The story begins with our protagonist—a young woman in her previous life who had always felt unfulfilled, perhaps even trapped by societal expectations. Her memories are hazy, but fragments of her past life linger: a world of technology, routine, and limitation. As she drifts in and out of consciousness, she senses a strange energy around her, a calm yet unfamiliar power flowing through her veins.

When she opens her eyes, she finds herself in a traditional Japanese room filled with the scent of tatami mats. The walls are adorned with swords and the family crest of a samurai clan. As she sits up, she catches sight of herself in a mirror—a different face, with striking features and a piercing gaze. Her new name, she quickly learns, is Minami. She has been reborn as the daughter of a samurai lord, known for his skill in battle and his unyielding honor.
