The Guren Isshiki (Japanese for "Crimson Lotus Type One") is a knightmare frame utilized by the Order of the Black Knights in Code Geass Megiddo. It is the knightmare type used exclusively by Zero Squadron.


The original Guren Isshiki, only with a white faceplate and the three-pronged surger originally used by the Guren Nishiki.


The original Guren design produced by Rakshata Chawla. Radically different from its Britannian counterparts, its technology is on par with most seventh generation Knightmare Frames, a fact that is a source of pride for its manufacturers. For armaments, the model possessed a small fork knife, a grenade launcher within its left arm, and a single slash harken. The Guren Isshiki's speed and strength were also well above that of earlier fourth and fifth generation knightmare types, but otherwise it was a fairly unremarkable design. Ironically due to this fact, Rakshata was able to produce not one but twelve prototypes of this machine, though much like the later Guren Nishiki and the Lancelot, they proved too advanced for mass production.

After being brought out of storage around 2018, Rakshata would upgrade these machines with features from the Nishiki. Among these upgrades was a radiant wave surger like that of the Nishiki, only with a three clawed configuration instead of the original's more humanoid design. This unit in turn is somewhat less powerful, but possesses most of its standard features, only missing the rocket harken and spray fire capabilities. It does, however, possess its own unique capability: it can fire microwave radiation bursts in a machine gun-like rapid fire configuration, allowing it to rain fire down on multiple targets at once. Besides the surger, the Isshikis were also given the same round of upgrades as their cousin.


The first incarnation of the Guren series, the Guren Isshiki (Mark I) was produced by Kyoto House some time in the 2010s, at about the same time as Britannia had developed the Lancelot. Originally it had been intended for the Japanese Liberation Front, in which the unit would have supplanted the organization's aging Burais (themselves only reproduced Britannian Glasgows) as the JLF's mainline knightmare; had that purpose been followed upon, the JLF would have been the first army in the world to wield newer generation knightmares en masse. Unfortunately however, the Isshiki held its generation's "curse": it was so advanced for its time that it was nearly impossible to produce in large numbers, at least to the extent the JLF needed. Thus production of the Guren Isshiki was cancelled and the initial twelve were stored in one of Kyoto House's secret caches in the Ryukyu Islands. Even so, Rakshata herself had not given up on the design (even though she herself found the Isshikis to be "imperfect"), which led her to eventually create the Guren Nishiki (Mark II).

Following the Devastation and the restructuring of the Black Knights in 2018, the Isshikis would be rediscovered by Rakshata and her compatriots. Easily seeing their worth, Major Kallen Kouzuki, the legendary "Red Dragoness" and pilot of the Guren Nishiki, would request Rakshata to modernize these machines and turn eleven of them over to her unit, 0 Knightmare Squadron "Rei" (Zero Squadron). Rakshata would more than follow up that request, upgrading the units with the same list of innovations she had made to the Nishiki and then turning them over to Kallen, who would spend the next year or so instructing her pilots in their usage. By the time the Black Knights entered the Great World War, Zero Squadron was widely recognized for their exclusive use of the Guren, as well as the ability to bring out the very best of their machines.

With Zero Squadron taking the initial eleven, Major Rai Sumeragi, known by his monicker the "Blue Thunder God" and his being a former Zero Squadron pilot himself, would take the twelfth and final unit. So that it would stand out from Zero Squadron's machines as well as be identifiable as his own, Rai would have his Guren repainted in his trademark cobalt blue. This in turn earned his machine the nickname Aoren (Japanese for "Blue Lotus").
