My newest Waifu to add to my collection of Anime crushes is Kuroneko from Oreimo. This is a guilty pleasure anime I accidentally found, and it turned out I really like it. It's totally NOT my usual horror/ supernatural anime, but the comedy and characterization won me over. I just finished the first season of this Anime, and I'm still watching the second season, so don't give away any season 2 spoilers please!
She's a gothic lolita otaku with a knack for cosplay and neko ears. I don't know about you, but they could not have chosen a better character personality for me to fall in love with! Of course she's a bit cold and unemotional in the beginning, but her "dere" side is soooo kawaii!
I mean, look at that shy little blush! Aaaah!
