S1·E22 Extreme Brave

While the Macross Elysion leads an attack to draw the Aerial Knights' attention, Walküre and the Delta Flight start their operation to infiltrate Windermere and destroy the device that controls the Protoculture ruins to put an end to the war. However, the Aerial Knights see through their diversion and launch an attack on them nonetheless. Hayate, Mirage, Arad, and the members of Walküre manage to slip past the dimensional barrier into Windermere, but Kassim follows them close and he burns out the last of his energies in a desperate effort to stop them.
