Rudo lives in the gypsy neighborhoods of a flying city that the wealthy elite, who indulge in their lavish lives, throw their trash into, known as the Void. One day, his life is turned upside down when he is falsely accused of being a murderer, leading him to face the harshest of punishments. Rudo will paint the depths of the Void with the trash of the people. The filth of the garbage thrown from above on the earth he has fallen to gives rise to depraved creatures. With Rudo's desire to take revenge on those who condemned him to this hell after learning the truth, he gains new strength and joins an organization called the Servants, which hunts the Depraved Creatures roaming around, as he tries to return to where he once was.
