The user uses shape and change in chakra to create a long whip made of nothing but flames. The users hand becomes covered in flames and that is where the whip comes from. The whip is able to extend but that and how hot the jutsu is depends on the skill of the user. I can also be used as a rope to grab and swing from things and the end of the whip looks like a dragons head. The must have good control over their chakra to perform this technique without hurting themselves.
