Azrael, also known as the Mad Dog, and the One Who Carries the Death, is a fist-fighting pure bred soldier with super human strength. He debuted as a playable character in BlazBlue: Chronophantasma.
After an anonymous phone call to the 7th Agency by Relius Clover, Azrael is released from his prison by the 7th Agency’s higher-ups to take Ragna the Bloodedge’s Blue Grimoire, although they placed a limiter on him that makes it so he cannot fight those without a fighting will, the sole exceptions being Ragna, Kokonoe and TR-0009 Tager. After being told that he has been frozen for roughly two years, Azrael becomes extremely agitated and attempts an attack on the staff who released him, but fails as he finds out the extent of his limiter; after accepting his fate, he is debriefed on his missions. As well as his mission to take the grimoire, Azrael was commanded to take out Kokonoe and Tager after a suspected treason, something that he accepts with glee. Despite his limiter and the fact he was kept in stasis for so long, Azrael easily shatters a 7th Agency soldier’s arm with what he described as 'a gentle pat', merely minutes after his release.
Immediately following his mission, Azrael begins his hunt for Kokonoe. Soon, he arrives at her recently locked down laboratory and easily breaks in; after a brief battle between the two, Kokonoe launches her Assaulting Broken Bunker towards Azrael and uses the time bought to activate an emergency teleport away from him. Subsequently, Azrael continues his hunt for the scientist and TR-0009.
During his search for the traitors and the Blue, Azrael encounters Bullet and recognizes the emblem on Bullet’s clothing, stating that he remembers it from a long time ago. Bullet immediately asks where he last saw the emblem, but Azrael responds coldly, saying that he cannot give any answers, since he never remembers anyone he has “eaten”. Azrael then reveals that he has heard that Bullet is also searching for Kokonoe, and asks her where she might be. Refusing to give up the information anyway and hoping for answers about her squad, Bullet engages Azrael in combat, something he gladly accepts. After realizing that she could never win this fight and that battling him was practically suicide, Bullet pulls out a smoke grenade and uses the smokescreen as a cover for her to escape from the Mad Dog. Azrael begins his hunt once again, this time a little more entertained after his battle.
Traveling through Downtown in the 6th Hierarchical City of Yabiko, Azrael encounters Tager and Litchi Faye Ling, and asks Tager how nostalgic the place is. Tager, knowing that he does not stand a chance in combat against Azrael, runs with Litchi. However, they are cut short by a surprise appearance of Nu-13, who was sent there to capture Litchi and bring her back to Relius Clover. Knowing that she cannot teleport Tager and Litchi in such short notice, Kokonoe teleports Kagura Mutsuki to their location in a bid to buy time. With Tager setting up teleports for multiple people, Azrael and Nu begin to battle Kagura and Litchi. After a weary battle where both Kagura and Litchi were close to losing, Tager finishes the set up and Kokonoe teleports them out of Downtown. Being alone, and not really knowing each other, Azrael and Nu have a stand off, until Hazama arrives and mocks them, begging to know if either one is going to propose.
Sometime later near the Lakeside Port, Azrael comes across Celica Ayatsuki Mercury and Hakumen; in an attempt to protect Celica, Hakumen engages Azrael in combat, but after a stalemate, Celica sets up a Light Screen and runs away with Hakumen.
Kagura starts a tournament called “Battle of Ragna the Bloodedge” in order to lure Azrael into a trap so that Kokonoe may finally deal with him. The tournament goes according to the plan, until Bullet is to be pitted against Bob. Azrael, having defeated all other entries, including Bob, and making them into what is described as “one lump”, entered the tournament to have as much entertainment as possible as well as to fight Bullet, since she was about to steal his “targets”. Bullet responds to his suggestion, saying that she will fight him and give him the enjoyment he so desperately desires. Bullet further asks if Azrael knows her, trying to get questions out of him once again. This time, however, Azrael responds, saying that not only does he recognize her unit’s emblem, but also that he was once asked to help them in the past; when he turned against them in combat, he found them a challenge and accidentally let one of them slip away from his wrath. Bullet further pushes him to when this was, and Azrael replies saying it was several years before he was captured by Kokonoe and thrown into the “Dog House”. Finally getting all the answers she desired, Bullet rises up against Azrael’s challenge and loses severely, but Azrael refuses to stop. With Tager and Ragna watching as Bullet becomes inches closer to the end of her life, Tager constantly tries to activate a forced teleport to save her but it falls short each time. Ragna, feeling that she will die, jumps into the arena and fights Azrael as the teleport finally works and Bullet is transported to safety.
After the fight, Azrael begins to get extremely furious towards the fact that Ragna refuses to unleash his grimoire. However, after realizing that Celica is in the arena, and recognizing her from their earlier encounter, Azrael begins to launch threats of murdering her in cold blood if Ragna does not activate the Blue. With no response to his threat, Azrael launches an attack at Celica, but Rachel Alucard throws Gii directly in front of the attack, saving Celica from a potentially mortal wound. Ragna finally loses his calm and begins using the grimoire; however, as he does so, he begins to get flashbacks of the potential consequences of Azrael’s full power due to their previous meeting, which was rewound by Event Interference, and decides in the last minute to not use it, since he comes to the realization that he wants power to “not lose things” rather than to “steal”. Azrael unleashes a barrage of anger-filled abuse at Ragna for not unleashing his full power, since he thought Ragna would understand the pain of not being able to use the true power one possesses. Having had enough, Kagura enters the arena and fights with Azrael, but during the fight, Kagura lost consciousness for a second. During said second, Azrael is unable to resume his relentless assault due to his limiter imposed on him by the 7th Agency; Kagura, coming to the conclusion that Azrael cannot fight those who do not want to fight, stopped fighting. Azrael becomes even more annoyed, but before he is able to unleash his anger, Kokonoe suddenly teleports him to Tager for a mere two seconds so that Tager was able to punch him as a stress reliever; immediately after the punch, Kokonoe then again teleports Azrael, but this time, into a dimensional prison, which he can never escape from.
He has escaped from Kokonoe’s dimensional prison by tearing it apart with his bare hands and teamed up with Hades: Izanami, who asked him to defeat the Qualified, promising to open the door to gods that Azrael can fight.
Later, inside the Embryo Azrael, without fight-preventing limiters, fought Kagura, but was defeated with Kagura noticing the flaws in Azrael’s fighting style and with Jin Kisaragi’s help, and Trinity Glassfille teleported him back to the cryogenic prison.
After Ragna recreated their world, Azrael remained in the prison, and Kokonoe ensures he is still there.
