Ascendance of a Bookworm: Part 5 Volume 9 [EPUB ebook] 

The Battle of Gerlach begins at last. Together with Matthias, Rozemyne must defeat the cold-blooded giebe Grausam—but an unexpected development makes that easier said than done. Body doubles, collateral damage, even more dark plots transpiring in the shadows… How does their inevitable battle play out, and what happens to Ehrenfest in the aftermath? Behold the full extent of the explosive war shaking Yurgenschmidt to its very foundation!

Time is running out in the newest installment of this biblio-fantasy. Once again, this volume contains more than one hundred pages of original content not featured in the web novel—and more four-panel manga by You Shiina!
