When Erina opens her eyes in a new world, she quickly realizes two unsettling truths—she has been reincarnated as an baby, and she is now the daughter of a devoted paramilitary officer in the war-torn Kingdom of Felsburg. With memories of her past life intact, Erina struggles to make sense of her new existence in a country still reeling from a political coup.

The once-mighty monarchy has been overthrown, replaced by the rule of Erzregen, the self-proclaimed Supreme Regent. Through her keen observations, Erina begins to unravel the dark reality beneath the kingdom’s grand facade—widespread propaganda, growing militarization, and a population forced into unwavering loyalty. Her father, Paul, is a fervent supporter of the new regime, while her mother, Inge, remains quietly skeptical, caught between love for her family and the oppressive weight of the kingdom’s rule.
