Gensou Suiko Gaiden Vol. 2: Crystal Valley no Kettou

This is a side story to Konami’s RPG series Suikoden. The events of the game
take place between the second and the upcoming third game, and fill the story
gap between them. The story centers on the rebellion that has taken place in
the Grasslands. It has been three months since the end of the Dunan
Unification Wars. A legend telling about the Fire Brigands lead by the
mysterious Fire Champion who united the Grassland nations is being spread
around. Is the legend true, and can the Fire Champion, a holder of one of the
27 True Runes, be found? Nash, a special agent of Holy Kingdom of Harmonia’s
Southern Fringe Security Force, is sent to investigate the matter.

You take control over Nash’ actions in a fashion similar to the one
implemented in Japanese “dating sims” or some hentai games: reading the text,
looking at the background images, and sometimes interfering and choosing the
path on which the story should proceed.
