Technique - Devas (Caution! Contains Spoilers!)

Sun Breathing (Devas):

First form: "Solar Flare" - The user rotates the lower part of the body slightly to the left while turning the upper part of the body slightly to the right, thrusting the weapon forward in a single stab, releasing all the force of the strike in a single moment.

Second form: "Static Rotation" - The user fixes the lower part of the body to the ground and wields the weapon with both hands, making a horizontal strike across the entire frontal area, using the full force of the body.

Third form: "Binary Stellar System" - The user unleashes two strikes around their own body, fixing the wrist on the first strike and using the surplus force, rotating the wrist for the second strike.

Fourth form: "Magnetic Field" - The user rotates the axis of the weapon in front of their body, creating a spiral that extends to defend against frontal and diagonal attacks.

Fifth form: "Solar Feint" - The user leans backward while simultaneously striking forward at rapid speed, creating an illusion that the strike does not have enough reach to hit the enemy, aiming to decapitate them.

Sixth form: "Solar Veil" - The user strikes forward in a simple motion, with the wind around the strike enveloping the weapon, making it momentarily invisible due to the refraction of sunlight.

Seventh form: "Dawn" - The user tilts their body forward while propelling themselves, quickly striking upward in a single swift movement.

Eighth form: "Solar Rupture" - The user holds the weapon with both hands while twisting their arms in a simple strike, aiming to hit only the tip of the weapon in a quick thrust that generates a shockwave hitting the inner part of the enemy, breaking their defenses.

Ninth form: "Dance of Solar Shadows" - The user strikes forward rapidly in sequence, taking a step for each blow, creating an illusion of multiple shadows of the same person attacking alongside them.

Tenth form: "Diagonal Eclipse" - The user uses their feet to propel themselves forward diagonally towards the enemy, exploiting their blind spot while simultaneously rotating the body, attacking the target from behind or the flank with the intention of splitting them in half.

Eleventh form: "Mirage" - The user quickly kicks the ground while giving a small leap backward, jumping almost parallel to the ground, leaving a residual image where they were previously to confuse the enemy.

Twelfth form: "Solar Reversal" - The user delivers a combo of two strikes, the first being a rapid strike from above, which, upon reaching the end, the user spins their arms and wrist, conserving the acceleration and force of the first strike to unleash a second strike from below almost instantly.

Thirteenth form: [ERROR - REDACTED]

Thirteenth form: (拾じゅう参さんノ型かた Jū San no kata) - The user continuously performs all twelve forms of Sun Breathing in repetitive succession to increase the accuracy and agility of its movements, and attacks.
