An information processing system includes a controller which receives an operation input of a user and an information processing unit which performs an information process based on the operation input received by the controller. The information processing unit includes a game progress unit which controls an own character in the virtual space based on the operation input of the user to draw the virtual space with the corresponding color of the own character and a battle determination unit which performs a battle determination based on a drawing state of a corresponding color of an enemy character, which is different from the corresponding color of the own character, to a virtual space and a drawing state of the corresponding color of the own character to the virtual space.
