A journey into nothingness
In the kingdom of Montesis, where magic is forbidden, Don (Sei-naru Shaw), a 129-year-old repairman and technician with elemental abilities, dreams of protecting Mary and creating a peaceful home, but loses his powers. His life changes when he is forced to become a Protector to maintain order and world peace, just as his parents were in his forgotten past.
The journey begins when Don falls in love with the beauty and culture of the kingdom of Montesis during his first expedition. This world is divided between two magical forces: the positive ether and the negative ether (“the Nothing”), the latter ruling Don and making him a magnet for the dark forces of the underworld.
As the sole survivor of his race, Don becomes the target of Earth's most powerful king and Mei-Wei, one of the most influential women for her special medicines.
The conflict escalates after the destruction of his village, the murder of his teacher and his platonic love, Mary's mother, which follows the appearance of a prince from the underworld, who plans to unleash chaos through the forest.
Consumed by revenge, Don accepts Mei-Wei's offer, though he refuses to be what his father was, the Protector, revealing his darker, more apathetic side. As the defenders of the realm outnumber him in strength, Don will compensate with tactics and much violence, beginning his descent into darkness. However, an inner voice persists, warning him of the consequences.
