A shattered battlefield. Smoke and debris fill the air. The once vibrant Gamindustri skies are now overcast, thunder rumbling as if mourning the fallen. Noire, Blanc, Vert— and even Nepgear— lie unconscious across the cracked ground. Their battle against the chaotic Rei Ryghts has pushed them to their absolute limits… and beyond.

Rei Ryghts (sneering): "How pitiful. Goddesses? More like obsolete relics. This is the end of your delusion, Neptune."

She hovers above the battlefield, a menacing aura crackling around her like a storm unleashed. Her hand rises, dark energy spiraling into a massive spear of raw destruction. Only Neptune remains. Bloodied, bruised, and barely able to stand, she staggers to her feet, wobbling like a noodle on a plate.

Neptune (panting): "H-Hey... you're gonna have to try harder than that if you wanna take me down... y-you dollar store villainess..."

She tries to force a smirk, but her knees buckle. Her gaze falls upon her fallen friends— Noire's broken sword, Vert's still form, Blanc's tattered cape… and Nepgear's outstretched hand.

Neptune (voice trembling): "...Everyone… you all… you trusted me. You fought for me. For Gamindustri…"

Rei hurls the energy spear.

Rei Ryghts: "Fade away, Neptune!"

Time slows. The world seems to freeze. In that moment— Neptune's heart surges. Memories flash: laughter with her friends, battles fought side by side, all the bonds she's built. A spark ignites deep within her soul— calm, yet blazing. Her body glows. The air stills. The energy spear halts midair, inches from her chest, as if the universe itself dared not touch her.

Neptune (eyes now glowing silver): "...No. I'm not done. Not until everyone's safe."

With a pulse of light, her transformation begins— faster, smoother, more ethereal than ever before. Her purple locks shimmer and shift to radiant silver, her eyes now glowing with serene intensity. A calm aura— pure, divine, transcendent— erupts around her. Her body morphs into her HDD form: Purple Heart, but unlike any before. Her human form clothes do not become her armor, but remain as the wind swirls around her, not with force, but reverence. Ultra Instinct Purple Heart.

Rei Ryghts (shocked): "W-What is this?! This isn't normal HDD— this is… something else!"

Purple Heart (voice calm, but powerful): "This is what happens when you push a CPU too far. When you hurt the people I care about. I've stopped thinking… my body moves on its own now."

She raises her hand. The energy spear crumbles into glittering dust before it can touch her.

Purple Heart (eyes narrowing): "Now… it's my turn."

In the blink of an eye— no flash, no flare— she vanishes. Rei's eyes dart around in confusion. A whisper of wind. Then— BAM! Rei is sent flying across the battlefield by a single strike to the gut she didn't even see coming. She crashes into a cliffside, rubble burying her. Neptune floats above, expression composed but fierce.

Purple Heart: "For Gamindustri… and for my friends… I'll go beyond even the Goddesses."
