Histoire

Manga adaptation of Part 5 of Honzuki no Gekokujou. Winter looms heavy in Ehrenfest, where Ferdinand departed. A tip-off about Georgine, a "Goddess of Chaos" who revels in mayhem, hastens the purge. Meanwhile, Rozemyne, now a third-year student at the Royal Academy, is busy trying to shake off her sense of loss. In the dormitory, she persuades the children of Veronica's former faction to avoid being implicated, while the first day of classes for lord candidates begins at the academy.
