Devil Dukes' fight (I)

The fiery crimson sun and the black sun with a grey halo radiated so much energy that the temperature in the Yuru continent grew unbearable for Rank 0 life form. 

Millions of lesser devils, unfortunate enough to be in the open and outside a city's protection fell to the ground as they felt their lungs burning due to the air's temperature. 

Countless lives ended in a matter of seconds just because two individuals decided to stop restraining the immense power they carry inside their bodies. 

The first stage for a true Rank 6 life form is called Hollow Sun Domain Stage. The term sun in their title refers to the fact that a Soul Law Domain existence could take the place of a Low World's sun if he so desired, bringing warmth and energy to the billions of lives inside it.
