I also don't get the D-rank and B-rank shit. They have seen, that MC is strong. If they would care so much about ranks, shouldn't they have endorsed a rule like, that people with ranks that differ 2 ranks can't have a duel?
Isn't it also courtesy, that the accepting party chooses the weapons and the other the date? As it seems to be an all-allowed kind of duel, MC should have at least be the one setting the date, not the challenger. "I challenge you to a duel. Pick it up or I rape your wife, daughter, uncle or dog, depending on which chance arrives first. ... Fine, now that you picked it up and as I see you happen to not wear your armor, nor carry a weapon at the moment and in regard, that I just happen to have spiked your last drink, I say we duel right... NOOOOOW!!!!!!!!!!!!!" That sucks. XD
But those duel rules could also be quiet neat. In MCs stead I might have challenged all a-holes I can muster and this includes county officals I want to see gone. I would have gone to them and told them, that I didn't know the meaning of picking the glove up and him being a B-rank and me a D-rank. if they laugh me off I challenge them myself and set the date AFTER my duel with the douch. Right after it! I would challenge them in a ridiculing way, that leaves them with their honor, if they accept on the spot. All in hope they accept, because >I wouldn't be around then anymore anyway<. Then I invite them to watch the first duel.
