Koukou Gurashi is an anime themed social simulator that includes making friends, enemies, dating, and bullying. The characters are randomly generated at the start, they interact dynamically, and form opinions on each other. You can set out to become the most popular student, play matchmaker, build a harem, spy on people, or just bully everyone.
This game is not suited to the depressed or sensitive. It has some vulgar dialogue and other content that make it not appropriate for a younger audience.
The game has been renamed to "Daigaku Gurashi", and the new wiki is here: https://daigaku-gurashi.fandom.com/
