Plutia, called Pururut in Japanese releases, holds the title of Console Patron Unit (CPU) for Planeptune within the Ultra Dimension, a retro-styled parallel world mirroring 1980s aesthetics. Her human form embodies a soft-spoken, lethargic persona, speaking in unhurried tones with an ever-present air of drowsiness. She routinely neglects goddess responsibilities in favor of napping, handcrafting plush dolls, or engaging in playful banter—especially with Neptune. Beneath her calm facade lies a mischievous streak, subtly surfacing through acts like stomping a Neptune-themed voodoo doll during battles. Transforming via Hard Drive Divinity (HDD) into Iris Heart, her demeanor shifts radically. Adopting a dominatrix-esque attire with darkened hair and a commanding presence tinged with menace, she embraces unrestrained sadism. Iris Heart delights in tormenting both allies and foes, deploying biting taunts to unnerve enemies and provoke allies, though her underlying loyalty to protect comrades remains. This duality earns her the nickname "Sadie" from Neptune, referencing her sadistic HDD persona. Plutia’s history centers on interdimensional mediation. In *Hyperdimension Neptunia Victory*, she guides Neptune through Ultra Dimension conflicts against antagonists like Arfoire and the Seven Sages. A critical juncture arises when securing CPU Memories from Pirachu forces her Iris Heart transformation to ensure triumph. Later, she confronts Rei Ryghts, whose dimensional-collapse scheme endangers both Hyper and Ultra Dimensions. During this clash, Plutia teeters on the brinks of corruption from dark energy before Ultra Dimension Rei rescues her. In *Re;Birth3: V Generation*, she joins forces with fellow deities to thwart corporate adversaries Bamo and Regu, rebuffing their bribes and orchestrating tactical countermeasures. Post-victory, she demonstrates pragmatic mercy by advocating exiling the defeated to southern islands. The anime *Hyperdimension Neptunia: The Animation* sees Plutia make an unannounced Hyper Dimension arrival in Episode 6, asserting her Planeptune CPU status. Her laid-back personality and whimsical antics shine through, including collaborating on a slumber party prank to stage a faux demise. Spin-offs like *MegaTagmension Blanc + Neptune VS Zombies* and *Cyberdimension Neptunia: 4 Goddesses Online* place her in eclectic roles—from commanding a zombie battalion to beta-testing games and tailoring costumes—highlighting her adaptability to unconventional scenarios. Relationships blend loyalty with teasing humor. She shares a close camaraderie with Neptune, trading jests and pranks, while her interactions with Noire occasionally spark tension, particularly when Noire’s provocations trigger her Iris Heart shift. Despite her penchant for psychological games, she prioritizes preserving cross-dimensional friendships post-*Victory*. Combat skills include brandishing plush dolls in human form and a Galient Sword in HDD, augmented by electrifying strikes and restorative magic. Statistically, she shines in magical offense but bears modest defenses, offset by buffs and support techniques. Her character design and narrative roots tie to Sega’s legacy, referencing the ill-fated Sega Neptune console and planetary naming traditions, cementing her role in the series’ hardware personification allegory.
