Both stories are about girls that are reincarnated as the villainesses of an otome game they once played, and show their lives after they receive punishment for their "sins". In Koushaku Reijou no Tashinami the MC is made the acting lord of a fief far from the royal capital, and in Akuyaku the MC gets banished from the kingdom and becomes a nun. Both girls try their best to succes in business by using the knowledge from their own world, and are part of the nobility.
Both works have a shoujo demographic and show the romantic development in the MCs lives as well.
