Spring is in full bloom, and Rozemyne is summoned to the Archduke Conference. She performs the Starbind Ceremony as High Bishop, then rests and recuperates by transcribing documents in the library’s underground archive. The ceremony has some unforeseen consequences, however. As tensions rise over the increasingly important “Zent candidates,” Rozemyne finds herself entangled in the web of royal politics. Thankfully, this also secures her the chance to bargain with one of the princes... “When you get an opportunity, take it and profit as much as you possibly can, right? Well, here I go!” Negotiations are underway in the newest volume of this biblio-fantasy! What techniques will the commoner-born merchant saint unleash?! Includes two short stories and four-panel manga by You Shiina.

Upon returning to Ehrenfest, Rozemyne is given a harsh choice to make. The winter purge has made the Leisegangs the dominant power, and their intentions sow distrust within the archducal family. Still, she continues to forge ahead, her way of life gradually inspiring change around her. The feast in celebration of spring is drawing near, and there’s much for Rozemyne to do. The coming weeks bring a long-overdue meeting with the lower-city merchants, more divine protections rituals, the education of the next High Bishop... and a magnificent tale told at the closed country gate. It now falls to the archducal family to overcome history and the divide between factions. Ehrenfest’s ambitious younger generation unites in the newest volume of this biblio-fantasy. Includes two short stories and four-panel manga by You Shiina.

In her determination to access the library as soon as possible, Rozemyne put her absolute all into her studies from the moment she arrived at the Royal Academy. Unfortunately for her, she behaved so unusually in the process that her retainers and professors have grown increasingly worried. Rozemyne finally clashes with the greater duchy Dunkelfelger over Schwartz and Weiss, and a game of treasure-stealing ditter is arranged between the two duchies’ apprentice knights. To make matters worse, she completely ignores proper diplomacy, accepting furtive consultations from the archduke candidates of other duchies and even giving the prince himself romantic advice! Her complete lack of foresight leaves the leaders of Ehrenfest in constant cranial agony.
