Why does Ban call Hawk "Master?" Is Ban just trolling or is there some hidden meaning behind that?
Hawk is The Great Leftovers Knight. And at the party when Ban first joined, Hawk rams Ban and said "respect the The Great Leftover Knight". And Ban said (I think) "I'm sorry for not recognizing you, master". It's like when you're good at something, and I admire you and call you master.
