Maou-sama, Re Re Revenge!

Ooma Mada appears to be an ordinary middle school girl, but she carries the memories of a far more fearsome existence—she was the Demon Lord in her previous life. Conquering realms and commanding legions paled in comparison to her sole lingering regret: she never mustered the courage to confess her love to Riri, her trusted attendant. That unspoken affection followed her beyond the grave, a bittersweet ghost she assumed would remain forever unresolved in the pages of her past life. Yet reincarnation has a strange sense of humor. In her new life as a seemingly normal student, Mada's quiet routine is shattered when Riri suddenly materializes before her very eyes. The love she thought impossible now stands right in front of her—but this is no fairy-tale reunion. Instead of a shy subordinate, she finds herself facing a Riri who is playfully assertive, constantly leading the former Demon Lord by the nose and keeping her perpetually off-balance. What unfolds is a bright, effervescent romantic comedy that dances across the boundaries of time. As the ex-tyrant grapples with schoolgirl anxieties and the chaos of her resurrected feelings, she discovers that the true battle isn't for world domination—but for the heart of the very person who seems to enjoy turning her world upside down.
