Kokuou (Bijuu)

Kokuō (穆王, Kokuō), more commonly known as the Five-Tails (五尾, Gobi), is one of the nine-tailed beasts. Kokuō primarily resembles a massive white horse, but with a dolphin's head. She has two pointed longhorns and two shorter horns in front. She is a rather quiet, polite, and reserved individual but she does have pride in her power as a tailed beast, particularly in her speed. Kokuo's favorite activity is running in dense forests and her caged sealing realm often resembles a forested area. Kokuo has mastery over suiton and katon and specializes in using boil release to enhance taijutsu and bukijutsu.

***Current Jinchuuriki:*** Ito Hoshi

## Guild History:

As with all chakra demons, Kokuo's origins were as a portion of the ten tailed beast (juubi). The juubi was a powerful creature created by Jashin in the earliest period of Evergreen's (SR's) universe for the sole purpose of destroying as much of the dimension as possible. The juubi would travel from galaxy to galaxy consuming as many star systems as possible before Evergreen expended some of her divine power to weaken it by splitting it into nine equal pieces with unique names and identities. The gods Utu and Zelel would weaken the nine demons even further until they were banished and contained to Earth.

In Uzushiogakure, a fallen Kogarashi agent released the five-tailed beast, Kokuou, at the Caldera. It was because of the valiant actions of Karuto Raiken, Sumiko Uzumaki, Saiko, Chie Saegahara, and Chouga Atsui that the demon threat was mitigated and sealed into Koutetsu.

The gobi was later released from Kotetsu.

Nohea Karna got the demon sealed into her after traveling from Arashi on orders by Belamos to train and get stronger. She met a thrill-seeking hunting party and they become good friends. She joined them to hunt their quarry (the five tails). In the end, they all died in battling Kokuo, with their leader Caldwell (the one Nohea was closest to) sealing it into her before she died so Kokuo would not continue its rampage.

Kokuo was later sealed inside a young man known as Coello, who stumbled his way from Leaf Village to the Land of Rivers. The Demon Seal on the young man was weakening by the time he found himself in the rogue mercenary camp owned by TORNA, lead by Ito Hoshi. Ito knocked Coello away from the camp, sensing danger, which was enough to let the gobi loose. Kokuo and Ito engaged in deadly combat as the Bijuu and the mercenary leader. Kokuo blinded Ito by blasting her with a Bijuudama, but Ito managed to make a last ditch effort of sealing the demon inside of herself.

## Traits

Kokuo's resource pools are both 5,000.

Kokuo regenerates chakra equal to the user's body rank per post in combat.

The jinchuuriki is able to draw chakra from Kokuo as an action during combat equal to two ranks above their body rank.

The host can apply [1] tier higher corrosion to their boil release techniques.

If the Kokuo host uses a taijutsu or bukijutsu technique then once per post a massive amount of steam will be released from their body as a free technique that is the same rank as the taijutsu or bukijutsu technique used and applies tiered corrosion status.

Kokuo's Furnace Style grants [2] stat points when stage three is mastered and another [2] stat points in stage six is mastered.

Upon mastery of Demon Cloak Stage 1, Kokuo fully unlocks the water and fire nature transformations in the user as additional elements if the host does not already possess them. Additionally, Kokuo grants the host a free boil release (futton) implant that does not consume an implant slot if the host does not already possess it. If implanted, the host will only be able to use S+ rank boil techniques from Kokuo and not the bloodline itself.

## Demon Attributes

Steam-Powered Warrior | Boil release techniques can be self-korabo'd with taijutsu or bukijutsu techniques. Doing so makes the taijutsu or bukijutsu technique treated as spiritual in collisions and applies the full effects of the boil technique including corrosion.

Heat of Battle | Steam from boil release techniques of B-Rank or above remains in the air, blanketing the whole topic, for [5] of the host's posts and continue applying corrosion as well as burns at tiers appropriate to the original boil technique's rank.

Boiling Point | The massive buildup of combat-enhancing steam pressure in the host's body allows all of their speed and strength stat boosts to be doubled. Additionally, if their speed and strength cannot be enhanced any further then they may use the following strength and speed effects [6] times per battle rather than [4]: If the technique would increase strength then you gain 1 extra tier to physical trauma on contact. If speed would be increased then you are fast enough to perform one extra offensive action in the post you are obtaining the boost in.

## Transformation Stages

### Demon Cloak Stage 1

A cloak of gray chakra with steaming consistency forms around the user can manifest two horse-like tails. Additionally, the host's eyes turn dark blue-green with red markings under them, resembling Kokuo's own eyes.

The user's speed and strength are elevated to 10 for the duration of their transformation while agility and endurance remain unchanged.

Boil release techniques are considered overwhelming during the transformation.

If a taijutsu or bukijutsu technique is used in the same post as a boil release technique then [1] taijutsu or bukijutsu technique can be considered overwhelming.

### Demon Cloak Stage 2

The user is coated in a thick, ominous black and blood red chakra that coats their figure as nothing more than a silhouette of their figure remains. During this stage the user's eyes become frightening white orbs as their head grows horns and their legs and feet become more horse-like, making the host appears like a centaur. The user is often unable to do more than neigh in rage at their foes during this transformation. The user also grows 4 horse-like tails.

The user's agility, endurance, speed, and strength are elevated to 10 while the transformation is active.

Boil release techniques are considered overwhelming during the transformation and cost [1] rank less to cast.

All taijutsu and bukijutsu are considered overwhelming during the transformation.

### Demon Mastery

The host dons a bright white aura of chakra as they and Kokuo are able to unify their will and openly share his chakra and the host's body without reserve. This white steam-like chakra hugs the user's form and clothing tightly, appearing similarly. The user manifests all five horse-like tails, appears as a white centaur with horse legs, and grows all of Kokuo's horns.

The user's strength, agility, and endurance are elevated to 10 while the user's speed is elevated to 12 for the duration of the transformation.

Boil release techniques are considered overwhelming during the transformation and are boosted [1] rank higher during this transformation.

All taijutsu and bukijutsu are considered overwhelming during the transformation and cost [1] rank less to use.

## Furnace Style

Kokuo gives the jinchuuriki access to a unique taijutsu/bukijutsu style called the Furnace Style that combines boil release with martial arts. The host can boil their own chakra to build up powerful steam pressure in the body to greatly enhance their physical strikes and their movement speed.

**Stage One**

**▰ Boil Release: Unrivalled Strength [ Futton: Kairiki Musō ] | Rank X | Complex**

This technique is the basis of Kokuo's Furnace Style. The jinchuuriki forms a handseal and begins boiling their own chakra. The steam pressure builds up in the body over 1 or 2 posts, consuming a supplemental action for each post. The user can then release the steam pressure once their chakra reaches the boiling point in a massive steam blast. This will enhance the user's speed and strength by [2] and increase the rank of the user's boil release and Furnace Style techniques by [1] or [2] depending on the amount of posts spent building steam pressure. These increases only apply to the post that the steam pressure was released in. Additionally, this effect may be continually unkept passed the 2 post duration. Doing so does not further increase ranks, but does hold value for later techniques as described in their descriptions.

**▰ Boil Release: Erupting Propulsion Fist [ Futton: Funsuiken ] | Rank X | Complex**

After increasing their chakra temperature to the boiling point using Boil Release: Unrivalled Strength, the user releases boiling steams from their body and delivers a steam-enhanced punch that can send their opponent flying back 50 feet. The rank cost of this technique will be the same as Unrivalled Strength but will be a rank stronger after being augmented by Unrivalled Strength. This technique applies tiered corrosion and burns depending on its enhanced rank.

**Stage Two**

**▰ Boil Release: Erupting Strong Foot [ Futton: Fungōkyaku ] | Rank X | Complex**

After increasing their chakra temperature to the boiling point using Boil Release: Unrivalled Strength, the user releases boiling steams from their body and delivers a steam-enhanced kick that can send their opponent flying back 50 feet. The rank cost of this technique will be the same as Unrivalled Strength but will be a rank stronger after being augmented by Unrivalled Strength. This technique applies tiered corrosion depending on its enhanced rank. The delivered kick will also ignore armor protections.

**▰ Boil Release: Steam Blast [ Futton: Jōki Burasuto ] | Rank X | Spiritual**

The host forms a handseal and releases a potent blast of hot steam from their mouth. This technique can be increased in rank by the Unrivalled Strength technique but is not required. The ball of steam grows outward into a thirty-foot radius and applies corrosion and burns depending on its rank. While the user exhales the steam a loud whistling sound as if from a kettle is released.

**Stage Three**

**▰ Boil Release: Steam Dash [ Futton: Jōki Bakushin ] | Rank X | Complex**

After increasing their chakra temperature to its boiling point using the Unrivalled Strength technique, the user releases boiling steam from their body, after which, they dash extremely quickly in a straight line, taking the similar approach to a locomotive and creating sounds, which are similar to the ones made by a steam whistle. The user will leave massive amounts of steam in their wake which will inflict tiered burns and corrosion based on this technique's rank which will be increased by the Unrivalled Strength ability. This technique will boost the user's speed by [2] in addition to the [2] point boost from Unrivalled Strength for a total of [4].

**▰ Boil Release: Falling Sword [ Futton: Ochiru Ken ] | Rank X | Complex**

After increasing their chakra temperature to the boiling point using Boil Release: Unrivalled Strength, the user releases boiling steams from their body and delivers a downward steam-enhanced weapon strike that can send their opponent down and break the ground beneath them. The rank cost of this technique will be the same as Unrivalled Strength but will be a rank stronger after being augmented by Unrivalled Strength. This technique applies tiered burns depending on its enhanced rank. The weapon will also apply a higher tier of trauma.

**Stage Four**

**▰ Boil Release: Steam Armor [ Futton: Jōki Yoroi ] | Rank X | Spiritual**

The jinchuuriki coats their body in extremely hot steam that continuously boils outward in a three-foot radius. This steam will apply burns to enemies within its range at a tier that depends on its rank and will defend the user from enemy ninjutsu. If this technique is used during a nature transformation then Kokuo will pay for half of this technique's cost and make it overwhelming.

**▰ Boil Release: Mighty Geyser [ Futton: Tsuyoi Kanketsusen ] | Rank A | Spiritual**

The jinchuuriki forms a handseal before placing a hand to the ground and channel boil chakra through the earth. A massive geyser blast of steam will then erupt out of the ground wherever in the topic the user desires. The geyser of steam can reach up to 50 feet in the air. The technique will apply fourth-tier burns on contact. If this technique is used during a demon transformation then Kokuo will pay half of its cost and make it overwhelming.

**▰ Boil Release: Grevious Burns [ Hisan'na Bānzu ] | Rank A | Passive**

Boil and Furnace style techniques inflicted by the five tails and its jinchuriki have this passive automatically applied them, causing them to require an additional amount of chakra equal to the body rank of the host when healing these wounds. If there is no host then this amount is treated as S+. Additionally, if this is applying to steam that has been built up with Unrivaled Strength, then this amount must be repeatedly paid for each post it was built up for. ( i. e. Steam that was built for two posts with an A-ranked host requires chakra for the healing jutsu as well as paying an A-ranked amount three times ).

**▰ Boil Release: Sauna Bursting [ Futton: Sauna Haretsu ] | Rank A | Complex**

Stamping their feet firmly into place, the demon or host will utilize this technique after Boil Release: Steam Armor has already been used and amplify its effects. Forcefully expelling their steam chakra in all directions at once, the user will emit boiling steam that blows back any techniques weaker than itself and simultaneously melting away those that remain fixed, temperatures in the thread rise so high that tiered burning is applied to those within until an equal strength jutsu is used that is capable of blowing away its lingering presence. The jutsu itself may be upkept each post for its full cost each post in order to continue the blowback effect but is considered stationary for as long as they do so.

**Stage Five**

**▰ Boil Release: Internal Combustion [ Futton: Naibu Nenshō ] | Rank S | Spritual**

Used only once the target is within the boiling steam and has been burned previously with a boil or furnace jutsu, the host or demon revitalizes the steam in the air with their chakra causing it to seek out previously inflicted wounds as entrances in the body. The steam will then enter the body and burn the target from the inside out for three posts. After the third post the target will be left with tiered burns as their insides are devastated.

**▰ Boil Release: Steam Powered Force [ Futton: Jōkidōryoku ] | Rank S | Complex**

Commonly paired with Boil Release: Steam Dash, chakra begins surging through either Kokuō's or the host horns, increasing their strength and durability for ramming. If the host does not have horns they will grow them for this technique. Once readied, the host will ram into their target with their steam-powered force and is capable of knocking them in any direction their wish ( commonly this includes directly behind them where boiling steam has been laid ), if boosted with Unrivaled Strength then this ability is able to keep its full power after defeating techniques its same rank or lower, for a number of times equal to the amount of post spent charging Unrivaled Strength. Additionally, when used with Boil Release: Steam Dash, the power of these two techniques is dealt with simultaneously one after the other. Meaning if you are hit by this jutsu you cannot avoid being hit with Steam Dash nor by extension, the steam directly behind the user if the host or demon chooses to knock the target into the air behind them.

**▰ Boil Release: No Brakes [ Futton: Burēki Nashi ] | Rank S | Passive**

Similar to a locomotive train, Kokuō is slow to start but can't stop once she begins. Each time a target is damaged with a boil or furnace style technique ( including lingering damage from burns ) that was amplified with Unrivaled Strength, the host/demon gains a free charge towards Unrivaled Strength. These charges may be used in place of spending an activation to charge it, as well as having no limit to the amount that can be used all at once.

**Stage Six**

**▰ Boil Release: Boiled Alive [ Futton: Yudeta Ikite iru ] | Rank S+ | Passive**

An advanced passive augment that takes effect only when a target has previously suffered burns due to either a Furnace or Boil style technique. As the user charges up Unrivalled Strength, the burning power of the build-up steam ravages any foe who has not yet been healed from previous damages. This causes the target to suffer additional damage equal to the rank of the attack that is separate from the first, and occurs once for each post it was built up for. ( i. e. Being hit with an S ranked steam attack with a two-post build-up period with Unrivaled Strength does three S ranked instances of damage all at once. Each instance of these attack replications count as a separate technique hitting the target all at once. Does not activate swarming.

**▰ Boil Release: Falling Steam Metoer [ Futton: Rakka Suru Ryūsei ] | Rank S+ | Spritual**

Supercharging themselves with Futton chakra, either the host or demon will use the steam pooling off their body to launch themselves over three hundred feet in the air, only to come crashing back down in a massive cloud of steam chakra surrounding their body in much the same way a meteor could be imagined. Once making contact with the ground a massive eruption is created, causing first a powerful concussive force shockwave that is quickly followed up with a blasting wave of melting Futton chakra. The power of this ability is such that it requires two activations to defend against, once for the bone-breaking shockwave, and a second for the corrosive vapor. This vapor carries with it tiered corrosion and burning as per other boil jutsu.
