Haruka clearly said she was ten years old when she introduced herself in the first AG episode. However, we don't know how much time's passed in AG, so we can only assume she's still ten. Kasumi, however, has never said her age.ash_misty4ever said:We don't know May or Misty's age, all we can do is speculate. And, their bodies are different, because they are different people, and the Hoenn episodes are more technologized! :)
