Included with the release of Tron ni Kobun, this game is a technical demo that serves as a prelude to Rockman Dash 2: Episode 2 - Ooinaru Isan (Mega Man Legends 2). These four missions precede the events of Episode 2, which made up the entirety of Mega Man Legends 2 for versions outside of Japan, though they are mentioned in the later game's dialogue.
The game story consists of four missions, culminating in the kidnapping of Roll by Tron Bonne (an antagonist in the first game). Rockman must defeat Tron and her henchmen to free Roll.
