An example of an information processing system manages a character-associated parameter associated with each of a plurality of character objects, and a player-associated parameter associated with a player. Further, the information processing system stores an appearance condition associated with each of the plurality of character objects. The information processing system specifies at least one target character object among the plurality of character objects. When the player-associated parameter and the character-associated parameter associated with a target character object satisfy the appearance condition associated with the target character object, the information processing system permits the target character object to appear in a predetermined region in a virtual space.
