i have wonder it said Grayfia Lucifuge once challenge Serafall for the title Leviathan what happen between these two fight and it obvious Serafall win right and get the title Leviathan but if Grayfia lose the fight of title Leviathan to Serafall it obvious that Serafall is stronger than Grayfia but Serafall think Gabriel as her biggest rival basically that Gabriel is stronger or equal to Serafall like just one of the Four Great Satans could destroy the nation of Japan several times over with their power the same to Four Great Seraphs so basically four great seraph is equal to four great satan.
