He just saved a whole district of the capital and how do the previously long-suffering, now saved folks there thank him? By calling him using insulting nicknames. Like how the heck could that ever happen? This is the pitiful epitome of the author's sense of humour, and thus the author keeps repeating the same idiotic joke endlessly every chance he gets. This is what happens when the system has no editors or, like the author of Sono Bisque Doll puts it: if the only things the editors ever request from the author are cute girls, romcom, and panty shots. A genuinely talented author can still deal with it, especially if they happen to have some family or friends who could check the script, but the author of this Seija Musou neither has talent nor anyone who would tell him he keeps writing bullshit.
