Most of the leaders of the great powers all had heard the news from Jean that the Demon King is still alive
Jean also told them that the Demon king power had decreased.
The Demon King might have some methods to recover a new and more powerful body. When hearing about this the great powers all think about one thing.
Death Monarch.
Of course, even then, most of the great powers did not known that the reason this calamity happens at Earth Prime is because of Azief.
To them, the one that have created this calamity is none other than the trickster.
There is no reason for Hirate to lie on this matter.
Those who knows the truth did not say anything. Jean knows who is responsible.
But even he did not say it. There is also Hikigaya that surely have seen through the lies and knows that Loki is innocent.
But even he was silent on this matter
