Sougetsu

The Sougetsu (蒼月, Sōgetsu, lit. Blue Moon) is a Knightmare Frame appearing in the game Code Geass: Lelouch of the Rebellion Lost Stories. It is piloted the the main protagonist.

Design and Development
The Sougetsu was built by modifying the prototype Gekka. The left arm Radiant Wave Surger has been replaced with a new arm with a shield-claw weapon that can be used for both defense and offense.

Operational History
The Sougetsu first appeared when it was delivered to the Black Knights from Kyoto alongside the Guren Type-02, and given the protagonist to pilot. Along with the Guren, it plays a key role during the Battle of Narita, where its main role was to engage with Andreas Darlton in battle and prevent him from reaching Cornelia during Zero's planned ambush. Prior to that, it fought with Britannian soldiers that it lured into the range of the JLF's artillery to give it an edge while outnmbered.

When the Lancelot shows up and its disruption renders the Black Knights unable to achieve their goal, it goes to Zero's aid and rescues him when his Burai is shot down. It then engages with the Lanelot in battle, though is at a disadvantage due to its dwindling energy. It is eventually disabled when the pilot becomes injured within its cockpit. It is later recovered by Zero, who uses it to transport C.C. and the protagonist to safety. Following the battle, it is fully repaired at the Black Knights HQ.
