Chrono Phantasma
Three years later, in the February of 2200, Azrael was released from his cryogenic cell and had a collar put around him by Sector Seven. He was given a mission by the committee to find the Azure Grimoire and to detain Kokonoe and Tager. The collar prevented him from being able to fight those who did not wish to fight him. He found Kokonoe in her lab and brushed off her brief assault, but was unable to capture her as she teleported away, using the assault to buy time.[4]
Azrael would find Ragna the Bloodedge at some point, forcing him to activate his Azure Grimoire, but this battle was overwritten by the Phenomenon Intervention battle between Izanami and the Amaterasu Unit.[5]
The Battle of Ragna the Bloodedge was set up to lure Azrael into Yabiko's Colosseum where he could be captured by Kokonoe and locked up again. He entered without warning, demolishing the other contestants before fighting Bullet. This fight was much more difficult than the last as Celica's presence made Bullet unable to use Ars Magus, while Azrael's strength was completely unaffected. He broke several of her bones, one injury was even sustained by her just punching him. Aware she would die, Ragna leaped into the arena as Bullet was carried off to the infirmary. Azrael almost managed to make Ragna activate the Azure Grimoire, but the latter's self-control and a vision of his previous fight with Azrael helped him overcome it. The two fought some more until Kagura switched in after Azrael threw a massive attack at Celica (which was blocked by Rachel Alucard casually throwing Gii in the way).
During his battle with Kagura, the Black Knight lost consciousness for just a second which stopped Azrael from continuing his incredible assault. Kagura figured out Azrael's weakness with his collar and created a delay that allowed Kokonoe to teleport him to a dimensional prison, although not before teleporting him to Tager so the latter could throw in an attack for good measure.[6]
