In the second season, the Guren Mk-II receives a mid-battle upgrade through a series of rocket-mounted attachments. The upgraded model is dubbed the Guren Flight-Enabled Version (紅蓮可翔式, Guren Kashōshiki?, lit. Crimson Lotus Aerial-Type). It gains an integrated Float System and antenna on the sides of its head which carry a radiant wave surger-based shield, as well as a new "armor-piercing bombardment-type" radiant wave surger arm. The new arm has a dark gray forearm with silver fingers. In addition to its close-range blast, the new radiant wave surger arm can also fire a concentrated long-range beam or a wide-range blast. The long-range beam can eliminate multiple targets in a single shot. The wide-range blast, though not as destructive, cripples any Knightmares caught in it, and can still destroy weaker craft such as helicopters. Another addition to Guren's arsenal is the 'Gefjun Net', a series of small, fast-moving drones launched from the back of the Guren that surround an enemy Knightmare and release a Gefjun Disturber surge, immobilizing it
