original: itachi// Nobody cut her hair, that's actually her real hair xD her long hair is actually chakra, she learned from her mother how to control her chakra and save it. This technique has a lot of weak points,it is very hard for the user at the beginning to get used with such a big quantity of chakra and after they get used to it, they can't live without the chakra. When they lose a lot of chakra, just like Ayuuki in this picture, they feel their bodies burning. All in all she's fighting a summoned person, more exactly the one who saved the Misaki clan, Suiren Misaki. She obviously lost and is about to die. v-v ... or not :)
