Ascendance of a Bookworm: Part 4 Volume 7 by Miya Kazuki

After fainting at a tea party for bookworms, Rozemyne is forcibly returned to Ehrenfest. There, she reunites with her lower city associates and enjoys some long-awaited reading time in the temple... but as peaceful as these winter days may seem, a revelation in the bible threatens to turn her days of reclusion on their head.
Rozemyne’s second year at the Royal Academy draws to a close with interrogation and investigations, which she must face on top of a resolute apprentice who wishes to swear his name to her. Things only become more complicated when she attends the Interduchy Tournament for the first time, and a grave development causes more trouble than ever expected. Can she and Ferdinand manage the chaos so soon before the graduation ceremony?
Tensions between duchies are high in the newest volume of this megahit biblio-fantasy! Includes two love stories of graduated students and four-panel manga by You Shiina!
