we can take on the world by @nereid (Kim Aberasturi Chua)

Twin sister and brother, Nelris and Neren. Similar to the other pic of the two of them, also in this gallery somewhere. Nelris is the more serious of the two, and would normally not appear as...outwardly confident. But together they'll make it through anything. They get along much better than their younger pair of twin siblings.

Um, that's supposed represent "water" and "air" by the way. Not "blue fire" and "random tendrils." XD
