Akira always acts professional while she's working and does whatever she can to not waste time so she can complete her goal to exterminate all ghouls. She also had a deep admiration for her father as she thinks that he was doing good by killing all ghouls but failed to realize that he was just an insane psychopath who just wanted to retain his bloodlust.
While she may seem homicidal, she does have actually emotions as she eventually fell in love with Koutarou Amon even after blaming him for her father's death. These feelings were shown further when she was mourning after Amon and Takizawa's apparent deaths and still didn't get over it after two years later.
