Sento

**Sento** (仙刀, Sage sword) is a special method of fighting and its highest level technique is the sister technique to Jinjin Ittai and Shunko. Considered the ultimate fusion of Kido and Zanjutsu Sento is a high level style which is said only a genius can master.

## ***Overview***

Sento is in principle nothing but Zanjutsu at its core with Kido as a secondary focus but this is a simplification of the style itself, the idea of the method is to increase one's Kido effectiveness by making use of the Zanpakuto, it is in short a method which brings forward the full potential of kido type zanpakuto which tend to be disporportionally weaker at standard Zanjutsu.

## ***Techniques***

Because the use of Sento requires at least an **Intermediate** level at Zanjutsu there are no true Basic Sento techniques. Having higher levels with Kido while useful is not a strict necessity unless you plan to master the style.

### **Intermediate Technique**

* **Kyōryoku Eishō** (協力 詠唱, Cooperative Incantation) - Like the Self-edge Alignment technique this is a cooperative technique for kido type zanpakuto (or others) who wish to assist their wielders. It consists in the zanpakuto performing the chant for the wielder while the wielder does the rest of the kido construction, making it both easier to cast the kido but also faster, with no loss in power and above all it frees up some concentration for the wielder of the Zanpakuto in the fight.
	+ **Kikin Eishō** (寄金 詠唱, Donation Incantation) - A special variation of this technique used by Tomo who has connected her Kidoto to her Zanpakuto Spirit allowing her to make use of the Zanpakuto Spirit's reiryoku as fuel for the casting of Kido, the wielder still performs the molding while the zanpakuto performs the chant but it can theoretically be reversed with the inclusion of the kidoto linkage.
* **Kaihō** (解法, Release Principle) - Less a technique and more a general idea which can be applied to certain zanpakuto, specifically elemental ones, where one synergizes their casting of Kido expediting the process by using the element of a shikai or bankai instead of generating it with the kido casting. An example is using the light generated by a shikai to cast one of many light based kido.

### **Advanced Technique**

* **Jinka** (刃歌, Blade Song) - A special method of Self-edge Alignment where the Zanpakuto will attempt to align their reiatsu with the reiatsu released by the wielder by casting kido, this leads to the phenomenon of **Kyoshin** (共振, Resonance), thus resonating the 2 reiatsus and instantaneously generating a tremendous increase in the power of the kido the wielder uses for a few moments.
* **Jinka** (人歌, Man Song) - A special method of Edge Alignment where a wielder of a Zanpakuto will try to align their reiatsu with the reiatsu released by a Kido-type Zanpakuto when releasing its kido effect, this leads to the phenomenon of **Kyoshin** (共振, Resonance), thus resonating the 2 reiatsus and instantaneously generating a tremendous increase in the power of the kido-effect of the zanpakuto for a few moments.
	+ **Jinka** (忍歌, Patient Song) - A special variation of **Jinka** (人歌, Man Song) usable with melee types, where instead of momentarily increasing the power of a kido effect with Kyoshin they constantly try to align and resonate their reiatsu with the kido effect which provides them a buff, focusing on that alone. The end result is a stronger buff than the zanpakuto could provide by itself.

### **Master Level**

* **Shinshi** (神事, Skill Worthy of the Gods) - A fusion of both versions of **Jinka** where the wielder of the Zanpakuto and the Zanpakuto will both attempt to perform the same casting of the same kido simultaneously, the kido being that of the shikai release, this dual casting if done with perfect alignment of their reiatsu creates **Kyoshin** (共振, Resonance), fusing both castings into one super strengthened effect. A properly performed Shinshi can allow a shikai to clash with and overpower Bankais. This technique is tremendously hard to actually learn much less perform successfully in combat due to the simple fact that the kido that kido-type zanpakuto use is so incredibly complex as to often be nearly impossible to replicate, furthermore Zanpakuto spirits themselves don't fully understand their own ability to perform their kido in the first place making this technique be available only to Zanjutsu AND Kido masters of the highest calibers since the skill required to reverse engineer, cast and synchronize this type of kido is so ridiculously high.
	+ **Ryo Shinshi** (諒神事, True Skill Worthy of the Gods) - The ultimate theoretical version of Shinshi where the Zanpakuto and the Wielder both perform the Kido effect of the Bankai while resonating perfectly. The resulting effect is a Bankai release so tremendously powerful that it dwarfs even a mastered bankai in the sheer power and scale.

## ***Synergistic Kido***

While some of the techniques of the style are able to be used with every Kido spell some of the Advanced Techniques definitely have a type of kido spell which is best suited for use with Sento. The kind of spells which are best to use with Sento are one of the following:

* The Kido creates a projectile that has a relatively simple effect, Jinka is able to speed up these projectiles just before they exit the range of the Zanpakuto's reiatsu.
* The Kido enchants the zanpakuto with some kind of melee useful effect, Kido like Tsuzuri Raiden for example. This allows one to increase the enchantment on the spot without the cost of upcasting, making it more energy efficient to be used in melee.
