Pish, referred to as Peashy in localized media, is a youthful resident of the Ultra Dimension’s Planeptune. Originally sheltered by Planeptune’s Basilicom, she becomes a victim of the Seven Sages, who forcibly convert her into a Console Patron Unit named Yellow Heart. This artificial ascension amplifies her physical power without refining her cognitive maturity, resulting in unpredictable, childlike impulsivity.
In her base form, she sports strawberry blonde hair fastened by red bobbles, cerulean-blue eyes, and a playful bee-patterned jumpsuit paired with cat-paw gloves. Her Yellow Heart transformation reshapes her into a voluptuous figure with flowing golden hair, clad in a sleek white bodysuit trimmed with black, red, and yellow motifs. Despite her mature physique, her demeanor stays mischievously energetic, prone to chaotic playfulness and tearful reactions. As Yellow Heart, she adopts a slightly more focused attitude but retains her airheaded charm.
During *Hyperdimension Neptunia Victory*, the Seven Sages exploit her naive loyalty to Anonydeath and Rei—whom she falsely idolizes as parental figures—to orchestrate assaults on rival CPUs. Post-defeat, severed from an external power amplifier, she reverts to her child form but remains under brainwashing. Neptune and Plutia later restore her memories through sentimental keepsakes, prompting her to defect from the Sages and ally with Planeptune. She subsequently aids in halting Rei Ryghts’ multiverse annihilation scheme, attracting persistent rivalry between Hyper and Ultra Dimension Vert for her guardianship.
In *Hyperdimension Neptunia Re;Birth3*, she combats monsters and corrupted beings during a crisis involving rogue developers producing predatory mobile games. Spin-offs like *MegaTagmension Blanc + Neptune VS Zombies* cast her as a freshman entangled in a zombie outbreak, while *Cyberdimension Neptunia: 4 Goddesses Online* features her as a beta tester and merchant. A non-canon anime episode humorously depicts her faking her death to prank Neptune.
Her powers include Hard Drive Divinity (HDD) transformation into Yellow Heart, augmented combat proficiency, elemental strikes, and claw-based weaponry. Share energy bolsters her endurance, enabling regeneration and resistance to ailments. Key relationships include Plutia, instrumental in restoring her memories, and Neptune, whom she trusts as a guardian despite their ambiguous familial dynamic.
