The Tower of Druaga: The Aegis of Uruk - Season 1 - Eps 9: Eleven Nine
Jil and his party enter an area supported only by thin pillars. They engage in a battle against a balloon-shaped monster called Barbar and, demonstrating well-coordinated team play, they defeat the enemy in the end, thanks to Melt's magical tricks. The festive mood from the victory, however, is short-lived as the feebly structured area collapses due to the explosion caused by Barbar's demise. The collapse of the area also extends to other areas on the same floor, thus causing Neeba's party and the Uruk Army much chaos. In the end, members of all parties find themselves separated from each other.

Synopsis
The Summer of "Anu": In a summer once every five years, demons in the mysterious Tower of Druaga lose their powers due to the magic spell cast by a god named "Anu". King Gilgamesh, ruler of the kingdom Uruk, uses the appearance of demons as an excuse to invade the tower and find out the construct's secrets. As 80 years passed, the Uruk army managed to fight back the demons and built a fortress city and safe haven on the very first floor of Druaga—Metz Kier. Thus begins the story of a warrior named Jil, who, finding companions along the way, embarks on a quest for the fabled Blue Crystal Rod, a powerful artifact rumored to be in the highest floor of Druaga. However, other competitors, including the kingdom of Uruk itself, want the treasure, all for their own reasons.
