Nisi finally volunteered to take on Charlotte's challenge and vowed to come up with a way to bestow Divine Grace on her behalf before Charlotte fell asleep.
There was no other way, it was necessary for her to take initiative. Being watched by Charlotte's smiling gaze, it truly feared that its "ancestor" might use it as a Divine Artifact.
Nisi firmly promised, and Charlotte was more than pleased to let it be.
Although this sly cat was never serious on regular days, it still was a Legendary Mage who left a remarkable mark in human history and belonged to that small group of Transcendents who understood the power of Gods the best—it possessed exceptional abilities.
Otherwise, it wouldn't have been chased by various churches throughout history for offending the Gods.
Of course, even though Nisi "voluntarily" took on the task, Charlotte was not completely idle.
