As early as when she first met Anne and came into contact with Bernadette Gustav, Angel had heard from them that the nine mausoleums belonging to Roselle, who had been assassinated during his advancement to Black Emperor, had not been completely destroyed. Some were fakes disguised as mausoleums required for the ritual.
After she and Klein had opened up to each other about their "transmigration," she had glimpsed their fellow transmigrator's extremism and madness in his later years through the pages of Roselle's Diary. In particular, the two hidden mausoleums mentioned in the diary had set her imagination running wild. She believed that this Black Emperor might not have perished in the assassination, and that he might still have a slim hope of resurrection.
Thus, when she learned that Bernadette had discovered a hidden island deep in the Fog Sea, she was even more excited than Klein.
"Very possibly, but Bernadette and Anne can't be certain yet. They only tracked Nast to the vicinity of the island and prayed to me in advance as a precaution. I think Anne might also try to contact you through your contract later to ask for support."
Angel nodded without trying to leave the gray fog and return to reality to confirm it. Just as Klein left avatars above the gray fog to receive prayers, prayers directed at her honorific name could also be relayed to her mirror person. There was no need to worry about missing any pleas for help.
She then asked:
"If Roselle's mausoleum really is there, should we go to the island? If, as we previously suspected, the emperor really was corrupted by the Mother Goddess of Depravity in his later years, Bernadette and Anne probably won't be able to handle it."
There were actually two concerns behind her words.
