[HELP]Identify the Games from these Images?

[GerryAtric]

Hey all,
I was wondering if someone could identify the game's titles from just pictures of a heroine? I try google search, but it does not work very well at all. They could also just be artwork, but just in case I ask.
Will also be posting any other images like this in this thread if anymore are found!

Spoiler: Request as of 24/9/16:
