Maou-sama, Re Re Revenge!

Middle schooler Mada Ooma remembers a former life as the Demon Lord, and carries a single regret from it: never having confessed her feelings to Lili, her devoted attendant. She believes that love is forever out of reach — until Lili inexplicably appears before her in this new life. A cheerful, wholesome romantic comedy that braids together the past and present of a onetime Demon Lord who now finds herself completely at the mercy of the one she adores.
