Only when Eclair transferred to Holy Trinity Private Academy did Anastasia get to know her more.
She is the sole daughter of the Remilly's, a couple who both work as researchers and doctors. They have a number of notable achievements in various fields of science, are renowned to be some of the most capable and outstanding practitioners in these disciplines, and own manifolds of wealth that nearly rival the August's.
Her early education took place abroad, though she was homeschooled for the most part. Now that she's in high school, the family returned to their home country and she had been finally allowed to attend a private school.
Overall, looking at her background alone, Eclair is a perfect match for Lucien.
