The series was initially self-published on Shōsetsuka ni Narō starting on February 7, 2015, and Fujimi Shobo began publishing a light novel version in November of the same year.

To her shock, she discovers that she has reincarnated at the exact moment where Iris' former fiancé, Prince Edward, confronts her in front of the entire school over her bullying of Yuri, the illegitimate daughter of a baron and the game's heroine.

As the series progresses, Iris uses her previous life's knowledge to bring about major, positive changes to her fief and the kingdom, such as the concept of banking and schooling for commoners who would otherwise not receive education.

She also introduces commercial products that had not previously existed or were only available in a crude form, such as chocolate and cosmetics, going so far as to start her own successful corporation.

This brings both positive and negative attention to Iris, her family, and the fief, especially as it angers Prince Edward, who wanted her to be severely punished.

Accomplishments of the Duke's Daughter was initially self-published through the novel publishing website Shōsetsuka ni Narō.
