The famous original conqueror of Druaga.

Gilgamesh (ギルガメッシュ, Girugamesshu?), also known as Gil, the destined hero of the game. He has been charged by the goddess Ishtar to ascend the Tower of Druaga and rescue the maiden Ki from the demon Druaga. Not only must Gil use his sword and shield to navigate through the labyrinthine floors of the tower, he must use his wit and memory to reveal the locations of the treasures contained on each floor, some of which are absolutely necessary for Gil's success. Gil is patterned after the Gilgamesh of Sumerian legend. Gil was also absent in The Quest of Ki. (Wikipedia)
