled with curiosity as she examined the luxurious weapon in his hand.

"You can actually project a physical sword. Is this also a kind of magic? I haven't seen this kind of magic yet. It really makes me more and more curious about you," Jibril mused warmly, her interest piqued by this unfamiliar skill.

However, Riku's response was less enthusiastic. He knew that the sword he now wielded, a product of Unlimited Blade Works, was not the original. It was a mere imitation, a B++ treasure, while the real thing, the one contained within the Noble Phantasm, was far superior. Still, Riku's energy surpassed that of its original owner, Emiya Archer, potentially allowing him to unlock the true potential of this power.

Though tempted to retreat from this unexpected encounter, Riku realized it was a crucial opportunity to assess his current abilities. He couldn't simply back down now, not without understanding his newfound strength better. His resolve solidified, and he prepared for what lay ahead.

With a burst of energy from his Hermes Boots, Riku launched himself into action, leaving a trail of shadows as he closed the distance between himself and Jibril in the air. His silvery sword gleamed with anticipation.

The clash of their swords filled the air with energy sparks as they fought. Jibril calmly assessed Riku's speed and technique, noting his potential and shortcomings. She remarked, "Pretty good speed. It's not much worse than those stronger demons. However, your strength seems to be at the level of an ordinary demon. And there is no skill in wielding a sword."

Riku bristled at her critique but didn't lose his resolve. He attempted to land a blow, only to be met with Jibril's impenetrable defensive barrier. Undeterred, he tried to engage her further, but the gap in their power became evident as Jibril easily deflected his attacks.

In a desperate maneuver, Riku pushed his Hermes Boots to their limits, attempting to close in on Jibril once more. He swung his sword with determination, but it was futile against her formidable defenses.

Jibril swiftly countered, slashing through the air with her energy sword, narrowly grazing Riku's neck. Blood trickled down his face as he pulled away, realizing the vast difference in their strength.

"The power gap is too big. I'm not her opponent at all," Riku admitted, his face darkening with the weight of reality.

Jibril, perched high above, maintained her intense fascination with Riku. She urged him to use any hidden abilities he possessed, given his mysterious nature. She mentioned his current "skull level" of LV.3, a classification system Flügel used to rank different races. Humans were considered insignificant in their eyes, akin to ants.

Riku had challenged Jibril to test his strength, but her interest in collecting strong individuals was well-known. Her obsession with the unknown was evident, and she was not one to back down from a challenge.

With resignation, Riku agreed to reveal his hidden abilities. Jibril's excitement was palpable as she eagerly awaited his demonstration.

With words that resonated with power, Riku's surroundings changed dramatically. His clothing billowed as an Elemental reaction enveloped him, isolating the area. He began an incantation, reciting the famous lines from Unlimited Blade Works.

As he concluded, both Riku and Jibril witnessed a profound transformation in their surroundings. They found themselves in a dark world illuminated only by the radiant moon above. The ground was covered in sand dunes, each adorned with countless extraordinary swords.

Jibril looked around in disbelief, her eyes wide with astonishment. She couldn't help but ask, "Where... is this?"

Riku, now carrying the silvery sword with confidence, replied, "Welcome to my world, Flügel, Jibril." His voice was filled with indifference, hiding the depths of his newfound power.
