"Hades that descended to bring "death" equally to all living things. She possessed the body of Ragna and Jin's younger sister "Saya" and provided the template for the Boundary Interface Prime Field Device series above No.10. She was the long-time "Imperator" of the NOL and aimed to bring about "Doomsday." And now, she has achieved that goal&mdash;"

Before the Doomsday began, Izanami went to the Amaterasu Unit, and opened it up, showing that inside, there was no one. She soon summoned Noel and Rachel to her location to force Noel to Observe where she had placed Ragna – inside the Embryo. She then journeyed into the Embryo herself.

Inside, she bathed in one of the Prime Field coffins, asking Relius about the vessel she was possessing. She dressed herself and travelled to Ikaruga, realising that Nine had set the chosen against her, and later watched as Relius and Ragna fought in Akitsu, being interrupted by Azrael and fighting him. He grew bored however since there is no life emanating from her, and the two formed a pact – should Azrael defeat all the chosen, Izanami would grant him access to the world of the Gods where he could fight them for all eternity.

Witnessing Azrael fighting against Ragna, she summoned the latter to her location next to the Amaterasu Unit. They fought, every moment with her mocking him with Saya’s voice. Noticing that his strikes were filled with unwillingness to hurt his sister’s body, Izanami rammed herself into his sword, telling him that she cannot die as Amaterasu’s Drive. Amaterasu intervened and used phenomenon intervention to send Ragna away from her location.

Izanami infiltrated Nine’s workshop, finding her defeated by Ragna. She offered death to Kokonoe, Celica, Jubei, Ragna, Jin, Nine, and Rachel before being stopped by one of Nine’s strongest fields. Nu followed after her master, attacking the witch but being stopped by Jubei. Izanami remained inside the workshop as time froze over, watching Nine die. She broke the space-time, transferring the Requiem to a different location and issuing an illusionary message to Ragna, Noel, Kagura, Jin, Hakumen, Tsubaki, and Ex Machina: Minerva, warning them all that if they could not find her in three hours, they would all perish in Requiem’s explosion. Eventually, Ragna and Mu found her, and she was absorbed by the latter despite being up a resilient fight. Izanami, from that point on, no longer existed, having merged together with Noel’s soul.
