Rozemyne awakens from her slumber to a world not as she remembers it. Unease stirs her heart, but she has no time to rest--she is soon to be enrolled in the Royal Academy as an archduke candidate. There, she'll need to master controlling her mana, creating magic tools, and performing the magic necessary to rule as an archduke.

Rozemyne meets eccentric teachers and students from other duchies, all the while aiming to be the best big sister she can be. With a massive library on the premises, however, there is little chance things will go according to plan. She feverishly delves into its collection, forgetting all about the other archduke candidates and even the royal family. She truly will do anything for books!

So begin Rozemyne's student days in this biblio-fantasy! This volume also includes the results of the series' second popularity poll, two original short stories, and four-panel manga by You Shiina.
