Her partner is Ortius, nicknamed the "Black Wolf King," a barbarian king rumored to have only the ability to fight with his beast-like body. However, on the day of the wedding ceremony, Edel meets a handsome young man with tall, black hair and an intelligent light in his eyes. Before long, their encounter develops into a situation that threatens the very survival of the kingdom... (Source: Kadokawa, translated)
