Phantasy Star II Text Adventures were a series of eight text adventure videogames available to users of Sega Meganet, a modem for the Sega Mega Drive in Japan, and later released as part of two compilations on the Sega Mega-CD. Each of the games takes place shortly before Phantasy Star II, documenting the backgrounds of its characters, and explaining what brings them to the town Paseo where they eventually team up to investigate the pervasive troubles of the Algol Solar System.

Rolf (Japanese: ユーシス (Yūshisu or Eusis)) is a government agent working out of the town of Paseo on Motavia, and the main character of Phantasy Star II. While on a mission, he rescues a young Numan girl named Nei from the Biosystems Lab.
