Ecdysis (слэш)

At the age of ten, Harry was doing pretty well for himself. At school, he was already hailed as a prodigy in the field of science and, though not official, was a blackbelt, if not a master, in at least five martial arts.
Though he couldn’t mold chakra anymore, he had something innate in his bones which reacted to his emotions. Something like magic.
It used to be too thin and fickle before but had grown in strength and potency with his age. Whatever the energy was, it seemed to be maturing with him. So, he nurtured it. He still tried to mold it like chakra from time to time, but his magic was still too weak for that.
//or : Orochimaru gets reincarnated as Harry and decides to blow this flute hard.
