Patreon Commission - Bimbo Yugiri (Zombieland) (Patreon)

From Zombieland Saga - This is a 3 parter, with the other parts in the attachment. 

Basically the idea is that zombie are unchanging. So while the zombie girls won't suffer from aging, they won't grow anymore than their original bimbo stage. 

However the idea here is that idols lift others up with their performance. So while the zombie idols don't change, their fans do, with every show.
