An Inner Power technique in which the practitioner circulates Ki through his body, and releases it through his fist at the same time he extends his hand. The Ki circulation must be properly timed or the attack will fail and the user will feel the burn of improperly released Ki on their fist. Requires large reserves of Ki for extended use and the ability to synchronize the release of Ki with the movement of the body. Ranma can throw several hundred punches so swiftly that it looks like a single strike making this an exceptionally powerful attack. This technique can be recognized by the sonic boom it makes when used.
