Accomplishments of the Duke's Daughter v.1 – Reia (Reia - Illustrator Hazuki Futaba)

I’ve read Common Sense etc. via an online fan translation. Actually, I first encountered “Accomplishments of a Duke’s Daughter” as an English-Language manga, and then went looking for a text version online.

It’s been fun to read. The characters are engaging and there’s a real story being told.

Descriptions of CSDD tend to be misleading about what it’s about. The scene-setting is appropriate for a romance: The protagonist finds herself in the medeveloid world of her dating sim, only instead of being the romantic lead she previously played in the sim, she is the antagonist - the girl who bullied the heroine and lost and is now about to receive her comeuppance.

The protagonist (and the author) walk away from that trap in the first chapter. The story becomes the story of Iris (the protagonist) taking advantage of her position (and her knowledge of our world) to improve her fief and make people’s lives better - within the context of a society in which she has more enemies than she realizes.

The fief-improvement plot is shallow, because it depends on development being easy. Iris knows, from our world, what a bank is, so she tells people about banking and they exclaim “good idea!”. In fact, banks go back a long ways. FAILED banks go back a long ways; it’s easy to get it wrong. It’s easy to get land registration wrong - a lot of modern countries are still working on it - and a common failure mode is that the land winds up registered to the well-connected. A lot of modern countries get public education wrong too. On a more-frivolous note, I looked up the history of chocolate-making, and milk chocolate turns out to be a genuinely-hard problem. My general point is that Iris’s successes are improbably easy: Technical, social, and political obstacles are ignored.

On the third hand, that’s kinda-okay, because CSDD isn’t really about Iris improving her fief and the lives of her people either. It’s an important subplot, but in the grand sweep of the story, the main questions are “Who will marry whom?”, “Which faction will prevail?”, “When and how will a war break out?”
