Masazo is a quiet and timid architect, but a little greedy. His Stand, Cheap Trick, constantly keeps him afraid, telling Masazo he would die if anyone saw his back.
Masazo is one of the people shot by Yoshihiro Kira to defend Yoshikage Kira. He wasn't aware of his Stand (only what would happen if its ability activated) and didn't want to attack anyone, and so tried to live a normal life with it. He was eventually called by Rohan to evaluate his burned house, and had to turn his back against someone else's and walk backwards to reach the house.
