Harry Potter is the main one but I love anime, too, so Kuroko no Basuke, Yuri on Ice, Fruits Basket, Kamisama Kiss, Black Butler and others. I also love the Avengers and DC. I don't have a special interest other than reading and writing fanfics so I'm not sure if that is a special interest or just a regular hobby but I've had special interests before and my love of anime has lead me to remembering Japanese honourifics, traditions, and learning to make sushi. Weeaboo or special interest, I don't know.
