Zero Dimension Neptunia Z: Twilight of the Desperate CPU

Nepgear, Uzume Tennouboshi, older Neptune and Umio are looking for Arfoire. Nearby this dungeon, Nepgear and Uzume detect share energy so they decide to check this dungeon.

They do find the share crystal but it was bait set by Arfoire and Crostie. Older Neptune complains to Crostie about leaving her and making her feel lonely. Crostie apologizes and asks her to ditch the group and join them for something more interesting. Older Neptune refuses and Nepgear remembers Crostie as Croire from all the problems she caused in the Ultra Dimension.

Umio asks if that means Croire is not an ally. She confirms and says she is only allied with what makes things interesting for her. In this case, that is Arfoire. Arfoire then transforms to her True Deity of Sin form which Nepgear remembers and she tells the girls, they have little chance of winning.

Regardless the goddesses transform and the girls ready themselves for a fight with Arfoire. They come out on top angering Arfoire. She requests for the power of the CPU from another dimension. Croire gives it to her since it would makes things interesting. Nepgear tells Uzume and older Neptune to stop her but the two fail.

With the power, Dark Purple is revived. Uzume attempts a last ditch effort to stop Arfoire but ends up mortally wounded. The group carries Uzume and flees as Arfoire orders Dark Purple to destroy everything. Croire says that the two of them will be caught but Arfoire does not care. Croire joins the group in fleeing.
