Luminous Valentine paced restlessly in her chambers within the her castle. It had been too long since she last indulged in the taste of blood, and the hunger gnawed at her insides with increasing fervor. As she prowled, her blue and red eyes fixated on the moonlit sky outside, casting an ethereal glow upon her porcelain skin.

"Rimuru..." she murmured to herself, her voice a melodic whisper. "It has been far too long since I savored the warmth of fresh blood upon my lips."

Her thoughts drifted to Hinata, the valiant holy swordswoman whose essence beckoned to her like a forbidden fruit. But every attempt to draw near was met with a swift rebuke, Hinata's righteous blade acting as an impenetrable barrier between them.

Frustration mingled with desire, fueling the fire that raged within her veins. Luminous needed to feed, and no mere mortal could deny her for long.

As if sensing her restlessness, a knock echoed through the chamber, followed by the sound of the door creaking open. Rimuru Tempest, the ruler of the Jura Tempest Federation, entered with a cautious smile upon his face.

"Luminous, is everything alright?" he inquired, his azure eyes reflecting concern.

Luminous turned to face him, her lips curling into a sly smile. "Oh, Rimuru, everything is just fine," she purred, her voice dripping with honeyed charm. "I was simply...admiring the night sky."

But Rimuru was not so easily deceived. He had known Luminous for far too long to miss the hunger that burned within her gaze.

"Luminous, please," he began, his tone gentle yet firm. "You know we cannot afford any...incidents."

Her smile faltered for a moment before returning with renewed fervor. "But Rimuru, I am simply craving a taste of something...exquisite."

Before Rimuru could respond, a sudden commotion outside drew their attention. The door burst open, and Hinata strode into the room, her expression one of disapproval.

"Rimuru, I must speak with you," she declared, her voice unwavering.

Rimuru's eyes widened in alarm, realizing the precariousness of the situation. Luminous took advantage of the distraction, lunging forward with supernatural speed.

In an instant, she had Rimuru pinned against the wall, her fangs bared in anticipation. Hinata's eyes widened in shock at the sight before her, her hand instinctively reaching for her sword.

"Luminous, what are you doing?" Rimuru exclaimed, his heart racing with a deep blush.

But Luminous paid him no heed, her focus solely on the tantalizing aroma that emanated from his veins. With a predatory grin, she leaned closer, her breath hot against his skin.

"Hinata, it seems you've caught us at quite the...awkward moment," she taunted, her voice dripping with mischief.

Hinata's expression darkened, her sword at the ready. "Release him, Luminous, or face the consequences."

But Luminous only laughed, the sound echoing through the chamber like the toll of a funeral bell.

"Oh, Hinata, you always were such a killjoy," she chided, her eyes gleaming with hunger. "But fear not, I have no intention of harming our beloved Rimuru...at least, not yet."

With a final smirk, she released Rimuru from her grasp, stepping back with a graceful flourish. Rimuru stumbled forward, his breath ragged with relief as he regained his composure.

Hinata watched them both with narrowed eyes, her hand still poised over her sword. "Luminous, I will not hesitate to strike if you pose a threat."

Luminous merely chuckled in response, her gaze never wavering from Rimuru's form. "Oh, Hinata, you wound me with your distrust," she said, her voice laced with mock hurt. "But rest assured, I have no intention of causing trouble...for now."

And with that cryptic promise hanging in the air, Luminous vanished into the shadows, leaving Rimuru and Hinata alone in the dimly lit chamber.

As silence descended upon them once more, Rimuru let out a shaky breath, his heart still racing from the encounter. Hinata watched him carefully, her eyes softening with concern.

"Are you alright, Rimuru?" she asked, her voice gentle.

Rimuru nodded, though the memory of Luminous' hungry gaze lingered like a dark shadow in his mind.

"I'm fine, Hinata," he replied, forcing a smile upon his lips. "Just...a little shaken, is all."

But Hinata could see through his facade, her gaze piercing through the layers of deception to the vulnerability that lay beneath.

"Rimuru," she said softly, her voice barely above a whisper. "Be careful around Luminous. She may seem charming, but beneath that facade lies a darkness unlike any other. I should know. She tried it on me several times."

Rimuru nodded in silent agreement.
