Martial Emperor of Blue Star, Turned into a Blood S*ave Girl by a Vampire Princess

At just 17 years old, he was hailed as the youngest Martial Emperor in history, the final shield standing between humanity and the invading forces of another world — the bloodthirsty vampire race.

But in one fateful battle, he was defeated by a mysterious and ancient vampire princess. Instead of killing him, she transformed him… into her blood s*ave. And worse — into a girl.

Stripped of his power, status, and identity, he awakens in the body of a beautiful yet fragile maiden, bound to serve the very enemy he once swore to destroy. Trapped between memories of battle and the instincts of his new body, he must now navigate a twisted world of manipulation, desire, and the faint hope of reclaiming who he once was — or embracing what he’s become.
