And he became the leader of the special team, which is formed by him 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.

He has worn various clothing throughout the series, his most common is his usual Kuoh Academy boys' school uniform, 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, he is seen wearing basketball jersey and shorts with Kuoh Academies' colors along with a pair of white sneakers.

Near the end of the summer, Gabriel had a new pair of combat clothing made for him in the Heaven Research Department. It consists of a white modified jacket with black lining on them, two silver cross designed on both of his sleeves, a with a black J (in Old English) along with a single angel wing knitted on his breast pocket, a black sleeveless undershirt, with modified white trousers and sneakers.

During the battle against the Gremory and Riser Phenex, his entire body was transformed into that of a white dragon. Similar to Issei, in order for him to appear human, Akeno had performed a ritual that would suck out the power of the dragon out of his new body allowing him to appear human. In his dragon form, his eyes turn blue and his hair turns spiky white.

Personality Edit

Kazuki carries a number of different personality traits shown throughout the entire series. At first, he has shown to have a great deal of confidence in his abilities, such as his intelligence and natural talent. Eventually, Kazuki joined the Basketball Team and eventually became their star player. This soon led to him becoming very popular with the females in Kuoh Academy, along with this eventually giving him the title "King of Kuoh". He also possesses a great deal of confidence in himself, but Kazuki care even more about his family since they were the reason why he chose to suppress his Longinus instead of just awakening it in order keep over beings from sensing it as this was one of the reasons why he decided to suppress his Sacred Gear instead of awakening it, to keep over beings from sensing it.

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 formally a very timid and shy when it had come to interact 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 and he 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 of them 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.

Powers & AbilitiesEdit

Great Magic Power: In the beginning of his second-year in Kuoh, it was revealed that Kazuki held great levels of latent magical potential which was high enough for him to suppress his Longinus. Training with both Kuroka and Le Fay, who're both skilled in areas of magic, Kazuki's magical abilities grew to the point where he could fight on the same level as Raiser's Queen, Yubelluna.

  • White Dragon Slayer Magic: A form of magic that grants him the ability to slay dragons and dragon-related beings. Before it was modified by him to match his fighting style and so that it wouldn't negatively affect him, it granted him the ability to produce and control white flames from any part of his body; allowing him to use it them in both close and long-range combat, while granting Kazuki a resistance to said element and with the ability to absorb flames to restore his lost magical power. After he realized that this magic had an adverse effect on his sacred gear, Kazuki worked on altering its formula; this soon led to him changed its "Fire-Element" to "Light".

After making it in Kuoh Academy as a first-year, even being complimented by Sona as being a skilled technician and as a talented strategist.

It is said to have the power to kill a God when fully mastered. Divine Dividing takes the form of a pair of light wings on his back, which grants Kazuki the ability of flight that can reach light-speed. These light 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 without limit and add to their own, upon reaching his limit the excess power is released through his light wings.

This temporarily removes the seal placed on the Heavenly Dragons granting the user immense power, which is on par with the God and Maou. The Juggernaut Drive, however, causes the user to lose their sanity while having their lifespan devoured by the power. He avoids this by instead uses his magical reserves as an alternative source in the place of his lifespan, but he can barely manage to use it for 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): The Royal Wild Card is a specialized technique utilized by Kazuki Hyoudou that changes his Scale Mail armor into a different form based on his preference and it also synchronizes his Dragon-Slayer abilities and his power as the White Dragon Emperor.
    • Vanishing White Ace: Wild Card's Ace form. In this form, Kazuki possesses a balance in his offense, speed, and mobility that far outranks his scale mail armor. His armor in this form is instead a white exoskeleton that protects his limbs while matching his physical stature.
      • White Arondight: Vanishing White Ace's main weapon. This is formed from what remained of the Holy Knight Sword, Arondight after it was broken by both Siegfried and Heracles.

    • Vanishing Vanguard Queen: Wild Card's Queen Form. In this form, Kazuki possesses an enormous balance in terms of magical offense and defense.

      • Divine Retribution: Its respected finishing move that unleashes a powerful torrent of light imbued with dragon-slayer powers rivaling his brother's Dragon Blaster.
    • Vanshing Knighted Jack: Wild Card's Jack Form. In this form, Kazuki possesses an enormous balance in terms of power and speed. His armor in this form resembles his ace form, but a bit thicker yet leaner and having more reptilian features.
      • Divine Drive: Its respected finishing move that releases an immensely fast barrage of light-speed attacks.
