When nine gods invaded a world devoid of magic, they brought dungeons and unprecedented change. A realm torn by endless warfare finally found peace—only to have that stillness shattered by the pursuit of ultimate power hidden within dungeon cores. While humanity races to claim strength, the gods orchestrate nations into conflict, furthering their own hidden agenda. Kiada, a battle tank, achieves what no one has before: becoming the first to conquer a dungeon and claim its ultimate reward. But destiny rarely unfolds as promised. Instead of fortune, she receives the Blood Servant System—and with it, an unexpected burden: leadership of one of the four Guilds controlling her city. As Kiada ascends from obscurity to Guild Master, she uncovers truths about herself and the world deliberately kept hidden from humanity. Gathering blood servants, recruiting guild members, and forging new bonds of first love, Kiada strengthens her guild from its foundations. She hunts ancient artifacts, establishes trade routes, and races to understand the gods' true purpose before their machinations consume the world. Love transcends time and eternity, and within Kiada burns a spark that refuses to be extinguished—even as she transforms from weakness into strength, discovering exactly who she was meant to become.
