It is very likely that Ringo Akagi is one of the most powerful characters in the greater BB/XB franchise, and almost certain that she's one of the most knowledgeable about the greater magics of her world.
As a member of the Mercury family and the Ten Sages, her magical abilities and know-how must be on the same level as Nine's.
Additionally, she's implied to be one of the greatest members of the Sages, as when she left the organization, they reserved her seat for her; in hopes of her return, and in acknowledgement that she could not be replaced.
The only other character to be granted this honor is Relius Clover in his tenure as One.
