Former nursery school teacher Musashi Ayaka is reincarnated as “Aria,” arriving at the mansion of a young girl named Fia — a child who is fated to grow up and destroy the empire as a villainess. Aria has one and only one mission in this world: as Fia’s childhood caretaker, pour unconditional love into her and raise her in the right direction before she becomes a villainess.
