After being reborn as Leonora, the illegitimate daughter of the Hachaina dukedom, she finds herself trapped in a story where her family is destined for destruction. Although this new life is far better than the betrayal she suffered in her previous one, Leonora refuses to accept a tragic ending that is already written. Determined to change her fate, she plans to tame powerful beasts, master the mysterious power of auror, and do whatever it takes to save her family. However, she soon discovers that she is not the only one who knows the story — another reincarnated person has entered this world with the goal of ruining her plans. With time running out, can Leonora rewrite destiny and prevent the fall of House Hachaina once and for all?
