This is a dream creature for a project called Lucid Dreamers, a story concept inspired by pokemon and Kingdom hearts elements.
This girls is named Yume (she was originally Clefairy in my fanfic for pokemon). Her species are known as Clorofae, a flower fairy race that harnesses light for sustenance and power. In particular, Yume's base attributes are plant and light based. (Phyto/lustro)
