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.

Sougetsu later reappeared in Chapter 13, at the end of Part 1. Disel, who lost the Sutherland Custom in the battle with Magdala, found the Sougetsu in abandoned transport truck, and they piloting Sougetsu again to counterattacking Magdala. In the end, Disel succeeded in repelling Magdala by destroying the left arm but Sougetsu also losing it's left shield in this battle.

At the events of Black Rebellion, Sougetsu have been transferred into Britannian's military base in Yokohama alongside other captured Black Knights's Knightmares. During Lost Zero Arc's Chapter 4, Kallen and others came to recapture Knightmares, C.C. stole the Sougetsu to escape Yokohama area.
