The Guren Mk-II (紅蓮弐式, Guren' Nishiki) was a prototype Knightmare Frame model designed by Indian engineer Rakshata Chawla, manufactured by Japan, and built by the Kyoto House. It is radically different from its Britannian counterparts, and its technology is on par with most seventh generation Knightmare Frames, a fact that is a source of pride for its manufacturers. The later Gekka models were based on the Guren's technology. Unlike Britannian-made Knightmare cockpits, the Guren Mk-II features an unconventional pilot seat shaped in the form of a motorbike seat, and a helm-like outgrowth surrounding its retractable head. The only existing unit is in the possession of The Order of the Black Knights and piloted by Kallen Kozuki.
