Kokushibo

## Introduction

Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that compliments his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic sense that gives more gravitas and authority to his words. He is an adamant rule-follower, punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki, as seen at the Upper Rank gathering.Kokushibo is shown to be humble as well, and he did not hesitate to admit his failure or complain of any difficulty.

He displays a very strong sense of loyalty towards Muzan Kibutsuji, with most of his actions being done with the sole purpose of fulfilling Muzan's goals. Despite exhibiting outward reservation, dignity, and humility, there is a cold and unforgiving side to his personality; his words can be extremely harsh, especially when reprimanding individuals. His threats come off as nothing short of cruel and overwhelmingly serious, and he demands absolute obedience.

### Character Details

As the highest ranking member of the Twelve Kizuki, Kokushibo is an extraordinarily powerful demon, second only to the Demon King, Muzan Kibutsuji himself. He has battled countless Demon Slayers and has amassed vast experience and knowledge over his nearly 500 year long life. His physique is one of the most polished and immense in existence, as not only is he a user of Total Concentration Breathing, but also a marked individual who made use of the Transparent World, as well as the demon that possesses the highest concentration of Muzan's blood in the organization.

**Intelligence**: **Gifted** (As a talented swordsman who has existed for nearly five centuries, Kokushibo has experienced countless battle situations and threats which he has learnt to overcome. This was displayed during his battle with three Hashira and Genya, where he was able to adapt to their special and unique fighting styles and tactics nigh instantaneously after witnessing it. For example, after Muichiro unleashed his first attack against the Upper Rank, he was able to determine he was a user of Mist Breathing, a talented one at that. This was further accentuated through Kokushibo being able to take on Sanemi and Gyomei simultaneously despite both of them being marked and being users of different Breathing Styles, meaning he’d have to deal with 2 vastly different opponents at once, which he did so successfully, even overwhelming them multiple times.)

**Weakness**: Sunlight reduces Demons to ashes. Wisteria flowers are poisonous to all Demons.

**Notable Attacks/Techniques:**

* **First Form: Dark Moon, Evening Palace** ( *Ichi no kata: Yamidzuki - Yoi no Miya*?) - Kokushibo draws his sword and slashes swiftly in a singular horizontal motion in a crescent shape, creating numerous chaotic crescent blades. This technique is extremely reminiscent of Iaijutsu.

* **Second Form: Pearl Flower Moongazing** ( *Ni no kata: Shuka no Rōgetsu*?) - Kokushibo performs several crescent-shaped slashes that defend him from incoming attacks, sending a barrage of crescent blades.

* **Third Form: Loathsome Moon, Chains** ( *San no kata: Enkidzuki - Tsugari*?) - Kokushibo swings his sword rapidly in two gigantic crescent slashes, from which a storm of smaller crescents spread, causing huge destruction in a small area.

* **Fifth Form: Moon Spirit Calamitous Eddy** ( *Go no kata: Geppaku Saika*?) - Kokushibo makes multiple curved slashes layered over one another, creating a rising vortex of sword slashes and crescent moon blades.

* **Sixth Form: Perpetual Night, Lonely Moon - Incessant** (*Roku no kata: Tokoyo Kogetsu - Muken*?) - Kokushibo releases a wild barrage of crescent-shaped slashes several meters in front of him. This technique was powerful enough to overwhelm Sanemi Shinazugawa and so long-ranged that it slices up the surrounding pillars.

* **Seventh Form: Mirror of Misfortune, Moonlit** (*Shichi no kata: Yakkyō - Dzukibae*?) - Kokushibo swings the gigantic version of his sword in a powerful frontal crescent-shaped slash that creates powerful multi-directional long-ranged slashes in the ground.

* **Eighth Form: Moon-Dragon Ringtail** (*Hachi no kata: Getsuryū Rinbi*?) - Kokushibo uses the gigantic version of his sword and creates a singular gigantic crescent-shaped slash that slowly decreases in size, creating dozens of crescent moon blades.

* **Ninth Form: Waning Moonswaths** ( *Ku no kata: Kudaridzuki - Renmen*?) - Kokushibo creates a stream of long-ranged crescent-shaped vertical and horizontal slashes along with numerous crescent moon blades with the gigantic version of his sword.

* **Tenth Form: Drilling Slashes, Moon Through Bamboo Leaves** (*Jū no kata: Senmenzan - Ragetsu*?) - Kokushibo creates a long-ranged triple-layered slash twister full of crescent moon blades with the gigantic version of his sword.

* **Fourteenth Form: Catastrophe, Tenman Crescent Moon** ( *Jū Shi no kata: Kyōhen - Tenman Sengetsu*?) - Kokushibo uses the gigantic version of his sword and creates a chaotic vortex of powerful extremely long-ranged omni-directional slashes that destroys whatever is caught up within its attack radius.

* **Sixteenth Form: Moonbow, Half Moon** ( *Jū Roku no kata: Gekkō - Katawaredzuki*?) - Kokushibo creates a barrage of downward crescent slashes from an extremely long and wide range, resulting in a powerful six-fold slash crashing down on his opponents; the attack itself is powerful enough to create several miniature craters where the slashes have landed.
