Ep. 1: Misaki se sincroniza con la IA y se transforma en un Ghoul durante una crisis en la expedición al Núcleo.

1

The series begins with a dangerous expedition being sent into the Core. A Ghoul is in the process of materialising, but the station's Quantum Barrier is still being repaired and is unable to contain the process. Prim calls Misaki in for a "final physical", but instead, her brainwaves are synchronised to an unknown artificial intelligence system. She appears to enter her Rampart Armor (R.A.) mecha along with Kiri and Kotoko, and even Lyar, who changes the battle plan to include herself. Three of the pilots are dispatched, but Misaki is unresponsive and remains behind while Prim determines the problem. In the battle that ensues, Kotoko is destroyed(but not truly dead since her mind and memories survive) and Lyar and Kiri are disabled. Misaki finally joins the battle, rescuing them but being caught herself. Facing certain death, she panics, and transforms into a Ghoul-like being that grapples with the Ghoul until both are destroyed in a burst of light known as pair annihilation. Back on the ship, Prim and Jean-Luc seem to be the only ones who know what really happened; they monitor the exhausted real Misaki, suspended in a chamber connected to numerous wires.
