Boukun Ikka no Akachan desu ga, Kazoku ni Dekiai Sareteimasu

She had devoted her life to guarding the kingdom's treasured Magic Crystal, only to be falsely accused and sent to her death on the execution platform. Yet when she opens her eyes once more, she finds herself reborn—as an infant, complete with every memory of her tragic past. Her second chance grants her the one dream she never achieved in her first life: birth into nobility. But destiny proves cruelly ironic, for her new family is none other than a notorious house of tyrants—and worse still, this household is fated to meet its ruin in the years to come. Determined not to let her story end in tragedy twice, she makes a resolute vow: she refuses to perish, and she will protect this doomed family by any means necessary. And so begins an unlikely tale of survival, as a sharp-witted baby navigates life within a household bound for destruction. Along the way, she forms an unexpectedly endearing bond with her hopelessly clumsy father, and armed with the wisdom of her past life, she fights tirelessly to rewrite her family's grim future—and secure her own.
