Be-reave ～Primary～

A collection of short unrelated H-AVG stories, each drawn by different artists. You start out with 3 stories to choose from. More stories may be unlocked as you complete the stories first available to you. Though the length of each story is pretty short, there are many crossroads to be made that do have an impact on the flow of the story, unlocking various events and scenes and perhaps even multiple endings. There is more to each story than meets the eye. After you complete each story, a green bar will show how much of that story you have covered, giving you an indicator of something you may have missed.
