After forming the necessary hand seals the user gathers dark chakra in their lungs and superheats it to create black flames. The created flames are then expelled from the lungs and out the mouth in the form of a large stream of black-colored fire. Any flame that comes touches the stream is absorbed to increase the power and size of the stream. When it comes touches the user's target the stream will engulf the opponent in black-colored flames, absorbing a bit of their chakra and creating a crater beneath them as they are burned in proportion to the amount of dark chakra that was used. Like the technique's counterpart, the power and size of the stream can be changed by changing the amount of dark chakra that is used.
