Harold Jenkins is a character introduced in Chocolatier. He is the chief of the operations in the chocolate factory in San Francisco named Brickhouse Square. He is described by Evangeline as a little deaf, but this doesn't decrease his efficiency on operating the machines.
He has a small role in the plot, only guiding the player in the tutorial. Harold and Stacy Alterna, however, are the only chief operators that appears more in the game.
