Part 5, the final chapter of this biblio-fantasy, begins with a colder-than-usual winter...

Ehrenfest’s first winter without Ferdinand feels harsher than usual. An unexpected betrayal within the former Veronica faction makes the purge even more urgent, and those who know about Georgine’s destructive goals are comparing her to the Goddess of Chaos. Meanwhile, Rozemyne throws herself into her studies at the Royal Academy to stave off the loneliness that eats away at her. She hopes to win over the students of the former Veronica faction and save their lives, and she meets a new archnoble librarian from the Sovereignty while she’s at it. Our ambitious heroine finds herself balancing classes from both the archduke candidate course and the scholar course, and she soon realizes that her environment has changed drastically once again! This first volume of Part 5 is capped off with two short stories and four-panel manga by You Shiina.
