Sotsugyō Vacation

Sotsugyō Vacation is a love adventure game and part of the Graduation series. It is a sequel to Sotsugyō Crossworld, featuring the cast from that game plus three new characters. The player joins some of their classmates on an island summer vacation; the island turns out to be kind of boring, so after hearing a story about hidden treasure somewhere on the island, some of the girls decide to spend their time looking for that treasure.

Each day is broken up into morning, noon, and afternoon; the player can choose a location to go for each time an potentially meet up with the girls either alone or in a group. The more times you meet a girl, the more your friendship with them progresses and the more events you see with them; each of the 15 love interests has their own events and ending. In the evening during dinner you can also ask around to find out each girl's plans for the next day and where they're planning to search. There are also various mini-games that occur throughout the game.
