Madougushi Dahliya wa Utsumukanai

After dying from overwork in Japan, Dahlia Rossetti is reborn into a world shaped by magical tools. Raised by her father Carlo, a respected artificer, she follows his craft and uses memories from her former life to invent practical new devices. The future she expects collapses when Carlo dies unexpectedly and, shortly before their wedding, her fiancé leaves her for another woman.

Rather than bow her head, Dahlia decides that the rest of her life will belong to her. She expands her work, creates tools no one has thought to make, and forms an unexpected friendship with a knight who draws her into a wider circle of people and opportunities. Between building a company, negotiating with merchants and nobles, and learning to trust others again, Dahlia discovers that independence does not have to mean being alone.
