Celeste is attending to her domain.
In fact, perhaps because she inherited a portion of the chakra's nature, her God Kingdom can be divided into two layers, one being her Starry Blood Sea Wheel, and the other part is the land she inherited from the Blood Queen after being acknowledged by the Abyss—a land constantly being bombarded, which is primarily the latter.
The dust of the great battle has settled, devouring the majestic power brought by two Half-Demon Lords, flowing and settling within her as if she were a newly born galaxy. Celeste has rapidly increased her power, almost reaching the limit of a "Demon Lord." If now Celeste were to confront Dagun or the Bound Virgin, she is confident she could handle them by herself without Ybur's help.
This finally allows her to turn her attention to this heavily ravaged Abyssal Domain.
With her increased strength, this Abyssal Domain also grows larger and more flexible.
