In reality, the diode is a small metal component, commonly used in electronics to allow single-direction flow to an electric current. It has an input (the positive) and an output (the negative), and its logic gate allows a current to flow from the positive to the negative, but not the other way. In Powder Game, due to the respective properties of thunder and metal, along with the electric misguidance property of thunder-charged metal, it is possible to construct a machine that offers diode characteristics.
