Black Diamond

Black Diamond is a 3DCG visual novel by Deus Actum with a female protagonist. It follows Lydia, an 18-year-old about to start her first year at a prestigious college in New York. She has devoted her life to studying and has little experience of the world outside the classroom, so everything about the big-city university is new to her.

The story asks whether the player's choices will improve her life, make it worse, or leave it unchanged. The tags point to corruption as a theme, so the direction she takes depends on the decisions made along the way.
