The Mysterious Man is a non-player character who appears within the fairytale simulation net of the ComNet, where he works as a performer in a story drama called Sun, Wind and Traveler. His background is that of a digital actor inhabiting that themed virtual space. His personality is suggested by his actions rather than directly shown: he approaches the Corrector program Freeze with a specific request to search for a missing little girl, claiming he wants to return her to safety. He imposes one notable condition on this request, instructing Freeze not to speak about the search with anyone. This condition hints at a secretive or cautious nature, and the request itself indicates a sense of responsibility or connection to the missing child.

His motivation in the story is to locate the lost girl, a task that ties into the larger second-season storyline involving a mysterious virus and the human Corrector Ai. By enlisting Freeze, he sets a chain of events into motion, though he himself remains in the background as an instigator rather than an active participant. His key relationship is with Freeze, to whom he entrusts the search. He also has a connection to the missing little girl, who is central to the plot, but his exact bond to her is not fully elaborated. The Mysterious Man does not undergo significant development across the series; his role is confined to the episode where he makes his request. His notable ability is his awareness of events within the fairytale net and his knowledge of the missing girl, which positions him as a catalyst for the narrative rather than a combatant or a figure with special powers. His function is to present a mystery that drives the actions of other characters.
