Warhammer Fantasy: My Yandere Girlfriend Is a Daemon of Change

Also known as "The Shapeshifter and I Conquered the Human Empire Together" and "Guns, War, and Medieval Warhammer"

Rosen and his yandere student Su Qingying died together. When they opened their eyes, both had transmigrated to the world of Medieval Warhammer.

Rosen became an Elector of Wissenland and Nuln, commanding guns and mighty armies. He marched east against the Vampire Counts and south against the savage Beastmen. Through cooperation and rivalry with Emperor Karl Franz, he gradually became the true uncrowned king of the Empire’s south.

Su Qingying, however, fell to Chaos and became Tzeentch’s most mysterious daemon: a Changeling.

She founded a cult of deceivers within the Empire, laying secret plans and advancing step by step, all to overthrow the entire human Empire.

The master and student, who should have been mortal enemies, remained entangled in the most twisted of ways.

Whenever Rosen was in danger, Su Qingying would always appear in time to cut down his powerful foes and eliminate his political rivals;

With Tzeentch’s magic and schemes, she handed him cities, wealth, and power, hurling all her obsessive, near-mad love at him.

Just as the Empire was beset by internal and external crises and stood on the brink of collapse, the vampire armies of Sylvania watched hungrily, Chaos forces stirred in the Brass Keep of the northern frontier, and even Emperor Karl’s army was secretly destroyed by Su Qingying.

At times she was an innocent young woman, lurking by Rosen’s side; at others, she took the emperor’s place and ignited civil war within the Empire.

Within, a madly obsessed yandere demon disciple clung to him. Without, vampires and a tide of Chaos waited to strike. The Empire was on the brink of disaster.

This time, should Rosen save the Empire, or bring back the student who had long since fallen into the abyss?
