The ring is just a gift you give to a heroine after giving back their underwear. It gives some new dialogue when deciding to talk to that person. It does not affect any endings, to my knowledge. I've tried it myself. Renka is something supernatural, possibly a succubus. There's a bit of lore about her that you can find in the library within the last dream, but it's mostly about how things like common sense are alien to her, like having to read books to make friends with other girls.
