Maou-sama to Kekkon shitai

Things have been quiet in the Demon Queen's domain as of late. Wondering what she could do to ease her boredom, she asks her faithful servant Haru for a suggestion. Haru, smitten by the Demon Queen ever since she saved him from the slave trade at a young age, proposes that they get married. Unsure of what to do, the Demon Queen confides in her maid Maribel but finds that this conversation may not be as helpful as she wished it could be.
