Mara is basically the demon king ruling the sixth heaven, and he's known for exploiting human vices to mess with people. Fans often note his obsession with Shaka Nyorai—centuries back, he couldn't prevent Shaka from achieving enlightenment, which clearly got under his skin. Ever since that failure, Mara's been channeling those intense feelings into shaping the world according to his own vision, using people's weaknesses and desires as his tools.
