Jil and his party encounter another party that has practically been wiped out in a fierce battle against the ogres. There they manage to rescue an aged warrior called Gigi who was an acclaimed Guardian of the past. They take Gigi to a camping area on the way but are unable to take a moment of rest as they are plagued by one jam after another. One of the party members has a wallet pick-pocketed while a heated argument erupts between Coopa and Melt. In the end, reconciliation seems out of the question as Coopa, disgusted by her petulant master, decides to leave the party to be on her own!
On their journey Jil and the others pass a signboard indicating a shortcut. But the “shortcut” turns out to be a series of different traps that hinder their efforts to go forward. While one of the traps causes their gender to switch, the other forces them to wear animal costumes. Subsequently they arrive at the final gate. But getting through that exit door turns out to be harder they had ever imagined!
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.
Jil barely escapes from the scene of the King’s assassination thanks to the quick-wit of Neeba. The next day, the review of troops by the King goes on as scheduled. At the ceremony, Jil is dumbstruck; before him is none other than King Gilgamesh who he saw murdered the night before! Meanwhile in the city of Meskia, a giant slime that suddenly appeared was causing much havoc. A young girl named Coopa is embodied by the slime but is quickly rescued by Ahmey. When Coopa learns that Jil and the others are “Climbers”, she insists on allowing herself and her master, a mage named Melt, to joint their party.
Because of a blunder during his first battle, Neeba is forced to fire Jil from the group. Though disheartened by the humiliating dismissal, his desire to conquer the evil deity does not wane. As Jil wanders the city of Meskia which is filled with anticipation for the third season of expedition to the Tower, he meets a mysterious girl named Kaaya and a close-mouthed young woman called Ahmey. When Jil learns of the great hero King Gilgamesh’s visit to the city, he takes his new friends to watch the procession. There he accidentally comes upon the figure of Neeba in the bustling crowd.
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 armour 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!
