Chapter 1: A New Arrival at the Sakamaki Mansion

The sun had just begun to set, casting a warm orange glow over the sprawling Sakamaki mansion. The Sakamaki brothers, known for their mischievous and often cruel ways, were gathered in the grand foyer, awaiting their father's return. Yui, their loyal and obedient servant, stood quietly by the side, her eyes fixed on the entrance. Just as the brothers were starting to grow restless, the sound of tires screeching and engines roaring echoed from outside. The family driver, Takeshi, rushed into the foyer, announcing the arrival of their father, Shinobu Sakamaki. Shinobu strode into the foyer, a sly smile spreading across his face. Beside him stood a young girl, Mori, with striking white hair and piercing blue eyes. She looked fragile and delicate, her meek demeanor a stark contrast to the bold and confident atmosphere of the Sakamaki mansion. "Ah, my dear sons," Shinobu said, his eyes gleaming with excitement. "I'd like you to meet Mori, your new... companion." The Sakamaki brothers exchanged intrigued glances, their faces lighting up with curiosity. Ayato, the eldest, took a step forward, his eyes fixed intently on Mori. "So, you're the new toy, huh?" he said, his voice dripping with sarcasm. Mori's eyes widened slightly, and she took a step back, her hands clenched into fists. For a moment, she seemed to be frozen in fear, but then, in a swift and unexpected motion, she lunged at Ayato, her fist flying towards his face. Ayato, caught off guard, didn't have time to react. Mori's fist connected with his jaw, sending him stumbling backward. The other brothers burst out laughing at the sight of Ayato, his face reddening with shock and pain. "Ah, it seems Mori has a bit of spirit," Shinobu said, chuckling. "I'm sure you'll all get along famously." As the brothers continued to tease Ayato, Mori stood her ground, her eyes still fixed on him. "M-Mori," she stammered, her voice barely above a whisper. The room fell silent, with all eyes on Mori. "That's your name?" Ayato asked, rubbing his sore jaw. "How... original." Mori's face remained expressionless, but her eyes flashed with a hint of defiance. She took a deep breath and repeated, "Mori." The Sakamaki brothers exchanged amused glances, and Shinobu smiled, satisfied with the introduction. "I think it's time for Mori to settle in. Yui, please show her to her room." Yui nodded and approached Mori, leading her towards the stairs. As they ascended, the Sakamaki brothers watched, their curiosity piqued about this new, feisty addition to their family. The mansion's doors closed behind Mori, and the brothers dispersed, each lost in their own thoughts. Little did they know that Mori's arrival would set off a chain of events that would shake the very foundations of the Sakamaki mansion.
