Grey Rogers, a tyrant king, is killed by poison and reincarnates into the same world, but in an alternate realm where magic and mystical creatures exist, some hostile and some peaceful. He finds himself as the heir to the throne of the Kingdom, now also part of the royal family as the crown prince. Fortunately for him, two things accompany his return. First, he is determined to dominate kingdoms to increase his magical strength as a wizard; second, he discovers he is also a descendant of the greatest swordsman of the era, inheriting all of his skills.
