Happy, Lucy Heartfilia and Natsu Dragneel.
Fairy Tail. Lucy and Natsu (NaLu). Part 1.
Lucy Heartfilia- Fairy Tale - Planning to debut this cosplay for Anime Weekend Atlanta 2012!
Swine creature. Girl with fox ears and can turn into fox. (maybe Mariposa's hair can change color)
I don't know what they are, but I like their elf ears and her outfit.
