Goryō

is an advancement of the Dark Release kekkei genkai and has only ever been known to have been activated by one person, Kenshi Tachinai.

Overview
The Goryō's most immediately apparent abilities is being able to take advantage of the Dark Release marking of its user, through which it can summon massive earthquakes, typhoons, hurricanes and even firestorms with which to devastate its opponents. The Goryō is manipulated by the hand's of its user which make motions that the Goryō will replicate. Many of its abilities are activated through specific motions as a result. Appearance wise, the Goryō is humanoid-looking, appearing as a large two-armed being with a head that lacks a neck. It is made up of a purple-black energy that makes it very obvious to spot in a crowd. It had two angular yellow eyes and while initially not present the Goryō can form a wide mouth from which it can fire a beam of dark-natured chakra in a single blast or multiple volley.

How the Goryō is formed is unknown but mastery over the Dark Release is a prerequisite for its usage. The Goryō is a very dangerous ability and must be used sparingly in order to avoid killings its user. The rate at which it consumes chakra can be lethal even in short bursts and would leave someone like Kenshi, who was noted to have very high chakra reserves, completely drained if used for any longer than two minutes.

The abilities that the Goryō could grant were dependent on the weapons that it could summon, the primary of these was the, which was summoned when the user clasped one hand over a clenched fist and frew them apart. As Goryō replicates this motion it would form the spear in the space formed between the two hands. The Goryō would cry out the name of the spear upon its completion. With the Tonbogiri in hand, the Goryō is capable of creating dark crescent blades that fire off of the blade in order to attack opponents at a distance. The Nihongo could be summoned alongside the Tonbogiri and allowed the user to make use of the aforementioned elemental techniques, this spear was summoned by drawing the dark release marking across the ground with which the Goryō would trace the motions to summon the spear in mid-air before it. Lastly is the Otegine which was created by clasping the Tonbogiri and Nihongo together (Or in the case of the user, clasping their empty hands together). The two spears fuse into one and allow access to the final technique, the Heaven Splitting Spear, which is accomplished by turning the spear into a javelin in order to devastate the opponent by impaling it then skewering it from the inside out when the spear explodes into dark-natured rods of energy.
