Accomplishments of the Duke's Daughter

A young Japanese office lady is killed in a vehicular accident. After losing consciousness, she awakens in another world in the body of Iris, the antagonist of an otome game she had been playing before her demise.

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.

Thinking fast, Iris manages to leave the school with her dignity intact and upon returning home, is also able to avoid being sent to a nunnery, the fate of the original Iris. Impressed by her rational thinking, Iris's father Duke Louis de Armelia leaves her in control of the Armelia fief in place of her brother Bern, who is one of Edward's supporters and is also in love with Yuri.
