Myaku

Myaku (脈) is an advanced technique of the that makes use of their vibration-producing skills.

Description
Myaku is a technique which, at its basis, induces vibrations across the whole body simultaneously rather than at a single limb. It is a great skill among those who practice Hasshōken, for it is capable of overcoming virtually any obstacle that a practitioner faces. To invoke Myaku, the practitioner must first take a deep breath. In doing so, they saturate their body with oxygenated blood, which gives rise to an immediate reservoir of power. Subsequently they control the force produced by the tightening and release of their muscles — the source of their vibrations — in every individual muscle in the body, which results in a cumulative vibration from all angles that blasts any enemy in their immediate vicinity.

This technique can further be enhanced with shrouding the force produced by these vibrations, making it a potent technique against  users as well.
