Synopsis
This special anime, screened at the Tokyo Skytree, shows a battle against the Colossal Titan. In this short, the Shingeki no Kyojin characters serve in the Sky Survey Corps, guarding Wall Skytree—a part of the walled city that houses the Skytree. The Sky Survey Corps discovers that Wall Skytree is besieged by a titan army, including an enormous 350 meter-class titan that has materialized beside the Skytree and stays immobile.
