Koukou Gurashi was the title of the game from V0.16 to V0.27. Prior to V0.28, the school was a high-school hence Shiro's Highschool Crisis Impact! and Koukou Gurashi having high-school in their titles.

V0.28 was when the game became known as Daigaku Gurashi. The students were remodeled, aged up, no longer wore uniforms, the school became a daigaku (meaning a post-secondary school), and many other changes.

Daigaku change reasons

A summarization of the officially-stated reasons for the "daigaku change" are:

• To be less cliché. Highschool is a very common setting for anything anime-themed.
• To eliminate the confusion and "creepiness" of the students' being potentially younger than 18 since a Japanese high-school typically has Grades 10-12.
• To allow for characters to wear whatever they want as many Japanese post-secondary schools don't have uniforms.
• To have the game be less about schoolwork.
• Having all the students be adults allows for more intimate relationship stuff to be explored.
• To have the game be more relatable to the target audience.
• To make more sense for the player character to live alone.
