Shoujo no Michikusa ~Houkago Ura Club~

The girl I have an eye on... Whom does she like!? The manager of the baseball club is a girl named Saki. She's cheerful and works hard, and everybody loves her. You take pains to get time alone with Saki, earning points with her by helping her out. And at last, you get to find out who it is that she likes! Who could it be? The core of this game is the "true route", but there are also other routes such as the "abuse route" where you get the opportunity to defile Saki.
