Hunting for a date is a strong theme in this game's story.

Nanpa (girl hunting) in Japanese culture is a type of flirting and seduction popular among teenagers and people in their twenties and thirties. When Japanese women pursue men in a fashion similar to nanpa, it is called gyakunan (boyfriend hunting).

In practical VN terms, this usually means that you prowl around the city and meet random girls (or boys), try to chat them up and, if successful, end the encounter with an intercourse.
