Transcendency (ちょうえつ Chouetsu) is an application of Busoshoku Haki that was invented and then popularized by Satsujinki of all people. It consists of forgoing the imbuement of the exterior of one's body in favor of the imbuement of the interior of one's body, a supermajority of one's musculoskeletal system to be precise. The resultant hardening of one's muscles will augment their compressive strength to the point where their every movement will be several times more energetic than they were before the occurrence of the hardening; however, it should be noted that the inexperienced will suffer from an encumbrance that'll hinder their overall maneuverability.
