Natsuiro High School: Seishun Hakusho

Natsuiro High School: Seishun Hakusho is a Japanese open-world adventure game set during the heat of summertime. The player takes on the role of Natsuo Aoharu, a student who has recently transferred to a high school on the Japanese island of Yumegashima. He joins the school's journalism club after being pressured to by his childhood friend, Megu Mikazuki, and as such has a camera that he can use to investigate interesting events around the island or just plain get into mischief.

The game progresses in increments of days. The player starts at the high school on each weekday, but can freely explore the island after school, triggering events and accepting quests as they please. There is no school on the weekends, giving the player more time and more destinations to explore. The protagonist's camera is a central gameplay mechanic; with it, the player can take photos of almost anything for the journalism club, and photos of characters will return their name and characteristics. Acting like a nuisance by bothering people or by taking upskirt photos will eventually draw the attention of the police, who must be avoided in order for the suspicion gauge to clear.

The protagonist has a reputation on the island which improves as he completes quests and helps people but decreases if he is a nuisance. The player also has a favorability rating with each of the potential heroines, which influences the development of the story and eventually determines whether Natsuo ends up in a relationship or as a single man.
