Kaiyon

**Kaiyon** (カイヨン, *Kaiyon*), lesser known as **Kaiyon Greej**, or to certain people as **Kaiyon Tsunayashiro**, was a student within Shin'ō Academy as one of the members of the infamous **Class 4**. Initially born within the 63rd Southern Rukongai District **Greej**, he, as his original persona, was eventually sold into an orphanage controlled by **Den Mother**. After breaking out and usurping control over the body as the newly dominant personality, Kaiyon lived his life alone. Since his birth, Kaiyon has held an extremely potent, yet uncontrolled, Reiatsu, allowing for him to survive against those that may want to kill him, but in turn killed those he tried to form a bond with, such as when he instinctively entered his **Predator State**.

At an unknown age, he was adopted by a traveling old man that made him into a servant of the Tsunayashiro Family. Within the **Forlorn Souls Arc**, it was found out that Kaiyon was mistaken about being a servant of the Tsunayashiro Family, and instead adopted into it as Hakuchi's son. It was due to his time within the orphanage that his instincts took over and assumed the position of a servant, not understanding the concept of affection from parents.

Prior to becoming who he is now, he was an Arrancar that went by the name Estrellatu. Through Estrellatu's curiosity, the Arrancar accidentally performed suicide on himself via ripping off his entire Hollow Mask, which resulting in his death diverting from the logic within the cycle of reincarnation, thus creating the Neo now known as **Kaiyon**.

Kaiyon is one of the main protagonists of Stained.

## Powers & Abilities

* **Life Link**: Kaiyon shares a unique experience with his original personality, whom he has named **Yonkai**, who acts similarly to the concept of a Neo's **Laulā**. In this case, Kaiyon and Yonkai can, essentially, gain each others' experiences and apply it to the other without any issue. Through the efforts of the Hōgyoku within the **Forlorn Souls Arc**, they split, but still remain tied to the same Soul. So, if one were to die, the other would be absorbed back into the active one's Soul. Through this Life Link, Kaiyon and Yonkai are able to learn things at twice the rate of an average person, but they still suffer from their own rate of learning.

* **Enhanced Strength**: No matter Kaiyon's particular mental state, he has always shown to boast a tremendous amount of physical strength, fitting his stature, that has allowed him to perform feats that most of his classmates cannot do at a base. During the first part of the **Minashi Arc**, Kaiyon, within his **Predator State**, was able to use a pillar as a baseball bat against the Wolf Minashi without any hindrance to his movement.

* **Enhanced Speed**: At the beginning of Stained, Kaiyon was unable to use Shunpo, and continued to have difficulties in understanding its concept. However, despite the lack of this particular Shinigami technique, he was initially shown to keep up with his more faster classmates, such as Knave and Toko, and even going further in surpassing them in speed when they were competing within the first part of the **Minashi Arc**, despite still being within the start of the race. As the story went on, Kaiyon became a faster and faster individual. Within the **Forlorn Souls Arc**, he was shown to be able to keep up with average Shunpo Experts through his speed alone.

* **Supertaster**: Kaiyon's taste buds are of a higher level than most beings, allowing for him to taste things that normal people would not be able to. Because of his Mea'ai, this is especially helpful to him, as it would allow him to replicate certain things that wouldn't normally be classified as "food".

### Reiryoku/Reiatsu

Kaiyon, ever since his birth, has always had a higher than average level of Reiryoku at his disposal. In the beginning of Stained, Kaiyon's Reiryoku was on the level of an **Averagely-High** Soul, which was in between an **Average level** Reiryoku, something that was reserved for seated members of the Gotei 13, and a **High level** Reiryoku, which is something typically reserved for those of a Lieutenant-leveled Shinigami.

Sometime during the Shambled Society Arc, Kaiyon's maximum Reiryoku was fully elevated to the level of **High** thanks to his mentor, Yakitori Yasuyoshi. During his battle against Beberos within their connected Inner Worlds, which happened within the second part of the **Minashi Arc**, Kaiyon displayed that his maximum output was raised from High to a level between High and **Great**, the latter being an output usually reserved for Captains. It wasn't until the **Forlorn Souls Arc** did Kaiyon gain the Reiatsu signature of a Captain, being elevated to a **Great Spiritual Power**.

Initially, Kaiyon had little to no control over his own Reiatsu, which often led for it to constantly leak out of his body. Whenever Kaiyon entered his **Predator State**, his Reiatsu would burst at the seams, leaking at a rapidly uncontrolled rate, resulting in him losing his stamina faster, but made him a powerhouse compared to the rest of Class 4. Within the **Shambled Society Arc**, Kaiyon displayed that he was able to go to the level of an average **8th Seat** without any hindrance to him. However, during his fight within Ichimaru Ketsuno, he elevated himself to the level of an average **7th Seat**, but lost control over himself due to him staying under that level for too long.

During their time within **Minashi** for seven years for the **Forlorn Souls Arc**, Kaiyon, excluding his mental fortitude, primarily focused on his Reiatsu control, which then allowed him to control up to the level of an average **3rd Seat** without any form of hindrance.

Kaiyon seems to possess a pink Dual-type Reiatsu signature, primarily giving off the presence of a Plus, but has been noted to have a hint of Hollow in it, something that Toko picked up before.

* Seiryoku: Within Minashi, Kaiyon was taught in the art of Seiryoku. However, his capabilities after their seven year timespan finished was minuscule, only able to concentrate his Reiryoku in a similar manner that he had been doing with Mea'ai, even if it was instinctual.

* Shinnoden: Kaiyon was shown to have gained Shinnoden like his other classmates, but has not been shown using it since.

### Hakuda

Since the beginning of Stained, Kaiyon's primary form of fighting relied on abusing his Mea'ai in conjunction with hand-to-hand tactics. Along with Zanjutsu, Kaiyon learned Hakuda from his mentor, the Old Man. It was through his teachings of Ryōdan that Kaiyon was able to learn more abilities from this, such as **Ryōdan-ken**, which is the Hakuda variation of Ryōdan-ryu. As of the **Forlorn Souls Arc**, Kaiyon could be classified as a **Hakuda Expert**.

### Zanjutsu

Though it was Kaiyon that learned Zanjutsu through the Old Man, Kaiyon and Yonkai saw it best to primarily split the two fighting styles between both of them, seeing as Zanjutsu was a more forceful type of fighting style that fit Yonkai better. Despite this, they are both still classified as **Zanjutsu Experts** as of the **Forlorn Souls Arc**.

### Hoho

Kaiyon's knowledge of Hohō during and prior to the **Forlorn Souls Arc** was relatively low, as he didn't acquire even the basic knowledge to use Shunpo prior to the arc. However, as of this time, he is only seen as a practitioner, and fails in comparison to his own speed.

### Casting

#### Kidō

Kidō is the second most difficult Shinigami style that Kaiyon has had to face, as he primarily kept his focus on using Hadō #1 Shō for quicker movements, such as trying to bootleg Shunpo. Because of the seven year timeskip within the **Forlorn Souls Arc**, Kaiyon's knowledge of Kidō was elevated, thanks to the teachers present, along with the book that Tomo made for him and Ichimaru Ketsuno, giving him the ability to go up to level 29 Kidō spells, but still struggled with Kidō above level 18.

* **Hadō #1** Shō: Shō was one of the most utilized spells for Class 4 near the beginning of their time. For Kaiyon's purposes, he primarily used it as a means of making himself faster in quick bursts.

* **Kaidō Practitioner**: Because of Yakitori Yasuyoshi, Kaiyon was taught the basics of Kaidō. However, he has not been shown to actually be able to perform it, and instead can only give away his own Reiryoku, instead of mending someone's Reiatsu and wounds.

### Racial Abilities

As a Neo, Kaiyon could also technically be considered an Arrancar because of his past life, Estrellatu. Not only is Kaiyon able to gain access to Neo capabilities, but he is able to gain access to Shinigami and Hollow abilities and making them his own. However, since he is a Neo, most of these potential abilities come with a general condition that he bond with his **Laulā**, which he holds two of, one that is a **Hollow**, while the other is akin to a **Shinigami**.

* Cero:
	+ **Pseudo Cero**: The concept of a Pseudo Cero was something that Kaiyon came up with instinctively, generally when he was within his **Predator State**. By manipulating the Reiryoku that leaked out of his body, he concentrated it in front of his mouth and shot it at enemies.

* Hierro: Because he was an Arrancar in his past life, Kaiyon is able to use Hierro. However, because he lacked proper knowledge of his Neo capabilities, his body instinctively provides him with a Hierro.

#### Huaʻi

As with all Neo, Kaiyon gains a **Hua'i**, which he has dubbed as **Mea'ai**. By the utilization of his Reiryoku as a base, Kaiyon is able to manipulate, and subsequently shape, it in whatever way he wants in the form of food for its appearance. This ability was unlocked to him when Yonkai was still the original personality and found refugee in the food given to him in the orphanage, the only thing that really made him happy, and as such was something he constantly looked forward to. With this, his love of food became his Hua'i.

* **Mea'ai Whip**: Though Kaiyon is normally seen to use caramel as the whip's foundation, he has shown to use other substances, such as cream. This whip generally allows him to hook himself to locations faster.

## Yonkai

**Yonkai** (ヨンカイ, *Yonkai*) is the original personality of Kaiyon that was manifested via the incomplete Hōgyoku's influence. As the original personality, he was the one that was reincarnated from Estrellatu, along with being the originator of a favored ability of Kaiyon known as **Mea'ai**.

After his breakdown when he escaped the orphanage in Greej, Yonkai passed out. Upon his awakening, he found out he was no longer the dominant personality in the body, which resulted in Kaiyon's creation. Unfortunately, during this shift, Kaiyon subconsciously sealed away Yonkai within the recesses of his mind, only being able to come out whenever Kaiyon entered his **Predator State**, which was later found out to be Yonkai's way of forcing his way through so he could protect Kaiyon from danger. However, because he was still inhibited by Kaiyon subconsciously, he wasn't able to fully control himself.

When Kaiyon spent time with Class 4 through their journey, prior to Yonkai's manifestation, whenever Yonkai came out to try and protect Kaiyon, the class collectively called him **Angry Kaiyon**. Whenever Yonkai took over the body, Kaiyon was unable to know of what was happening, and thus suffered a form of memory loss whenever he got the body back into his control. Uniquely to Yonkai, however, despite being subconsciously sealed away, he was able to know what Kaiyon's done.

Like with Kaiyon, Hikaku Taishō separated themselves between their two users, going after the one that best fit their personality. In Yonkai's case, he received Taishō as his Zanpakutō Spirit. It was also during the conversation with Estrellatu did Yonkai learn that he takes after Tsukiwa more, meaning he is Kaiyon's half that is more geared toward **Magic**. While Kaiyon himself isn't too capable in understanding Kido and its effects, Yonkai seems to be able to have a better understanding of its mechanizations. However, between Kaiyon and himself, he is more chaotic, and can be shown to possess extreme anger. But this does not seem to be shown much outside of battles, unless he's been disturbed, because he has calmed down since his split from Kaiyon.

Because he acted like a guardian of sorts to Kaiyon, similarly to an older sibling, within a large portion of Stained, he lacked his own motivation for things, and as such, was in the same place as Kaiyon, for a while, on not knowing what he wanted to do.
