Karfes' Blades - Straying Love

This world is ruled by three Guardian of the Skies. They protect the Earth from evil, but now, the Karfes is intent on taking over. Every 300 years, a new Guardian will be born on Earth, he inherits the previous Guardian’s powers. When the Karfes, who were originally protectors of the Guardians rebelled against them and wanted control over Earth, they had to seek out the newest Guardian and kill him before he turns 18, that is the age he will take over the position of third guardian, which will make the Guardians of Skies invincible. And I am that person, Demitrius Skyler.
What happens when the newest Guardian falls in love with a normal human? Will he get distracted from his role as the girl Agnes Jones challenged him as to who is more of a charmer? Will he be able to run from the Karfes when his 18th birthday draws nearer or will the world stop and fall into the hands of the Karfes?
