Pure Stories is a fan disk that complements original Sister Princess visual novel game.
Two visual novels included here are the "Valentine Story", where one story for each of the 12 heroines is available, it acts mostly through reminiscing of past events, with occasional player choices which branch the outcome. The "Christmas Story" acts as a single slightly longer story which starts by the player reading an e-mail from one of the heroines which decides the direction in which the story continues. Additionally, the game includes a town map which lets you visit various locales which advances the time. The map also shows which heroines is at which location which will prompt for a dialogue if you visit a location with someone present. Both visual novels require the player to enter the protagonist's name by which one is addressed to in the stories.
