Once upon a time, There was a small country called Ruriruli Kingdom. In that country, there was a princess named Puri Puri who was loved by everyone. On her 16th birthday, the King, Cocoa III had to decide on a marriage partner for his daughter. Puri Puri, who's dissatisfied with this custom, said, "I will be the bride of the person who climbs the Tower of Nouveau in the eastern forest!" The Tower of Nouveau is a forbidden tower with terrible complex traps and monsters. Cocoa III scolded Puri Puri for saying such things. The rumor spread far and wide and even reached the ears of the adventurer Totom who had explored various things in the past. He said, "That's interesting, and I'm also interested in the Tower of Nouveau," and off he went to conquer the tower.
