Shizen Martial Arts Family

A pair of martial arts, both giving their users supernatural abilties. Ten no Shizen is the stronger of the two, but also the more physically demanding and dangerous. Meanwhile, Sekai no Shizen is the more versatile, with four forms versus the former's two. They are often abbreviated in conversation as TnS and SnS, respectively.
Each form in the set is named after a relevant Ancient Earth god of the corresponding element.
Beginning practitioners often need to shout out the form number and name while performing the action in order to help them focus and remember their training, but it’s not strictly required. Experienced users will sometimes continue this verbal reminder in some or all situations. The posing of the body, combined with the mental switch to a new form, are necessary to activate the ability however.

Ten no Shizen

TnS has two forms:

Ereshkigal

Named after the Mesopotamian goddess of darkness, this form allows the user to become wisps of darkness itself. To activate, the user spreads their arms straight out to their sides, with their palms facing downward. Upon activation, the user is surrounded by a deep black aura. In this form, they have zero mass, becoming intangible if they desire. When intangible, physical objects move through them, briefly turning their body into a black smoke.

Belisama

Named after the Celtic goddess of light, this form allows the user to become photons of light itself. To activate, the user raises their hands up to the sky, palms inward. Upon activation, the user is surrounded by a bright white aura. In this form, they can move at the speed of light.


This technique gives incredible power, allowing the user multiple immunities. Most elemental attacks can be negated, and transparent barriers or windows can be passed through with little effort. While active, only light, dark, and one other elemental type attack can damage the user. Ereshkigal darkness can have pieces blown off by wind attacks, and Balisama photons can be diverted with gravity attacks.

However, this technique also has a major drawback: while in use, the user's body is made of photons, which must be maintained in a careful arrangement. Mirrors and other well-polished reflective surfaces can disrupt this delicate setup, scattering the photons and potentially ripping the user apart regardless of which form the user is in. It takes constant deliberate practice to be able to maintain this form for any length of time, often requiring multiple hours every day.

Sekai no Shizen

SnS has four forms:

Pariacaca

Named after the Incan god of water, this form gives the user the ability to dodge all attacks, warping their body to avoid damage. However, this form also prevents the user from interacting with objects or opponents, and they cannot attack in this form. To activate, the user places their arms straight along their side, and upon activation they gain a deep blue aura.

Geb

Named after the Egyptian god of earth, this form gives the user immunity to all physical attacks. However, this turns the body stiff, and prevents the user from moving their lower body. To activate, the user crosses their arms across their chest in an X, fist clenched, and upon activation they gain a brown aura.

Ehecatl

Named after the Aztec god of wind, this form allows the user to move at speeds approaching mach three. However, their body becomes fragile, and attacks that land do more damage than they otherwise would. To activate, the user stretches their arms in front of their body with their palms up, and upon activation they gain a yellow aura.

Kagu-tsuchi

Named after the Shinto god of fire, this form gives the user superhuman strength, allowing them to lift vehicles or rip through thick steel with their bare hands. However, it requires a lot of energy to maintain, depleting the user's stamina quickly while active. To activate, the user claps their hands in front of their chest with their elbows out, and upon activation they gain a deep red aura.
