Arfoire reveals her ambition to introduce a new system of government where anyone can rule, then she transforms into a CPU-like form to attack Nepgear with the same moves the Hearts know. Seeing Nepgear being mercilessly hit by Arfoire, Rom and Ram discover their powers and transform into HDD form. The transformed CPU Candidates try to strike Arfoire down, but she stands formidable. Wanting to help, Uni focuses on her and unconsciously transforms into HDD form and striking Arfoire.
Nearby, the subdued Hearts are gradually losing strength from their power being sucked out of them. Trying to free them, Compa distracts Warechu while IF tries to get near the Hearts.

Vert, Blanc, Noire, and Neptune eventually becomes repressed by the Anti-Energy.
Despite this they continue to fight and refuse to give up their will to live. Arfoire is about to kill Nepgear when Nepgear sees light coming from the Anti-Crystal prism that 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.
