@mister_nobody its a cycle.... for demons. Isn't Iruma human? This was a simulated one that used the power in his gluttony ring right? and from the sound of it, the ring used up alot of power to pull it off. I doubt we will see it again for a long while since Iruma doesn't have a natural evil cycle.
@wilddeath
The ring told him that there was the chad phase and I think there was another thing too that he had to show so everyone would beleive he was a full fledge demon. So he has to become Cadruma now and again so no one doubts his demonic lineage
@democarplus Ah got it. I guess that makes sense that the ring would have to do it now and again. But i still stand by my statement that it won't be very often if the drain on it was as bad as it implied.
