Is there such thing as a SoL/iyashikei/CGDCT school manga where it starts off with a main cast of 3-5 girls, and as time progresses, they gain new younger members, the older members graduate & leave, and it keeps happening until the entire cast is no longer the original?

What usually happens is:
>A) the oldest character graduates and occasionally shows up, but otherwise the story continues in high school with the characters who haven't graduated yet
>B) they all graduate at the same time, and the story ends there
>C) they all graduate at the same time, the setting changes from high school to college, and you catch occasional glimpses of the younger characters doing their thing in high school
>D) nobody graduates, the story continues within high school

Once again, what I'm looking for is:
>older characters graduate (all of them), and they are replaced by younger characters; the story continues with the new cast, with occasional appearances from the alumni

Does this exist? Though I specified manga, I'm also okay with anime, but I assume most anime don't last long enough to go through a whole cast change.
