It's nice to see some sadodere love, despite Nakamura being the best of the lot I've seen and enjoyed.
I have a strange affection for Nagatoro and find her honourably pretty even when she makes some gross expressions that I no doubt the author is into and her sadistic quantities are toned down in the manga.
Seeing her drop her spaghetti hard when she gets so happy she drops her social mask is priceless.
Bifauxen, orekko and "walk on the wild side" nee-sans are also types I like and I enjoy a good kuudere when she's well written ie Reina. I find their mysterious charm, sleek streamlined looks and quiet passion attractive but feel let down if her trust in other people is "unlocked" by a man and they aren't allowed to do it themselves in letting intimate relationships re-enter their lives.
