The legendary Tower of Druaga is resurrected eighty years after the hero Gilgamesh has taken it down. In order to destroy the evil deity Druaga, the Kingdom of Uruk dispatches its troops to the tower, but the expedition repeatedly fails in its efforts. A young man named Jil who has been blessed by the goddess Ishtar, is awarded a set of brilliant golden amour and a sword from Gilgamesh as tokens to defeat the maumet.

Sent off by the cheering crowd, our young hero Jil confidently sets out to confront the evil deity inhabiting the tower. Helped by great friends such as the archer Neeba and a Mage called Fatina, he heads for the uppermost floor of the Tower!

Jil and his party set out on their expedition among the other Climbers and face their first battle. However, their struggle against the powerful foe Kusarakk is harder then they had expected as their teamwork has not yet been refined to say the least. Ahmey is the only member who has experience as a Climber and they follow her confident guidance. They listen to her advice regarding battle strategies and numerous rules of thumb about Climbing. Now equipped with the necessary knowledge and skills, they resume to confront the Kusarakk again.
