Haki

Haki (覇気) is an Extra Skill and the evolution of the Common Skill/Intrinsic Skill, Coercion.

Effects
It allows the user's aura to exert spiritual pressure over targets in the surrounding area, freezing their body in place and bending them to the user's will. The only way to overcome this without exerting a Haki of one's own, is through sheer willpower.
