Arfoire reveals her ambitions, which was a new system of government where anyone can rule. She then transforms into a CPU-like form and attacks Nepgear with the same moves the Hearts know. Seeing Nepgear being mercilessly hit by Arfoire, Rom and Ram discovers their powers and transform into HDD form. The transformed CPU Candidates try to strike Arfoire down, but she stands formidable. Trying to take Arfoire down, Uni focuses on her target and unconsciously transforms into HDD form, letting her land a shot on Arfoire.
Nearby, the subdued Hearts are gradually losing strength from the black force below them. Trying to free them, Compa distracts Warechu, while IF tries to get near the Hearts. She delivers a message to them from Histoire. Histoire informs them that the Anti-Crystals can also convert Share energy into Anti-Energy, which can also kill CPUs. Vert, Blanc, Noire, and Neptune eventually becomes repressed by the Anti-Energy.
Despite being repressed, the Hearts are still fighting to live. Arfoire was about to kill Nepgear when Nepgear sees lights coming from the Anti-Crystal prism and blocks her attack. The CPU Candidates focus their energy against Arfoire, negating the Anti-Energy she relies on and weakening her. They strike her down, and with Nepgear's attack, the prism formed by the Anti-Crystals shatter. Arfoire is defeated, and the Hearts are freed.
Somewhere, Warechu is able to rescue Arfoire and drags her along.
