Boil Release: Acidic Bomb

Taking inspiration from Naruto's Wind Release: Rasengan, Nakuka create a technique which mixes her own Shape Transformation and Nature Transformation. Because she never learned the Rasengan, she had to shape her chakra with force rather than with control. When her chakra becomes physical, she must hold it in place to ensure it doesn't erupt on her. Then she adds her Boil Release chakra, adding to the severity when contact is made. However, because of her lack of shape transformation control, this severity is not limited to her opponents. The first time Nakuka used this technique, her hands turned out to be burned during the process, so badly so that her skin and meat was completely torn from her hand and wrist. Because of this Tsunade deemed it a forbidden technique.

Nakuka later used this technique upon receiving her Rinnegan, which merely absorbs any chakra that might harm her. However, its status never changes, the risk far too high for any other users to handle.
