Code Geass: Boukoku no Akito 4 - Nikushimi no Kioku kara

Definition

While W-0 is away, Leila and the remaining crew at base find themselves surrounded by Britannian Knightmares. Piloting the Vercingetorix, Shin Hyuuga leads the enemy charge, having usurped the position of Grand Master in the Knights of St. Michael. With her core members unavailable, it's up to Leila to protect her comrades, but this may be much tougher than she realizes: a spy lurking among them is finally ready to reveal himself.
