The Burai (無頼?, lit. Rascal) is a remodeled version of the Glasgow mass manufactured by the Kyōto House. It is basically the same as a Glasgow but has elephant tusk-like cheekbones, giving the appearance of an oni. It is primarily used by the Black Knights, though the Japan Liberation Front also makes use of them. Lelouch pilots a customized unit with a crimson head module and golden horns resembling those on a samurai's helmet, and Kallen briefly pilots a red-painted version in the ninth episode. The Burai were phased out following the Black Knights' exile from Japan in favor of the Akatsuki.
Though similar in terms of armament, the Burai differs from the Glasgow in several ways. It lacks the hand-mounted Stun Guns and Tonfas of the Glasgow (though the ones seen in episode 12 do have the latter), but its hands have been refurbished so that they can guard, a feature exclusive to the Burai. It also features a torso-mounted antipersonnel machine gun. Like the Sutherland, variants exist including close combat and electronic warfare types.[18]
Kyoshiro Tohdoh and his subordinates, the Four Holy Swords, initially pilot optimized versions of the Burai called Burai Customs (無頼 改, Burai Kai?). The model has elongated head antennas which extend to the back of its torso, and Tohdoh's unit also has a distinguishing white head module[40] They carry the Katen Yaibatou used on the Gekka. The Burai Custom can match Britannia's Gloucester in single combat, however are less numerous. All five units were lost after the battle of Narita, at least one in direct combat with Cornelia's Gloucester, and the remaining presumably abandoned by their pilots during their retreat. Tohdoh and the Four Holy Swords switch to using Gekkas following the loss of the Burai Customs.
The Japanese resistance also makes use of the Raikou (雷光?, lit. Lightning), a massive coilgun built from four Glasgows or the Burai variants. It fires a high velocity shell which releases two-dozen ball bearings that tear through Knightmares with ease. The four Knightmares are arranged along both sides of the cannon for support, and their heads are attached to a circular disc on the top of the cannon for a 360 degree field of view. The cockpits of the two Knightmares on each side are linked to create a two-seater cockpit. In addition to the main cannon, the arm on the open side of each Knightmare is replaced with a linkable cannon, creating two secondary cannons in case the main cannon fails to destroy the target. Two of them are used in the series, the first by the Japan Liberation Front in the eighth episode and the second by the Black Knights in the finale. Suzaku Kururugi destroys both
