#xepias

Xerry has 3 arms and 1 leg... get it? hehe, those things are called Xepias, they are like two big hands with their own consciousness but connected to Xerry's own mind (as if it was another head). Each Xepia has different functions, Xerry can fly thanks to hers (yep, they also work as wings). She is not the only one with Xepias. But I don't want to make a wikipedia explaining this, more info will come out little by little hehe.
