Azai Kyousuke

He constantly pretends to be a selfish, bad person to the point that he even tries to convince himself (and the readers) of that fact, but in reality, he is a rather kind and selfless person, who would literally put everything he has on the line to help others. Even his obsession with money is just due to a massive debt he has to pay back, which he has by no fault of his own. His public demeanor is mostly a show he puts on, and he actually leads a rather humble lifestyle.
