Main Character - SPOILERS

[There are six main ranks for physical and mystical quality. Considering F rank to be a normal value for an average human. E rank is equal to ten times the normal value and it increases by ten incrementally until reaching fifty times at A rank. A rank is the highest normal rank, but there is an exception to the rule with the EX rank. It represents something that falls outside of the numerical ranking scale, a value that cannot be evaluated under the normal system because it is in a league of its own. EX rank is too powerful to the extent of rendering comparisons meaningless. The "+" modifier shows an increase in quality. The "-" modifier shows a decrease in quality.]
