Mercedes Grunewald is reborn as a vampire and possesses strength, speed, beauty, and noble status, though her noble title is tenuous due to her mother’s status as a concubine and her father’s indifference. Aware that her current privileges may vanish when he selects an heir, she decides to secure her future independently. Starting at age ten, she begins exploring dungeons. Seeking fulfillment and a purpose beyond what she lacked in her previous life, she aims to carve out a new destiny. Her goals include achieving recognition, wealth, or simply a meaningful existence.
