Uzume Tennouboshi, who is also a CPU. Neptune and Nepgear learn that, like Uzume, they are unable to transform to unlock their true powers in this world due to the absence of Shares (faith from the people) and so the trio journey across the land to locate fragments of power known as Share Crystals which they use to empower themselves enough to reclaim the land from the invading monster hoard. Neptune and Nepgear learn from Umio, Uzume's sentient fish-monster friend, that Uzume has unique abilities that may trigger when the party needs them most. She is also an amnesiac who remembers nothing of her people or the calamity which destroyed her world but believes it to be the work of a giant known as Dark Purple. Uzume's abilities soon begin to benefit the party by granting them Shares from friendly monsters, food, and finally the ability to seal Dark Purple in a pocket dimension; the Sharing Field, where the party are able to defeat her. Nepgear begins repairs on a transportation device to send herself and Neptune home but the facility is attacked by Arfoire; a powerful CPU-like being with a lust for destruction. Neptune was successfully transported home, but Nepgear, out of reflex, jumped out to help save Uzume from Arfoire's forces. This led the two to abandon their post and retreat. Back home, Neptune finds Histoire incapacitated due to her being an artificial life-form who overloaded as a result of her linking the two dimensions to bring Neptune home. With intel from the other CPUs, Neptune sets out to find an ancient artifact belonging to the original CPU of Planeptune which can reboot and upgrade Histoire. Neptune acquires the artifact from a hidden dungeon and begins to restore Histoire, hoping she can bring Nepgear home. Meanwhile, in the Zero Dimension, Nepgear and Uzume attempt to regroup at Uzume's base but are intercepted by Arfoire. Fortunately, the two are able to defeat and capture her with assistance from an alternate, older Neptune. The older Neptune reveals that she is a dimension traveler who comes from a Planeptune under the rule of Plutia (a close friend from the previous game, who rules in another dimension, the Ultra Dimension) who came to the Zero Dimension with the power of Croire (a dimension-crossing antagonist, also from the previous game) after capturing her, though Croire has since escaped. Arfoire manages to escape by
