Noire is the Console Patron Unit of Lastation, embodying Sony PlayStation home consoles. Her standard appearance features long black twintails with blue ribbons, red eyes, and a sophisticated dark blue, white, red, and gold-accented dress. Transforming into her deity state, Black Heart, alters her hair to flowing white and her eyes to teal or blue-green, accompanied by a black combat suit featuring a cleavage window. Later appearances, such as in *Victory*, show her human form in a black tanktop and pleated skirt, while her Next Generation form adds blue accents, an analytical eyepiece headset, and elongated pigtails with mechanical elements. Personality-wise, she embodies the tsundere archetype: outwardly diligent and self-reliant, yet internally insecure about her social image. She habitually overworks, refusing help until exhaustion or illness forces her to seek remedies like Gust's energy potions. This stems from a desire to uphold an "ideal goddess" reputation while hiding hobbies like anime-inspired cosplay, voice acting, and guitar playing. She harbors loneliness and fears appearing friendless, reacting defensively to teasing. As Black Heart, she becomes assertive, competitive, and sarcastic, though this aggression softens in later games. Her narrative across the main *Hyperdimension Neptunia* series involves leadership challenges in Lastation. Early plots feature rivalries with other goddesses, including joining forces to banish Neptune during a Console War ceasefire. After memory loss, she repeatedly battles Neptune before regaining her identity and reluctantly allying against threats like Arfoire. Key developments include mentoring her sister Uni, pushing her to become stronger, and reconciling her competitive nature with genuine care for Neptune, admitting she cannot oppose her once seeing her face. In the spin-off *Hyperdevotion Noire: Goddess Black Heart*, she headlines a tactical RPG set in Gamarket—a world distinct from Gamindustri. She unites goddesses and generals (parodies of franchises like *Street Fighter* and *Metal Gear*) after their powers are stolen. Gameplay involves grid-based combat with elevation mechanics, trap hazards, and the "Lily System," where bonding adjacent units unlocks special attacks or transformations, often symbolized by kissing animations. The "Sim Noire" mode allows customizing her living space to unlock story scenes. Other media expand her background: drama CDs depict married life scenarios where she acts affectionately despite embarrassment, while anime/manga adaptations include recurring gags like Neptune crashing onto her. Non-*Neptunia* appearances include collaborations like *Azur Lane* (as a ship) and *Gun Gun Pixies* (as a guest). Combat-wise, she emphasizes balance, wielding rapiers in human form and broadswords as Black Heart. Signature techniques include rapid-slashing maneuvers like "Infinite Slash" and "Diagonal Blade Dance" (in Next form). She excels with firearms and possesses a fire-elemental affinity. Trivia notes her catchphrase "Lastation only does everything" mirroring PlayStation’s slogan, winning character popularity polls, design nods to *K-On!*’s Azusa, and her denial of playing video games despite manga depictions showing her with a Wii Remote.
