Isekai Tensei shite Majo ni Natta node Slow Life wo Okuritai no ni Maou ga Nigashite Kuremasen

Miya, a diligent office worker, lived a mundane life as a secretary. However, her existence took a drastic turn when she lost her life and was reborn in a mystical realm as Miya of the demon tribe. In this new world, she secured a position at the Demon King's castle as a secretary once more. Despite her efforts, she couldn't tolerate the harsh treatment from the Demon Lord, and she promptly resigned in protest. Miya then relocated to the human world, adopting the persona of the witch Miriam, and began to lead a tranquil existence. She was lavished with attention by her loyal knights and apprentices, allowing her to indulge in a life of leisure. Yet, her serenity was short-lived, as the Demon Lord launched a surprise attack, shattering the peaceful atmosphere she had grown accustomed to.
