Fuzetsu is a field separating a region from time and space. In this place everything freezes in one position. Only denizens, flame haze and a few more species are able to move there.
This field is often used by the denizens to suck up the live from the innocent and defenseless humans. In this field take place the battles between the denizens and the flame haze.
After a battle finishes, is needed somebody’s living energy so the damages from the battle are repaired. After everything is fixed the field is removed and everything continues, like nothing ever happened.
