The Throne of Thorns

You are the newly coronated Queen of the magical kingdom Yuueii who finds more than just safety and refuge in the arms of your faithful Royal Knight, Izuku Midoriya. Always busy, your queenly duties keep you from addressing the ever growing stack of marriage proposals piling up on your desk. Although a few members of the Royal Court suspect that your heart already belongs to the lowborn Knight sworn to be your shield— and only your shield. The whispered rumors of your closeness were highly taboo, and the planted seed quickly sprouts into growing dissent. A commoner serving as the Head of the Royal Guard gives the nobility plenty to gossip about as it is. Yet you can’t help but feel a certain attachment to your devoted right hand. However you have much more pressing matters to attend to when your peaceful kingdom falls under siege by a Warlord driven mad by unseen dark forces.
