After failing to establish direct contact through the usage of the user's explosive punch, the chakras that remain within the user's palm can be redirected from their fist into a particular area upon physical contact from a foreign source. If done correctly, this technique can used defensively when that user is either caught or immobilized in any way.
In turn, this technique can create as much damage as the parent technique would and the end result is that unfortunate person is blown up from the inside out if they happen to make physical contact with the user.
