When you get a new girl. Typically there are three stages of unlocking. The scenes are hot typically with a girl slowly undressing. There's no option to "Go Back" look at the artwork in differnt stages of undress. Why not make an album people can use that has saved pictures of the girls from first stage of undress to the last. We usually can play the game again. However there's no method for looking at Harem girls when you first unlock it.
