In this world, a cataclysm has caused the appearance of monsters and other disasters, emerging from dimensional rifts and gradually pushing the world toward its destruction. To face it, some humans having awakened various magical powers are fighting against this apocalypse.
Dora, one of them, has a special “Avatar” class which gives her access to all the other classes, at the cost of great difficulty to level them up. Despite his enormous potential, he chose to appear incompetent to get his team kicked, just so he could live a lazy life with his family, but his habit of fighting and beating the woman's brother the strongest in the Kingdom reveals her talents and she decides to enroll her in the royal academy.
Reluctant at first, his mother gives him the motivation he needs to pursue this past, but little did they know what kind of monster they threw to the world. Dora is not a hero wishing for peace, but a monster getting addicted to the taste of power, wealth, and freedom.
With his strange condition of being not one but many people inside one body, each with a different personality, but the same thirst for more, “they” use a strange system giving them a new vision of the world around them.
Dora pursues an unknown goal until he meets someone who knows more about his true nature than himself and sets him on a path that will nourish his eternal first, to the cost of his humanity, but in a world collapsing, isn't a monster the greatest weapon?
With many personalities in one body, each having a different relationship with different people, a system taking them further and further away from their humanity, and an increasingly hostile world where humans kill each other while monsters slaughter them, could the situation be worse?
Well, it looks like Dora isn't the only one with a system.
