There's a lot to like here as we watch two dorky leads get to know one another and learn to enjoy life in an environment that's safely away from all the hardships they've faced in the past. 9/10 - Anime UK News

Allen, a powerful sorcerer feared as the Demon King by all in town, wants nothing more than to enjoy his solitary existence, deep in the forest-that is, until the day he discovers a young woman unconscious in his neck of the woods and saves her from a band of knights. He soon learns the girl, Charlotte, was betrothed to the prince of the neighboring kingdom before he framed her for vicious crimes and forced her to flee for her safety. Moved by her plight and the pitiful life this disgraced noble had led, Allen stakes his own life on a promise: to give Charlotte a crash course in all that is naughty, and make her the happiest woman in the world!
