Story[]
A2 battles 9S. Near the battle's end, she cuts off his arm and hacks into his mind with Pod 042's assistance. While navigating his mind, Pod 042 continuously warns A2 that the chances of removing the corruption plaguing 9S are slim at best. A2 suggests she has a plan, but Pod 042 strongly advises against harm against YoRHa units, with A2 expressing admiration for the pod's loyalty. After discovering a slumbering 9S at the end of the labyrinth, A2 tells Pod 042 to take care of him while she tries to accomplish one more thing.
The body of 9S is lifted away from the site by Pod 042 per A2's instruction. His condition following the Tower's destruction is unknown. As Pod 042 leaves with 9S's body, A2 walks towards a pillar of light and hears the laughter of children. She severs the functionality of the structure, causing it to crumble and returning her to reality. A2 mentions that she never realized how beautiful the world was, proclaiming to "everyone" that she is coming. As A2 reaches her hand out to the sky, she perishes within the crumbling Tower's debris.
In the aftermath of the credits, the debris from the destruction of the Tower is seen throughout the area. A lone moose stares at 2B's sword impaled on a rock, hanging on 9S's bag.
