Aira, a commoner whose talent earned her a place as a royal court alchemist, lived a busy and fulfilling life at the palace. But everything comes to a sudden halt when the Second Prince, who refuses to acknowledge commoners, unceremoniously fires her. With nowhere else to turn, Aira opens a small apothecary in a corner of an inn owned by a friend, and before long, it becomes a huge success! Meanwhile, the Second Prince is left scrambling. The noble-born alchemist he installed as her replacement turns out to be thoroughly unremarkable, forcing him to devise a desperate comeback plan. The dazzling second act of a banished alchemist begins here, an otherworld apothecary fantasy, now open for business!
