Marie Fou Lafuan

Marie is the daughter of a viscount family and was Leon's younger sister in her previous life. Armed with knowledge from the game, she seized the protagonist's role and declared herself a "saint," scheming to build her own reverse harem. Though initially driven by selfishness and greed, her plans ultimately collapsed. After reuniting with Leon as siblings, she found herself financially supporting five destitute princes, transforming from a calculating schemer into an exhausted, pitiable workhorse.
