Popokkuli and Seserukka were of Niellefresne's companions during the parade in an attempt to make him and his companions look like heroes to the townspeople, but the situation gets out of hand and ends up mortally wounding a man named Warburton. They are later seen when Corguevais is captured by two furious miners and the twins appear to stop the riot and also are present when the Niellefresne's plan is unmasked by Thancred. After Corguevais reveals the truth about the plan to Ascilia, Warburton's daughter, and try to take the girl back to Ala Mhigo. Niellefresne's group intercepts the flight of Corguevais who flees after calling a horde of coblyns leaving Ascilia behind, Popokkuli and Seserukka ride on chocobos and try to chase him in vain. The group discovers that Warburton had important information for Ul'dah's future, so Niellefresne tries to resort to necromancy to revive him but ends up murdered by a mysterious figure.
Popokkuli and Seserukka officially meet the adventurer in Nanawa Mines after he joins the Miners' Guild. Popokkuli and Seserukka demand that the adventurer prove his worth before they allow him to enter the mines. Once the adventurer returns with an ancient pottery fragment, Nenekko says it comes from an ancient city called Sil'dih and in exchange for the fragment, she agrees to convince Popokkuli and Seserukka to grant access to the Nanawa Mines.
After an arranged marriage between Nenekko and Fafajon is organized, Popokkuli and Seserukka try to prevent the wedding and with a group of adventurers leaves for Gridania in search of the groom. Popokkuli and Seserukka sabotage a gift that Fafajon had hidden but it is Nenekko who opens it. Reflecting on her life dilemma, Nenekko flees to Vesper Bay where she decides that she will focus her efforts on researching Sil'dih's civilization and asks the adventurer to warn his concerned brothers about her whereabouts.
After the calamity, unexpectedly Adalberta was chosen as the new guildmaster. Deep Canyon who believed he had been betrayed by Adalberta began to conspire against the Miners' Guild but his machinations were discovered and he ended up in a trial conducted by Amajina & Sons Mineral Concern. In the court Fyrgeiss, Popokkuli and Seserukka act as judges and gave their verdict once the misunderstanding is revealed.
Later when some invaders activated the ancient traps in the Sunken Temple of Qarn, Popokkuli and Seserukka ask the Warrior of Light to rescue Nenekko who was in danger in the ruins.
