St. Luminous Mission High School (Sei Luminus Jogakuin)

With the exception of the real-time adventure portion, this game implements an SSS (Synchronized Security System) which allows the player to pick up students' conversations through a device set up inside the school. In SSS mode, if you find a subject that seems useful for chatting a girl up, you can hold onto it in the form of a card so that when you meet her, you can bring up the topic of your choice.
