The Gekka (月下, Gekka, lit. Moonlight) is a new model based on the Guren and the Gekka Pre-Production Test Type. They were seemingly developed for mass production, but only five were produced as prototypes. Using the same motorcycle seat design, this Japanese-made Knightmare is the successor to the Burai Kai and boasts sixth to seventh generation technology, making them superior to Britannia's current mass production models, the Sutherland and Gloucester. The only five existing units are in the possession of the Four Holy Swords and their leader, Kyoshiro Tohdoh.
