Kether

**Kether** (覇権之王(ケテル), *keteru*, lit. "Lord of Hegemony"?) is one of Orochi Yamata's Ultimate Skills and the 1st skill in the sefirot series of Ultimate Skills. It evolved from the Unique Skill Architect and Visionary mixed with a selection of Orochi's Extra and Common Skills conducted by Administrator and the results of spiritual analysis of every Tempest citizens, including Rimuru Tempest and Veldora Tempest.

## Abilities

### Sub-Skills

* *Thought Acceleration* (思考加速 *Shikō Kasoku*)
* *Multi-Dimensional Barrier* (多次元結界 *Tajigen Kekkai*): Absolute defense is achieved through the separation of spatial dimensions, temporal distortions fields, and several powerful barriers around the user, should they be assaulted by an attack they cannot comprehend.
* *Material Domination* (物質支配 *Busshitsu Shihai*): Create and control any substance or entity that possesses mass, also known as matter. Matter can exist in different states, generally through solid, liquid, gas, and plasma. From the orders of magnitude, matter can range from subatomic particles to astronomical scales, such as the observable universe. More specifically, elementary particles, atoms, molecules, cells, microorganisms, animals, buildings, cities, mountains, continents, planets, planetary systems, and galaxies are composed or contain fragments of matter that define it. Because the user can control matter, the user can manipulate nearly "anything" in the universe.
* *Spiritual Domination* (霊的支配 *Reiteki Shihai*): Complete control over souls, the incorporeal and immortal essence of a living thing. Because a person's soul is the root of their life, mind, and skills, by altering the soul, the user can affect any of these aspects of the person, such as controlling others movement, alter their physical characteristics, or even influence the usage and structure of Skills. The user can use this ability to interfere with the Ego, a persons ideology and personality; even a gentle soul who opposes violence can be made into a fanatical supporter of the user who would gladly kill one of their oldest and closest friends
* *Spatial Domination* (空間支配 *Kūkan Shihai*): Interact and manipulate the boundless three-dimensional extent in which objects and events have relative position and direction, within an area of one's choosing, including an area and whatever is inside of that area. They can trap subjects or objects in space and push that space, throwing subject and object away from them or to create wormholes, paradoxes, and other strange events by warping spatial areas and twisting them around.
* *Temporal Modification* (時間制御 *Jikan Seigyo*): Separate the passage of time inside a designated space from the "flow of time" in the outside world. In practice, it can not only 'stagnate the time which has passed' and 'acceleration of time in the future', but also 'invert the passage of time' to reverse cause and effect and changing the past.

### Related Arts

* **Dark Matter** (未元物質, *Migen Busshitsu*, lit. "Unknown Matter"?): Differing from Orochi's usual usage of Material Domination, creating and controlling baryonic matter, Dark Matter utilizes the exotic materials discovered in Deca's studies with the Bifrost. The materials created defies the Laws of Physics, not in the way that magic or skills defies physics, it's just that the origin of these materials are different from the physics of the Central World, allowing him to produce 25,000 different types of energy. It should be noted that the term "Dark Matter" is not to be confused with the true "Dark Matter" which is among the components of the universe.
* **Boundary Dismantling** (原界剥離, **Genkai Hakuri**, lit. "Detachment of the Primitive World"?): Orochi uses Multi-Dimensional Barrier to create a structure that traps the target inside its confines. Using Material Domination, Orochi splits every atom of the targets body, the resulting atomic fission releases an incredible amount of energy that is contained within the structure. The structure then seems to explode with a tremendous amount of force, while the exterior walls of the structure effectively restrict the size of the blast radius, resulting in the destruction of everything and anyone caught within as the very bonds holding together all matter breaks apart, and dissolves matter into nothingness.
* **Idle Manifestation** (無為顕現, **Mui Kengen**, lit. "Manifestation of Nothingness"?): Spritual Domination allows for the **materialization of the soul** (魂の物質化), which stops the inevitable dispersion of the soul once it no longer has an anchor to the world, and essentially makes it transcend to a higher form of existence. It is a magic that realizes true immortality by making the soul into a high-dimensional planar being capable of interacting with the material world as a mental body. The user will acquire an unlimited source of magicules due to the soul becoming analogous to a perpetual motion machine.
* **Distortion Field** (空間歪曲防御領域, **Kūkan Waikyoku Bōgyo Ryōiki**, lit. "Spatial Distortion Defense Field"?): Orochi could cover his body in a spatial distortion by severing the space around him, nullifying all kinds of attacks even the space severing kind. It provides a near absolute defense against physical phenomena, with emission-type attacks that hit it seeming to vanish into thin air.
* **Severed Universe** (斬リ離シタ宇宙, **Kirihanashita Uchū**, lit. Slashing the Universe?): Using Multi-Dimensional Barrier, Orochi creates 3 layers of barrier around the battlefield, with which he could modify entropy within the barrier. By accelerating his own "future" and stagnating the present, Orochi's normal movements appear untraceably fast to his opponents and they appear to move in slow motion from Orochi's perspective. Although he can't utilize actual Time Stop, he could simulate it by reducing time so much to where only objects that could accelerate at 19,037x the speed of light would be able to move inside the barrier.

## Trivia

* Kether is the topmost of the sephirot of the Tree of Life in Kabbalah.
* Since its meaning is "crown", it is interpreted as both the "topmost" of the Sephirot and the "regal crown" of the Sephirot.
* It is between Chokmah and Binah (with Chokmah on the right and Binah on the left), and it sits above Tiferet.
