These are the various clubs that students can join. The clubs are a association of people united by a common interest or goal. It's a way for the player to gain certain advantages and so they can easily access certain supplies. Students at Akademi High School that are members of a specific club or profession will go to their club after school.
Clubs that appear in Yandere Simulator will be listed here. They can be joined in-game, and they all offer different possibilities to the player.
Clubs that doesn't (and will probably never) appear in-game will be listed here. They can't be joined by the player in-game, but OCs can join them.
