"Grade Manifestations" was a group of words that kept appearing. It was often described as a "gift from the Goddess" to those talented. The book mentioned that while those that were able to gain strength were able to obtain it, those talentless struggled.
It was an odd thing to describe. After all, Lua felt that this topic derailed from the main title of the book. While the book did attribute these "Manifestations" to the Goddess, it failed to describe who the Goddess was. Their identity remained a mystery.
The book proceeded to explain that while everyone possessed a manifestation, it never truly appears before Classification 9. After that point, everyone would gain a unique ability that was special to them. This ability would be called a "Grade Manifestation."
