Is there some type of power scale you used for the power level? I'm curious how one would even come up with numbers in a story like DxD. Even letter classing (F to S class) would be a little spotty considering we have OP beings like Sirzechs, Ajuka, Ophis, Great Red, Trihexa, and various mythological Gods.
