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. He challenged Ophis, who simply said that Azazel could not 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 for 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 Realm of the Dead 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 members 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 on 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 are hidden inside the floating island and there are only 1000 sets of Evil Pieces remaining.
In the Extra Life of DX.1, in the club room, Azazel hears everyone's interests in a rematch against Riser Phenex which he then begins to set up. Days after the match, when some wonder if they would win against Seekvaira Agares in a Scramble Flag match, it immediately started getting set up.
In Volume 19, Azazel talked to Shiva for the God of Destruction to agree to act if Trihexa is ever 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 neck and successfully awakened 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 D×D 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 trying to bribe Lilith with a chocolate bar
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 on 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 backup 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.

Azazel with Sirzechs and Elmenhilde
In Volume 21, Seeing the damage caused by Trihexa and Qlippoth just days after the Imperial Beast's unsealing, Azazel immediately formulated a plan to counter 666. Azazel later appeared 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[1].
Red Dragon Emperor of the Blazing Truth × White Dragon Emperor of the Morning Star: The True Dragon(s) of the Kuoh Academy[]
Sometime after Issei's match with Baraqiel in Volume 22, he was summoned by Ajuka to his personal research facility in the Satan’s territory, there he showed him a large screen displaying a live broadcast of Azazel and the others in the Barrier Field who were battling Trihexa. They revealed that communication is possible also that supplies are regularly sent over for them and that it's currently confidential with only a few people are aware of it. His talk was briefly interrupted by Serafall who was hoping to see Sona, Sirzechs was the third to appear on the monitor and took the former Fallen Angels place to talk with Issei. Sirzechs revealed the reason for this meeting was that he, Azazel and Ajuka are establishing a secret intelligence bureau called EXE and they wanted Issei to be its intelligence officer with the establishment being planned for 2 to 3 years from now after dealing with the post-war rehabilitation and the management of the international tournament. While Issei is not confident enough on taking such a role, Sirzechs told him that for now he will need to learn together with his team over time, he responds by saying he will think about it.
In Volume 23, Issei paid a visit to Ajuka's research facility to speak with them again where explained the events that has happened since then. Azazel appeared on the display while complaining to Sirzechs and Serafall how rowdy they were. He noticed that Issei felt troubled, he explained it was to do with both the tournament and being a King, Azazel then asked the boy if he had ever truly enjoyed a fight after becoming a Devil. Issei answer no as most of his fights were purposely to survive and granting Rias certain victory when he worked under her, Azazel lighten him up by reminding him that the tournament isn't a serious fight but purely a game and encouraged to enjoy his youth while he still can. Michael then appeared teasing Azazel on how childish he acted when he created the Blazer Shining or Darkness Blade which angered the former Fallen Angel.
In Volume 24, Azazel and Sirzechs spoke with Ajuka over their agenda to want Issei and Vali to succeed two of the seat of the new 7 Great Satans System, but they heard politicians associated with the first-generation Bael raised objections against to this. Ajuka confirmed the minimal conditions they needed were to be among the top 4 in the tournament. They then worried over Hades taking action from behind the scenes, but Azazel showed confidence that the Two Heavenly Dragons will handle it.
Azazel coined that the Asmodeus title would suit Issei as it represented lust and viewed the new system similar to the 7 Deadly Sins, though Falbium showed no objection, he refuted Azazel that he himself was not lustful. Sirzechs though of having an 8th special seat for Issei, Azazel laughed at the idea as it went against the meaning of the 7 sins, Azazel then though that the 8th sin would be "Oppai Dragon" and that it would make Ddraig cry. When Sirzechs expressed his want to see his future nephews and nieces, Azazel jokingly remarked that there will be a lot of children with different mothers, even bring the assumption that Sona may have kids with someone by then. Serafall objected to his statement as she believed that anyone who dares to marry her younger sister must pass her groom candidates training; as in must be stronger than her and defeat Sirzechs, although Azazel commented with a bitter smile that the Sitri Clans future may be bleak for in order to find such a groom would be impossible.
Azazel reappeared in True Volume 3, speaking with Ajuka and becoming impressed with Team DxD’s achievement of defeat Erebus and Tartarus. He expects that the battle against Hades is near and learned that they’ll talked about Issei being promoted to Ultimate-class devils for defeating Vidar, Nyx, Erebus, and Tartarus, as well the other members of Team DxD also receiving their promotions.
In True Volume 4, Azazel was shown by Ajuka the footage of the girls trying to help Issei regain his perversion, making him realize that Hades picked up on his UFO incident that made lose his perversion by using the user of the Longinus Alphecca Tyrant. After Team DxD defeated Hades and Angra Mainyu, Azazel learned about the gods abduction at the hands of the Evies and asked Ajuka about the materials that was provided to them by the future Gasper, which he revealed that the analysis is still ongoing, angering Azazel that the Evies arrived earlier. Disappointed to the fact that Azazel and the others in the Insolation Barrier Field cannot leave the place, but Ajuka revealed that he intends to follow the plan to reveal the Underworld Lifeforms to the other factions. As Odin and Zeus enter their conversation, Azazel revealed to them that the Evies have arrived, surprising the former chief-gods and leading to believe that Melvazoa and his subordinates have arrived earlier until Azazel corrects them that the one arriving is Regalzava.
