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

Having exposed the Ark Fleet as a Britannian deception, Akito Hyuuga and the W-0 pilots storm the massive airship Galia Grande. Their assault leaves Weiswolf Castle dangerously undermanned, and Leila Malcal is unable to contact them when Euro Britannia launches a direct attack on the base.

Shin Hyuuga Shaing leads the offensive in his golden Vercingetorix, closing in on Leila and the remaining defenders while political betrayal spreads through the E.U. With the castle on the verge of falling, Akito races back toward a battlefield where his brother, his commander, and the hatred binding their past together are finally converging.
