Kazuki Hyoudou is another main male protagonist of The Twin Dragons. He is a second-year student at Kuoh Academy along with his elder twin brother, Issei Hyoudou. Kazuki is the captain of the Basketball Club and became their best player.

He was a human who had knowledge of Devils residing in Kuoh Town and had a talent for magic and combat, which is rare for a human born into a normal family, on his back, Kazuki wields the Sacred Gear, Divine Dividing, making him the direct rival of his older twin brother, Issei, and Ddraig; with both promising to fight one another one day in order to find out which one of them were stronger.

Kazuki was reincarnated into an Angel under Gabriel, one of the Four Great Seraph and the Strongest Woman in Heaven as her "Joker". He became the leader of a special team that he formed over the summer known as the Avalon Team.



Kazuki's Profile Picture

Kazuki is a high school student of average height with a far leaner build once compared to his older brother. He has brown unkempt hair and light brown eyes; it was revealed that Sona was the one who altered his hair so that people wouldn't mistake him for his brother anymore. Following his training over the summer with Tiamat, Kazuki had gained a more toned and muscular build compared to before. In his childhood, it is revealed that Kazuki had a much frailer body compared to his older brother.

Kazuki has worn various clothing during the series: his most commonly seen is the male uniform of Kuoh Academy, which is a black blazer worn over a white long-sleeved dress shirt with black vertical lining, a black ribbon on his collar, black pants, and brown dress shoes.

As a member of the Basketball Club, in the middle of practice and during a game or competition, he is seen wearing basketball jersey and shorts with Kuoh Academies logo along with a pair of white sneakers.

After his summer training in Volume 5, Kazuki received a brand new combat suit from Gabriel made in the Fifth Heaven: it is a modified white jacket with black lining, two silver crosses on both sleeves, a black J with angel wings knitted on his breast pocket, a black sleeveless undershirt, modified trousers, and sneakers.

During his training with the Vali Team in Volume 2, his body was transformed into that of a Dragon. Before his dragon power was stabilized by Tiamat, either Akeno or Lucina would have to suck out the dragon power from him. Following Kazuki's training with Tiamat, he learned how to transform a part of him into a Dragon.

Kazuki has shown to have a number of different personality traits. He has shown to be a good-natured and intelligent person. Whether during his time as the star player of the Basketball Team or during his school life, he has shown to hold great confidence in both his intelligence and natural talent. It is due to these traits that Kazuki became known as the "King of Kuoh". He cares a great deal about his whole family as proven as he chose to suppress his Longinus instead of realizing his nature as the White Dragon Emperor as it would mean that others would come after him for either his power or to assassinate him even at the cost of involving his family. Like his brother, many times Kazuki can sometimes "Get into the business of others". This was first shown when he helped Mittlet after her brother attempted to kill both of them, which had soon caused her to look at him as her older brother the same as Koneko. And this is shown when he had helped Akeno overcome her fear of using her power as a Fallen Angel, along with helping her overcome her hatred for her father, Barakiel whom she had formerly blamed for the death of her mother.

Despite his intelligence, like his brother, Kazuki can sometimes be oblivious when it comes to how the other girls romantically feel about him, which he only eventually realizes after they eventually admit it to him. After realizing that he was unable to suppress his Sacred Gear anymore, he soon gained the drive to become stronger than he was so that he could protect those that he cared about. Even though he sometimes seems capable of maintaining his composure, but there are times when he can lose his temper as shown during Rias' Rating Game battle with Raiser Phenex and his Peerage when they were greatly injured and then ridiculed.

Kokabiel's Biggest Mistake Ever

In battle, Kazuki has always been highly tactical, this is due to his desire to find a new solution instead of just running in guns blazing. Unlike his brother who has a habit of charging into situations solely based on his own emotions, Kazuki thinks through the situation that they get in most of the time. He also believes that anything is possible with planning, developing techniques and coming up with strategies. Kazuki constantly shows this during his battles with the Khaos Brigade along with his teammates, the Occult Research Club and the members of the Student Council. Azazel states that his way and Issei's way of fighting are perfect for a King. While Issei continues to fight forward using his "Heart", while Kazuki uses his "Brain" and his ability to adapt to mainly any situation.

It was also revealed that he has a strong fetish for Maids, as shown with his reaction when he first met Grayfia and Lucia after they had transported inside of his bedroom instead of Issei's bedroom where Rias actually was. Kazuki secretly strongly believes that true beauty can be shown when a woman wears a Maid's Outfit, which makes them far cuter and enhance their beauty.

As a child, Kazuki was a timid and shy when it came to interacting with other people that he didn't know. He had also carried great admiration for his older brother, due to his straightforward nature a slightly very timid and shy when it had come to interact with other people, as opposed to his older brother who was always straightforward with how he felt about some people. Kazuki also held a great amount of admiration for his older brother due to that personality trait, and due to him always defending him whenever he was picked on by others. After he was given some great advice by his older brother, be begun to become more confident in himself.

Kazuki as a child

Before both Issei and Kazuki were born their parents had a very hard time conceiving a child failing twice in the process. One day, when their mother finally got pregnant again, their father completely worried about what might happen paced back and forth in front of a Shinto Shrine honestly wishing and praying that this time that they may finally have their own child. When they were finally born, both of them were even more excited they found out that they had two healthy twin boys. They soon named the eldest twin Issei and the youngest twin, Kazuki, and they grew up in a town by the name of Kuoh. Growing up together, their parents recognized Issei as being the straightforward yet kind one, while recognizing Kazuki as being the smart and careful one.

During his childhood, Kazuki has also always been bullied at the park by a number of kids due to his frail body and was always protected by his older brother who he always looked up to. At some point, we both met and befriended Irina Shidou, a very tomboyish girl who lived in the same area as them. Both had soon begun to hang around each other, along with going to the very same Church as both her and her family. This eventually led to both developing a mutual crush for one another before she moved away and leaving him with a silver cross to remember her by. Months afterward, he started trying to be more confident in himself, like his older brother. He then attended the same middle school as Issei, Matsuda, and Motohama.

Flight: Thanks to his Divine Dividing, Kazuki is able to fly using the White Dragon Emperor's Light Wings. Being an Angel, he can fly using his 10 angel wings.



Kazuki using Divide in Balance Breaker: Scale Mail

Divine Dividing (白龍皇の光翼ディバイン・ディバイディング, Dibain Dibaidingu): Kazuki's Sacred Gear and main weapon of choice. The Divine Dividing is listed as one of the first thirteen Longinus, which holds the spirit of the Vanishing Dragon, the White Dragon Emperor, Albion, one of the Heavenly Dragons. It is said to have the power to kill a God once mastered. It takes the form of a pair of light wings with eight energy "feathers" that enables flight that can reach up to light-speed. These wings work in an opposite way in comparison to the Boosted Gear, in which it has the ability to Divide an individual's power by half soon after coming into physical contact with them every 10 seconds, the opponent's drained power is then added to himself and when he reaches his maximum limit, the excess power is then released through his wings. Later on, Kazuki gains the ability to Reflect, allowing him to redirect incoming attacks.
  • Divine Dividing: Scale Mail (白龍皇の鎧ディバイン・ディバイディング・スケイルメイル, Dibain Dibaidingu: Sukeiru Meiru): The Balance Beaker of Divine Dividing that creates a white dragon armor and soon became his primary battle form when up against powerful opponents. Kazuki achieved this form during his battle with Kokabiel after he declared war against both Heaven and the Underworld. In this form, he can use Divide without the normal 10-second limiter. The Divine Dividing also has a second ability, which is capable of halving the size of both objects and living beings through the use of Half Dimension, he doesn't need to make physical contact with the target to use this ability.
  • Juggernaut Drive (覇龍ジャガーノート・ドライヴ, Jagānōto Doraivu): This is a form unique to both the Boosted Gear and Divine Dividing. This temporarily removes the seal placed on Heavenly Dragons granting the user immense power. A drawback of this form causes its user to lose their sanity while having their lifespan devoured by power. However, Kazuki avoids this by instead using his magic reserves as an alternative force, but he can only manage this for only a couple of minutes. In this form, Kazuki fought against Issei after going berserk and activating an incomplete version of his Juggernaut Drive.
  • Royal Wild Card (天使の猶予ロイアル・ワイルド・カード, Roiaru Wairudo Kādo): This is a specialized technique utilized by Kazuki Hyoudou that changes his scale mail armor into different forms based on his own preferences while taking on the characteristics of cards from the brave saints system, while also syncing his dragon slayer abilities with the power of the white dragon emperor.
  • Supreme Silver Card: A far advanced form gained after he mastered the Juggernaut Drive, which makes it far more powerful in comparison. In this form, the color of his scale mail armor is changed into silver and he gains a total of 12 angel wings that shines with a silver light. Like Cardinal Crimson Promotion and Empireo Purgatory Overdrive, it doesn't consume his lifespan. Kazuki has access to a far enhanced variation of Half Dimension that compresses the body of a specific target until the individual ceases to exist called Compression Divider.

Arondight V (エアロンダイ, Earondaito V): Known as the Holy Dragon Knight Sword of Valor, this is the result of Kazuki imbuing his dragon-slayer magic into the remains of Arondight and unlocking the dragon aura belonging to the Hakuryuukou as the result of being sealed in Divine Dividing by Sir Lancelot. It can generate an enormous amount of holy aura and it is strong enough to counter a charged destructive attack from the Demonic Emperor Sword, Gram, the Strongest Demon Sword. It can morph into any kind of sword that matches his desires. Azazel describes it as an imitation of one of the Three Sacred Treasures of Japan, Ame-no-Murakumo-no-Tsurugi, which represents "Valor".


The chant for Divine Dividing's Juggernaut Drive goes as follows:

I, who am about to awaken,
Am the Heavenly Dragon who has taken the Principles of Supremacy from God
I envy the Infinite and I pursue the Dream
I shall become the White Dragon of Supremacy
And I shall take you to the limits of White Paradise!

The chant for Divine Dividing's Supreme Silver Card goes as follows:

I, who am about to awaken
Am the White Dragon Emperor who shall forge his own path towards Heaven
I shall walk down the Road of True Supremacy with the Infinite Drive to surpass the Unbreakable Dream
I will become the Pure Emperor of White Dragon
And I shall show you all Heaven, which glows with a Silver-White Brilliance!
