in Volume 6 when the nun rapist was working with the old saten faction CB Sirzechs was fighting them he was able to easily overwell a line from the old four satans which they said had Maou class strenght without even going into his true form and using just a little bit of power which if you look at it this would back up my saying that Sirzechs was around twenty time Diehauser power when in his true form and Diehauser was about1/4-1/2 of sirzechs power when he is in his normal form. If you think about it how would the four satans deal with ulitmate level devils if they couldnt fight them and beat them even if they had the same level as a maou.
