Headscratchers / AR∀GO: City of London Police's Special Crimes Investigator

• Okay, so we're told that Albion has existed for centuries and have been guarding England from the supernaturals ever since it was created. But where exactly was Oz in the beginning of the manga? I mean THAT has to be a big deal, right? Arago had half of Brionac and greatly weakened Patchman. I get that he had other things to do, but don't you think that Patchman is a bigger problem? Why not help Arago out?\
