Because you got the death flag from the MC.

Obviously the girls who doesn’t get a collar needs anal. This is the 100% pure logic of this manga.

 

[phoenixir]

I have a theory. All the girls without a collar are candidates for being avatars of the god of deep jealousy. Or the lack thereof represents a different type of dependence

 

[firosahoge]

Pinako can talk to Noa, but Hanahana can't, so I guess Pinako really has the collar but the author keeps forgetting to draw it

This just gets darker and darker
