opens above Gamindustri. The four CPUs manage to safely explore the wormhole by navigating an extra-dimensional maze, followed from a distance by a worried Nepgear and Uni. After noticing an incoming monster hoard which Neptune recognizes from Zero Dimension, she stops their advance by destroying the passageway with an explosive. Suddenly, Uzume appears and summons Dark Purple, who then abducts the four CPUs. Nepgear and Uni witness the event and return to Histoire to plan a rescue mission. Histoire reveals that the CPUs were taken to the Zero Dimension but the party should be able to follow by using the Dreamcast since the passageway was destroyed earlier. After sparring with Nepgear, Uni, Ram, Rom, Compa and IF, the four members of Gold Third agree to join the rescue mission.

With older Neptune back in the party, the group explores Heart Dimension and learn that Kurome has the power to induce both nightmares and false happiness, which she is using to corrupt the CPUs like she did previously to Affimojas and Gold Third. She also partially re-wrote the timeline to make the public forget, and thus weaken, the CPUs, but newly acquired Shares are cancelling its effects. The party witness the CPUs' fantasies; with Neptune wanting praise and her nation's happiness, Noire wanting to be a successful voice-actress and socialite, Blanc wanting large breasts and Vert
