In "Ascendance of a Bookworm Season 2," Myne discovers the Holy Church uses mana for its relics, recognizing an opportunity to address her critical mana disorder. Impressed by their extensive library, she eagerly pursues admission to the Church. In exchange for her service and abundant mana, Myne receives the status of a noble-born apprentice priestess, despite her common origins. For her, titles and mana concerns are insignificant compared to her newfound access to books.
Transitioning to this new phase in her world, Myne finds that achieving her dream comes with substantial sacrifices. The noble hierarchy is cruel and politically charged, leaving little room for compassion. She faces discrimination between the noble blue robes and common grey ones, the High Priest's schemes against her, and challenges with her new retainers. With support from her family, friends, and the enigmatic Head Priest whose motives remain unknown, Myne overcomes these obstacles to advance on her path toward becoming the ultimate librarian.
