Since I Have Been Reincarnated as the Daughter of a Duke, I, the “Girl Inside,” Will Enjoy Being a Girl as Much as I Can!

A humble man in his thirties, living in modern Japan, after successfully evading the fate of becoming a mage, suddenly dies and gets reborn in an 18th-century look-alike world, where magic exists, into a duke’s daughter. Is this an otome game? Or some sort of RPG game world? While pondering the situation, the man, a lover of dolls and plushies and also a person with an interest in all things girlish, the so-called “girl inside,” decided to indulge in his hobbies without worries after becoming a girl and live a carefree life. His girlfriend from the previous world, too, gets reincarnated, and into the prince, no less! This pair of close and trusted people were arranged to be married to each other. Due to approaching puberty, both of them, who have changed sexes, must come to terms with the expectations society holds for each of them… maybe. Without any common knowledge of the world, armed only with the barebones information from a past life, this is the story of a man reborn as a noble lady who is to become a fine (?) queen while inventing various sanitary productions with great care in this 18th-century world on the cusp of the industrial revolution.
