Ferdinand senses danger on the horizon. Dark clouds hang over him, twisting and turning into a dense miasma of unease. Meanwhile, Rozemyne prepares for winter, conscious that her move to the Sovereignty is fast approaching. Her fourth term at the Royal Academy begins, she meets new faces at the fellowship gathering...

Then something strange happens.

Rozemyne goes somewhere unexpected, where she finds something even more unexpected—and that’s only the beginning. How will the saint respond when an incident in Ahrensbach leaves everyone else feeling defeated?

“No matter what happens, I’ll protect you.”

Pressing events are set in motion in the newest volume of this biblio-fantasy. Includes two short stories and four-panel manga by You Shiina.
