May I ask? Since disaster has Intelligence just like human, would a lower rank disaster has a possibility of working for the higher rank one? Or do all of them work alone all the time?
Also, when turning into Dai, does the owner of the part of demon/disaster's meat we eat has to be dead for it...
I do have ideas. Something that can be use as a plot twist and add some element of surprise. But I'm not sure if it'll fit your plan of how the story will goes, if you already have them. Mind if I send you a PM to discuss it?
