Maou-sama Exchange!!

Facing annihilation at the hands of an overwhelmingly powerful Demon Lord, the hero Filina and her party are offered a single chance to survive. The Demon Lord proposes to spare their lives on one condition: he and Filina must swap bodies for a full year. The demand is strange and terrifying, forcing Filina to weigh her companions’ survival against the cost of surrendering her own body to their enemy. Atty, a priest and Filina’s childhood friend, immediately objects to the arrangement. Despite his opposition, Filina accepts the Demon Lord’s terms in order to protect her companions. Her decision binds her to the Demon Lord’s condition, setting a dangerous bargain into motion.
