This makes him the was the rival of his elder brother Issei and Ddraig, both brothers promised to fight each other one day to find out which one of them were stronger.

Appearance Edit


Kazuki's Profile Picture

Kazuki is a 17yr old high school student of average height along with a far more leaner build compared to his older brother, brown slightly unkempt hair and light brown eyes. Following his training over the summer with Tiamat, Kazuki had gained a more toned and muscular build compared to before.

He has worn various outfits throughout the entire series, his most common outfit is the usual Kuoh Academy boys' school uniform, which is a black blazer with white accents, a white long-sleeved button-down 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, during both games and practice, Kazuki would wear a basketball jersey and shorts that carry Kuoh Academy's colors along with sneakers.

Near then end of the Summer Break, within the Fifth Heaven's Research Department, Gabriel had a change of clothing made for him. They consists of a white modified short-sleeved jacket that is modified to handle great amounts of damage, with silver crosses designed on both of his sleeves that also has black lining on his clothing, along with a black J (in Old English) with a single angel wing knitted onto his jacket's 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 has shown to carry different personality traits as shown in the series. At first, Kazuki has shown to carry a great amount of confidence in his capabilities, such as his intelligence and his natural talent. Eventually, he joined the Basketball Team and he soon 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". Even though he has great confidence in himself, Kazuki has also shown to care even more about his family, 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 seem 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 very tactical, this is due to his strategic personality. Unlike his brother, Issei, who originally makes it a habit of charging into situations mainly based on his emotions, he mostly thinks through the situation that they get in most of the time. He also strongly 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 and along with his teammates, the Occult Research Club and the Student Council members. 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 carries a strong fetish she 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 more cute and beautiful.

As a child, Kazuki was formally a very timid and shy when it had come to interactive 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 interacting with other people, as opposed to his older brother who was always straightforward with how he felt about some people. He had held a great amount of admiration for his older brother due to that very 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, Kazuki had begun to become more confident in himself.

History Edit

Shu in Lost Christmas

Kazuki as a child

Initially, both their parents had a great deal of trouble in conceiving a child, failing twice in the process. So when their mother finally got pregnant for the first time, their father who was incredibly worried had paced back and forth in front of the Shinto Shrine honestly wishing that this time they would succeed in having their own child.

When they were finally born, both of them were even more excited that 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 had recognized Issei as being the straightforward yet kind one, while recognizing Kazuki as being the smart and careful one.

Kazuki had also used to be bullied at the park and he was always protected by his older brother, Issei, who he always looked up to. At some point, he both met and befriended Irina Shidou, a 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 lead to both of them developing a mutual crush towards each other. Before she moved away she gave Kazuki a silver cross that had belonged to her. But Kazuki left was left sad by her leaving Kuoh. Kazuki then 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 & Abilities Edit

Great Magic Power: During his second-year of Kuoh Academy, it was revealed that Kazuki held high-levels of latent magic potential, which was high enough for him to suppress his own Longinus Sacred Gear. His control was high enough for him to create a softball size of of pure magic power. Training with Kuoh and Ley Fay, both who are skilled in areas of magic, his magical power grew to the point where Kazuki could fight on par with Raiser Phenex's Queen, Yubelluna, who fought on par with Akeno (During their Rating Game match). Several times, he has been praised by Azazel for both his high levels of magic power and talent, which are rare among humans with no relation to Magicians. Soon his magical power grew to be on par with even an Upper High-Class Devil. 

  • Dragon Shot: Kazuki is capable of using his brother’s most well-known signature move and used, in where he fires off a bluish-white beam of energy by concentrating his magical power. This move can also be used in tandem with his Divine Dividing, after he halves and absorbs his opponent’s own power and increases its destructive power.

Great Strength: At the start, Kazuki had a very limited amount of strength for a human, as shown when he was able to send Gadreel, a four-winged fallen angel flying with a single kick (though he was blindsided). Training with both Vali and Bikou along with gaining his Humanoid Dragon body, his physical strength increased to the point where he could fight against a Mid-Class Devil and Fallen Angels. Once he trained with Tiamat, the strongest of the Dragon Kings, he could fight on par with High-Class Devils. 

Immense Speed: Kazuki is noticeably faster than an average human, capable of outpacing a four-winged Fallen Angel. After his training with Arthur, his speed had increased to the point where he could match Kiba. His speed had developed over the summer with his training along with Tiamat, his speed had increased to the point where it was difficult for him to tell where he went.

High Durability: Because of his former human body, he could barely take on very much damage shown during his training with Vali (albeit he was holding back). Gaining his new humanoid dragon body, Kazuki's endurance had increased greatly. Due to his training with over the summer with the strongest dragon king, Tiamat, he could handle the excess power that he had taken using his Divine Dividing.

Known as the second smartest student in Kuoh Academy next to Sona, his skills have been shown several times during combat even studying his opponent's abilities and figure out a way to counter them. As described by Azazel, Kazuki desires to be more versatile so that he could react to most situations and then alter his strategy, a perfect example of a technique-type.

Master Combatant: Kazuki originally held very minimal capabilities in combat, barely being capable of fighting up against a Fallen Angel or Devil. But after training with Bikou who is skilled in Martial Arts, he managed to pick up the basics in using Martial Arts and was capable of fighting against High-Class Devils and other beings up the same rank. Following his training with Tiamat over the summer, he began to learn Chinese Martial Arts, which compliments his own style of fighting. As shown during his matches against his older brother who is purely a Power-Type Fighter, he was capable of deflecting his powerful attacks using fluid movements.

Master Swordsman: During the battle against the Stray Exorcists who attempted to stop him, Rias and Akeno from stopping them from going into the abandoned Church, he had shown capable of wielding one of their light swords against the far more experienced priests.

After the short training with the skilled veteran swordsman from Kyoto over the summer, he has become capable of fighting on par with other Master Swordsmen like; Kiba, Xenovia, Arthur, and Siegfried.

Flight: Thanks to his Divine Dividing, Kazuki is able to fly using the White Dragon Emperor's Light Wings. And after being reincarnated into an Angel he can fly using his 8 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): also known as the White Dragon Emperor's Light Wings. Kazuki's Sacred Gear and main weapon. Divine Dividing is one of the 14 Longinus which holds the spirit of the Vanishing Dragon, the White Dragon Emperor, Albion, one of the Heavenly Dragons. It is said to be one of the weapons that carry the power to kill a God when fully mastered. Divine Dividing takes the form of a pair of light wings on his back, which enables flight that can reach light-speed. These wings work in the opposite way of Issei's Boosted Gear, in which it has the ability to Divide the opponent's power by half after coming into physical contact with them every 10 seconds without limit and adding to their own, upon reaching his limit the excess power is released through his light wings. Later it gains the ability of Reflect, the ability 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): also known as the White Dragon Emperor Armor.

Kazuki first achieved Balance Breaker during his battle with Kokabiel declaring war against the Devil of Kuoh Academy. From this point, Kazuki can Divide without the 10-second limit. Divine Dividing 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): Also known as Dragon of Supremacy, a form unique to both the Boosted Gear and Divine Dividing. This Juggernaut Drive 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 also having their lifespan devoured by the power. However, he avoids this by using his magical power as an alternative source in place of his lifespan, but unlike Vali, he can barely use it for five minutes. In this form, Kazuki was able to fight against Issei after going berserk and activating an incomplete version of his Juggernaut Drive.

Arondight (エアロンダイ, Earondaito): Kazuki's second weapon, also known as the Light of the Lake. This is considered to be the holy sword that was lost a long time before the start of the series and is considered to be the counterpart of the holy sword, Caliburn. It is capable of releasing a very powerful holy wave capable of releasing a powerful holy aura on par with Excalibur and Durandal, along with possessing a blade capable of tearing through anything. And this possesses the ability to manipulate its holy aura while being capable of giving it a dense solid shape.
