Eve did not have to ask Casimir what he meant by those words. She knew perfectly well what he was trying to imply.
The implication of the medallion.
Ophelia asked her to wear it all the time.
While the medallion gave her an unbelievable advantage, it also meant that she had now put another target in front of her chest.
The fact that Ophelia was helping her was bound to attract attention, Eve knew that this would make her a target for the others.
She was fully prepared for that.
On the very next day, Eve woke up at four in the morning and immediately went out to visit the library before going to the training hall.
Since Ophelia gave her permission to visit the library and the training hall, she was going to take advantage of it to gather more information about the Vampire Kingdom.
