Izuki Kyoko

**Izuki Kyoko** is the Tsuguko of Gyomei Himejima and a minor supporting character in Demon Slayer.

## Appearance

Despite only being 17 years old, Izuki is a hulking figure, standing at around 6'7 and is extremally muscular. He easily towers over his fellow Demon Slayers, and is only shorter then Gyomei Himejima himself. He has long, messy gray and brown which is tied up in a Edo-period ponytail. He has large, kind lavender eyes with small black slits in the center as pupils.

He wears a black version of the classic demon slayer uniform, with silver buttons. He wears a pair of black hakama pants, with a white rope loosely wrapped around his waist instead of the classic belt. He wears a pair of ginger zori, white olive green straps. Atop this he wears a tan haori, which is outlined in white.

## Personality

Despite his massive appearance, Izuki is actually very gentle when it comes to humans. He is very respectful, well spoken and kind. Unlike Gyomei, he is not very sensitive and tends to joke around with his friends. He is somewhat of a trouble maker, constantly playing pranks on the hashira as well as his fellow demon slayers. He has been described as "the one who brightens my day" due to his positive outlook on almost everything.

He loves protecting people, and tends to put everyone else before himself, protecting even elderly folks with his life from demons. He is very good natured and can take jokes and insults very well, and tends to laugh along with the people whom insulted him. He is not as soft as Gyomei and does have a temper, which somehow no one has managed to break.

He is often seen meditating in fields of flowers, as he is very at peace with his inner self. He knows the limits to his abilities and does not underestimate or overestimate himself, which makes him an amazing fighter. Since he has amazing self confidence that makes it hard to break his fighting spirit by insulting or mocking him, as he will just end up laughing with them.

Due to his gentle nature his life goal is to make Giyuu Tomioka smile one time in his life, and he tries everything to make Giyuu smile. He goes as far as redecorating Giyuu's entire room, and to the point where he tricks Shinobu into kissing him.

## Abilities

### Overall Abilities

Despite not even being a hashira yet, most hashira consider Izuki better and stronger them them, seeing him as more worthy of the hashira title then them. He is known as one of the strongest demon slayers currently alive, due to his immense physical strength but also his speed and agility, something that does not come often with people as strong as him. He was trained to his peak physical condition by Gyomei Himejima, meaning that he is almost as strong as Gyomei Himejima himself.

### Physical Abilities

**Immense Speed & Reflexes:** Despite his massive build, in reality Izuki is insanely fast and he possess insane speed and reflexes. He is one of the fastest members in the entire demon slayer corps, his speed shown to rival that of Muichiro Tokito's. During his fight against Doma, he is easily able to dodge and maneuver out of the way of Doma's attacks, which impresses Doma. Doma even says that if he wasn't there, both Inosuke and Doma would be dead by now.

**Immense Stamina & Endurance:** Izuki possesses an insane amount of both stamina and endurance, being able to fight for longer then most of the hashira due to his huge body size. He is able to carry around a massive axe and flail with ease, not even breaking a sweat. As well as that, he can easily push boulders up to twice his size. He was able to hold Doma off for the majority of the fight, allowing both Kanao and Inosuke to get barley injured as well as managing to be the one to kill the weakened Doma.

**Immense Strength:** As well as Gyomei, Izuki is one of the strongest members of the corps, his physical strength being his best feature. He is easily able to lift and swing his massive axe and flail faster then even Kanao can see at Doma. He is able to push boulders double his size with ease and carry both Sanemi and Giyuu on his back without breaking a single sweat.

## Fighting Style

**Kusarigamajutsu:** Like Gyomei, Izuki uses a spiked flail and axe while being in combat, other then the normal Nichirin Katana. As a tsuguko, Izuki is very talented and skilled with this way of fighting, being trained by Gyomei himself. He is able to deflect and attack Doma countless times in the matter of seconds, even impressing Doma.

### Breathing Style

**Stone Breathing** (岩 (いわ) の呼 (こ) 吸 (きゅう) , *Iwa no kokyū*?): A breathing style that Izuki learned from the Stone Hashira, Gyomei. He uses the same forms that was taught to him by Gyomei, which mostly use his amazing sense of hearing and abnormal physical strength to it's advantage. As the Tsuguko of the Stone Hashira, he is the generations second strongest Stone Breathing user, and widely accepted as a hashira, even though he is not one.

* **Second Form: Upper Smash** (弐 (に) ノ型 (かた) 　天 (てん) 面 (めん) 砕 (くだ) き, *Ni no kata: Tenmen Kudaki*?) - The user throws both their axe and spiked flail for a pincer move before smashing down on the chain to cause the flail to then rebound and smash his target from afar.

* **Third Form: Stone Skin** (参 (さん) ノ型 (かた) 　岩 (がん) 軀 (く) の膚 (はだえ) , *San no kata: Ganku no Hadae*?) - The user unleashes a series of slashes with their axe deflecting nearby attacks.

* **Fifth Form: Arcs of Justice** (伍 (ご) ノ型 (かた) 　瓦 (が) 輪 (りん) 刑 (ぎょう) 部 (ぶ) , *Go no kata: Garin Gyōbu*?) - The user utilizes a powerful barrage with their flail and axe, doing a great amount of damage. The axe is destined to hit first with the trajectory of the flail following from the opposite side and slamming into the opponent.

## Equipment

**Nichirin Chained Flail and Axe:** Instead of a Nichirin sword, Izuki wields a weapon similar to a Kusarigama, consisting of an Ono (axe) attached to a Chigiriki (flail) via a long chain. Still, the weapon was forged from the same materials used in the creation of Nichirin swords. Its craftsmanship in particular is noted for being incredibly high-class, being made of pure iron that has absorbed so much sunlight, it was considered even superior to the iron used to forge swords during the Sengoku period, when swordsmithing was at the peak of development.
