Yuuto Kiba is one of the male protagonists of High School DxD. He is a second-year student at Kuoh Academy and the school's pretty boy who is adored by many female students and hated by other male students. He is Rias' Knight and a member of the Occult Research Club.


Yuuto new

Yuuto is a handsome young man with short blonde hair, grey eyes and a mole under his left eye.

He wears the Kuoh Academy boys' school uniform, which consists of a black blazer with white accents over a white, long-sleeved dress shirt with a black ribbon on the collar, matching black pants, and brown dress shoes.


Yuuto is an overall upbeat person and cares deeply for his comrades. He's also a very polite individual when it comes to his manner and personality, even considering Issei's initial dislike towards him.

He had a deep hatred towards the Holy Swords up until Volume 3 where the Occult Research Club members and the souls of his friends who were victims of the Holy Sword Project helped him overcome it.

Kiba also considers his rivalry with Issei deeply, going so far as to note that he does one day wish to fight him fair and square. Issei also comments that Kiba is surprisingly a bit lecherous himself.


Kiba's death

Yuuto being found by Rias upon the brink of death

Originally a nameless orphan taken in by the Church and was chosen to be a part of a project called "The Holy Sword Project" supervised by Valper Galilei which led to the deaths of all of his friends and other participants when Valper decided to eliminate them, resulting in the latter's hatred of the Holy Swords namely Excalibur. After successfully escaping the facility with the help of his friends, he finally succumbed to the poison he inhaled. Lying on the ground, he was then found by Rias. After which, he was revived by her and became her servant. During his initial days as Rias' servant, he was distrustful of Rias and all those related to her. He later practices his swordsmanship under Souji Okita, who was the first person he opened up to. One day, when giving tribute to his deceased friends, he was confronted by a stray Devil and fought a hard battle until his master, Okita, comes to rescue him. After this event, he finally opened up to Rias and took up the name Rias thought of specifically for him, "Yuuto Kiba".


The Red Dragon Emperor's AwakeningEdit

Yuuto made his appearance in Volume 1, bringing Issei Hyoudou to the Occult Research Club under Rias' orders. He later assisted Issei in his attempt to save Asia Argento from the Fallen Angel Raynare.

In Volume 2, after the announcement of the Rating Game match between his master and her fiance, Riser Phenex, Yuuto accompanied his allies to a training camp in the mountain for a week. He later participated in the Rating Game where he successfully defeated more than half of Riser's team before being eliminated by Riser's Queen, Yubelluna. He was then seen is Rias' engagement party where he helped Issei fend off the security to open up a path for his friend.

Birth of the Breast Dragon EmperorEdit


Kiba reaches Balance Breaker, Sword of Betrayer

In Volume 3, Yuuto's past came back to haunt him after seeing Issei's photo as a child with Irina Shidou and her father who is holding a Holy Sword. This only got worse after the appearance of Irina and Xenovia Quarta who were ordered to retrieve the stolen Excalibur swords. Issei eventually manages to make a temporary alliance with the Church duo, where they will help the two of them retrieve the Excaliburs in return for allowing Yuuto to destroy the Excalibur and letting go of his past. This allowed Yuuto to learn of the person in charge of the Holy Sword Project, Valper Galilei. The team was eventually attacked by Freed Sellzen and Valper which causes Yuuto to chase after them. Yuuto later returns to help his friends in their fight against the Fallen Angel Leader Kokabiel, Freed, and Valper. He eventually learns the truth behind the Holy Sword Project, and with the help of his friends' spirits, Yuuto was able to achieve his Balance Breaker, the Sword of Betrayer. He then goes on to break the stolen Excalibur with the help of Xenovia. The Occult Research Club was then confronted by Kokabiel, and was overwhelmed by the latter until the intervention of Vali Lucifer who came to retrieve Kokabiel under Azazel's orders.

In Volume 4, during the meeting between the leaders of the Three Factions which was interrupted by the sudden attack from the Khaos Brigade's Old Satan Faction leader, Katerea Leviathan, Yuuto assisted in fighting off the magicians from the Khaos Brigade along with Xenovia. Yuuto also gave a Holy Demonic Sword to the Archangel Michael in exchange for not allowing any Holy Sword research to produce any more victims.

In Volume 5, Yuuto, like the rest of Rias' peerage, returned to the Underworld for the Young Devils Gathering. In the Underworld, Yuuto trained in maintaining and using his Balance Breaker for long fights. During the Rating Game between his master and Sona Sitri, he and Xenovia faced off against Tsubaki Shinra, Tomoe Meguri, and Tsubasa Yura. Yuuto was able to defeat Tomoe and Tsubasa by using the new technique formed by him and Xenovia, "Durandal Birth", which combines the holy aura of Durandal and the holy-demonic swords that sprung forth from the ground. Near the end of the match he chased after Tsubaki but was temporarily interrupted by Akeno before going on to eventually defeat Tsubaki.

Kiba ends "Chimera" Freed once and for all

In Volume 6, during Rias and Diodora Astaroth's Rating Game that was interrupted by the Khaos Brigade, Yuuto fought Freed Sellzen who had become a Chimera, cutting his body to pieces before destroying his head, killing the latter. He later shielded the members of the Gremory group with multiple holy-demonic swords from the impact of the Longinus Smasher. He, along with the rest of the Gremory Team, were last seen cheering for Issei and Asia on their three-legged race.

The Heroic Oppai DragonEdit

In Volume 7, after fending off the Sacred Gear users and anti-monsters sent by the Hero Faction of Khaos Brigade, Yuuto tagged along with Rias, Asia, and Gasper to spy on Issei and Akeno's date but soon lost them when Issei and Akeno escaped. The Occult Research Club were then asked to serve as Odin's bodyguard as they are attacked by the Norse Evil God Loki and Loki's son, Fenrir. The Occult Research Club, along with Baraqiel, Rossweisse and Saji, later teamed up with the Vali Team to fight their final battle against Loki and Fenrir.

In Volume 9, during his trip to Kyoto with the second year students of the Occult Research Club, the team crossed path with Khaos Brigade's Hero Faction who has kidnapped the leader of the YoukaisYasaka. In the battle to rescue Yasaka, Yuuto and Xenovia fought against Siegfried but were easily defeated by him.

Kiba offering to go battle Beruka Furcas

In Volume 10, after being defeated by Siegfried, Yuuto trained to achieved the Balance Breaker of Blade Blacksmith which he reveals in his fight against Beruka Furcas during Rias and Sairaorg Bael's Rating Game. Yuuto, Rossweisse, and Xenovia then faces Sairaorg in a three-on-one battle but lost to the latter (although they managed to cut off one of Sairaorg's arms).

In Volume 11, Yuuto received a promotion recommendation along with Akeno and Issei. While the group was resting after the test, they were ambushed by Cao Cao and Georg who came to steal Ophis' powers. The battle ended with the Gremory and Vali Teams losing to Cao Cao and Ophis' powers being stolen. Both teams were then attacked by a legion of Grim Reapers and Siegfried. He then has his rematch with Siegfried which ended with Yuuto cutting off one of Siegfried's Dragon Arms. Like the other members of the Gremory Team, Yuuto was shocked to learn that Issei had "died" at the end of Volume 11.

Kiba losing his arm during his last fight with Siegfried

At the beginning of Volume 12, Yuuto and the other members of the Gremory Team stayed in the Gremory Palace, while the whole team was still in shock with Issei's death, especially Rias and Akeno. Yuuto later goes to the basement of the Gremory Palace to check on the Vali Team while asking the original Sun Wukong about Samael's curse. The Gremory Team later goes to the Human world to ask the creator of the Evil Pieces, Ajuka Beelzebub, to check on Issei's Evil Pieces and was surprised to see the Old Satan Faction and Siegfried who had came to offer an alliance with Ajuka. He then faces off against Siegfried in their third and final encounter. During the fight, Siegfried used Chaos Break which made his body undergo a demonification process where he transformed into a monstrous spider and fused with his Demon Swords and Sacred Gear. With this new form, Siegfried easily overwhelms all the members of the Gremory Team, cutting off Yuuto's left arm (which he was able to reconnect later in the battle through the combined efforts of Ravel, Koneko and Asia) and injuring both of his legs. The battle was overturned when one of Issei's Evil Pieces transformed into the sword Ascalon, allowing Yuuto to injure Siegfried. Siegfried finally lost to the latter after his strongest Demon Sword, Gram, left him and chose Yuuto as its new wielder. As he received attacks from the Gremory Team with Yuuto dealing the final blow by stabbing him with both Gram and Ascalon, his body started to crumble away. After the battle, Siegfried's remaining Demon Swords chose Yuuto as their new wielder. After Cao Cao's defeat, Arthur challenged Yuuto after deeming him to be a worthy opponent for his Holy King Sword, telling Yuuto that he will fight him when Vali fights Issei, which he quietly accepts. At the end of the same volume, Yuuto is also officially promoted into a Middle-Class Devil.

The Legend of Oppai Dragon and his Lively CompanionsEdit

In Volume 14, Yuuto is shown to be training Xenovia on how to better use her Ex-Durandal, claiming that should Xenovia master all seven abilities of the Excalibur in addition to the Durandal, she would surpass him as a swordsman. He later goes to Romania along with Rias and Azazel in order to find out more about Gasper's unknown power.

In Volume 15, Yuuto accompanies Rias who was staying at the House of Vladi until a Vampire from the House of Tepes asked them to meet the current leader of the Tepes Faction, Valerie Tepes, much to the surprise of the two.

In Volume 16, Yuuto and Rias reunited with their friends who came to the Tepes territory. He later participated in rescuing Valerie from Marius Tepes who attempted to extract the Longinus, Sephiroth Graal, from Valerie where he and his friends fought against the modified Vampires and Grendel. After Rizevim turns all of the modified Vampires into mass-produced Evil Dragons, Yuuto and Rossweisse teamed up together to fend off the mass produced Evil Dragons. After returning to Japan, Yuuto participated in the meeting for the formation of D×D.

Yuuto, along with the other members of the Occult Research Club, went to the Underworld in Volume 17 and participated in the experience day for the school Sona Sitri built located at Auros in the Agares territory. While doing the respective activities assigned to them, Qlippoth managed to surround both Auros and Agreas inside a barrier and announced their intent to attack after a certain period of time. Before the time was up, they reconfirmed their plan and Yuuto ended up pairing with Tsubaki of the Sitri group and fought against the mass-produced Evil Dragons.

Yuuto and the Occult Research Club went to Heaven in Volume 18 to talk to Michael about the Christmas project the alliance is working on. After the meeting, Michael informed them about the death of Church officials and the presence of Evil Dragons were present. Yuuto helped defend Heaven from the attack of Qlippoth. He, along with Rias, Koneko, Gasper, Akeno, Rossweisse, and Cao Cao, fought against the Evil Dragon Ladon and three of Grendel's clones. He was able to successfully defeat a clone with the help of Rossweisse and Akeno. After all the fights were settled, Yuuto and the Occult Research Club celebrated Christmas and it was announced that he will succeed Akeno as the new Vice-President of the club.

Issei and Kiba V19

Issei reminding Yuuto to not die in the upcoming fight

In Volume 19, Yuuto participated in the fight against the exorcists that rebelled against the Church. He requested to transfer to the group that would fight against Ewald Cristaldi saying that he doesn't want to fight against him for revenge but as a challenge against the former wielder of Excalibur. Before the fight, Issei reminded him not to take his life for granted and that he should return alive. Struggled in the fight against Ewald after being dosed with enhanced Holy Water, Yuuto almost wielded Gram risking his life-span being devoured by the Demonic Sword but was stopped by Dulio Gesualdo, saying to save that against Qlippoth and hugged Yuuto, seeing him as his brother since he also came from one of the Church facilities. Dulio used his technique, Speranza Bolla di Sapone, that made Yuuto remember the things important to him. Because of this, Yuuto was able to use a new technique, siphoning the holy aura of the opposing holy sword, and was able to defeat Ewald with the combined efforts of Irina, Dulio and Griselda Quarta. After the fight against Ewald, him and Irina transferred over to the field where the Gremory team, Saji, and Arthur was fighting against the group led by Vasco Strada. Yuuto attacked Vasco but the latter was able to easily block Yuuto's sword and crush it his bare hands. After the fight against Strada, Walburga appeared and fought against them and was defeated with their combined efforts. Before Vasco was taken away for interrogation, he introduced a girl from Yuuto's past, Tosca. Yuuto was overjoyed with their reunion and hugged each other while crying. Vasco told Yuuto that she survived the Holy Sword Project because of her Sacred Gear and he wants for Yuuto to take care of her.

Kiba sword birth

Kiba creating numerous Demon Swords using "Sword Birth"

Sword Birth (魔剣創造ソード・バース, Sōdo Bāsu): Yuuto's primary weapon and Sacred Gear, which has the ability to create an infinite number of Demon Swords with multiple properties at his disposal, such as the Holy Eraser and Flame Delete.

  • Sword of Betrayer (双覇の聖魔剣ソード・オブ・ビトレイヤー, Sōdo obu Bitoreiyā): Yuuto's irregular Balance Breaker. It is a fusion of a Demonic and a Holy Sword. He achived it during the fight with Freed after he "merged" his Sacred Gear with the spirit of his deceased comrades. Yuuto is also able to create Holy Demonic Swords with different elemental attributes such as lighting and ice. In Volume 19, Yuuto's Holy Demonic Sword gains a new ability to use it's Demonic power to absorb any Holy attribute to enhance it's own, the same can be done in vice versa.

Blade Blacksmith (聖剣創造ブレード・ブラックスミス, Burēdo Burakkusumisu): Yuuto receives it from the spirit of one of his lost comrades. It has the ability to create numerous Holy Swords of different attributes. He gained it in the events of Volume 3 (partially hinted in Volume 9 but was not revealed until Volume 10).

  • Glory Drag Trooper (聖覇の竜騎士団グローリィ・ドラグ・トルーパー, Gurōryi Doragu Torūpā): Yuuto's sub-species Balance Breaker. It creates an army of Dragon Knights that can copy the techniques and speed of the user, though at this moment it can only copy Yuuto's speed. He can also equip armor like the ones worn by his Dragon Knights. He, however, cannot use both Balance Breakers at the same time so he can only choose to use either the Sword of Betrayer or Glory Drag Trooper.

Demon Swords (魔剣, Maken): During and after the battle with Siegfried in Volume 12, Yuuto gained possession of the Demon Swords previously owned by Siegfried.

  • Gram (グラム, Guramu): Also known as the Sword of the Sun, is the strongest Demon Sword. Called as the Demonic Emperor Sword (魔帝剣 Mateiken), it is a Dragon Slayer sword with the destructive power of the Holy Sword Durandal, which causes Yuuto to compare it to a combination of Ascalon and Durandal, but does not need to be charged to do destructive attacks, which he thought meant it was "more" powerful than Durandal and is sharper than the Holy Demonic Sword he creates. Yuuto still cannot control it correctly as Gram drains his energy at a very fast rate and makes Yuuto's condition worse the more he uses it.
  • Balmung (バルムンク, Barumunku): A Demon Sword from Norse mythology with a drill-like aura. It is capable of creating powerful whirlwinds.
  • Nothung (ノートゥング, Nōtungu): A Demon Sword that can rip through space-time.
  • Tyrfing (ディルヴィング, Diruvingu): A Demon Sword that can create craters.
  • Dáinsleif (ダインスレイヴ, Dainsureivu): A Demon Sword that creates huge pillars of ice from the ground.
