Liana - Fly girl

Liana is a fly, wich has been flying near all the time, annoying you when you sleep, when you work etc... She is also a one that can become a half human and half fly. "The story is that you hit her when she was annoying you, then she fell on the ground, became half human, then curled up in a ball, trying to hide from you." (You can br anything... I guess?)
