Code Geass: Rozé of the Recapture

In the seventh year of the Kowa Period, the former Hokkaido Block lies under the oppressive control of the Neo-Britannian Empire. Within this occupied territory operate two mercenary brothers known as the Nameless Mercenaries. The elder sibling, Ash, possesses extraordinary athletic prowess and exceptional skill in piloting Knightmare Frames. His younger brother, Rozé, serves as the tactical mind of the duo, utilizing his sharp intellect to gather intelligence and formulate strategies. For four years, the region has been sealed off by an impenetrable energy barrier known as the Situmpe Wall. Behind this shield, Callis al Britannia, the 100th Emperor who previously crushed the Black Knights' liberation efforts, plots to plunge the world into chaos once more. Aided by his loyal servant Norland and the formidable Einberg Knights, Callis continues to tighten his grip on power. When a critical request reaches the brothers, they are drawn directly into the heart of the conflict. Teaming up with the resistance faction known as the Seven Shining Stars, Rozé and Ash launch a daring campaign against the Empire. Their ultimate objective is to confront Callis's forces and recapture Princess Sakuya before the emperor's destructive ambitions can be fully realized.
