There hasn't been a person who could control all 4 elements since the first wielder Bloise Atlantes, until now... Jack Sakuan is a 15 year old in the magic world of Uraha. He is what they call a late bloomer. Everyone in their world has control over at least one element. Fire, Earth, Air, or Water. Most can only control one element. He hasn't shown an aptitude for any yet. However there are the few that can control more. Those are the kings knights. If you show aptitude for more than 1 element then you are automatically put into a rigorous boot camp to find your elements. There are only 5 people in Uraha that can control 3 elements. The king, his son, and his 3 best soldiers. When Jack shows aptitude for all 4 elements he is immediately sought out by the king. Jack doesn't want that, he flees and looks for answers on how he came to be the first 4 element wielder in a few millennium, while trying to find out why the king seems to "need" him.
