In a world where dragons dominate the skies and humanity remains confined to the ground, engineers of the Silvanna Republic develop experimental aircraft in a desperate bid to challenge the aerial supremacy of the dragons. The story follows Karl Schnitz, a young and passionate pilot chosen to fly the Blitzvogel, the world's first jet-powered aircraft. His ultimate goal is to surpass the Kaiser Drache, the fastest dragon capable of supersonic flight, in a high-stakes contest of speed and courage. The narrative unfolds during a time of war, adding layers of political tension and personal sacrifice to Karl's quest as he takes to the skies in his steel wings to prove that humanity can reclaim the heavens. Key narrative arcs involve the rigorous development and testing of the revolutionary Blitzvogel, Karl's initial encounters with the dragon threat, and the climactic attempt to outrun and outmaneuver the Kaiser Drache. The manga, illustrated by Anno Nanakamado, expands on the original light novel by Gen Urobuchi and ran in Shogakukan's Hibana magazine before moving to the MangaONE app, concluding with the pilot's final confrontation against the legendary dragon.
