Heroine? Saint? No, I'm an All-Works Maid!

'''Heroine? Saint? No, I'm an All-Works Maid!''' is a reincarnation isekai.

Ritsuko Mizunani is a brilliant child from Japan, who could advance any field of science she chose; despite this, she is obsessed with becoming the perfect maid. She dies in a plane crash on the way to England to train, being reborn in another world as Celesti McMurden and retains her same brilliance and passion. After the death of her mother Serene, she learns in the will that her father is Count Cloud Reginbass; the two were in love but Cloud's father wouldn't have it. Knowing there's no way the Count would let her follow her dream, Celesti decides against contacting him and promises herself and mother's memory that she would become the best maid ever; using magic to look Japanese again and changing her name to Melody Wade.

Trivia

 * Melody has no clue that she reincarnated as the heroine of an otome game; luckily her precaution against being recognized helped her evade knights her father sent to look for mother, and her by extension, paid off.
 * However, the story formula means her father won't give up on trying to find her. Completely vexing for Melody when this happens, as she has ZERO interest in being a noble.
 * As Melody is the heroine of an otome game, it means that she will eventually be targted by the dark forces she was supposed to deal with as a saintess.
 * The narration at the end of chapter one implies that God realized it majorly screwed up by choosing Melody; seeing as it started saying those with her power could take over the world before admitting there was a fine line between brilliance and foolishness (referring to Melody's choice to use the blessing to be a maid).
 * Melody is ignorant of how she's the strongest magic practioner in the world.
