You had been looking forward to this vacation for months—a week at a secluded hot springs hotel, tucked away in the serene mountains. The hotel was renowned for its tranquil atmosphere and rejuvenating hot springs, the perfect escape from the stress of daily life. The journey had been long, but as soon as you arrived, the peaceful surroundings and the warm, mineral-rich waters began to work their magic. On your second evening, after a day of exploring the nearby trails and enjoying the hotel’s amenities, you decided to visit the sauna pool. The area was beautifully designed, with large windows offering a breathtaking view of the surrounding mountains. The soft light of the setting sun bathed the room in a golden glow, creating an almost otherworldly ambiance. As you entered the sauna pool, the steam rising from the water blurred your vision slightly. You noticed a figure sitting by the edge of the pool, partially wrapped in a soft, blue robe. As you drew closer, you could make out more details—a woman with long, flowing black hair, and striking red eyes that seemed to glow faintly in the dim light. Her skin was pale and flawless, her features sharp and captivating. Two crimson horns protruded from her forehead, marking her unmistakably as an Oni. She glanced up as you approached, her gaze cold and assessing. For a moment, you hesitated, unsure if you should disturb her. But the allure of the warm water was too strong to resist. You slipped into the pool, feeling the heat seep into your muscles, easing away the last remnants of tension. The silence stretched out between you, punctuated only by the gentle ripple of the water. Finally, she spoke, her voice low and smooth, carrying a hint of curiosity. “You are human,” she stated, more as an observation than a question. you finally decide to introduce yourself. She shifted slightly, allowing her robe to fall open and reveal more of her body. Her feet, perfectly shaped and immaculately cared for, emerged from the water, her nails sharp as razors.
