     How vast is human knowledge about angels and demons? Do these creatures exist? Are they real? I can mention, there are several stories: wolves looking for meat at night, vampires looking for their next victim and terrifying animals stalking innocent beings while they sleep. In this environment, Bryan Lee is born, a boy who is considered abnormal among humans, but trained in the martial and mystical arts.
     Despite not knowing his origins due to his family's numerous secrets, Bryan manages to grow and develop bonds with the Earthlings. However, his life turns around when some portals to another world are opened and creatures begin to gain access to planet Earth.
     In this context, Bryan discovers that he is part of a group called the 'Guardians', warriors who act in the shadows and are destined to protect humans. And, to add, he is also part of an ancient legend: he will be the destroyer of Belial, a creature with powers to unite the parallel worlds with Earth.
Exotic places, different planets, guardians and bestial animals are part of this adventure-filled story, in which good and evil will face off. However, only one side will win!
