Levels And Tiers

The power of a Skill can be determined with levels of power within it. This power can range from a 0.0 as the lowest and a 5.0 as the highest. These levels are also categorized in tiers from F through SSS.

Tiers
"Note: All percentages are rough estimations."

SSS - 5.0+
There have been no confirmed cases of people with a power level of 5.0 or more, the highest level recorded is a 4.89 although it hasn't been updated in years. (0.0000001%)

SS - 4.5+
Those with a level of 4.5 or above are considered the most powerful, and are also part of the top 10 ranking in the country, with 9 of them being SS. (0.0001%)

S - 4.0+
Those with a level of 4.0 or above are powerful people who have almost mastered their skill, it is very uncommon to come across someone with an S tier ranking. (0.01%)

A - 3.5+
Those with a level of 3.5 or above are known as elites, and are mostly the ones who cause a lot of fights in the world. (0.2%)

B - 3.0+
Those with a level of 3.0 or above are pretty skilled users, most people on this level are either elites in a young age, or a fully developed person. (5%)

C - 2.0+
This is the most common level most users have, especially at a young age. They have some power but don't compare to those above them. (75%)

D - 1.0+
It is uncommon to find users with a low level, those with a level of 1.0 or above are usually hiding and try to avoid fights or crowds. (13%)

F - 0.9>
It is very uncommon to find user with a very low level of 0.9 or less. These people are known a outcasts and are treated terribly in society. (5.5%)

Powerless - 0.0
There has only been a few confirmed cases of powerless users, powerless people are usually always never seen. (0.000001%)

N/A - Unconfirmed
This is for people that were seen in the comic with no confirmed level.

The Grand Tier
The Grand Tier (or known as SSS tier) is when a user's level is over 5.0, the highest level that is recorded. Nobody is able to pass this level due to the limit of the human body, those who can break their limit barrier can advance to skill even higher, maybe even over level 100.0 (which in this level the user can destroy an entire town in one attack).

Human Limits and Awakenings
Skills are powers that can be mastered and have catastrophic levels of power. Unfortunately, the human body isn't able to use even 10/1000th of the power without breaking down. (Level can go as far from 0 to 1000) The only way to surpass the limit is to destroy it or make the threshold bigger, mostly done by the skill itself. Those who are able to get past the 5.0 limit are known to have Awakened their true potential, giving them the name "The Awakened".
