Azazel

"Do you think a world without God is wrong? Do you think a world without God would decay? I am sorry to say but that isn’t the case. Me and you as well are both healthily living like this. —The world moves even without a God."

- Volume 4, Life 4

Azazel is the former Governor General of the Fallen Angels and Grigori. He now serves as a Chemistry Teacher at Kuoh Academy and the advisor of the Occult Research Club.

Appearance
Azazel is a tall man appearing to be in his twenties with an average build, black hair, golden bangs and black goatee. He also possesses twelve jet-black feathered wings that grows out from his back. It is described by Vali to be a never ending black.

After the events in Volume 4, he loses his left arm but replaces it with a prosthetic arm made from his Sacred Gear research.

Personality
It is hard to determine Azazel's personality as he is laid-back yet serious, while also wise and insane at the same time. His character seems to reflect upon the situation at hand. Azazel loves to collect things, (shown when Issei introduced him to video games he collected every console) and a research fanatic, especially on Sacred Gears. He is also shown to be pacifistic, preferring to talk his way out of troubles rather than resorting to violence. He has been shown to care deeply for his fellow Fallen Angels, Shemhazai and Baraqiel.

Azazel has also been shown to be extremely charismatic, being able to endear his Fallen Angel followers. Azazel has complicated feelings on the fact that many of his friends and acquaintances are all married and have a family. It is suggested that Azazel is a pervert because of his fondness for breasts, and also the fact that he has stated to have had hundreds of harems over the millennia. Not to mention that his stated reason for becoming a Fallen Angel all those millennia ago was lust.

History
Originally an Angel from Heaven, during his time there, Azazel had once written a report on his Artificial Sacred Gear, the Blazer Shining Aura Darkness Blade, which was published by Michael during the war much to his embarrassment.

Azazel later lost his place in the Heaven after having sex with a human woman and became a Fallen Angel as punishment from God. Shortly after that, he created the Fallen Angels' organization, Grigori, and became its Governor General. During the Great War between the Three Factions, the Fallen Angels were the first to retreat due to Azazel's order after he had lost many of his subordinates. After retreating from the Great War, Azazel started to research Sacred Gears, creating Artificial Sacred Gears and others objects related to them.

He also made a contract with one of the Five Great Dragon Kings, Fafnir, during his research and created his own Artificial Sacred Gear : the Down Fall Dragon Spear.

At some point before the series begin, Azazel found a young Vali Lucifer abandoned by his parents, took him to Grigori and taught him how to properly use his powers along with his Sacred Gear while raising him.

The Red Dragon Emperor's Awakening
Azazel was briefly mentioned by Raynare in Volume 1 of the novels.

Birth of the Breast Dragon Emperor
Azazel makes his first appearance in Volume 4, introducing himself to Issei. He later attended the meeting between the leaders of the three factions and was the one to propose the peace treaty. He later fought against Katerea Leviathan and was able the defeat the latter at the cost of losing his left arm. He becomes the advisor for the Occult Research Club at the end of Volume 4.

In Volume 5, he accompanies the entire Occult Research Club in their trip back to the Underworld, planning their training menu. He also visits Issei when Issei was training in the mountain with Tannin, handing Issei the lunch box made by the Rias, Akeno, and Asia, asking Issei about his feelings for Akeno and leaving after getting the answer he wants.

In Volume 6, Azazel helped in fending off the Devils of the Old Satan Faction before sensing Ophis who appeared on the spot, challenging Ophis who simply says that Azazel cannot defeat her. The Oppai Dragon Song that he composed was later used to help Issei release his Juggernaut Drive.

The Heroic Oppai Dragon
In Volume 7, Azazel is shown to be busy traveling back and forth between the Underworld and human world. While being assigned as Odin's bodyguard, he asked his friend, Baraqiel, to temporarily take over. After Issei and Akeno met Odin, Rossweisse and Baraqiel while on their date, they all went to the Hyoudou Residence, where Azazel explains the reason to Odin's visit to Japan before going to an Oppai Club with Odin. He later assisted in the initial battle against Loki and Fenrir, with Loki retreating after the Vali Team appeared, despite having the advantage. He later implanted Vritra's remaining Sacred Gears into Genshirou Saji, whom he sent to assist in the battle against Loki.

In Volume 9, Azazel accompanies the second-year students of the Kuoh Academy to Kyoto, finding out that the Kyoto's Youkai leader, Yasaka, was kidnapped by the Khaos Brigade. Azazel and the Gremory Team eventually found the culprits who kidnapped her was the Hero Faction lead by Cao Cao, telling his students to be careful of the True Longinus Cao Cao possesses. He then goes to fight one-on-one against Cao Cao, which ended in a draw as both sides did not go all-out. Azazel later told Issei he called for a "reliable backup" in the form of Sun Wukong and Yu-Long.

In Volume 10, Azazel takes Issei to meet up with some of the Gods watching Rias and Sairaorg's Rating Game, getting along with many of the Gods except for Hades, who he tells Issei to be aware of as Hades is stronger than him. After the Rating Game between Rias and Sairaorg, Azazel went to confront Indra, asking the God if he had known Cao Cao and the whereabouts of the True Longinus which Indra revealed it himself, making Azazel angry. Indra simply says back that what Hades is doing can change the maps of all the factions, making Azazel think on how much he knows. After Indra leaves, Azazel comments on Ophis' ambition that is causing the world to become Chaos. He was later seen visiting Sairaorg, talking with him until Misla's butler came to tell them that Sairaorg's mother had awakened.

In Volume 11, Azazel sets up a meeting between Issei and Ophis. He later accompanies the Occult Research Club members to the Underworld for Issei, Akeno, and Yuuto's Mid-Class promotion test. While those three are resting after the test at the hotel, they were suddenly attacked by Cao Cao and Georg who revealed that they have Samael with them. He then equips his Artificial Sacred Gear but was easily defeated by Cao Cao who used his Medusa's eye on Azazel. After the team was defeated by Cao Cao and Georg, they are attacked by a legion of Grim Reapers sent by Hades with Azazel battling with the Ultimate-Class Grim Reaper, Pluto, one-on-one which ended abruptly by the sudden appearance of Shalba Beelzebub who kidnaps and brainwashes Leonardo, forcefully activating his Balance Breaker, creating 13 gigantic monsters that caused the Dimension Create by Georg to start crumbling. At the end of Volume 11, Azazel, with Vali and Tannin's help, opens the Dragon Gate to summon Issei but was surprised to see only the Evil Pieces returned. Realizing what it meant, he falls down to his knees while scolding Issei for being an idiot.

In Volume 12, after reporting Issei's situation to Sirzechs, he and Sirzechs went to the Underworld with Dulio Gesualdo and Slash Dog as their escorts. While initially thinking that they might have to attack Hades together, after Sirzechs reveals his "true form", Azazel was relieved to find out that Sirzechs' power is ten times more than the original Lucifer, remembering what Lord Gremory told him during their conversation about Sirzechs and Ajuka being Super Devils. After the monsters created by Annihilation Maker were destroyed, ending the crisis of the Underworld, Azazel steps down from his post as Governor General of the Fallen Angels. At the end of Volume 12, Azazel reveals that he was given the post of Supervisor of Issei's town, which is an important alliance location, and became Grigori's Advisor of Special Technology before handing them their certificates for passing the Mid-Class promotion test.

The Legend of Oppai Dragon and his Lively Companions
In Volume 14, Azazel attended the peace conference between the Carmilla Faction of the Vampires and the Three Factions. He decided to go to Romania with Rias and Yuuto and arrange a meeting with the Carmilla Faction.

Azazel wasn't able to secure a meeting with the leader of the Carmilla Faction in Volume 15 due to the ruckus caused by the coup d'etat in the Tepes Faction. He then decided to go to a cafe to ease his boredom and there he met the guys of the Vali team and discussed the reemergence of the Evil Dragons, the Holy Grail, and Euclid Lucifuge.

In Volume 16, Azazel contacted the Occult Research Club members and told them to come to Romania since Rias and Yuuto might have been held captive in the Tepes castle. He then met them in a basement at the outskirts of the Carmilla Faction territory after the Occult Research club members, Bennia, and Loup Garou teleported via a magic circle and made their way to Tepes castle. Rias and Yuuto eventually joined the group and had a meeting with the new "King" of Tepes, Valerie Tepes. After the meeting, Azazel and the group met Rizevim Livan Lucifer and Lilith and was enraged due to the actions of Rizevim. He then participated in the attempt to stop the extraction of the Longinus, Sephiroth Graal, from Valerie and save her; fighting the enhanced Vampires and Grendel along the way. Azazel later helped in defeating the mass-produced Evil Dragons that were rampaging in the Carmilla's castle town. After returning from Romania, he participated in the meeting for the formation of D×D.

When Qlippoth attacked Heaven in Volume 18, Azazel contacted the D×D members and informed them that they have trouble sending reinforcements as the entrance to Heaven was blocked by Qlippoth. After the attack, Azazel talked to Sirzechs regarding the stolen Agreas with the latter revealing that the technology needed to create the Evil Pieces and Brave Saint cards is hidden inside the floating island and there are only 1000 sets of Evil Pieces remaining.

In Volume 19, Azazel talked to Shiva for the God of Destruction to agree to act if ever Trihexa is released from the seals put on him. He then organized the fight against the exorcists that rebelled from the Church. After the fight, Vasco Strada gave a piece of the original Holy Grail to him. Azazel and the Grigori then made a pendant with the piece of the Holy Grail inside it and put it around Valerie's to neck and successfully woke up her consciousness.

In Volume 20, Azazel, along with the Occult Research Club and the Sitri group, went to a dimension owned by Ajuka Beelzebub. After hearing the explanations given by Ajuka revolving the corruption that was prevalent in the Rating Games, Azazel asked Ajuka about the rumors he heard that the Maou has tracked down the locations of the two remaining Longinus, Telos Karma and Innovate Clear. He also asked if the dimension they are currently in is connected to the Longinus. Ajuka replied that the dimension they are in is a product of his. The Maou continued that even for a person like Azazel who is knowledgeable about Sacred Gears will be unable to capture the two mentioned Longinus as they are outside the laws of this world. The group then returned to Kuoh Town after a report came in that Ophis was attacked by Evil Dragons and Issei's parents were taken hostage. The DxD team then prepared to, for the first time, be on the offensive against Qlippoth as Vali's team finally located Agreas' location.

When they arrived in Agreas, Azazel went on his own towards the power chamber of Agreas to try taking control of the floating city. Even though he was able to evade all the traps laid down in the path towards the power chamber, Azazel was not able to enter as guarding the door was Lilith. Azazel was wary of fighting against her as he knows Lilith's power and instead tried to bribe her of letting him in by giving her a candy. Lilith really wanted the candy that Azazel has but she still did not let him through. Seeing that it is a lost cause, Azazel gave up and gave the candy to Lilith. While trying to think of another way to get inside the power chamber, a heavily injured Rizevim appeared from the corridor. Azazel surmised that it must either be Issei or Vali who inflicted that damage to him. After Azazel ridiculed Rizevim of his current state, the two legendary Evil Dragons Apophis and Aži Dahāka appeared through the Dragon Gate. The two of them further ridiculed Rizevim and told them their own plans of attacking the other world. Azazel asked Apophis if it would be possible for them to give back the Holy Grail which Apophis refused as they still need it. After the two Dragons left, Vali appeared in and confronted his grandfather. Rizevim tried to weasel his way out but to no avail. Azazel explained that the reason for his death was him pushing his opponents too far. After Rizevim died, Azazel ventured towards the center of the power chamber. There he saw the sleeping Trihexa. When Azazel tried to stop the whole operation, it was revealed that Rizevim had a back up plan in case of his death in store. Rizevim's soul was used as the final power source to aid in Trihexa's awakening. Azazel then witnessed Trihexa's complete awakening together with Apophis and Azi Dahaka's declaration of war.

Seeing the damage caused by Trihexa and Qlippoth just days after the Imperial Beast's unsealing, Azazel immediately formulate a plan to counter 666. Azazel later appear in the Northern Europe, bidding farewell to Vali, the Vali Team, Tobio and Lavinia as he along with the leaders of the many factions implement Azazel's plan of sealing themselves with 666 inside the Isolation Barrier Field to contain the damage and fight the beast.
