Suzushiro Nadeshiko

To all those around her, she seems like a ladylike and graceful Ojou-sama type. However, she has an obsession with butts-- both her own, and those of the people around her.

When she was a child, she had fallen ill and her father gave her a suppository. It's for this reason (?) that her ass obsession was awakened...

She buys lots of anal-themed paraphernalia from Aya, and sometimes gets caught up in admiring her collection.
