She fused herself with the Cardinal system. Everyone says she's not human anymore because she's shown and stated multiple times in volume 14 to not be human anymore. But the most telling is that when Kirito stabs her she doesn't even bleed blood anymore.

She burns up from Chudelkin's flames before making it out of Underworld, she's dead 100% and not coming back. Her fluctlight is deleted.

Chudelkin was pure incarnation when he final reaches her, he doesn't even have a physical form anymore. He's not even coherent, believing her insults to be confessions of acceptance finally.
