Seiryoku

**Seiryoku** (勢力, *Force*) is a fighting style that mixes one's Reiryoku and Hakuda usage to create devastating effects, primarily leaning toward the former's usage. It was created by Daiei Takeuchi when he was still part of the Zaraki-kai.

## Overview

One's Reiryoku is an important aspect for many beings, as it allows them to achieve feats they themselves may be unable to do, or level the playing field if they had the potential to do so. Daiei centralized this concept into a fighting style, as Reiryoku is often used for basic needs, instead of being used for a higher purpose.

Seiryoku was named by Daiei, but many Shinigami, Hollow, among other species, have displayed capabilities of doing Seiryoku, even if it's at a minor level. An example of Seiryoku usage is Kaiyon's expulsion of his Reiryoku and then forming it in front of his mouth to make a Pseudo Cero. The potential of Seiryoku depends on how masterful their control over their Reiryoku, along with their Reiatsu, is.

Daiei equates Seiryoku as your very essence manifested so that you gain more range in your abilities, similarly to how a weapon is an extension of one's body. He further states that mastery of Reiryoku comes with understanding one's self and knowing when to release and hold within their Reiryoku. Daiei considers Reiryoku to be similar to a river's flow eventually returning to the waterfall that it was expelled from, following a cycle that will be followed if you allow it to be. Naturally, Reiryoku is returned to its user over time, especially when Shinigami consume food, but Daiei has taken it to the level that he rarely loses his Reiryoku when using this fighting style, as he has enough of a mastery over it that it cycles back to him when he's done using it.

Reiatsu is often used for simple force, but it has the potential to create devastating effects if controlled properly, something that Daiei capitalized on. However, in his youth, Seiryoku was nothing more than a destructive usage of Reiatsu that had no form of real tact, being considered almost opposite to what Seiryoku is now.

Weaponizing one's Reiryoku leads to Seiryoku, which can achieve feats such as telekinesis, prolonging attacks that should have ended, among movements that would normally be impossible with one's own body.

## Named Techniques

* **Senkai** (旋回, *Gyration*): The formation of this technique takes the form of a concentrated spiral-like ball of Reiryoku within the palm of their hand. So long as the user has control over it, it will continue to spiral quickly upon itself, where in certain instances it becomes faster the more it's active. By placing the attack onto the target, it will decimate the location it's applied to, ripping it apart at exceedingly quick speeds. Masters of this technique can keep the attack active by further concentration, even moving it from its position if they had enough power to do so.

* **Chiratsuki** (ちらつき, *Flicker*): By forming Reiryoku onto their hand, the user can flick their Reiryoku at the target, similarly to a projectile, injuring them. Daiei performs this technique by moving his hand back at a peculiar angle, and then flicking it quickly at the target.

* **Yoshin** (余震, *Aftershock*): After performing a Hakuda technique, be it kneeing a target, kicking, punching or otherwise, the user channels their Reiryoku, turning it into Reiatsu, to simulate the technique that was performed, thus making another attack without the need of extra movement.
	+ **Mugen Yoshin** (無限余震, *Infinite Aftershock*): Similar in principle to Yoshin, it is a Yoshin of a higher level. After Daiei has simulated the attack, he manipulates the Reiatsu to continue to simulate the attack, as though the target is being attacked infinitely. Because it does not require any further Reiryoku to be applied to the target, Daiei wastes no further Reiryoku when performing the technique, instead simply needing concentration.

* **Miburui** (身震い, *Trembling*): By striking someone in the abdomen with the back of their hand, the user releases their Reiryoku from the impact to send a shockwave through the opponent's body to cease their motor functions temporarily.
