Origin Release

is the original known as Kekkei Mōra. It was first utilized in the form of the Adorned Branch of Hōrai technique by Kaguya Ōtsutsuki.

Overview
The defining trait of the Kekkei Mōra is that it embodies all of the basic elements — earth, fire, lightning, water, and wind — as well as the elements of yin and yang. Therefore, through the Origin Release, it is possible to passively mix together selective elemental natures in order to yield more advanced natures in accordance with the user's whim. Madara Uchiha, in particular, made use of this method after becoming the Ten-Tails' jinchūriki in order to gain access to the Storm Release. Despite not actually possessing said Kekkei Genkai, he was still able to access it due to the Origin Release.

Trivia
