Bizu's background is unclear, though it can be assumed he suffers from chronic overthinking to the extent he is frequently unable to sleep and feels sick. For emotional release, he seems to enjoy causing trouble and lashing out, differentiating himself from those who respond to their discontentedness by turning to superficial pleasures or even suicide. He seems to have quite the superiority complex, coping with his feelings of inferiority by viewing others as mindless machines.
