Description
Plutia, also known by the Japanese name Pururut, is the Console Patron Unit, or CPU, of Planeptune in the Ultra Dimension, an alternate world within the Hyperdimension Neptunia series. She represents the Sega Genesis and appears in the game Hyperdimension Neptunia Victory as well as the anime adaptation Hyperdimension Neptunia: The Animation. In her ordinary form she appears as a soft-spoken girl with long purple hair and pink eyes, and she is introduced as a close friend of Noire.

In her civilian form, Plutia is relaxed, gentle, and perpetually drowsy. She speaks slowly, often seems only half awake, and can fall asleep at almost any moment, which makes casual conversation with her difficult and frequently frustrates those around her. She has a kind and caring nature and makes friends easily, but she also shows mild sadistic tendencies even without transforming. She rarely becomes genuinely angry, yet when she is pushed far enough she may automatically transform into her goddess form. She has a fondness for sewing dolls of her friends and relies on coffee to stay functional.

When Plutia undergoes Hard Drive Divinity and assumes her HDD form, she becomes Iris Heart. In this state her personality changes completely: she is cold, playful, and openly sadistic, treating enemies with a mocking, queenly demeanor. Her transformation is so drastic that witnessing it tends to leave even allies shaken, and the other goddesses of the Ultra Dimension are known to fear her in this state.

As the CPU of Planeptune, Plutia is technically responsible for protecting and governing her nation, but she frequently neglects her duties in favor of napping, much to the dismay of Histoire, the being who serves as Planeptune's historian and adviser. Despite her lethargy, she rises to the occasion when the situation demands it. In the anime and in the games, she joins forces with goddesses from both the Ultra Dimension and the Superdimension, assisting in battles against threats such as Azure Heart and the antagonist Rei, and she takes part in the conflict against the Seven Sages. Her close friendship with Noire is one of her defining bonds, and she is also familiar with Nepgear and the other CPU Candidates, though her goddess form frightens them.

Her abilities are tied to her dual nature. In battle she uses her doll creations for attacks, including throwing a doll like a boomerang and causing dolls to rain down on opponents, and she employs a voodoo-doll technique when a sadistic mood strikes her. As Iris Heart, her skills include the attack Verbal Abuse, the strike moves Fighting Viper and Fighting Viper 2, and the ability to inflict fear on enemies when she activates her goddess form. She also supports her party with the healing skills Heal and Hyper Heal, as well as stat-boosting techniques such as Megadaptor and Megamodelta, alongside the powerful damage skill Megidolaon.

Her development across the series centers on the contrast between her sleepy, good-natured civilian self and her merciless goddess form. Although she tends to avoid hard work, she proves to be a dependable ally in crises, and her loyalty to her friends remains consistent regardless of which form she is in.
