01. Do not consider these power levels official as they are only my personal headcannon. You are free to use them, but better not use them in an argument since you and i could be called liars and idiots.

02. The categories do not state all the characters and species in DxD but rather those who people are familiar with and know the full extend of their powers.

03. Extraordinary characters who for example publicly are only called Low-Class Devils or Average Gods are excluded due to the fact that only the average of such categories are listed.
