Ascendance of a Bookworm, Part 5, Volume 2

As snow falls around Ahrensbach's castle, Ferdinand, soon to be married to the duchy's next archduchess, receives a concerning letter. Not only has Rozemyne been summoned by the royal family once again, but she is also being taken to the underground archive hidden beneath the Royal Academy's library. Even as a third-year, she proves to be a source of constant headaches—and the chaos only continues when she manages to pull an unexpected figure into her joint research! The stakes are raised higher still when Lestilaut makes an astonishing suggestion, forcing her to participate in a game of bride-taking ditter with Leidenschaft's spear in hand.
Rozemyne's hand in marriage hangs in the balance in the newest volume of this biblio-fantasy. Includes two short stories and four-panel manga by You Shiina.
